"What?"

   Dean was sitting there, holding onto his cock as if he was shielding it from some unknown danger.

   "I heard something. You sure your parents are away until tomorrow?"

   It's nothing," I said, resuming my wanking over the slut on the screen as she took a hard cock up her ass and pussy at the same time.

   Suddenly the door opened and my sister and my cousin literally fell into the room. Dean tried to tuck his cock into his pants but it was too hard to conceal. I froze with my hand on my cock and could only think of how my sister was going to make me pay for this moment for the rest of my life.

   Jessica and Stephanie began to laugh at the sight of us. "What the fuck are you two pervs doing!?" Jess howled. I tried with difficulty to tuck myself away, feeling red with embarressment. "You two haven't been makin' out, have you?"

   "Oh shit, they're watching your dad's movies," exclaimed Steph.

   I looked over at Dean. He had the same look on his face as me.

   "Is this the one where she gets the two cocks in her ass?" asked Jess, suddenly forgetting our predicament and focusing on the TV. She sat herself down next to me. "Remember when we watched this one, Steph."

   "Oh yeah," said Steph. "Johhny and Al fucked the shit out of us afterwards." She sat down between my sister and her brother.

   Jessica looked at me almost tenderly for a change. "It's OK, keep going. I don't mind." She looked back to the TV and moved a hand between her legs. I didn't know what to do. I thought it must be a trick so she could make fun of me again. But she slid her panties off and put her hand back under her skirt and opened her legs, playing with her pussy.

   I looked over and Steph was doing the same. Dean had his cock out again and was slowly starting to pump himself.

   "It's OK," said Jess, "don't be shy. I've never seen it hard before."

   I let my cock free and it poked high and proud.

   "Stroke it. For me." asked Jess.

   God! I was tingling all over. I knew my sister and my cousin were just drunk from the party. I was worried how this was going to go down in the morning. I knew that jacking off in front of my sister was way over the limits and I shouldn't be doing it. But she was hot and sexy and even though she was my sister, I'd often fantasized about her. Hell, I'd even peeked at her when she was getting dressed. But as i began to stroke my cock in front of here I was overcome by feelings I'd never experienced before.

   Jess started to make little moaning sounds as her hand moved quickly under her skirt. She was 21 now and very experienced, so I had heard. She had a killer body and dark brown hair to the middle of her back, and the most beautiful deep brown eyes. She looked at my cock as I played with it. She reached over and took my other hand and guided it down between her legs. My hand was shaking. It found heat and wetness as she placed it over her pussy. She smiled at me. "That's it," she said softly. I slid a tentative finger inside the warmth and she shuddered. She pushed my hand harder between her legs. "That's good," she said.

   With her other hand, my sister took over on my cock. She placed her soft fingers around the shaft and expertly began to slide her fist up and down. Dean let out a cry and we looked over to see Stephanie with her head moving slowly in her brother's lap. I looked back to Jess, my stomach tightening and butterflies going crazy inside my stomach. She looked into my eyes and smiled as she played with my hard cock. "You've always been cute," she giggled. She leant in and kissed me, pushing her tongue far into my mouth. It was the first time I'd ever kissed a girl. "Is this allright for you?" she asked. I nodded. "Me and Steph have talked about this for a while. I think Dean's enjoying it, too."

   I slid two wet fingers in and out of Jessica's tight hole. She let go of my cock and took off her jacket and pulled up her white singlet, showing me her beautifully shaped tits. She took hold of my cock again and lowered herself so that her nipples just grazed the tip of the head. She let her breasts hang down over my cock as it brushed her warm smooth flesh between them. She ran her beautiful breasts along my cock, sliding it between them, looking up at me and smiling. She stopped and looked over at Steph and Dean. Steph was kneeling before Dean and was taking his cock into her mouth. Jess moved down between my legs and spread them wide, smiling deviously. She rubbed the head of my cock gently over her chin, around her mouth, along her cheek, all over her pretty face. She licked her lips, teasing, slowly stroking me.

