Lust At First Bite (1978) (FullHDRip)

Starts with this blonde MILF—curvy, big tits, looks like she just got out of something intense. Her chest is all red like she’s been worked over, and she’s sitting in a bathtub in what looks like a medical room. Then you got two dudes: one’s a gray-haired older guy with a serious face, slicked-back hair, and he’s in some lab-looking place with skulls and candles. The other dude’s dark-haired, lean, looks Middle Eastern, and he’s in a dungeon vibe with chains and dim lighting. They’re both into the whole power/dom thing, talking like they’re running some kind of experiment on her. Later, the girls take a break—two slim chicks, one blonde, one brunette, doing each other’s nails on a bed, all soft and intimate. But the main event? The MILF getting handled rough, doggy style, and taking it hard. Camera work’s solid, gets right in there for the close-ups when she’s getting pounded.
