Movie description: "Working Her Ass Off". LaSirena keeps her ass big, juicy and fuckable by putting it to work on the regular, and what better way to stay in shape than shake up your routine? Today she's on the bike working up a sweat as she pedals her ass to perfection. Fellow gym goer Ricky Johnson can't resist her delicious booty and interrupts her solo sweat sesh with some oil and his big, hard cock. Looks like her ass is about to get a real workout.
