Ok.. Who was so bad that you still remember it till this day? Everyone has had bad sex.. how about REAL bad sex? The worst was about 20 years ago. This model (she was a "Genisis 'Girl Next Door' " and centerfold) was the worst! She just laid there at first, then started to do this thing with her pussy.. trying to clamp down on my penis. It was distracting to say the least. I tried to get her to change positions, but she would only do it on her back, legs out straight. Then there were the noises. It was kind of like a "oooooh, oooooh, oooooh" After seeing her a few times, I stopped returning her phone calls.
