Vampire Bottom

A kinky term referring to a submissive person who provides little or no expression or movement in response to the stimulations of a dominant person, often by laying silent and motionless during play (like a vampire).

I've met my share of vampire bottoms. Once, I tried flogging, tying, clamping, and even fucking a guy for hours, and I maybe got a single whimper and a twitch the whole time we played.
