Jeremy answered through the closed door. "Uh...Ok, mom..I'll be out in a little bit!"

His voice sounded odd. I couldn't really define why. Just call it motherly instinct.

"Jeremy?" I said, "Is everything alright?"

There was a pause. "Yeah, sure mom. No problem." But I thought I detected a note of fear or nervousness in his voice.

I thought for a moment and then decided that my responsibly as a parent took precedence over his privacy. "Jeremy, I hope you have clothes on, because I'm coming in!" I turned the knob and opened the door.

He was lying on the bed in his usual t-shirt and boxers. He quickly pulled up the covers to cover himself, but not quite quickly enough. My face felt very hot and I knew I was blushing.

"Oh! I..uh" I stammered, deeply embarrassed. "I'm really sorry!" What I had seen was his erect penis protruding from the fly of his boxer shorts. He was obviously either masturbating or just about to. I averted my eyes and started to close the door.

"Wait!" he said in a plaintive tone, "I think I got a problem...I-I don't know..I-I'm not sure how..."

I stopped, confused. Surely, every teen boy knows how to masturbate! I looked at him, trying not to look at his penis. "Uh..don't know how to what?"

"It won't go away!" he blurted, sounding close to tears. "It's been..like this..for a couple hours!"

I tried to sound calm, but I knew I was still blushing. "Well, did you...did you finish?"

Now he was blushing too. "Kinda, but not a lot. Not like it usually is." He looked at me helplessly and blurted out, "I took one of Dad's pills! One of those little blue ones! I just wanted to see what happened!"

"Oh no! You didn't!" I almost yelled. Jim, my husband, had been having some problems getting erect and had gotten a prescription for the famous 'little blue pill'. "Jeremy! How could you be so stupid! And you were snooping in our bedroom!"

He looked away, shamefaced. "I'm really sorry! I'm scared! What do I do?"

My brief anger turned to concern. "And..well..doing the usual thing doesn't..uh..make it go away?" He shook his head. I tried to think clearly. "I'm going to have to call the doctor!" Jeremy blushed more deeply as I picked up the phone on his desk and dialed Dr.Blakeslee.

The nurse put me right through. The doctor listened to me and sighed, "Well, there is an injection that will reverse the effects, but it really hasn't been approved for use on someone his age. Yet going on too long in that condition can injure the penis." He paused. "Brenda, I don't know how to put this delicately, but does he have a girlfriend?" I understood his meaning and was more than a little shocked, "Not THAT kind of girlfriend! He's only 15!" The doctor sighed again, "Well, I know sexual intercourse can provide enough stimulation and the necessary orgasm or orgasms to relieve the problem."

"Isn't there anything else that will help?" I asked, feeling helpless.

"Not really. The injection or intense stimulation are the only two solutions. You could wait it out but that could be risky." he hesitated. "Tell you what. Why not..well..just wait and relax..consider the situation for a while. Call me back if you need to." I was confused at first. He seemed to be abandoning us....but then I understood what he was trying to say.

"I-I understand doctor, thank you," I said somewhat numbly and hung up.

"What did he say?" Jeremy asked hopefully. I didn't know how to answer him. I sat down on the edge of the bed. Even though he'd pulled up the covers, his erection was still obvious.

I took a deep breath. "Well, basically, honey. He said that this is a problem that we..that we have to solve on our own." I told him what the doctor had said. His face fell.

"But I-I don't know any girl THAT well! I never even did 'it'..honest, never!"

I shifted uncomfortably. I didn't know how to say what I had to. Taking another deep breath, I looked up at the ceiling and said, as calmly as I could. "Honey. most girls your age are still virgins and it wouldn't be right to use them that way. But..well..I'm a female and..well..not a virgin"

"Oh Jeez!" he exclaimed. "You mean, I'd put it in your...I mean, have sex with you?" I could only nod and say "We can't tell your father"

I pulled the covers down and this time really looked. His swollen penis pointed straight up his belly. It looked a bit larger and thicker than his dad's. I reached out with a trembling hand and touched it, then wrapped my fingers around it. I was surprised by its hot, almost steely hardness. Had Jim's EVER gotten that hard? The moment was quite awkward for both Jeremy and me.

"I think I'm going to go over to my room and..well..get ready," I said quietly. "When you think you're ready, you can come over..Ok?" He nodded. I felt an increased throbbing in his shaft just before I let go it and left the room.

In my bedroom, I undressed quickly, trying not to think too much. I tossed my panties onto the floor and looked at my naked body in the mirror. For 38, I think I still look Ok, but I should exercise more. The big globes of my 38D breasts hang a bit now but aren't too floppy. My hips have widened after two kids, giving me more of an 'hourglass" type figure. I was a bit embarrassed by the untrimmed thatch of dark brown hair between my legs, but figured it really made no difference now.

I wasn't ready. My wide dark nipples were relaxed. I put my hand between my legs and pushed my middle finger up inside me, finding myself damp, but not wet. Just then, Jeremy appeared in the doorway, staring in fascination. He was naked now, his manhood pointed straight out in front of him. I quickly pulled out my finger.

"I'm not quite ready..inside, I mean," I said sheepishly. Jeremy looked confused. I sat down on the bed.

"When a woman is ready for sex, she gets wet, down here," I explained, placing my hand on my crotch. "It lubricates me so a penis..your penis..can slide in easily." He nodded.

"Can I help you get ready?" He asked.

I balked at first, but then realized that was silly. "Yes..yes you can," I said, pulling myself up onto the bed and reclining on my back. "Lie down here beside me."  He did and I closed my eyes and opened my legs.

"Ok, honey. Reach down between my legs where the hair is." I felt his hand on my bush and suppressed a startled jerk. "Yes, there. Now down further. Feel that fold of skin? You know what that is, don't you?"

I felt him probing the slit as he said, a bit breathless, "Yes, it's your cunt." I didn't correct him. Nice language seemed silly by that point.

"Push your finger in the slit..uh..yes, but down further, more towards my butt..oh!..there! Push it up that opening." His finger went up inside me. I opened my legs further. "Yes. That's good. Now, move it in and out."

I think he was trying to shock me as he asked, "I'm fingerfucking you, aren't I?" I answered casually, "Yes, honey, you're fingerfucking me."

I felt his other hand on my right breast. A tentative squeeze. "Suck the nipple", I encouraged. "That helps too." Almost immediately, eagerly sucking lips pounced on my nipple. He pulled his finger out of my cunt and began playing with my other breast.

