Madam's handjob
A woman peels off her undies and uses them to give a guy a hand job so the cum soaks in like a posh cum trap.
My neighbor did this to her husband in the hallway and left a trail of cum all the way to the elevator.
My friend’s aunt used her undies on her brother and then told him to walk home with the mess.
My cousin did this to my uncle in the car and ended up getting a ticket for the mess.
