Even the scary yankii girls from my school days have now gotten married and are living as ordinary housewives... or so I thought, but it turns out they were secretly working part-time as lewd masseuses behind their husbands' backs! The former bullied kid who stumbled upon this hidden information, having harbored resentment for being ridiculed during his student days, decides to exact revenge on them! With his newly acquired large penis from a penis enlargement surgery, he summons the former yankii girls to his home, teasing them with his secret, and forces them into rough sex! And even creampies them!
