Looking for source or name of a retro-ish porn video.
In it a girl and guy are banging and an older guy walks in, beats up the dude and throws him down a hill, then rapes the girl on the bed who is tied up.
The (presumed) boyfriend climbs back up the hill to the cabin only to be beaten again by the old guy. The girl begs him not to hurt him if he can continue banging her.
