Before & after effect?
The wife takes the hint and says, "OK, but I have to use the bathroom first." So off she goes but on her way back she trips over a piece of carpet and lands flat on her face.
Her husband jumps up and exclaims in a concerned tone "Oh my little honey bunny, is your nosey-wosey all right?"
No harm is done, so she jumps into bed and they have mad passionate sex for three hours. Afterwards, the wife goes off to the bathroom again, but on her way she trips over the same piece of carpet and again lands flat on her face on the floor.
Her husband looks over and grunts "Clumsy b*tch."
