This story took place a few days ago and it might have been the best experience of my 16-year-old life. I was over my girl-friends house, her name is Hannah, and her parents were out for the night and they wouldn't be back for a while, and her sister was upstairs in her room.
We were cuddling downstairs in the basement, her head was on my shoulder and my hand was around hers, when her sister came downstairs and told us that she was going over her friends house for the night and that she was probably going to sleep there. Five minutes later when she had left the house Hannah whispered over to me, 'My sister is such a horndog, her and her friend fuck each others brains out all the time, they can get pretty loud.' At this comment my dick got semi-erect and she could tell, and all she did was smile. The farthest we had gone together was just cuddling and kissing, and the sexual tension between us was definately growing.
As we were cuddling I flipped on the TV to check what was on and a lingerie show turned on. 'Hey, would you want me to do that for you sometime?' Hannah said out of the blue. By now I was struggling to keep my cock from becoming rock hard. 'Of course I would, how about right now?' I asked. 'I was hoping you'd say that,' a second later she came downstairs with a bag of clothes and a sheet so that she could change behind it. 'The deal is, since I'm in my underwear, you have to get in yours to.' I happily obliged and soon she was parading around the room in sexy lingerie. As she was walking around I was getting hornier and hornier and soon my cock was rock hard, and she could definately tell. She sexily walked up to me in a black lace thong and matching bra, and said in a very seductive voice, 'do you want help with that Brian?' All I could do was nod as she took off her thong and bra, and I could my first view of a beautiful pair of 36C cup breasts and a almost completly shaved pussy with a little runway strip of hair.
She took off my boxers revealing my hard thick cock, reached for some lube that was in a nearby closet, and lubed up my cock. She took her tits and gave me a tit job, using her perfect tits to massage the head of my cock, and then my whole shaft. After about 10 minutes I grunted loudly and told her that I was about to cum. She continued to move her tits up and down along my cock, and soon I shot 6 or 7 ropes of hot cum all over her body. After that we kissed passionately and cuddled with each other throughout the rest of the night. Hopefully more happens between us and when it does I'll definately update.
