The Best Of Everything (1974)

This one’s all about bedroom action. A slim blonde white girl with fair skin gets busy with a thicker, dark-haired guy. He starts by kissing her neck, then dives right in for some intense oral, burying his face between her legs. She returns the favor, sucking him off while lying on her back. The camera gets up close for the blowjob, and you can see every detail. They fuck hard, with her riding him and some solid missionary action. The dim lighting makes it feel intimate, and the angles are great for catching all the action.
