Sapiches (1982)

Starts with this skinny brunette in a pink top bent over a small table in what looks like a kitchen. The guy behind her is lean, dark hair, no shirt, and he’s not wasting time — goes straight for anal. Camera gets right in there, shows her face twisting while he works her over. Another guy with short curly hair watches, then steps in for his turn. The lighting’s dim, but you can see everything — her tits pressing against the table, his hands gripping her hips. No fluff, just straight-up rough stuff with good angles on her reactions.