   "What do you think, little brother? There's no going back from this."

   I wanted it so bad. I didn't care what consequences came. I looked into my sister's eyes as she opened her mouth and took my hard cock inside it. She wrapped her lips halfway down the shaft. It was hot and wet and soft inside her mouth and it felt so good. She kept her eye contact as she slowly slid her lips back up. Her head moved down and she took more of my cock into her mouth, then sucked it back up to the head. She ran her tongue around the head and licked me down to the base of the shaft. "You like your big sister sucking your nice hard cock?" she asked.

   "Oh yeah," I moaned. She took it into her mouth again and began to suck me slowly, up and down.

   Dean and I looked over at each other as we got blown by our sisters.

   Jessica took my cock out of her mouth. "Let's go upstairs to mum and dad's bed. There's more room."

   My sister led me and Dean's sister led him upstairs to my parents room.

   The girls lay us down on the bed and started to take off the remainder of their clothes. Dean and I stripped. We were going to get to fuck our sisters.

   The girls crawled seductively up the bed towards us, smiling and laughing at each other. "You are both about to lose your virginity, you know that don't you?" asked Steph with a naughty grin. She climbed onto her brother and Jessica onto me. Jess kissed me with a desperation I'd never seen. She took hold of my cock and stroked it, rubbing it against the heat of her pussy.

   "I want you to fuck me so badly," she gasped into my ear. Her pussy was on fire as she rubbed my cock head against it, getting it wet.

   She rolled onto her back and spread her legs underneath me. I moved above her and she guided my cock against her burning hole. "Fuck me," she cried, looking up at me. I lowered myself down onto my sister and my penis slid inside of her.

"Oh yeah!" cried Jess as I entered her. She held me tight to her and kissed me. I moved my hips back and pushed into her again. I couldn't believe how good it felt inside, how hot and wet and soft, and I wondered if it would have been as good if I was not fucking my sister. I pushed into her again and slid it inside her as far as it could.

   Jess pulled my hips into her and I looked down on her and flicked my tongue against hers. I looked down to see my cock entering between her legs and disappearing then reappearing. We looked over to our cousins and saw Dean on top of Steph pounding away. They looked over to us and we laughed as we fucked.

   "I always thought our sisters were bitches," laughed Dean as he frantically fucked his sister.

   "Me too," I smirked.

   Jessica stopped moving underneath me and held me suddenly still. She looked up at me all serious. Oh shit! I thought. She can't stop now.

   "I'm sorry," I said.

   A smile broke out over her beautiful face. "I'm just kidding," she laughed. "You think I'd take you this far and then stop. I want you all the way. I wanna feel you shoot your hot cum inside of me."

   She moved her hips against me and I felt my cock slide inside her again. Oh, fuck, it felt so good. Jess rose her hips with every thrust of mine. Our sweating skin slapped together as I glided in and out of her. I wanted to cum so badly. I kissed her, our tongues sliding over each other. I entered her burning hole again and again, faster and faster. Jess started to groan, as did Steph and Dean beside us. I was fucking my sister. Fucking my big, sexy, beautiful sister. I looked down as I pumped away and Jess looked up into my eyes. She was so hot. I fucked her harder and harder and she held me to her. I felt I was about to explode everywhere. My cock slid inside my sister's burning wet pussy one last time and my cum started to spurt out inside of her. "Oh yeah!" she screamed. "Oh fuck yeah!" I pushed as far up inside of her as I could and shot another huge spurt inside her. She kissed me frantically, pulling me deeper inside. I kept shooting hot cum up into her. It was so fucking good.

   We lay there together, holding each other. Steph and Dean were finished next to us and doing the same. Jess kissed me again.

   "So, how was fucking your little brother," Steph asked.

   "Mmmmm," cooed Jess, looking up at me. "He did pretty good." I smiled. "For a first time."

   My big sister held me and looked into my eyes, and kissed me again.

   She began to stir and turned her head groggily to face me. "Morning, little brother," she smiled.

