Hi, i'm mark 16 years old. A normal teen boy with the usual teen interests. I'm about 1,8m tall, weigh about 75kg, blue eyes, dark brown hair. I'm no superman, but keep myself in decent shape. I have a stepsister, Lisa who is 18. She is tall, slim, with long light brown hair, and beautiful C cup breasts and a nice round butt.
I always sneak a peek at her whenever i can get a look at her body. But never actually thought about having sex with her, until tonight that is. We were very close, and had quickly become good friends when our parents started dating, and later married. Our parents was going away for the weekend.
Taking a romantic getaway as they usually do a couple of times a year. Leaving me and my 18 year old stepsister home alone for the weekend. After saying goodbye to our parents, i went up to my room. It was Friday afternoon and raining, so it looked like it would be a boring evening. My stepsister came into my room without knocking. She never knocked, but i didn't really mind. She asked if i had any plans for the weekend. I told her i didn't have any special plans, staying home tonight, maybe see some friends tomorrow and Sunday.
She told me she was going out with her friend Tina that night.
They planned to go to a party and would probably be home late. And she asked if i was OK with being alone for the night. I told her it was no problem and to have fun.
Is a bit of a party animal, and liked going out on weekends. I knew she wasn't a virgin, but she was no slut either. Although i knew she played around with Tina sometimes, but they were never more than friends with benefits.
After Lisa left for her party i relaxed at home. Fixed myself some food, watched a movie, and played on my computer. I used the opportunity to jerk off to some online porn since i had the house to myself (i'm usually a bit shy about this when others are home, since i'm afraid to get caught). And i went to bed at around 11pm. More out of boredom than sleepiness. I woke up a few hours later, the clock on my bedside table told me it was about 1.30am.
I realized the sound that had woke me, was my sister returning home. By the sounds of her unsteady shuffling i could tell she was drunk. I heard her going into the bathroom and turning on the shower. I turned around and tried to go to sleep again.
I was half asleep again, when i thought i felt a movement on my bed. But i figured it was my imagination so i kept trying to sleep. Suddenly i felt something touch my chin, i opened my eyes and realized my sister was lying in my bed beside me wearing only bra and panties.
Clearly drunk. She smiled at me. Then she leaned in and kissed me, passionately, her tongue finding its way into my mouth playing with my tongue. I was too drowsy from sleep and surprised to really comprehend what was happening.
But her kiss felt good, far better than any kiss i had experienced before. I had only kissed a couple of girls before. She broke the kiss, still smiling.
It almost felt like i was dreaming. She pulled my duvet off and moved closer to me. Our bodies was touching now, she put one leg on top of mine. Then she kissed me again. As she did, she put her hand on my boxers and gently rubbed my cock (which was getting harder by the second) trough the thin fabric. When she broke the kiss again i moaned from the pleasure of her touch. She asked if i liked it, and i all i could do was nod. Then she put her hand inside my boxer and pulled my cock out, all 16cm of it hard as a rock now.
She started to slowly stroke it.
By now i was fully awake, but too horny to care if she was my stepsister. We kissed again, and this time i had the presence of mind to kiss back. I put my arms around her, letting my hands glide over her gorgeous body. Then she said "I want to fuck you", all i could think or say at this point was "oh yes". She sat up and took of her bra, letting her beautiful tits swing free. Then she slid off her panties, revealing her shaved pussy glistening with her own wetness.
It was the first time i saw a pussy in real life, and the sight of her naked body made me so horny it almost hurt.
She pulled off my boxers, i was now laying completely naked in front of her. She straddled over me. Took my cock in her hands and guided it towards her wet heaven while slowly lowering herself onto it. It felt so amazing feeling my cock glide into her tight pussy. She lowered herself all the way down until i was completely inside her. She let out a soft moan, and then started slowly rising and lowering herself on my cock. Both of us moaning in pleasure now. I was dizzy and my head was numb from pleasure, and all i could do was lie there as my stepsister was fucking me.
I didn't last very long that first time, only a few minutes. I let out a long loud moan as i shot my cum inside her. She stopped riding and just sat on top of me for a few seconds as my cock softened inside her pussy. "mmm that was good" she said as she laid down beside me, "yes it was" i answered.
Then she said "but i'm still horny". We kissed again, and then she took my hand and guided my fingers inside her. We lied like that for a while, kissing and me fingering her pussy. Her breath became heavier and faster as she was nearing an orgasm. My cock was hard again by now. And she took my fingers out of her pussy, "no, not like this" she said "i want to cum on your cock".
She got back on top of me and started riding me again, this time taking my hands and let me fondle her tits while we fucked. I lasted longer the second time, and was even confident enough to let my hips rise to meet hers as she came down on me.
After a little while she let out a loud long moan as her orgasm raced trough her body. The look and feeling her orgasm on me made me shoot my load into her a second time.
"Thank you" she said as she laid down again, putting her arms around me. We lied there holding each other and kissing for a long time. And then she fell asleep, her arms still around me. I couldn't sleep for a long time, i lay awake thinking of how i had been fucked by my own sister.
We woke up late in the morning. She was smiling (shes always smiling), but she said she had a bad hangover and needed a shower. We didn't speak much that morning, but in the early afternoon she came back into my room.
Her hangover almost gone. She was uncharacteristically shy and quiet. "about last night" she said, "i hope i didn't hurt you or made you feel bad". I told her i had been really surprised, shocked even. But i also told her it had been one of the most amazing experiences of my life. She told me she was re-leaved to hear that, and that it had been wonderful for her too.
And she said she might like to do it again some time, but sober. I told her i would like that. We didn't have sex again that day, but spent the day at home relaxing together. But later we did it again, but that's for another story
