Worse sex I had sober, was with a chick who got on EF just to see what site I was looking at (not my current wife Annabelletx) when I told her I was on my message board typing while chatting with her on the phone once. She got on EF for a couple of weeks and then left after posting and chatting a bit.
Basically, she gave horrible head, no suction, teeth dragging (my dick went limp), then when I went down on her she did not make a sound or move at all. Once I started fucking her, again she just laid there...and after about 5 minutes of this I pretended to cum then went to the bathroom and flushed the condum so she would not know and just chilled and chatting with her for a couple hours before going home. She was a good conversationalist. A couple weeks later we were chatting and she admitted that she did not think we were sexually compatable, and I admitted to faking my orgasim.
