Guess which of those surrounding penises is your boyfriend's! If you guess wrong, you'll be gang-raped by four strangers right in front of your boyfriend! SDAM-010

Any couple can recognize their boyfriend's penis. Looking at the five protruding penises on all sides, they guess the penis based on its "appearance", "taste", "texture", "licking", "flavor", and "feeling of sucking". If they guess correctly, they get a high reward, but if they guess wrong, they will be fucked by other penises in front of their boyfriend!
