Mixture of very horny and sexualized jokes toned by the fact that almost all characters are underage. Despite that, you got blowjob training, endless hunt to lose virginity, methods of renaming your poor sexual life to locked achievements, sex robots and interstellar visitors.
It's Douman Seiman, so you either love the art style or hate it all together.
Most characters are high school students and those are ranging from horny sisters, lesbians club with one poisonous-body-like-plant-girl to flasher, depressed guy and his sex bot and an alien.
Ok to read if you got an hour or so to wait and want some giggle or few chuckles but in the end it's really tiring to only get jokes about anal, scat, bj's while most of the jokes are drier then Sahara Desert itself.
