Secrets of a Superstud (1976)

Alright, so this starts with a gray-haired MILF-looking dude in an office chair, just talking like he’s giving some kind of lecture. Then it cuts to a thick Latina with a lower-back tattoo bending over for him—she’s got that curvy, toned body, and he’s sliding a condom on before going at her doggy style. The camera’s right there, low angle, so you see everything. Later, he’s eating her out on a bed, green lamp in the background, and she’s got these big tits bouncing while he’s face-deep between her legs. Then there’s a blonde chick with huge tits who takes over, sucking his dick while he’s lying back—she’s got that messy hair, looks like she’s really into it. The lighting’s dim but you still get a good look at everything. No fluff, just straight-up fucking with solid angles.