"Man, you got nice tits, Mom!" he said as he moved his face to my left breast. His other hand moved back between my legs and found something new. My hips jerked.

"What's that? What's wrong?" he asked.

"My clitoris..its very sensitive" I answered.

He moved his face down below my belly. "It's standing up, Kinda rubbery," he observed.

"Yes..I'm..I'm becoming aroused," I said, frankly surprised.

I heard him breathing more heavily and felt him swing his leg over me. I thought he was preparing to mount me and kept my eyes closed, my heart racing. Was I doing the right thing? All this was SO forbidden! But then I felt him up further on me, almost sitting on my breasts.

"Jeremy? What are you..." I opened my eyes to see his hard penis hovering over my face. He had one knee planted under each of my armpits.

"Suck my cock!" he demanded in a hoarse, unfamiliar voice. "Suck it!"

"Jeremy! I'm your mother! You....AUUGHH!" His response to my protest was to push his cock into my mouth and nearly down my throat, almost gagging me. He immediately leaned forward, his hips over my face. His hips began pumping frantically. "Oh yeah!" he breathed, "Oh yeah! facefuckin' ya!" I was near panic, but he had me pretty well pinned. I real can't 'deep throat' very well but with Jeremy, I had to as he forced the head of his penis down my throat. I felt his hairy balls squash against my chin each time he thrust downward. Suddenly, his pumping became very rapid, almost frantic. He was going to come in my mouth! I tried to protest but could only manage a gurgle.

"Ohhhh shit!" he gasped out. There was a great, hot flood in my throat and mouth. I couldn't breathe. There was so much that I couldn't even gag. I was literally drowning in my son's sperm! I heaved my hips and shoulders but he kept pumping away, spurting more and more. It poured out of my mouth and down my chin and cheeks. My vision got fuzzy and just as I felt I was going to pass out from lack of oxygen, he fell off me to my right, pulling his cock out and shooting the last of his load straight into my face.

I rolled to the other side of the bed, gagging, coughing and spitting out what seemed to be a gallon of cum onto the carpet. I lay there with my head hanging over the side of the bed, trying to get my breath.

"Wow Mom!" Jeremy said. "That was great! I didn't know you could suck like that!" I still couldn't breathe well enough to respond. I remember hoping that I had taken care of his 'problem' at least. But I was soon to be disappointed.

I was lying on my stomach. Without further comment, he grabbed one hip and rolled me onto my back. As he pulled my legs apart, he said "Oh yeah! Now let's get some of that pussy!" I started to say something...I don't remember what, when he scooped up my legs and stuck his cock in me..all of it at once.

"Oh God! Jeremy! Easy!" but he had again gone deaf,it seemed. "Yeah! Yeah!" was his only response, "Shit this feels great!" He slammed it in and out. The bed creaked and groaned as my breasts bounced all over my chest. I felt him swelling up bigger and hotter inside me but I didn't believe he could come again so soon.

As his pumps quickened, my own hips began lifting to meet him. "You likin' this Mom?" he asked in a surprised and pleased voice. I didn't answer, feeling both shame and pleasure, but I did hug him close.

"Don't..come..yet..not quite..yet," I panted in his ear. His pumping and the heavy smell of his jizz on my face drove me over the edge and I erupted in a bucking, groaning orgasm.

"Oh shit yeah! You're comin' !" He exclaimed. I could hear the surprise and delight in his voice as I came with a ferocity I hadn't felt in years. I thought I'd faint from the intensity of it, which was enhanced by feeling his organ spurting inside me.

I lay there limp as he gave a last few pushes before dismounting. He lay quietly behind side me for a time. I was too spent to look to see if his boner had subsided, but I soon knew that he hadn't.

"Roll over on your tummy, Mom," he said, pushing on my hip. Dreamily I complied, not realizing what he had in mind until I felt his finger between my buttocks. "Ever had it up the ass?" he asked eagerly. "Only a couple times," I answered groggily, "Your father doesn't like to do that." I felt his finger go up my anus roughly, making me gasp. "It's nice and tight!" he admired, as he worked his finger in and out.

I came to my senses as I felt his weight on my back. "Wait Jeremy! You can't just shove it in! I need..." and then I groaned in protest as he forced his penis up into my rectum. He began humping as rapidly as my asshole would permit. I groaned and squirmed beneath him.

"Jeremy! It hurts! Pull it out!" I almost screamed, but already a tingling pleasure was coming through the pain. My buns jiggled in time with his thrusts. I felt like I was going to pee and put one hand beneath me to grasp my pussy to hold it in, but I was soon masturbating. The pressure did make me pee a little, it dribbled through my fingers as I humped my hand.

Then a voice said, "Oh my god! Oh my god!"

I was able to twist my head around enough to see my daughter Julie standing in the bedroom doorway, her eyes wide and mouth open in utter shock. My feet pointed toward her and I knew she had a clear view of her brother sodomizing me. I had totally forgotten that her girlfriend's mother was bringing her home from the mall!

Of all the things she could have said, what she blurted out was totally unexpected: "Does that hurt?"

I just shook my head.

Jeremy became aware of her and suddenly yanked his penis out of my rear. Julie's eyes widened even further as she stared at her brother's erection. She didn't move as Jeremy leapt off the bed and grabbed her arm. He roughly flung her onto the bed but she raised no protest..seeming stunned. When he unsnapped her jeans and attempted to pull them down, she yelled "Don't!", grabbing her jeans just as her bright blue panties were starting to show.

"Jeremy, no!" I yelled, "You can't do that!"

His eyes were wild, "Why not?" he said, "She's got a pussy...she even showed it to me! Teasing me!" The blush on Julie's face confirmed what he said. She suddenly released her grip on her jeans and Jeremy yanked them off her in one movement, knocking her shoes off in the process. As She tried to  get up off the bed, he grabbed her top by the lower back and jerked it up over her head. Her bra catch let go and both her flailing arms instinctively tried to cover her exposed small breasts instead of holding onto her clothes, allowing him to finish pulling off her top and bra.

Her eyes had a wild look as she tried to keep him from tearing off her bikini panties, but the flimsy material ripped easily. Jeremy tore them off her and flung them behind him. They flew clear out into the hallway, their tattered remains fluttering like a blue butterfly.

She made only a half-hearted attempt to cover the neat triangle of hair between her legs. It was the exact shade of brown as mine. She scooted across the bed away from him, stopping as she got next to me. She looked at me with shock and an odd fascination in her eyes.

"He's going to fuck me" she said, rather quietly. Her legs were open slightly and I could see the slit of her vagina.

