her breasts as she slowly moved up and down my cock.

My parents were gone on vacation and I was home alone. I decided to go swimming so I got a towel and changed to swim trunks. Then I thought that s stupid why swim trunks? So I left them in my room.A few minutes later while I was in the pool the phone rang. My girlfriend Amanda who I had never done anything with before called me and wanted to know if she could come over.Now Amanda and I were fairly straight. I had one other girlfriend before who gave me a blow job once. She had let a guy feel her up twice before. Sure I said but realize that I m not wearing any clothes right now. Sounds good to me she said hanging up.I started to get dressed but then I thought hey she had her warning. About ten minutes later a very naked Amanda came walking out in a towel just barely covering her. She had come in and taken off her clothes inside my house!!She dropped the towel and I saw her naked for the first time. Very little hair if you know what I mean. She slipped into the pool and we started swimming circles around each other.By this time my cock was fully awake and ready to go!After what seemed like an eternity she swam towards me and we embraced. I leaned down and kissed her breasts caressing one of her tits with my mouth. She moaned and ducked under the water....all of a sudden I went stiff...she was giving me a blow job underwater!That lasted for about 20 seconds before she came up for air. We kissed and then I led her out of the pool to the grass. I laid down and she climbed on top of me.The feeling when she slowly sank down on my cock was incredible. She slowly sank down about three inches and then pulled back up. I nearly went off right there.She slowly kept doing that and after about three times she pushed a bit harder and she was now a full-fledged woman. After a minute of getting used to it she picked up the pace again.I laid there on the grass fondling her breasts as she slowly moved up and down my cock. As we were getting close I asked her what she wanted me to do and she said she was on the pill.She quickened the pace again and all of a sudden arched her neck back as she came. I came at the exact same time flooding her with my cum.She sank down my cock still deep inside her and we kissed intensely. Finally we stood and walked into the pool again to clean off. Afterwards we went into the house showered together got dressed made dinner and watched a movie.We have continued to date and we sleep together once in a while. We re engaged now and we plan to get married when we both reach eighteen.
