Prisoners of Sex (1990)

Dude sets up a sex swing in what looks like a home dungeon. First up: a skinny Asian girl with long black hair and a slim Black chick with long wavy hair. They’re both into it, taking turns on the swing while he watches and joins in. The Black girl’s got a tight body and rides him reverse cowgirl—good angle on her ass the whole time. Then they switch to a 69 on the bed, and you get a clear shot of both of them going at it. Later, the Asian girl bends over a glass table while he pounds her from behind—her tits bounce every time he slams in. Lighting’s dim but you see everything, especially the close-ups on their faces when they’re getting off. Solid mix of positions and a good pace, no dead air.