"Jeremy!" I scolded. "She's a virgin. And you could get her pregnant!" But Jeremy advanced on her, taking her shoulders and pushing her down on the bed on her back. Her eyes darted between his face and his hard cock. "It-it won't fit!" she said, mild fear in her voice.

I know I should have stopped it, but the atmosphere in that bedroom was charged with lust. I've never felt such electricity. "Yes it will, dear," I said soothingly. I slid my hand over her thigh, bringing it to rest on the fuzzy hump of her young pussy. I massaged it gently. "Mom..." she started to say. "Shhhhh!" I hushed and lowered my face to suck her left nipple, making its flower petal softness change into a rubbery erectness. "Oh.." she said softly as I felt her body lose its stiffness. I took my hand from between her legs and wiped it against my own crotch, making my fingers wet and shiny. I put my hand back between Julie's legs and rubbed the wetness into her pussy, then slipped my finger up inside her tight vaginal opening. I worked the dampness into her and, as her own wetness started, her hips moved gently. I briefly sucked her other nipple then kissed her on the lips. I looked at Jeremy.

"You can take her now," I said.

He had been watching us, but now he came back to life. He laid on top of her. She looked fearfully into his eyes, but loosely put her arms around him and let her legs slide open wide. I saw the head of his cock push against her crotch, but knew it was too high. I reached between them, took his shaft in hand and moved it down slightly. "It's right there," I said, "Push slowly!"

He pushed and Julie gasped, "It's going in!" Then her head went back and she gave a short scream. I knew my daughter had just lost her virginity. "Owwwwwwww!" she complained softly, "Take it easy!" and, surprisingly, Jeremy did go slowly. But he relentlessly pushed his penis into his sister's vagina. "Draw your knees up, honey," I encouraged, "It'll help it go in!" She obeyed and I saw a few drops of blood on the bed beneath her butt, a result of her broken hymen. When two-thirds of his shaft had disappeared between the stretched lips of her cunt, she grunted "I can't take any more!" Jeremy began to pump, forced to go slowly by her tightness.

I know it sounds terrible but I laid there and masturbated as I watched my children fuck. Julie looked over at me and smiled, the flush of her face spreading down her chest as her arousal increased. Soon her hips were rising to meet his pumps and she wrapped her legs around his waist. He seemed to be fucking her brutally but she kept gasping encouragement so I said nothing.

"Jeremy, don't come in her," I said, knowing it was futile to tell him that. His hips soon began jerking motions. Julie's eyes flew open wide. "I can feel it!" she said with delight, "I can feel him squirting in me!" Already I saw a dribble of white ooze out of her, running between her small buns, across the pink pucker of her asshole. Jeremy seemed almost done when she came, holding him in a bear hug and giving rapid pulses of her hips. I came as I watched her.

Finally, he rolled off her and she lay limp as a rag doll, legs wide open, his sperm gushing out of her stretched cunt. I looked at Jeremy and sighed with relief. His cock was finally limp!! He was completely exhausted.

Of course we never told Jim about what had happened. Not about that or subsequent 'sessions'. Thankfully, Julie didn't get pregnant and I got her on the pill, telling Jim it was to help 'female problems'..he didn't ask for details. I had thought Jeremy would prefer Julie over me, but he's in bed with me more often than with her. Julie tends to be a bit fussy about letting him come in her mouth and is still adjusting to taking it 'in the back door', as she puts it. And oh yes, Julie and I have enjoyed each other further..we tend to do that when it's just us at home.

Hard to believe that a little blue pill caused all this. When Dr. Blakeslee asked about it, I just tell him that everything worked out just fine!

I eagerly opened my mouth and accepted my sister’s hot urine. I’d been thinking about this humiliating chore all day too.

Hardly any of it ran down my chin this time and all I had to do was wash my face when she was finished.

Then Shannon led me back to her room and told me to lay down on the bed face down.

While I was climbing up on the bed I saw some things she had lined up on the bedside table. My hard dick spasmed in fear and anticipation.

Shannon went to work tying my wrists and ankles to the posts of her bed. Then she stopped to admire her work, running her hand up and down my naked back.

“Big strong man. All tied up and at his little sister’s mercy.” She mused. “Well, let’s get started, Stevie!”

She picked up a ping-pong paddle off the table and swatted me on the butt with it. It hurt but it wasn’t that bad. Of course any spanking would hurt bad if it went on long enough as she’d proved yesterday but she quickly got bored with the ping-pong paddle.

She stopped and pinched my ass. “Your cute little butt’s turning a pretty shade of pink but I can tell this isn’t hurting you much, Stevie. Let’s move on, shall we?”

“Yes Mistress.” I sighed.

Next she picked up one of her shoes. Not the high heels but one of her usual sneakers. She smacked my already slightly paddled butt and I gasped with pain.

“Now that’s more like it, big brother!”

She paddled me with the shoe for a while. It was really starting to hurt. Tears filled my eyes and I squirmed around and every time I gave a yelp of pain she giggled.

“Okay, that’s enough of that. Let’s get serious here.”

She put down the shoe and picked up a thin, springy branch she must have gotten off the tree out back.

It whizzed through the air and cracked against my tender buttocks. I screamed.

“Ooh-hoo-hoo! I just came, Stevie! Your screams are such a turn on! I want more!!”

She started to whip my butt, back, and legs. I did scream a lot. And begged her to stop. But of course she didn’t stop until she was satisfied.

“Mmmmm that was fun! Moving right along…” She picked up a belt. I was pretty sure it was mine.

“Please Mistress! No more!”

She only giggled and whipped me across the ass with the thick belt. I screamed louder than ever. My ass was already so sore and the belt was a whole new and terrible sensation.

Shannon continued to hit me with the belt. Luckily she seemed to realize that I couldn’t take much more so she didn’t do it for very long. Still I could feel a fresh painful set of welts on my back, butt, and legs.

“Just one more to go, slave. You’re doing great!”

She picked up her jump rope. It was the kind where the rope is a thin rubber tube. I groaned. She giggled.

She whipped me across the shoulders and I screamed long and loud into the pillow.

She pulled the pillow out from under my head. “I want to hear those screams, big brother.”

She whipped me and whipped me. I screamed and begged and cried. Finally she stopped, out of breath.

“Man! I got really carried away! I just love the way you scream and writhe around and are completely helpless while I hurt you! God, I need a picture of this!”

She went to her desk and grabbed her camera then clicked several pictures of my ravaged back side.

She came around the side of the bed and untied my left hand. She guided it between her legs.

“Feel how wet that got me, Stevie!”

