It all started innocently enough. Back when I was 14 and my little sister Sara was 13, we were watching cable TV. I can’t remember what it was we were watching, but there was a nude scene, and without me realizing it, I tented my sweatpants with an erection. I didn’t know about it until my sister said, “Eww, that’s gross!” I looked at her, and then followed her gaze to my crotch. I must’ve turned beet red because I felt my face get really hot. I’ve always had a problem with not being able to tell if I had an erection or not, unless I intentionally wanted one. I took the throw pillow and covered myself and once it went away, I got up and left. Embarrassingly enough as it used to be when I’d go to the swimming pool and have an erection (thank god it was while I was in the water, most of the time), but this was in front of my sister.

Â

Sara said that she didn’t start to develop into a woman until she was almost 14, whereas I started growing pubs at about 12. When that happened, I had a difficult time facing my sister, or any woman for that matter. It wasn’t until I was 16 when we had our first close and intimate conversation about dating and stuff about the opposite sex. Sooner or later she asked me if I were still a virgin, which I was, and I found out that she was one as well. We started talking about the different people that we’d each like to date, and at some point she admitted that she’s never even seen a guy naked before (well, not since we were kids taking baths at the same time). We sparked up conversations like this throughout the year, getting bolder as we went on.

Â

As far as what we’d wear around the house, at first, it was conservative clothes all of the time. Eventually, I’d roam the upstairs in just my boxers, and she would sometimes come out of the bathroom with just panties and a bra or a long t-shirt, but usually would wear shorts and a shirt when we went downstairs. Some of our conversations would be in my room just sitting on my bed in our underwear watching TV, or in her room lying in her bed having really long talks.

Â

Through a very intimate conversation, I admitted that I had a deep fascination with the vagina as she rolled her eyes at me. I told her that I just can’t seem to understand it, what it looks like, its different parts and functions. Apparently, she had the same fascination about erections, and surprisingly, even her own vagina. She told me in the deepest secret that she and her best friend would sometime looked into mirrors at themselves and at each other, and even went so far as to touch each other in experimentation. She also had said that she even practiced kissing and caressing with her. That did it for me. I got a major hard-on which tented the sweat-shorts that I was wearing.

Â

“Whoa, Tiger, don’t bust a vessel on my account,” she said as she giggled and pointed to my tenting sweat shorts.

Â

“Sorry, it’s just that when you said that you kissed another girl, I guess it just got me…you know, excited,” I tried to explain in honesty as I reached for something to cover my lap with. “Perhaps we shouldn’t talk about stuff like that,” I lied.

Â

“Yeah, I don’t think that would go over well with mom and dad if they found out that you got a hard-on while talking to me. It’s a good thing that they’re gone for the evening.”

Â

“It must be difficult for a guy, in the way that if he gets excited, he can’t hide it,” she stated matter-of-fact like staring out into the distance. “For a girl, we just have to be sure to wear thick shirts. Even then, we can blame the temperature if the setting is right. But if a girl gets too excited and wet, then it can be…well you know.”

Â

This got me curious, “What do you mean?”

Â

“Well, you know that when a woman gets excited, she gets wet between her legs, right?”

Â

“No, I didn’t know that.” I had actually heard that, but I just didn’t believe it coming from a guy in my gym class.

Â

“Yeah, when a woman gets sexually excited, she’s get wet in anticipation of a man’s erection. And this moisture can seep through her clothes.”

Â

“Has that ever happened to you?”

Â

“Uh, well I suppose, yeah. Sure…” I could tell that Sara wanted to say more, but she just bit her lip in that cute girl way and smiled at me sheepishly.

Â

“What? I know you want to say something. What is it?”

Â

“Well, what would you say if I were to tell you that I’m a little wet right now?”

Â

I just about blew my load then. Here’s my little sister telling me that basically she’s just as horny as I am right now. I started squirming in my seat. My breathing became erratic, and I had a difficult time making contact with her sparkling blue eyes. My mind was bellowing with thoughts of her panties getting soaked; it was getting very difficult to keep myself from pulling my erection out in front of her.

Â

“Do you need to do something about that,” she asked while pointing at my covered lap? “It doesn’t look like it’s all that comfortable. Do you need to shift it or something?”

