MORE sl**p OVER FUN SeXStoRY

Two weeks had past since my s****rs last slumber party. Tonight she was having just one of her friends sl**p over with her. Gina wasn't able to make it to the previous slumber party and I had never seen her before. She was a very pretty girl with reddish brown hair, a slim build with great legs. The thing I really liked most about her were her were her fantastic full round tits that must have been 36C's, they looked like two gr**efruits perched under her top. When she first arrived she was wearing cut-off jeans and a tee-shirt that fit snugly across her chest. Later after they had changed into thier nighties I was able to get a much better look at her when they came into the kitchen for some snacks. I told them there was a good movie on TV and they joined me in the living room to watch. We sat munching chips as we watched the movie. Every now and then I would glance over at Gina sitting in the chair across from me gazing at those long legs and her sweet breasts perched under her thin pink nighty. I was getting pretty horny by the time the movie ended. They got up and went to my s****rs room. I watched as Gina walked out, her firm breasts bounced a little under her nighty. As she walked past me the light from the lamp behind her shown through the thin material silouetting her tits. My cock began to stiffen and after they were gone I started rubbing my boner in my pants as I sat on the sofa for a while. Thinking they must be asl**p by now I unzipped my pants and pulled out my cock and began to masturbate slowly as I thought about Gina's tits and the fun time I had two weeks earlier during the slumber party. I was enjoying playing with myself, stretched out on the sofa, my eyes closed stroking nice and slow on my throbbing hard cock. A few minutes later my s****r and Gina walk in, "See Gina, I was right. I told you he was probably jerking off." My eyes popped open when I heard her voice. A rush of excitement shot through me as they walk closer to me. Gina said "You told me he had a nice cock but I didn't think it would be so big." I looked up at her, she was licking her lips and smiling. "Would you like to help me Gina?" I asked. She sat on the edge of the sofa next to me. "Let's start by getting these pants off." she said as she loosened my belt and unsnapped my jeans. My s****r helped as they pulled them off then removed my underware. My rigid cock stood up as Gina put her hand around it sliding up and down the length of my shaft. I reached out slipping my hand under her nighty feeling her beautiful firm breasts squeezing them as she played with my throbbing cock. "Why don't you girls get naked too and we can have some real fun." I said. Without hesitation they took off thier nighties. I said "Panties too please, I want to see your pussies as well." They pulled off thier panties and stood there for a moment as I looked them over. I had never seen my s****r completely naked before, she had just a small patch of blonde hair between her legs. I ran my fingers over the soft curly pubes. Gina on the other hand had much more, thick dark red fur covered her mound. It was soft to the touch as I played running my fingers through her pubes and around the tender lips of her pussy. I teased with her as I probed my finger gently inside her warm moist hole. My cock grew harder aching to be inside her. They got on thier knees beside me and resumed playing with me, my s****r fondled my balls while Gina had my cock in her hand rubbing the head. She leaned over putting her soft moist lips over the tip and sank her mouth slowly down as far as she could go nearly taking all 7" of me. It was obvious this wasn't the first time she had sucked a cock as she skillfully worked up and down, licking and sucking like a pro. Once she had my cock nice and wet she sat up and wrapped her gorgeous tits around me sliding them up and down as she squeezed them tight on my dick. It felt fantastic as she titty fucked me for several intense minutes. I told my s****r to get a blanket from the closet and spread it out on the floor where we would have more room. We moved to the floor where Gina continued titty fucking me as I pulled my s****r up to sit on my chest and began licking her pussy darting my tongue between the soft pink lips as I played with her small jiggling titties. Gina sucked my cock into her mouth once more bobbing on my hard shaft for a few minutes. I couldn't see what Gina was doing as my s****r ground her pussy against my face. Suddenly Gina stopped sucking me, I could feel her hands on my pulsing cock. Then without warning Gina stradled me and shoved my dick deep inside her hot wet pussy and started rocking back and forth, moaning as she ground herself onto me. I thought I would pass out, her pussy was so tight around my thick cock sliding in and out as she rode me hard. I could feel the muscles of her pussy as they contracted squeezing down around my aching shaft. Faster and faster she went as her moans grew louder. "Oh my god your cock feels so good in me. I think I'm going to cum!" she cried out. I pushed my s****r off of me then pulled Gina down on top of me giving her a kiss as I rolled her onto her back. She bent her legs up with her feet on the floor as I dove down on her spreading open her cunt and began licking her madly. She was so wet and juices had begun flowing from her swollen pussy as I wiggled my tongue inside her. She shouted "I want your fat cock inside me now. Make me cum." I got up between her open legs and drove myself deep into her glistening pussy and started pounding her hard, my balls slapping against her ass with each stroke. She put her long legs around me pulling our bodies together as I rammed into her heaving pussy. She let out a loud moan as she tensed raising her ass off the floor. I arched my back and began to shutter as I felt my cum begin to shoot deep inside her. She pulled me into her with her legs as I squirted my cum again and again. I had never cum so much at one time, I thought it would never stop. She loosened her grip on me letting her legs fall to the floor. My cock throbbed so hard it almost hurt as I slowly pulled it out of her. I laid on my side with my head between her legs as I licked up some of the juices running out of her. My s****r quickly began sucking on my still hard cock covered with our cum until it was clean. I laid on my back nearly exhausted trying to catch my breath when all of a sudden my s****r climbed on top of me. "Now it's my turn big b*****r. I've wanted to fuck you for so long." she said. With one swift move she had my cock buried in her snatch and was bouncing up and down. She pumped me wildly for 2 or 3 minutes then screamed as she said she was cumming. Thrusting upward with my hips I shot a load of cum into her, but it was just a couple squirts. Gina had really drained me and there wasn't much left but it sure did feel good anyway. Afterwards as I began to think more clearly, I started to panic. I had given no thought to using a condom! Oh shit! What would I do if I had just gotten Gina and my s****r pregnant. Fortunately for me I learned they were both on the pill and there shouldn't be any problems. I was so relieved. I made sure the next time I played around I had some condoms handy just in case.
