Simply put, a bunch of guys love fucking their girlfriends in the ass.  All action involves d.p. combinations and anal poundings.

Munchkin-sized Sabrina is saddled with a boyfriend who orders her to start sucking off the pizza delivery guy.  Pizza boy later catches Kate Coleman with her fingers in the till.  Soon his fingers are hard in her ass.

All the scenes are based on hard-nosed play acting, so go for it, if this is your speed.
