Season 1

The sexual adventures of protagonists no longer occur only in Imaizumin’s small apartment, now the girls also have sex with him inside the school. Because Imaizumin’s mother is coming to visit him, Reina, Yukina and Ruri leave him alone for a few days to receive her, a situation that makes him sad as he feels lonely again.

Imaizumin and girls move into a new apartment that is much bigger and cheaper than the old one. Although his new apartment is perfect, an issue arises when his new neighbor turns out to be Risa, Reina’s older sister, who seduces Imaizumin when the girls are not around.

When it comes to Christmas, it’s gotta be a ski trip! The gals pile into the car driven by Risa and head straight for the ski resort, but even in the backseat, their intense teasing and torment never lets up! After having a blast at the ski slopes, it’s off to the hotel! In a completely different setting—a trip away from home—there’s no way these gals aren’t gonna be in heat… As a result, Imaizumi gets endlessly milked dry in an orgy with all four gals, fucked nonstop until he finally collapses…!?

As usual, Imaizumi was spending his days in sweet, lovey-dovey sex with the gals, but one day, when he and Ruri finally end up alone, she makes him promise her a proper date. Having come to cherish every moment spent with Imaizumi, the second they get back to the apartment, Ruri starts an intensely passionate session of sex so hot their bodies practically melt into each other… Feeling nothing but love, Ruri overlaps their bodies again and again, cumming over and over. But the other gals notice that the two of them are fucking…!?
