I had often thought about her like this . So with out any response my arms was around her and our lips was locked . I lift her off the floor and placed her on my bed . She was so sexy laying there in a black dress . I got in bed next to her and started kissing and fingering her as we witch p*** on my phone to give her some references to what we was doing . After a bit I lift her dress and started eating her out . She had a great taste I was in love. Next I got on top of her and with a hard shove I was haf way in she cried out loud sobin it to big . With how loud she was its good our parents wasn't home . I slowly moved in and out going a little deeper each time . I got most of my 11 in d*** in her to this day I have trouble getting all the way in . So once she stopped crying I started getting ruff with her she loved it . We f***** 3 times that night she got a lot of c** we did every position I could come up with and the last time we even did anil . The next day she came home late . I asked her how her boyfriend did .
