The Big Switch (1968) (FullHDRip)

One of the brunette girls has short hair and a slim, wiry frame — you see her first in a topless group scene with four other women and a guy, all hanging around a dim living room with wine glasses and cigarettes. The group dynamic shifts when they move into sexual territory — it’s not just random hookups, it feels like a planned partner swap. They start with soft stuff: grinding, making out, some handjobs, but it doesn’t take long before clothes are off and they’re lining up for proper fucking. A long-haired blonde rides the main guy hard on a couch, changing pace from slow grinds to quick bounces, her big tits bouncing freely. Later, same girl takes him in doggy style against a wall, while the short-haired brunette jerks him off in front for a dual-penetration tease. The camera stays wide during most of the sex, showing full bodies and positioning clearly — you always know who’s doing what and how they’re arranged. Some of the best shots are in the bar lounge area, where one girl in a tight bodysuit gives a handjob under the table while another watches, waiting her turn.
