A rim-seat is an adjustable stool with a toilet seat attached that can be lowered over a guy's mouth so he can lick your asshole and give you a randy rim-job.
My cadet roomie, Matt, bought a rim-seat, and when he wants to be rimmed, he brings it out and has me lie down on my back underneath it so I can give him a rim-seat-gasm with my tongue up his asshole!
