With his parents working overseas, Matsu stays at the home of his tsundere childhood friend, Yuki, and her gorgeous mother, Yasuko. While Yasuko is kind and caring, Yuki is a roughhousing dark-skinned kogal prodigy who loves to assert her iron will on Matsu. But it’s not all bad for the young man, because when she has him locked up, he can feel her plump thighs and big bust smash against his body!
After a pretty intense tussle, Yuki catches Matsu’s pitched tent. She then proceeds to laugh at how pathetic he is; claiming the only thing he’ll ever beat her in is his perversion. Matsu calls her bluff and the two start banging, seeing whose grades in bed excel! Yuki needs to watch out though, because they’renot discreet, and others might want to see if Matsu’s up to snuff!
