Aaah, the magic of hentai. See here: a boy is laughed at because it was noticed in class he had a raging boner in his pants, and the girls laughed at him. His pride crushed, he stops coming to school. And so, in an admirable move of human kindness (and not because he probably had a massive tool, you creeps), every girl from his class comes to his house, to comfort him, etcetera ┐(￣ヮ￣)┌
You won’t find me complaining, this is good group sex (9 girls!!), drawn rather well (with the usual idiosyncrasies, perfect heart-shaped bubble-butts, big breasts, smiling girls with a touch of gyaru, and this time today’s special is an hentaiburger), not Marui Maru’s best but still good, with quite tolerable censorship, why refuse to enjoy it ^_^
For more butts, Cf. The list of ALL Marui Maru’s works on Hentairules!
