Run, Virgin, Run (1970) (Better Quality)

Starts with this redhead in a tiny red bikini bottom, no top, running across a grassy field like she’s trying to escape. Guy’s got a black tie on over a yellow shirt—looks like he just left the office or something. He catches her, grabs her arm, and she’s laughing but also kinda fighting back. Feels like roleplay, not just rough sex. Later they’re in the woods at night, same energy—him pinning her against a tree, her legs wrapped around his waist while he pounds into her. Camera’s shaky but you get a good look at her small tits bouncing every time he slams in. Only downside is the lighting’s dim, but you can still see everything. Guy’s got decent stamina, keeps going for a while before pulling out and finishing on her stomach.
