muppet wank
During coitus, one partner (or a third person) inserts their full hand into the anus of the woman and grasps the man's penis through the walls of the rectum and vagina. They then proceed to masturbate the penis while simultaneously fisting the woman rectally.
Dude, I got muppet wanked by my girlfriends BFF during a threesome last night.
Wank muppet
The sock you use to cover your cock which catches your cum when masturbating.
He is such a wank muppet!
