Ijimekko no Bakunyuu Haha Gachi Haramase Seisai! ~Do S na Onna Shachou Mama o Ero Hidoi Koto de Yorokobu Do M Onaho ni Shite Yatta♪~

The mother of a bully is an arrogant and sadistic CEO bitch!
Use the power of your young and virile d*ck to rain a shower of humiliation
down upon her! Here begins your gapeface inducing, masochistic faphole
rendering NTR counterattack against the bully (and his mother) that injured you!

She may thinks she can cover up her bully son's misdemeanors,
but not if you have any say in the matter. Use the truth to blackmail her!
