Big Thing (1973)
The standout here is the girl — a short, slim brunette with natural tits and a bush. She stays in control for most of the action. The guy spends a lot of time on his back, letting her work his dick with her mouth. She’s not rushing it, taking her time to suck and jerk him off. The POV shots are warm and intimate, giving you a close-up view of her face while she’s blowing him. The fucking picks up after that — she rides him in a couple of positions, and the camera focuses on her pussy as she slides up and down. There’s some fingering too, with the guy really going at it while she’s lying back. The whole scene feels very up-close and personal, with lots of tight shots on the action.