Her panties were soaked. I knew she’d cum a few times while she whipped me but I had no idea how many.

She reached under me and grabbed my raging hard-on.

“Ooh hoo! And I see it turned you on just as much!”

It was true. I was in agony but the ordeal had made me horny as hell and dying for my sister to fuck me!

She untied me and told me to stand up.

She picked up the belt again. Oh shit.

“Now don’t you move.”

“Yes Mistress.”

I stood with my arms at my sides as she whipped my chest and shoulders. It hurt like hell and I had to use all my will power not to cringe away from her blows.

Then she raised the belt and brought it down hard on my up thrust dick.

I screamed and leaned over, grabbing my abused cock.

“I told! You not! To move! Dumb-ass slave!” She punctuated each word with a hard blow against my back as I fell to my knees still protecting my dick.

She whipped me down on my knees for another minute then walked around in front of me.

She stood there silently and I realized what she wanted. I leaned forward and kissed her shoes.

“Thank you for disciplining me, Mistress.”

She got me her homework and sent me to my room. I had a lot of difficulty finding a comfortable position sitting or laying. I had a hell of a time at dinner with mom sitting on the hard chair and trying to act normal. Shannon acted unusually cheerful at dinner. Of course I knew why.

A while after dinner she stepped into my room and told me to get on my knees. She slid down her shorts and black panties(still the same ones) and pissed in my mouth. I didn’t spill a drop this time. She left without a word.

She did that again during the evening and once more before bed. She wasn’t even using the toilet anymore! Tomorrow was Saturday and I just knew she’d be pissing in my mouth all day long. The idea was thrilling and terrifying.

That night I waited for her naked on the bed feeling every ache in my back and ass against the sheets. It had been an incredible experience but I hoped she realized I couldn’t take that kind of punishment all the time.

Shannon slipped in wearing only her dominatrix getup again.

“Hello Mistress.”

“How’s the back, big brother?”

“It hurts.”

“Aw, poor baby. Lemmee see.”

I turned on my side to give her a view of my back.

“Oh wow that’s hot!” She gasped, tracing welts with her fingers, awakening new fire in them. Then she grabbed my shoulder and pulled me onto my back. “God I’m so fucking horny!”

She tied my wrists above me again and also tied my feet just like she‘d tied me to her bed only face up this time.

She dropped her panties and crawled up on top of me. She immediately slid back onto my dick and started fucking me. No foreplay this time.

Then just as it was getting really hot she got off my dick. She stood and shoved her dripping cunt in my face.

“Lick, slave!!”

I was caught up in a haze of lust and felt like I needed to cum more than I needed my next breath. She had to smack me on the head before I obeyed.

My sadistic sister got off to three orgasms on my tongue then she climbed off the bed.

“Mmm, that was fantastic! See you tomorrow, slaveboy.”

“Mistress! Please!” I yelped.

She giggled and turned back toward me. “No, sorry. You won’t be cumming tonight, Stevie. But I’m not completely heartless.”
She grabbed the black panties off the floor and pulled them over my head, positioning the front patch right over my nose.

“There ya go!”

She’d been wearing those all day, including when she whipped me, and they were saturated with her musky scent. Smelling them all night without being able to get off would be torture!

She kissed me on the cheek. “Nighty night.” And she was gone.

That night was pure hell. I hadn’t cum for twenty-four hours. That was a pretty long time for me but with my sexy, sadistic sister teasing and torturing me it was unbearable. And I had to spend the entire night tied to my bed inhaling the extraordinary scent of her pussy. I didn’t sleep a wink.

Finally in the morning Shannon came back. She was wearing a nightgown and looked like she‘d had a good night‘s sleep.

“Mistress, please! Please!!” Was the first thing I gasped.

She giggled and patted me on the head. “Your begging is so cute, Stevie!”

She undressed and took the panties off my head. Then she climbed up on the bed, positioning her crotch over my mouth. I knew what was coming of course.

“Open up.”

While Shannon peed in my mouth I realized I had to pee pretty bad myself. But even more than that I needed to cum!

She sat down on my stomach and leaned forward with her elbows on my chest and her chin in her hands looking all cute and innocent. “Gee, I guess you reeeeeaaaaally want to cum by now huh, Stevie?”

Her fantastic little butt bumped against my dick.

“Yes Mistress! Yes please!”

She giggled. “Alright. I guess you’ve been a good little slave. Just remember it‘s a privilege granted to you by your Mistress.”

“Yes Mistress! Thank you! Thank you!” I sobbed.

She untied me and then told me to stand up and jerk off. “Put on a show for me.” I’d wanted her to fuck me but I was so damn horny right now I really didn’t care!

I stood and started pulling my dick faster and harder than ever. It wouldn’t take more than a second. Shannon crawled up and got comfortable against the pillows.

“Don’t cum too quick. Make it last. Squeeze it!”

Shannon made me perform for what felt like hours but it was actually only a few minutes. Then she told me catch all my cum in my hand and lick it up. I came harder than I ever had in my life. My whole body felt weak and I collapsed onto my knees but I still managed to catch all my cum and not spill it when I fell.

I obediently licked up the cum in my hand and then crawled to my sister.

“Thank you, thank you, thank you, Mistress!! I’ve never felt anything like that! It was so amazing! I love being your slave! I love it, I love it, I love it! I love you!!!”

I sobbed and kissed her bare feet worshipfully as I blubbered.

She giggled. “Alright, alright, Stevie. Now come up here and lick you little sister’s pussy!”

After I got her off several times she finally let me go to the bathroom and then we showered together again. The water brought new agony to my whipped back.

Then my Mistress allowed me to go back to my room and get a little rest. I wondered what the rest of the day would bring…

I really don't know what to do with this next without making it repetitve. Not sure if it will continue.

On that fateful day I came home from school as usual. I wanted to get on my computer and jack off to some of the hot pictures for a while.

I walked into my room and was startled to see Shannon sitting at my computer. I was about to yell at her for using my computer without permission but I suddenly saw what was on the screen. It was a video of a woman paddling a naked man’s ass.

She’d found my stuff! My face flushed and I wanted to run. I actually felt faint. What was I going to do??

She turned to me. “You sure do have a lot of this stuff, big brother.”

My mouth was dry as sand. I couldn’t talk.

“I’ve been looking at it for a couple of months. It’s really sexy.” She glanced back at the screen where the guy’s butt was getting very red. “Would you like a girl to do that to you, Stevie? Would you like me to do that to you?”

I still couldn’t talk. Had she really just said what I thought she’d said?