   I continued to pump away. "Morning, sis."

   Jess moved a hand behind and took my cock. She began to stroke it. I quivered with her touch, continuing to squeeze her breast and pinch her erect nipple.

   "Mmmmm," she groaned as she stroked me. "I've never known anyone to get as hard as you." She squeezed on my cock.

   I traced my other hand down between her legs and found her already wet. I slipped a finger inside of her and she gasped.

   "This is the best way to wake up," she smiled.

   She continued to play with my stiff cock and I explored the inside of her vagina with my fingers. She started to groan and to stroke me quicker. I pushed my fingers in deeper and she pushed against my hand with her hips. I squeezed her hard nipple and rubbed it firlmly between my fingers. She groaned louder and pushed against me harder. Finally her body bucked and she squeezed my cock tight. Her pussy squeezed around my fingers and she let out a desperate gasp, then her body slumped back against me.

   "Oh, god!" she said, breathing hard. "Oh, fuck! I need to wake up this way every morning!"

   Jess rolled over and on top of me, smiling again in her wicked way. My stiff cock was underneath her hot, wet pussy and she slowly began to grind it against me. She kissed me and I felt her tongue in my mouth. Her wet pussy lips slid along the length of my cock. She ground her pelvis against mine. She pushed herself up with her hands above me, grinning at me as she slid her hot pussy up and down along the shaft of my cock. I wanted so much to get it inside of her.

   "Oh, little brother," she teased. "I'm gonna fuck you so good."

   I tried to move underneath her so my cock could enter her. She pushed me down on the bed and waved a finger in front of my face.

   "Uh, uh, uh!" she taunted. Her pussy lips pushed down against my cock, hot and wet and teasing. She slowly trailed her pussy up along my cock then back. She leaned over me and pushed her breasts into my face. I kissed her full perfect breasts and took each erect nipple in turn into my mouth, sucking and flicking each with my tongue. I rubbed my hands over her back down to her firm butt cheeks, trying to pull her up a little so I could slide my aching cock inside of her.

   Jess moved her body down along mine and first kissed my neck, then each of my nipples. She ran her tongue down along my smooth bare chest down towards my cock. She took me in her hand again and started to slowly storke my with her magical touch. She licked my inner thigh and traced her tongue down under my balls and flicked her tongue against the sensetive skin. Her tongue made it's way up over my balls and she kissed them and bathed them with her tongue. She looked at me and smiled wickedly again as she sucked my left ball into her mouth. Her hand slid up the shaft of my cock as she rubbed it softly. She took my other ball into her mouth and sucked on it firlmy. Her tongue then traced it's way up to the base of my cock and ran slowly up my cock to the head.

   I looked down at my sister as she took my hard cock into her mouth. "Oh God!" I cried.

   She looked deeply into my eyes as she sucked my cock back up to the head. She grinned as her tongue swirled around it and she licked the tip of her tongue into the eye. She took my cock back into her mouth and took it all the way down to the base. She sucked it slowly all the way back up then let it out of her mouth. She moved back up over me until her pussy was again above my cock. She took my cock and pointed it up and let herself down as I slid inside of her.

   "Oh yeah, fuck me little brother," Jess cried as she rode me. It felt even better than last night and I knew I couldn't hold on long before cumming.

   Jess suddenly stopped as we both heard voices from downstairs.

   "Oh, Shit! It's mom and dad!"

   "But they're supposed to be away until this afternoon!" I said.

   We could hear footsteps coming up the stairs.

   "Quick, hide!" said Jess.

   I ran to the ensuite bathroom and closed the door just as mom and dad entered the room. Jess just had time to cover herself with the sheets and close her eyes as if she was sleeping. "Oh, hi," she said. "Weren't you supposed to be back later?"

   "We got up early and decided to come home," mom explained.

   "You kids have fun last night?" asked dad.

   "Yeah," said Jess with a grin. "We sure did."

   "Your cousins are downstairs having breakfast," explained mom. "Where's your brother? He's not in his room."

