Tina my sweet fuck buddy SeXStoRY

As a I was growing up at home my s****r often had friends over on the weekends. I enjoyed seeing them in thier skimpy bathing suits laying in the back yard sunning. I tried to find some reason to be outside where I could watch them closer. On one particular day my parents were gone for the weekend and I was tasked with making sure they didn't get into trouble and behaved themselves. I walked outside to check on them. They were talking and giggling about something. I asked them how they were doing and if they needed anything. They asked me to bring them a soda from the fridge. I went in and returned with one for each of us. They invited me to join them on the large blanket spred out in the grass. I sat down beside Tina, my s****rs friend as we sipped our drinks. Looking over her sweet young body glistening in the sun I started getting a bit horny and my cock was stiffening in my shorts. I pulled off my shirt and placed it across my lap to hide my growing boner. After a short while I got up to go inside feeling a great urge to masturbate. When I stood up I saw Tina look at me and the bulge in my pants as I walked to the door. Just before I went inside I heard them giggling and looked back at Tina. She had a big smile on her face as I went inside. I went to my room and jerked off thinking of her. Later that evening we had all settled into bed for the night. As I layed on my bed my thoughts returned to Tina and once again I found myself with a raging boner. I slipped out of my underware and began playing with my throbbing hard cock. Moments later I heard a quiet knock on my door and before I could cover up Tina opened the door and said "Can I come in?" The room was dark as she stepped in closing the door behind her. I said "What do you want Tina, I thought you were asl**p." as I pulled the sheet up over myself. She walked over and sat on the side of my bed and said "Your s****r was telling me about the time she walked into the bathroom and saw you naked, and told me how nice your cock was." I didn't know what to say to her. "Today when you were on the blanket with us I couldn't help noticing the big bulge in your shorts and it made me so horny." I looked at her in her little nighty with her perky tits poking at the material and my cock throbbed under the sheet. She said "I would love to see for myself how nice your dick is, will you let me see it?" I thought I would cum right then. "It seems a bit strange don't you think, sneaking in here and asking to see my cock?" She quietly giggled and said "I'm so horny and just had to come check it out, won't you please let me see it? I'll show you my titties if you like." I told her OK but she had to be quiet so we didn't wake my s****r. With that she lifted her nighty over her head and tossed it on the floor. Damn she had the most beautiful firm tits, nice and round. They must have been 34C at least and her nipples were getting hard. My cock stood straight up under the sheet as I pushed it down to reveal what she wanted to see. She said "Oh my you do have a nice one, can I touch it?" I told her to get up on the bed with me so I could reach her tits as she played with me. She knelt beside me as she explored the length of my shaft and fondled my balls. I raised up on my elbows and leaned over kissing each of her breasts and sucking on her nipples as her hand slid up and down my cock send waves of pleasure through my body. I said "Have you ever sucked a guys cock before Tina?" She said "No, but I'm ready to try now." and she lowered her lips to the tip of my dick and began licking around the head as she stroked me. I layed back to enjoy the feeling of her soft mouth as it slid down onto my aching cock. As she bobbed up and down I reached between her legs to feel her pussy, working my fingers under her panties. Her pussy felt hot and wet as I slipped my finger inside her. She began to moan softly as I slid my finger in and out. I pulled my hand to my mouth tasting her juices, I felt my precum begin to ooze from the end of my cock and she licked it up saying she liked the way it tasted. I reached over pulling at her panties sliding them off her legs. I said "Are you ready to feel my cock inside you?" She moan yes, I want it. I guided her on top of me and reached down putting the end of my cock at her pussy lips sliding it back and forth a couple times before giving a little push making in slip inside. Gently at first I eased it in bit by bit until she was sitting completely down on my shaft. With my hands cupping her ass cheeks I began lifting her up and down till she was riding me on her own, pumping her tight wet pussy on my throbbing cock. She started going faster and the bed began to make squeeking sounds and her moans started getting louder. Hoping to keep the noise down and not wake my s****r, I pulled her body down onto mine and began passionately kissing her as I worked my hips driving my shaft in and out of her cunt. In a few minutes I felt her body shiver and she moaned "I'm going to cum." I pumped harder and moments later her body stiffened and I felt her cum as I shoved my cock deep into her as I exploded releasing a huge load of cum, squirting my juices 4 or 5 times into her pussy. She collapsed on top of me as we kissed and held each other tightly. After a few minutes she got up off my dick and the cum flowed out of her pussy running down my shaft to my balls. She quickly took my cock in her mouth and sucked up our cum and licked every bit from my balls as well. She sat up and smiled at me and said "That was fantastic, I never dreamed it would be so good." I told her she was one of the best fucks I'd ever had, and I hope that we will get to do it again sometime. She gathered her clothes and said "Well, we still have tomorrow night ahead of us before your parents return. I hope you won't mind if I come to see you again." I said "I'll be looking forward to it Tina." and gave her a big kiss before she left. The next night after my s****r was asl**p Tina slipped into my room and we wasted no time getting busy enjoying another fantastic suck and fuck session. I always look forward to her visits with my siter and we've become great fuck buddies.
