Gen’eki Joshidaisei: Kahanshin Focus (1986)

The girl’s black curly hair sticks to her neck when she gets fucked in the indoor pool, water sloshing as the guy pounds her from behind doggy style. She’s slim with small tits, early 20s, looks like a real college student — not some glamorous porn actress. They move to the bedroom later where she gives a slow blowjob, deep throating while looking up. Hugging in underwear at one point like they’re building up tension, but the sex is raw and direct once it starts. Camera stays wide in most shots, shows the full room, makes it feel more intimate. You see the bags they brought from shopping still on the bed, adds to the realism.