Her voice hit me like a slap, bringing me partly back to my senses. “Answer me, big brother!”

I swallowed the lump in my throat. “N-no. Shannon, you…”

She turned and smiled at me, her big brown eyes gazing into mine, drilling into me.

“Well, let’s just find out. Take off your shirt. Now, big brother!”

I was trembling. Was she serious? She knew about the stuff on my computer now. Knowing my secret she seemed to have an incredible power over me. And she was acting so dominant! I’d never seen her like this!!

I pulled my shirt off over my head and dropped it on the bed.

“Very nice. Now the pants.”

“I-I-…Shannon…”

“Now, big brother.”

“I-I’m not wearing underwear.” I mumbled out. Could this possibly be more embarrassing??

She giggled. “Perfect. Get them off.”

Now I realized I had a boner! My little sister ordering me around like this had gotten me hard!!

My hands were trembling so hard I couldn’t grab the button at first. Tears slipped down my cheeks. So this was what it was like to be dominated. This is it. A woman’s dominating me.

My hard dick popped out of my pants. I lowered them and kicked them off, looking down at the ground.

Shannon reached out and took a hold of my dick. I let out a soft whimper but didn’t even think about trying to stop her.

“Wow! You sure are hard, big brother. Do you like being bossed around by your little sister?”

“Y-yes.” I gasped.

“Good boy. Now get on your knees.”

I did as I was told. She stood up in front of me and I gazed down at her sneakers, wondering what she was going to do next.

She stood there silently, letting the tension grow. I was getting more and more afraid of her by the second.

Finally she said. “Look at me, Stevie.”

I slowly looked up to her beautiful face. She was gazing down at me with a superior smirk on her face.

“Do you think I’m pretty, Stevie?”

“Yes Shannon.”

She slapped me. “You should know the rules, Stevie! What do you call a woman when you’re kneeing in front of her?”

“M-mistress.”

“So, do you think I’m pretty?”

“Yes Mistress.”

“Would you like your little sister and Mistress to fuck you?”

I dropped my eyes. I couldn’t answer that.

She grabbed me by the hair and jerked my head back so she could look into my eyes. “Answer me, slave.”

“Y-y-y-yes M-mistress.” I sobbed.

“Yes what?”

“Y-yes I’d-I’d like you to…to…fuck me.” I moaned.

“Mistress.” I quickly added.

“You’re a little fucking pervert to want to be dominated and raped by your thirteen year old sister.”

“I-I-I know Mistress.”

“Well! Lucky for you I’m a little pervert too! Looking at your sexy pictures gets my pussy so wet! It’s given me a lot of ideas and I‘m going to try them all out on you, big brother. How does that make you feel?”

I didn’t know how to answer.

“S-scared.”

She giggled. “Good. Now take off my panties.”

I only hesitated for a moment before reaching under my sister’s skirt and gripping the edges of her panties. I pulled them slowly down her sexy young legs and she stepped out of them. I hadn’t seen anything at all but now I was holding a pair of soft cotton panties in my hand and I knew there was nothing on under her skirt.

“Do you want to smell them, Stevie? They’re nice and wet.”

I hadn’t thought about it til just now but suddenly I was dying to sniff my sister’s worn panties.

“Yes Mistress.”

“Go ahead you little pervert.”

I lifted the panties to my face and sniffed hesitantly. Then I crammed them up under my nose and breathed deeply, savoring the earthy aroma of my sister’s sweet young pussy and feeling her pussy juices on my face.

“Do they smell good?”

“Oh yes Mistress!” I gasped.

“Well here comes the real thing!”

She swung one leg over my shoulder and roughly shoved my face straight into her wet pussy!

“Lick, slave! Lick your Mistress’s pussy!”

I started licking. I’d never done this before. Luckily Shannon had never done it either so she really didn’t expect much. She did order me to go faster several times. I couldn’t believe I was down on my knees servicing my dominant little sister’s luscious pussy! I was in heaven!

Finally she grabbed me by the hair and mashed my face against her pussy.

“Oh yes!! Fuck yes, Stevie!! Oh God!!!”

Her juices flowed down my throat and I swallowed all I could.

She let go of me and I fell to my hands and knees between her legs gasping.

“Oh that felt so fucking good!” She gasped.

I knelt there silently in front of my sister while she recovered from her orgasm.

Finally she asked. “Did you like eating my pussy, Stevie.”

“Yes Mistress!”

She nudged my dick with her foot. “Do you want to do something about that little thing, now?”

“Yes! Yes Mistress!”

She giggled. “Weeellll, maybe later tonight. We’ll see what kind of mood I’m in. For the time being no jerking off.”

I sighed. “Yes Mistress.”

I was dying to cum here!!

“And I put a password on all those naughty pictures on your computer. No more looking at them without my permission.” She turned and cleared the screen.

“Yes Mistress.”

“Now I think you need a spanking, big brother.” She sat down on the edge of the bed and patted her lap. “Come on. Over little sister’s knee.”

I crawled to her and lay across her lap. This was even more humiliating than eating her pussy. My hard dick was pressed against her leg. She squeezed my ass, digging her nails into it. Then she took her hand away.

I waited. Waited. For the inevitable-

*SMACK!!*

“How’s that feel, slave?”

*SMACK!!*

“Like being spanked by your little sister?”

*SMACK!!*

“I’m only thirteen, Stevie, and you’re a grown man!”

*SMACK!!*

“You’re pitiful.”
*SMACK!!*

Shannon continued to spank and humiliate me. It was really starting to hurt! Was she ever going to stop?? I squirmed around on her lap.

*SMACK!!*

“Don’t you move an inch til I’m done with you!”

*SMACK!!*

I don’t know how long she spanked me but it felt like forever. Finally she pushed me off her lap. I quickly got up on my knees again.

“Now thank me for disciplining you and kiss my shoes, slave.”
I leaned down and submissively kissed the toes of her sneakers.

“Thank you for disciplining me, Mistress!”

“Okay now listen up, slave. This is how it’s gonna be. Whenever mom’s not around you’re my slave. You are to call me ‘Mistress’ and you may not wear clothes. Tonight I’m coming back here to have some more fun with you after mom’s asleep. I want you waiting for me naked on top of the covers. And remember what I said: No jerking off without my permission.”

“Yes Mistress.”

“Now I’m going to get my homework. You’ll be doing it for me from now on.”

Mom came home and I ate dinner with her and Shannon acting as normal as I could. I was sure she could tell something was weird with me but obviously she could never guess what.

