It would be more accurate to describe these performers as two plump girls and two slim girls. Shonna Lynn is the closest thing to a chubby girl on this tape, and even she's pretty much the right size to support her ample boobs. She has a pretty face with plenty of baby fat. Her partner certainly has a fine time shtupping her with his generously proportioned love-sausage before squeezing out his cream onto her face.
The second scene features a very pretty (but slim) blonde waiting for Captain Bob to arrive. Of course she starts removing her clothing and then fucks the first guy who stumbles across her. From there we move on to an exotic beauty with enormous breasts who gets a workout from John West. The tape ends with another blonde who eagerly accepts the cock of a boy she's seen casually on campus.
