Kelly Stafford appears in the last 15 minutes in a scene evidently left over from Super Moto Hard. An older blonde uses her knickers as a starting flag then is gangbanged by the mechanics. Kelly joins in and tries to drink everyone's cum.
In an earlier scene Rocco appears to be experimenting with using a sigmoidoscope as a camera. Why anyone should find this erotic escapes me, but another scene in which the owner and a couple of female staff of a hotel join in with Rocco and three girls is pretty hot.