Shannon was fantastic. She acted no different than she ever had. I wondered if she’d punish me for my poor performance.

After dinner I went back to my room and finished her homework. When I was done I brought it to her room. I listened carefully. Mom was downstairs watching tv.

I got on my knees and knocked softly on the door. Shannon opened it and I held out the papers to her.

“Your homework, Mistress.”

She patted me on the head. “Good slave. Dismissed.”

I turned and crawled back down the hall to my room.

That night I lay on top of the covers naked waiting for Shannon. I didn’t jerk off but my dick was rock-hard in anticipation.

Where was she?? Maybe she’d just fallen asleep. Well, even if she had I would stay here naked all night long just as she had commanded.

Suddenly the door opened and my sadistic young sister slipped in. I immediately got off the bed and knelt before her.

She smacked me on the head. “I told you to stay on the bed, slave!”

“Sorry Mistress!” I scurried back up on the bed and lay back against the pillows.

She stepped up onto the bed and straddled my waist. She dropped some piece of cloth on the bed but my eyes were glued to her. She grabbed the hem of her nightgown and pulled it up over her head and for the first time I got a good look at my sister’s fantastic body.

Her breasts had developed wonderfully and I was sure they would just keep on growing. Her stomach was trim and her long legs looked sleek and strong. My mouth was practically watering.

“Like what you see, big brother?”

“Y-yes Mistress!”
She sat down on my stomach. I could feel the heat and moisture on her pussy against me.

She picked up that cloth off the bed and took my left hand and tied it tightly around my wrist. Then she reached up and started to tie my wrist to the bed post. Her luscious young breasts were just inches from my face. I was dying to suck and lick them!! I was trying to get up the courage to ask for permission when she leaned back and started on my right wrist.

When she was finished she ran her hands slowly down my chest. “I like you this way, slave. Completely helpless.”

She started to tickle my exposed armpits. I bit my lip and squirmed underneath her.

“I haven’t done this to you in a long time, have I, Stevie? It’s even more fun when you just have to lay there and take it.”

This was driving me crazy! I wanted to just buck my hips and get her off! But I knew I couldn’t do that. I just bit my lip harder and endured the torture silently.

She finally stopped and started touching her own body.

“Do you like my breasts, Stevie?” She said, squeezing them.

“Yes Mistress. Very much.”

She giggled. “I love how big they’re getting!” She leaned forward and thrust them in my face. “Kiss them.”

I eagerly started kissing my sister’s perky breasts. I started licking and sucking. They felt so good! So soft! And the taste of her skin was just incredible!

“Yeah! That’s right! Suck my nipples, big brother!” She gasped.

She shoved them further against my face, pressing my head against the headboard.

“Mmm, okay, okay.” She sighed, moving back and taking her gorgeous breasts out of my reach. “Very good, slave boy. Now to introduce you to your Mistress’s ass.”

She stood and turned around and my eyes were glued to her incredible ass. She crouched down and it bumped against my face. She leaned forward a bit so it was right in front of my face.

“Go on, you little slut. Kiss you Mistress’s ass.”

I eagerly leaned forward and started the deliciously humiliating chore of kissing my sister’s ass.

After a few minutes of kissing she thrust her ass back, pinning my head to the headboard and my face between her ass cheeks. I could barely breathe. She leaned back, putting most of her weight on me.

“I really love those face sitting videos, Stevie. I’m going to be using your face for a seat a lot! Would you like that, big brother? Of course it doesn’t mater if you would or not because you’re just my slave. Say that, Stevie. Say it into my ass.”

“I’m your slave.” I mumbled into her ass, gasping for whatever breath I could.

“Say ‘I’m my little sister’s slave and I worship her ass.’”

“I’m my little sister’s slave and I worship her ass.”

She took her ass away from my face and I gasped for breath. She turned around and sat down on my legs.

She took my cock in her hand and started sliding it up and down.

“Mistresssss…” I moaned.

She giggled. “You’ve got such a pretty cock here, Stevie. It’s pretty big too.”

“Thank you, Mistress.”

“Now I’m going to ride it. Time to deflower you, big brother!”

She moved forward and her hot, wet pussy rubbed against my dick.

“Ohhh, Sha-Mistress!” I gasped.

She grabbed my dick from behind and put the head into the swollen lips of her pussy.

“Mistress…I…I’ve heard it’s-it’s painful for a girl…to lose her virginity…on top. Maybe you should…I mean…”

She giggled. “Aw, so sweet of you to be concerned about your little sister.” She leaned forward and kissed me on the cheek. “Don’t worry. I popped my cherry a long time ago. Masturbating to the stuff on your computer. Now I’m ready to take my brother’s big, hot cock!”
With that she slid back and engulfed my entire cock in her hot, tight pussy.

“Oh fuck! You are sooooo big!” She gasped.

She started sliding slowly back and forth on it.

“Oh god that feels good, Mistress!”

Shannon started bouncing up and down on my cock. It felt incredible! Her breasts bouncing, her strong young legs flexing, I wanted to touch her so bad! It was so fucking frustrating!

She was in charge here. My sister. My Mistress. Fucking me. Raping me. And there wasn’t a damn thing I could do about it!

Suddenly Shannon slid all the way down on my cock and her pussy gripped is tightly.

“Oooohooooohhhhoooohhhhhhh” She moaned with her head thrown back.

She put her hands on my chest and leaned forward, looking down at me. Her eyes were slightly glazed.

“That was fucking incredible!! I’ve never felt anything that good in my life!!”

“Sh-M-Mistress!” I gasped. “Please. Let me cum!”

“Huh? Oh. Oh yeah. Well, since you’ve been such a good slave I guess I should let you cum too.”

She started slowly pumping up and down on my dick again. She gradually started to pick up speed again.

“Ohhh, it feels sooo good! I think I’m going to cum again!”

“Oh! I’m cumming too! God, thank you, Mistress!”

Her tight, incredible pussy clamped down on me again just as I started to spurt gallons of cum inside her.

“Oh thank you, thank you, Shannon!! Thank you so much for being my Mistress!! You’re all my dreams come true!!”

She slapped me.

“Shut the fuck up!” She hissed. “Mom will hear!”

I realized I’d been practically screaming. I clamped my mouth shut and just moaned as the most incredible orgasm of my life swept my entire body and my dick, imprisoned in my little sister’s tight, perfect pussy emptied it’s massive load.

“Ohhh that was unbelievable!” Shannon purred as she put her head on my chest and just lay there on top of me.

