A man is making love with his wife (well someones wife anyway) and she was lying on her back and he was on top. After a few minutes he noticed that her feet were moving up and down in time with his rythm -how you spell rythm?- So he stopped his thrusting and when he stopped so did her feet. Puzzled he started thrusting again, and her feet started to move up and down again. Again he stopped and so did her feet. By this time she was getting fed up, 'what's the matter ?' she asks. He say to her. 'Why is your feet moving up and down when we make love?' She didn't know she was doiing it so she felt down with her hands and says 'oh, sh*t'
'Whats up?' He asks
'I left my tights on' she replied.
