Christina La Perverse (1980)

Christina La Perverse is in red lingerie, boots on, playing with a sex toy on a couch — dim lighting, up-close on her hands and the toy sliding in and out. Scene shifts fast to a bedroom where she’s on her knees sucking a slim brunette guy, head bobbing hard, throat visibly working as he groans. Cut to the living room again — now it’s a three-way with two slim brunettes and the same guy, all naked, one girl riding him while Christina eats her out from behind. The camera stays tight, no wasted angles — you see every thrust, every lip contact during the girl-on-girl oral. Later she’s on all fours, getting pounded doggy-style while the other girl jerks off watching, then joins in with a strapon. Nothing fancy, just straight-up rough sex with a focus on access and wet sounds.
