Profesor eróticus (1981)

Starts with this blonde MILF in a bathroom, tits out, going down on some older dude with glasses. She’s got that short wavy hair, slim but not skinny—looks like she’s done this before. The guy she’s sucking is sitting on the counter, taking it easy while she works her mouth up and down. Another younger guy stands right there, shirt off, waiting his turn or just enjoying the show. Lighting’s bright, so you see everything—no shadowy BS, just straight-up oral with a side of anticipation. Later, the vibe shifts to a bedroom where a blonde and brunette tag-team a dude with a vibrator, but the bathroom scene is the money shot here.
