When you're having sex with a woman who's having their menstruation, and when you finger/fist her pussy or grab your cock after penetrating her, your hand gets stained with blood. After this, for some reason you have to lay your hand on the sheet, and your hand will be printed on it, just like Wilson in Cast Away.
Man, I thought I'd get extra charged because of the Wilson I accidentally made on that Motel bed.
The Wilson is a sex move based on the film Cast Away featuring Tom Hanks
To perform The Wilson, you first start by fisting a woman while she's on her period, now with a blood covered hand you make a hand print on her face while fucking her
Hey, I totally gave that chick from the bar The Wilson last night. My bed sheets are ruined.