   "I'm in here," I yelled. "The downstairs bathroom was occupied and I really had to go."

   "Oh, OK," said mom. "We'll see you two downstairs for breakfast then."

   Mom and dad left the room and I came out with my roaring hard-on.

   "Oh, you poor thing!" Jess sat up int the bed. Seeing her naked made it worse. "The first chance we get," she said, giving the head of my cock a little kiss, "we can finish what we started."

   We got dressed and went downstairs. Mom and dad were thankfully oblivious to the knowing looks and smiles Jess, Steph, Dean and I were giving each other over breakfast. Mom and dad bored us with the details of their anniversary dinner and one or both of them seemed always to be following me or Jess around talking to us all day and we couldn't get a chance to slip off and fuck each other, as we were both desperate to do. So I had to watch my sister slinking around all day in her tight white singlet and her short denim skirt. I was going nuts.

   Mom and dad put on the usual sunday afternoon barbeque and Dean and Steph stuck around. The four of us finally got away from my parents and sat in the backyard while they cooked. We discussed the night before and how great it was.

   "You two were fucking this morning when your parents got home, weren't you?" asked Steph.

   "We were trying to," giggled Jess.

   "We heard them driving in and got downstairs straight away," added Dean.

   "We didn't get to finish, though," said Jess, giving me a sorrowed look. "I think my little brother here is having a little trouble getting through the day." Jess put her hand on my leg and gave a squeeze. She looked over her shoulder at mom and dad, who had their backs to us, cooking. She leaned in to me and kissed my passionately, our tongues meeting, and she put her hand on my cock and rubbed it. She broke our kiss just before mom turned around to tell us lunch was ready.

   "I don't think he'll be able to stand up for a while," laughed Steph, as they got up to get lunch, leaving me sitting there with my hard-on, watching my sister's ass as she walked away.

   After lunch, we were all sitting and talking in the living room. Jess offered to wash up, a first for her. She said she and I should wash up because it was mom and dad's anniversary.

   "Don't worry," said Steph, giving me a wink. "We'll keep your mom and dad busy."

   Jess and I left the room quickly and went into the kitchen. She grabbed me and kissed me desperately. I pulled up her shirt and took her breasts into my hands. She looked around, making sure mom and dad couldn't see us from the living room. She unzipped my pants and took my aching cock out. I reached down and pulled her panties down and pulled up her skirt. She spread her legs a little and I pushed her back onto the kitchen counter. She guided my stiff cock against her pussy lips and I easily entered between them. Jess was burning hot and she hugged me and kissed me as I pulled my cock almost out of her and slid it all the way back inside. I kissed her breasts and her neck as I thrust desperately into her. It felt so good to finally have my cock back inside my sister's pussy. I fucked her harder and harder, she let out loud gsaps and tried not to scream out. "Oh, yeah, fuck me!" she whispered into my ear. I looked down and saw my cock disappearing between her legs and I looked into her beautiful face and her big brown eyes and I kissed her and forced my tongue into her mouth and I fucked my sister harder, then, with a final shove, I came inside of her. "Oh, Fuck!" she whispered. "Oh, yeah, oh yeah, cum inside me little brother." I pushed again and shot my cum deep inside of her again and again. She held onto me and we kissed again. I finally finished coming inside of her and we held each other tight. We were both panting and swweating and I slowly slid myself out from between her legs.

   Jess held my face with her hands. "That was so good, little brother. You're the best fuck I've ever had."

  We kissed again. I felt a relief like nothing else I'd known.

   "How's the washing up going?" came mom's loud voice just metres away from us.

   "Really, really good," said Jess, still trying to catch her breath.

   As Jess pulled up her panties and I pulled up my pants, we arranged a time when I could come into her bedroom that night, when mom and dad would be asleep.

   "For the first time in my life," said Jess, smiling her wicked smile, "it's gonna be really good the two of us living under the same roof."

   We washed up, straightened up, and went back to the living room   Â