Â

“Actually, I should just go into the bathroom and ‘take care of it’. But it’s embarrassing knowing that you know what I’m gonna do.”

Â

“That’s another reason why I think that it must be difficult for a guy. A girl can move in just the right way, and she’s ‘taken care of’ for the moment.” She shifted her hips a few times and inhaled deeply. “Ahh! Just like that.”

Â

“You just had an orgasm, just from moving in your seat, and in front of me!?” I couldn’t believe her, and it was really getting to me.

Â

“Yeah, but it was only a very small one. I can get kinda wild when I have a large orgasm.”

Â

After she said that I noticed her nipples poking through her t-shirt nightgown. She must’ve caught me gawking at them when she asked, “Have you ever seen a naked girl live before?”

Â

“No Sorry, I didn’t mean to stare. It’s just, I’ve got this thing in my pants, and it doesn’t seem to bother you that I have an erection, and you being so open about it all... well, it just is getting to me.” Then she did something totally unbelievable. She took her nightgown off.

Â

“Well, now you have.”

Â

I gulped. Then I gulped again. My eyes were glued to her breasts, which at a size B I guess, were the most beautiful sights I’ve ever come across. I stared for a few moments, and then let my gaze wander to her crotch. She was right, when a woman gets excited, she gets wet.

Â

“You know, you don’t have to go ‘take care of it’ in the bathroom, if you don’t want to.”

Â

“What? Do it here in front of you????”

Â

“Well, I’m not embarrassed about you doing it in front of me. I mean, we both know that you ‘need’ to, and we’ll both know if you go to the bathroom to do it. Besides, I’ve never seen a guy’s thing before. I’ve shown you mine, I think that it only be fair if you show me yours.” Then she did something else to get my mind reeling, she opened her legs even farther apart. “As you can see, I need it too. God I’m so horny just knowing that you are sporting a hard-on from our conversation.” She leaned back against the arm of the sofa and pulled her left leg up onto the middle cushion, stretching her chest out giving me a complete showing of her breasts. Her arms kept going backwards, and she grabbed the bottle of lotion off of the end-table. “Here, I’ve been told this helps,” she said as she tossed the lotion to me.

Â

With my jaw feeling like it might fall off, I just sat and stared at her marvelous body as she softly brought her fingers to just under her left breast, her other hand following in the same fashion to her other breast. I could see her nipples stiffen even more while she stroked the undersides. “Mhmm,” she let out and she closed her eyes, tilting her head back further. Her index finger and thumb met at the apex of her nipples as she pinched them just slightly. I slowly leaned back onto the opposite arm rest of the sofa and brought my right leg up onto the cushion.

Â

She opened her eyes with this strange look, searing into mine. With a slight struggle in her voice, “Aren’t you going to join me? At least take that pillow out of the way.” Her left hand started to head towards her panties, which were definitely soaked and looked really shear. I could make out her pubic hairs, and the folds of her lips where pressing the material into her crevice. When her hand got to the elastic waist band, they just lingered there as her other hand was going back and forth between her breasts. Slowly her left hand slipped past the waist band and I guess made its way to her vagina because she took in a deep breath and cooed an exhale. She stared back at me with a look that kinda reminded me that she might be upset, hungry, and desperate all at the same time.

Â

Frustratingly, she growled at me, then got up off of the sofa and in a flash, took her panties off. But before I could take a good look at her goods, she reached to my lap and took the pillow away. Then she said, “Stand up!” like she was a mad woman. Begrudgingly I obeyed. When I got to my feet, she grabbed my shorts and underwear, and in one motion yanked them to my knees, not taking care that my hard-on got caught in the waist bands. When my erection sprang free, it whacked her on the face. At first, I thought that she was disgusted with the act of my erection coming into contact with her face, but she just sat there on her knees with her hands on my shorts, which were still around my calves, and her eyes glued to my bobbing hard-on.

Â

“Does it hurt,” she asked with a gleam in her eye, and a wicked grin?

Â

“Kinda, but mostly because…well, you know.” Everything was still in that shock and awe stage between us. As a matter of fact, I had to concentrate really hard to remember each detail; I’ve even had to persuade my sister to help me write this. We’ve spoken of many things between us, but none of our conversations included personal sexuality until that day.

