Sitter 

A small, heavy-set woman can be referred to as a "sitter".

The term is the antonym of a "spinner" which is a small, petite, thin woman who could possibly spin around your cock like a top during intercourse whereas a "sitter" will just simply sit on your dick like a broken fridge during sex and let you do all the heavy lifting.

Yo, I was trying to mack on Angela that tight Asian spinner at the party last night hoping she'd act like a propeller on my cock back at my apartment, but she bailed early so I picked up her sitter friend Beth. Man, that chick just squatted on my dick all night like she was living in a foreclosed house and wouldn't leave.
