Otona no omocha: Dacchi waifu repôto (1975)

Starts with the dude holding the brunette from behind, her arms pinned while he kisses her neck. She’s got ink on her arm and a tight, toned body—looks like she’s into the rougher stuff. Then the MILF joins, and things get messy fast: one girl on his face, the other sucking him off, all in the same shot. Camera’s above so you see everything—no hiding. Later, the brunette’s bent over the bed, ass up, getting pounded from behind while the MILF watches. The lighting’s dim but you still catch every detail, especially when they switch to missionary with the dude going hard. Ends with him jerking off solo, but the real action’s the threesome—good mix of oral and full-on fucking.