Within seconds I could tell she was asleep. I was exhausted. I wanted to close my eyes and sleep with my Mistress. But I knew if we both fell asleep we might very well sleep til morning. And then we’d both be in real trouble.

I lay there for a long time, letting her rest on top of me. Finally my eyes were closing. I couldn’t stay awake any longer. I had to do something.

I leaned forward and nudged the top of her head with my lips.

“Mistress. Mistress. Wake up. I’m sorry.”

“Hmm? Wha?”

She looked up at me and smiled. She wrapped her arms around me.

“Wasn’t that incredible, Stevie? Hmm?”

“Yes. Yes it was, Mistress. But now I think-Maybe you should-”

“Oh yeah. I guess the fun’s over for tonight, huh?”

She reached up and started untying my right wrist. She was sleepy and laying across me and her breasts were pressed against my face.

“Well don’t worry. I’ve got all kinds of things planned for my little slaveboy. Tonight was just the beginning.”

“Yes Mistress. I can‘t wait, Mistress.”

She sat up on the edge of the bed and yawned while I rubbed my aching wrists.

“I’m too tired to walk all the way to my room, Stevie. Get down on your hands and knees.”

I was exhausted too but of course I would do anything for Shannon. She sat down on my back and slipped one of the long pieces of cloth between my teeth. She held both ends like reigns and slapped them lightly against my shoulder.

“Okay. Go Stevie!”

I crawled to the door and she opened it. I crawled down the hall naked with my sister riding on my back and then into her room where she laid down on the bed.

“Oh hey, I forgot. Lick all your sticky cum out of me, slave.”

“Huh? Oh yes Mistress.”

I crawled up between her legs and eagerly started licking her sweet pussy. I’d seen guys perform this deliciously humiliating chore on the internet lots of times. I’d even tasted my own cum before. I didn’t like it but it wasn’t bad either. And mixed with the taste of my sister’s amazing pussy it was incredible. I stuck my tongue in as deep as I could, determined to clean up all my cum and satisfy my Mistress.

“Oh yeah that’s it, Stevie! Get in there deep! Get all your hot, wet cum! Oh that feels good! Lick faster!”

I licked until my sister’s body shuddered with yet another orgasm.

She reached down and petted my hair like I was a dog. “Good boy! That’ll be all for tonight.”

I stood up and pulled the covers over her. I tucked them around her and leaned down to kiss her cheek. She was already nearly asleep.

“Goodnight, Mistress.”

“Goodnight.”

I turned to go.

“Hey wait. Come back here. I almost forgot.”

I went quickly back to my Mistress.

“Hand me that cloth.” She pointed to the one that had been in my mouth. “Now turn around.”

She tied my hands firmly behind my back.

“Okay. You can go. I’ll untie you in the morning.”

“Um, Mistress…I…I have to pee…”

“Well then you’ll have to sit down like a girl. Go on. I’m fucking exhausted.”

I hung my head. “Yes Mistress.”

I walked to the bathroom naked with my hands tied behind my back and sat down to pee. Then I went back to my room, carefully opening and closing doors behind my back and lay down for a long night in bondage.

I woke up and was scared until I remembered that Shannon had tied my hands behind my back. I lay there thinking about the incredible night of domination with my dick sticking straight up. Of course I couldn’t touch it and even if my hands were free my Mistress had forbidden it.

Suddenly Shannon slipped into my room.

I stumbled quickly down to my knees.

“Good morning, Mistress.”

“How did you sleep, slave?”

“Not very well, Mistress.”

“Don’t worry. You’ll get used to sleeping in bondage eventually.”

“Yes Mistress.”

“Okay. I’ll take that off for you.”

She went behind me and leaned down to untie my hands. Then she immediately tied the long piece of cloth around my neck. She walked around in front of me, holding the other end of the cloth.

“Come, slave.”

She pulled me to the door on the make shift leash and listened carefully.

“Coast’s clear.”

She opened the door and dragged me out into the hall naked. She led me down the hall and into the bathroom. There she took the leash off me.

“Go ahead and pee if you need to. But sit down for cripes sake!”

I did even though it was incredibly embarrassing to pee in front of my sister.

“Okay now crawl into the tub.”

Shannon slipped her nightgown off over her head while I knelt there in the tub. Then she stepped in naked and straddled my fake with her pussy pressed against my lips. I waited anxiously for her to give the order to lick.

“Okay, now I have to pee. Open your mouth.:”

“What??”

“Open your mouth and swallow as much as you can, slave.” She snapped in her cold dominatrix voice.

I obediently opened my mouth and tried to prepare for the worst.

Hot urine flowed into my mouth. I gulped it down, trying not to think about what was happening. She must have been holding it all night! I drank most of it but some dripped down my face.

Finally she was finished. That wasn’t as bad as I thought.

“Lick me clean.”

I probed the folds of her pussy with my tongue for a moment then she stepped back.

“Now lick your lips. That was very good, Stevie. I‘m impressed.”

“Thank you, Mistress.”

“You were just born to be a slave weren’t you, Stevie?”

“Yes Mistress.”

“Did you like drinking my piss, slaveboy?”

“Yes Mistress.” I hadn’t liked the taste but the submission and humiliation had been incredible!

“Well that’s good since you’ll be doing it from now on. I expect you to get good enough that we can do it outside of the bathtub.”

“Yes Mistress.”

“Okay now let’s shower.”

She started the water and ordered me to wash her. I was in heaven intimately touching every inch of my sister’s fantastic young body. I washed her beautiful golden hair and then she told me to wash myself.

When I was soaping my dick she let me jerk off for a few minutes but stopped me before I came.

When I was done I dried my amazing, dominant sister’s hair and body she had me help her get dressed.

She pushed me up against the wall and squeezed my still hard dick.

“Okay, I’m going down to breakfast. Then you can get dressed and come down.

“I want you back here right after school, slave. I’m going to do sooo many things to you. Painful things. Humiliating things. Try to guess what they’ll be while you’re at school today.” She grinned evilly.

“Y-yes Mistress.”

She slapped me on the ass and walked to the door. She listened for a moment and then slipped into the hall.

I slowly started to get dress, already consumed with thoughts of what my sister was going to do to me tonight.

At one time i allowed her to tag me easily so i can go chase her. She wears this beautiful bikini and it show quite much for a teenage boy like me to get really horny but I really never saw my sister that way until I saw her completely naked.

