Solo Sunny (1980)

A slim redhead girl with curly hair and a bandage on her foot spends most of the scene alone in what looks like a messy apartment. She’s wearing casual clothes, then undresses and starts touching herself on a couch — slow at first, just teasing with fingers around her pussy. The camera lingers in close-ups during the solo stuff, especially when she spreads herself open and rubs her clit in dim light. Later, a young redhead guy shows up — probably late teens, skinny, no facial hair — and joins her in the hallway. They don’t talk much. He eats her out from behind while she leans against a wall, then switches to doggy style with steady thrusting. Her foot injury doesn’t stop her from bending over hard, ass fully exposed. The whole thing has a raw, quiet vibe — not loud or flashy, just real-looking sex with natural lighting and tight framing on the action.