Â

Still staring at my engorged penis, Sara breathes heavily. Twitching just inches from her mouth, I feel her hot breath on it.

Â

“Will you show me,” she begs? “Will you show me what it looks like when you cum?”

Â

For the first time in our young lives, I heard my sister say a word that couldn’t be spoken in front of anyone with the likes of our parents. As I registered her request, my erection twitched hard again, and more pre-cum leaked from its tip. I looked past the head, and a bit farther than her hard pointed breasts, and took notice that her hand was busy rubbing herself. That, mysteriously, was all that I needed, and a spurt of semen escaped me forcefully across the air, and onto her chin. She reflexively jerked backwards as another volley landed on her neck, and the next on her chest close to her left breast where her hand was busy pinching her nipple, and yet more squirted out onto her….volley after volley landed on her in the most exotic, erotic and beautiful fashion than I could ever imagine.

Â

Through my half closed eyes, which were straining to maintain control against being pushed into the back of my head, I noticed that her hips started to buck against her hand wildly. Then I heard her start off with a very low moan that escaladed into a high pitched scream all the while she kept falling backwards towards the television. When her back hit the floor, she raised her hips high into the air and humped her hand while screaming words that I never knew that she knew.

Â

“HOLY SHIT!! HOLY SHIT!! FUCK!! HOLY SHIT!! GAWWDDDD!!!! I’M CUMMING JOHN, I’M CUMMING SO HARD. FUCK!!!!” She kept yelling over and over as her head slammed from side to side. She had to brace her head with her arm to keep it from slamming the floor too hard. “I’M CUMMING!! I’M CUMMING!! *large inhaling breath* I’M CUMMING!! I’M CUMMING! I’M Cumming! I’m Cumming! I’m cumming.”

Â

During all of this, she kept humping her hips higher and higher into the air; all the while I kept squirting my semen onto her. She even raised her hips high enough to have the back of her wildly rubbing hand touch my testicles. Soon her wild and loud screaming started to wane off, and then something happened that I never even knew was possible, she started squirting a stream of liquid from her vagina directly at my middle thigh. We both later found out that it was ejaculation; something of which we were both new to, as it came from a woman.

Â

As her hips started to return to the floor, I realized that I was holding my breath. Exhaling with a huge grunt, I started to waiver a bit because of my legs feeling like they were giving out. I fell to my knees in front of her, and braced myself against the middle cushion of the sofa behind me. Unbelievably, I just stared in complete awe at her while our breaths were returning to normal. She continued to rub herself and pinch her nipples, but with more grace than anything else.

Â

When she finally opened her eyes, she sheepishly involuntarily pulled her knees together, which were blocked by my body.

Â

“Holy Fuck that was awesome. Never in my life had I ever experienced such a powerful orgasm,” she breathed heavily.

Â

When I could finally muster up enough strength and courage, I spoke at last, “I never experienced that before!”

Â

“What, doing it in front of a girl?”

Â

“No…well that too. But I’ve never experienced and orgasm….without touching myself.”

Â

“Oh yeah, that’s right. I was just too busy to notice. Don’t guys normally have to ‘wank’ or ‘jerk’ it for a while before they cum?”

Â

“I still can’t get used to you saying the word ‘cum’. And yeah, every time that I do it, I have to stroke at it for like a half hour before I cum; and even then, I’ve never cum that much before.”

Â

“Cum. Fuck. Shit. Pussy. Cock. Blowjob. Fuck me in the ass now damn it. Screw my brains out!! – How do those words work for you coming from your younger sister?”

Â

Somehow, hearing those words, she was breathing new life to my still hard penis. She took notice to this as well as she peered down the length of her body, past her hand which was still softly rubbing her. “Aren’t you supposed to go soft after you ejaculate or something?”

Â

“Yeah, another new thing to me – that’s never happened before.” I tried to think of something intellectual to say, but all that was happening was me staring at her smearing my cum around her breasts. Then, as though it were just an experimental thing to do, she scooped up a small amount on her fingers, and brought it to her mouth. Letting it dangle like a noodle, she let it drip onto her tongue. God that was such an exquisite site to my eyes, I could almost feel the need to cum again.

Â

More to cum….
