Houdinis magic carpet
The act of masturbating in front of a woman onto a towel in her carpeted bedroom thats also dimly lit. But little does she know you have some fishing line tied around your big toe looped around the tag of the towel on the ground. And just before you ejaculate you swing your foot back sending the towel flying backwards exposing the carpet in her room, you then proceed to cum all over her clean carpet.
Oh man I visited Tracey the other night. She was irritating me so I grabbed some fishing line and surprised her with A bit of the old Houdinis magic carpet action. She wasn't happy but was getting the steam cleaners in that week anyway.
