The Boobyguard (1993)

Starts with the blonde—slim, inked-up, small tits but a tight little body—lying on her side making out with the guy. He’s got decent arms and chest hair, not some gym bro but looks like he can handle himself. They switch to her on her back, legs spread, and he goes down on her while she plays with a piece of fabric like she’s trying to muffle the moans. You can see her nipple piercing glint in the dim light—nice detail. Later, the brunette joins in, same slim build but with bigger tits and a redhead vibe (wig or dye, not sure). She rides him on a chair in what looks like a home office, bookshelves in the background. The camera gets right in there for the close-ups, especially during the oral parts. No crazy acrobatics, just solid fucking with good angles on the action. Both girls take turns getting pounded, and the lighting makes it feel intimate, not some overproduced set.