While i was chasing her, she would be facing down in the water trying to swim away from me. Like I said before, she cannot swim worth a crap but she is a tough grappling girl to be messing with. When I tagged her, i tried to push her under the water. First thing that came to my mind at the time was to get away from her so she cannot tag me back. Well, she flipped around so fast that when i was pressing her down that i landed my hand on her tits and at the same time, i gave it a squeeze, which felt very nice and firm. Nothing else happened after that.

"Red" (she has red hair, so that is her nickname.) I called out her name to tell her that dinner was ready. By the way, my parents were at work and the other kids were at my grandmother's house. So my sister and I were in the house alone. She comes running down the hallway with just a long t-shirt that goes half way down her tender thighs. You could see her nipples poking out of the t-shirt. I felt a stir down in my swimming short, which dries out very fast in the room tempurature.

We ate dinner and the first thing out of her mouth, "bro, did you know that it felt good when you touch my boobies.?" The first thing i thought of saying was that it was an accident. But I chose to say, with a big grin across my face - "like it?" She smiled at me and winked at me like she knows what is going to happen next, but i was inexperience and i did not know anything about what to do with a girl.

We went into the living room and started watching a movie, but not a regular movie that teenagers watch. We just grabbed a case without looking at the title since our parents rented a stack of movies. It turns out to be a porn tape and the scene that was on the screen was so unbelievable. (Peter North was slamming his body up against some woman who was on all fours, big tits flopping around, and a huge cum splatter across her face in the next few moments.)

"Damn, I wish I could get fucked like that.", my sister exclaimed. And I looked down to her body and she already had two fingers inside of her pussy. You can see the juicies sticking to her fingers and was dripping out onto the couch.  Her left hand went awry while she was coming and it landed short of my very rock hard cock while we were watching a porno.

I asked her if she was cumming and she said she just had the most intense orgasm she has ever gotten and she would love to have another one, but she wants it in a certain way. (She was not a virgin at this time due to her ex boyfriend forcing himself onto her, but she accepted the pleasure at the end. I had figure she wanted to wait till she met the special man in her life, but it has already happened before anybody ever found out.)

Next thing i know i see on the screen was some guy getting a blowjob. but what happens next was so unreal. she stands in front of me and she takes off my swimming short and she takes off her tshirt but i noticed that she was not wearing any patients. (Did she do this on purpose?) She jumps up and lands on my hips. But my dick slid right on her her clit and I could feel her warmth and her wetness. Then she tries to make herself comfortable and at this time, i slid right into her juicy wet pussy.

At the same time, she gasped and I gasped. She said, OMG! you are filling me up. You are bigger than my ex boyfriend. He is such a pencil dick. (I only went in once and stayed in the same position for about 20 seconds.)

She hops off of me and took one look at my glistening cock and she dove right for it, taking it in her mouth and starting carressing my 7 inch cock which is one inch thick. She did this for a while and she has already had an orgasm, but I have not had one yet.

I asked my sister if she was having some fun. Next thing i saw was that her pussy was right in my face as she stands up and I am sitting on the couch. I just grabbed her ass, which is plump and nice and I gave it a squeezing that it never felt before. I shoved my tongue on her clit and I sucked and licked and poked my tongue onto her clit. She grabbed my hair and shoved my face into her pussy as she proped one leg onto my shoulder. She was moaning and groaning like crazy.

I laid back and she straddled me again only this time, facing away from me. I grabbed her hips and I begin to thrust myself into her pussy. Now i am filling her up and going so deep inside of her that she almost passed out falling back on me. But I pulled her down and had her lay her back on my chest, so i can feel her tender tits, and squeeze her nipples till they are red. I rolled her on to her side as i turn my body and I begin to have sex wtih her.

Since she is so active, she moves around alot and she cannot stay in one position too long, so she got on all fours and i got up behind her. I pounded her pussy for a long time, but I held myself back knowing that if i cum, that it would be over soon. But i realized that we cannot do this forever since our parents come home in about a hour.

So i asked my sister if she was getting ready to cum. She said that she only wants to cum on her back with me inside of her. so i told her to lay on her back and get ready for the ride of her life.

She laid on her back with her legs up in the air. I positioned myself to where i would have easy access to her pussy. As my head gets ready to enter her, she moved so fast that her mouth was on my dick in an instant second. She gave me to best head and came up to me and i held her up to me and slid her pussy right on top of my shaft.

As i enter her, she moaned and asked me to give her the fucking of her life like the first woman got when we first watched the porn.

I rode her, I pounded her, I felt like that my dick and my balls would fall off if i keep fucking her the way i was fucking her. She moaned and groaned and dug her nails into my ass, as she was on the verge of cumming all over my cock.

"I am getting ready to cum, bro. Fuck me, bro. Just fuck me."

"Sis?" I asked, "Where do you want me to cum? Inside of you, on your face, on your chest, or on your pussy lips? I am getting ready to cum."

My sister did not reply. She shot her cum all over my cock and feeling that send me over the edge. So as I tried to pull out, her nails dug in deeper to my ass, and i was not able to get out. When she used her legs to keep me inside of her, pushing me forward and deeper into her juicy pussy, I had to let go.

I cummed and cummed, shooting sperts of cum deep inside of my sister's pussy. and she was cumming along with me.

We laid there with me inside of my sister for about 10 minutes. As I pulled out, my cum and her cum starting dripping out. She grabbed my cock and pulled it towards her mouth and she cleaned me up by licking it clean.

As i pulled my shorts on and my sister grabs her shirt from the floor and used it to wipe the cum off the couch, my parent's car was just pulling in the driveway. Now we can tell that it was our parent's car because there was a big hole in the muffler. I ran towards the pool and she ran towords to the bathroom down the hall.

I jumped in the pool, realizing that we left the porn in the dvd. so i jumped back out and ran back in the house. My sister was standing there naked putting the dvd in the case and putting a different movie in. so i ran back out and she ran back upstairs.

As i was jumping in the pool, i noticed my cock was hard. and my sister was looking out the bathroom window, naked. I got out and was greeted by my parents using the towel to cover up myself, so they do not see me with an erection.

I walked over to the bathroom window and stuck my finger in my sister's pussy and a big glob of cum was on my finger. I licked it clean and I walked in the house, pretending to wait for my sister to get out of the shower but really what was going on is that i was going to to in there and fuck my sister one more time.

My parents were in the shower themselves and we could hear moanig and groaning coming thru the thin walls. So I sneaked up behind my sister in the shower and I inserted my cock inside of her and i fucked her once more and both of us cummed at the same time.

We rinsed off really quick and got out of the bathroom and went our own separate ways. We just hang out more and more, but nothing happens after that. Just a one time thing, so we thought.

More to come later, with different things happening.
