This happened a few years back when I was in High School. I had spent the night at a good friends one Friday evening. When I woke in the morning, I knew his mom was gone (parents split up), and remember that my friend had gone to baseball practice until the early afternoon. I decided to take a quick shower when I got up before I was to head back to my house. There was no one home except my friend's sister whom I'll call Lauren (not real name). I walked into the bathroom and turned on the water. It was an older shower so I stood outside for a moment waiting for the hot water to kick in. I dropped my towel and was waiting naked right outside the shower when the door to the bathroom suddenly swung open.
It was Lauren who was a year younger than I, looking amazing in a tight T shirt and her underwear. 'Oh, I didn't realize there was anyone using the bathroom,' she said. I was first really embarrassed, but I saw her eyes completely fixated on my cock and I started to wonder if it had been strictly coincidence that she entered. She walked over and turned the water off in the shower and told me that I shouldn't be using it, and to follow her to the other shower because it worked much better. She stopped in her room on the way and asked if I would come in for a minute and help her with something. As soon as I stepped in the room, she slammed the door behind me, ripped off her shirt, and gave me this really sexy look. 'No one will be home for at least a few hours, and I'm dying to get a better look at that cock of yours.' I was standing there wearing only a towel and getting quite turned on.
We started started kissing and in no time she was completely naked and I was rock hard. She had a beautiful pussy and she took my hand and guided it down to her lips. She must have been really sensitive because it took only a few seconds of rubbing her clit before she was moaning wildly. I placed a finger, then two up into her sizzling pussy while continuing to rub her clit. Before long she was screaming and her pussy was totally soaked as she came really hard. After a minute or so she grabbed my cock and started stroking slowly as I continued to work away at her beautiful vagina. She must have been building up to another orgasm because she started breathing really heavily and stroking my cock faster and faster. 'Oh shit, I'm gonna come again so soon,' she cried out, 'I want you to shoot your load all over my tits,' she continued.
Her nipples were rock hard at this point and I was starting to get damn close to losing it just looking at her sexy body. She came again shortly after and then focused all her attention on me. She started furiously pumping away. She had a possessed type look in her eyes and just started saying, 'Yeah baby, I want it all over me, I want to see all your cum all over my tits, cmon baby, give it to me, yeah, I need it now.' She was stroking my cock so fast now and I was right on the edge. I let out a moan and started shooting wave after wave of steaming hot cum all over her chest. After she had milked my cock dry she told me how turned on she was, and how this was the best orgasm she had ever had.
