The Duct Tape Killer (1998)

A muscular Asian guy in his 20s or 30s dominates two young, slim Asian girls with long dark hair in what looks like a gritty apartment setting. One girl gets gagged with duct tape and tied to a chair while he fucks her from behind in doggy style, grinding hard. The other girl takes a turn on her back, legs spread wide, getting drilled in missionary with close-ups of her face — lots of moaning, eyes rolling. There’s some sketchy knife play in a close-up, her neck glistens like she’s been licked or splashed with water, blade tracing her collarbone. The lighting stays dim throughout, mostly yellowish, giving it that grimy, voyeuristic vibe. Camera work is steady, medium shots for the gangbang stuff, tight close-ups during the knife and facial.
