(As of this writing, I am now 29 years old and would like to share a fun experience I had in July of 1996 when I was 20. Some of you may not like the content due to it being me and my sister, so you can stop reading now if it might offend.)
I understand messing around with your sister might not be a good thing, but it was a one time thing and done on the spur of the moment between 2 drunk siblings. Jessica was 19 back then, and like I said I was 20. I'm Jason by the way. I'll describe how we looked at the time.
Me: About 5'9", thin, black hair, fair looks and my cock was an even 8 inches when hard.
Jessica: A buxom girl, maybe around 160, which is not bad. She had light brown hair to her shoulder blades, very busty and she was really cute. To be honest, she slightly resembled Traci Lords in the face and hair department.
We ended up alone one Saturday night when our dad went away on a fishing trip, and mom decided to spend the night by our Grandma. I remember it was a stormy night and very windy; we're from Chicago and if you've ever been here, the wind is unbelievable.
With nowhere to go and nothing to do, Jessica and I ended up raiding the bar in the basement, and found a bottle of Jaegermeister to go with the beer we were drinking.
It was around 10pm if I remember correctly, and we were having fun drinking when Jessica wanted to take a shower and get more comfortable, sensing a long night of partying ahead. She came back ten minutes later with nothing but a towel on and her cleavage very visible - her tits were really big. I figured I wasn't going to be the only one sitting around in hot clothes, so I told her I was going to take a shower too. It was hot and muggy, and drinking shots of Jaeger made it even hotter. I have a little towel wrap-around that fastens with Velcro, and when I’d finished showering, I just came out in that.
So there we were partying in towels and getting massively buzzed.
Jessica got up and turned the radio on to drown out the thunder and rain. We played a game where you had to drink a gulp of beer, a shot, and then another gulp of beer - we were getting pretty loaded.
Jessica was dancing to the music, and I acted like a fool and started dancing around like an idiot. I kept bumping into her and she'd push me and we'd get into little shoving matches. I grabbed her towel and pulled it off her and she chased me around the living room; we were laughing so hard. Watching her big tits bounce around was a pleasure and when she tackled me onto the couch, I realized had half a hard-on.
She tried pulling my towel wrap off and I struggled to hold it in place, but she won out and ripped it off me freeing my cock. She was staring at my cock, which was fully hard by now when I got up and lunged at her. She screamed, threw the towel and ran. I chased her around the living room table where she stopped to catch her breath. We walked slowly around the table for a couple of minutes and her tits were just huge and her nipples were hard. She must have gotten just as excited as I did wrestling around on the couch. I busted her staring at my cock and called her on it to tease her.
She said in these exact words, “Man, your cock is big!” and then took off running and laughing again.
I caught up with her eventually, and wrapped my arms around her from behind, and we fell on the couch again. We had a huge sectional so there was plenty of room to wrestle around on it.
I was running out of steam and I was feeling drunk and happy. A few times while we were grappling on the couch I grabbed a handful of titties, and Jessica grabbed my cock once. Eventually I gave in and Jessica ended up straddling me with her legs next to my waist and her pussy on my stomach with my hands pinned above my head. We were both out of breath and her tits were inches from my face. I stuck out my tongue to lap at them and she laughed and pulled my back a little. I was laughing and kept trying to lick her titties. She was too tired to fight and relaxed as my tongue licked her nipple.
I took turns licking and sucking each tit and Jessica had her eyes closed and scooted down a little. Her pussy was now over my cock, and I could feel the warmth of her wet pussy lips. She let go of my arms and rested her hands above me. I squeezed and sucked her tits and then she started sliding her pussy on my cock. I reached down with my left hand and slid my fingers under my cock to lift it up so it would go in her pussy. It worked and my cock was now sliding in and out of Jessica's wet pussy.
She sat straight up and put her hands behind her on the couch and her tits were thrust out, and I was looking right at my cock appear and disappear up her pussy. With us being drunk and the music blasting I don't think we cared too much about what was happening. Normally I probably would have had to cum already, but the liquor was keeping me hard and giving me a lot of stamina.
Jessica rode me for a few more minutes and then got off me. She laid on her back and put her left leg over the back of the couch and her right leg up in the air. I grabbed her ankle and guided my cock in her pussy. I fucked her hard and fast for a good 3 minutes until she came and screamed loud. I still didn't cum though.
I pulled out and sat on the couch exhausted, but Jessica didn't want to leave me hanging and started stroking my cock. Soon she took me in her mouth sucking my cock fast and stroking it hard. I felt like I was about to explode and she stopped sucking my cock and pumped it hard with both hands. I erupted with a huge blast of cum that went all over her hands and on my stomach. She squeezed the last drop out and went to clean up.
After this we hardly talked for a few days, and then it was all back to normal.
It wasn't planned as you can see; it was just a good time that we had that one particular night.
