Get the Fist Cummug. Not to be confused with "Muppet necking", where an individual uses a muppet to simulate a soft velvety blowjob. Muppet fisting is where a person usually with extensive hands and arms. Fists, their partner, who in this case is usually on the smaller side, past their wrist and then, taking advantage of the size difference, uses their arm strength to lift their partner in the air. Impaling them on their fist in a way that's reminiscent of a person operating a muppet.
"Holy shit, did you hear what happened to July at the afterparty?" "Yeah, man Viola from the basketball team was Muppet fisting her in the living room in front of everybody; guess she became the MVP's trophy at that point"
