L’insegnante (1975)

Starts with some older dude with gray hair and a suit just talking to the camera in what looks like an office or shop—nothing wild, just him gesturing like he’s explaining something. Then it cuts to a bedroom where a skinny blonde in a tiny denim skirt with no top is bent over a table. White guy with rolled-up sleeves and a tie stands behind her, gripping her hips while he lines up for doggy. You get a clear side view of her ass and tits bouncing as he pounds into her. Later, two petite Asian girls with long black hair are topless in a mirror, feeling each other up—one’s got her hands all over the other’s tits while they kiss. The lighting’s dim but you still see everything. No crazy positions, just straightforward fucking and girl-on-girl action with decent angles.
