similarly any sexual act willingly undertaken that creates instant and overwhelming remorse can be deemed 'antirape'

In the Game of Rape, the antirape cards are usually jokers. They are the only cards with the power to stop a rape.
If a player plays the antirape card on a rape before the rapist can finish his/her rape combo, the rapist's turn ends prematurely and the antirapist gains control.

The antirape cannot be played on Captain America or the DM Card.
