O Gosto do Pecado (1980)

A 16 year-old girl has a sex scene with a much older man. Over on the bed she lies on her back and he sucks her right tit and holds both tits with his hands. Then he pulls down her panties and he gives her cunnilingus. Then he rolls to the side and pulls out his penis to tug it. Next she's sitting right next to him and apparently masturbating, and we can see her tits. He places her head on the pillow and humps her, and they have simulated intercourse in the missionary position. They rest and calm down for a moment, and his head is resting between her breasts. He reaches between her legs and starts aggressively fingering her pussy. At first we only see her tits and legs, but most of her bush becomes visible between her partially spread legs for about 3 seconds.
