O Cafetão (1983)

Starts with this skinny Asian girl in a striped top looking nervous in the kitchen, then cuts to a basement where she’s tied up with ropes against brick walls. Two guys in their 30s with short dark hair take turns bending her over while the third, a bigger dude, watches and jerks off. The lighting’s dim but you can see everything—her tits bouncing when they switch to doggy, her mouth stretched around one guy’s cock while the other fucks her from behind. The third guy finally joins in, shoving his dick down her throat while the other two keep pounding her. No fancy editing, just raw, close-up shots of her getting used hard. The angles are low, making it feel like you’re right there in the room.
