It's common to see a senior male club member and a female manager walking home together after practice. There are also plenty of impure heterosexual couples secretly fooling around on campus. Since male athletes have twice the sexual drive, it's understandable. This is a fixed-point video capturing the entire scene of a female manager being called to the club room building as usual, unaware she's being secretly filmed, and being devoured by a friendly senior male, moaning in pleasure. The sexual promiscuity of Reiwa-era boys and girls is remarkable, but it might be a saving grace for the declining birthrate, so I'll keep watching.
