[Warabimochi] SHIKOSEN Seiseki Kyouka ni 'Sakusei' ga Sonzai suru Sekai [Kuraudo] [Full Color]

In a world where 'semen extraction' is a mandatory part of the school curriculum, one bratty student thinks he's hit the jackpot when he gets to mount his gorgeous teacher from behind, calling her Maina right to her face while he pounds her into the bed. But the smirking 'Wanker Sensei' has discipline planned—by Day Ten she stands over him fully dressed and arms crossed while he trembles and begs to cum, promising she'll squeeze every last drop out of him only once he learns to obey. When the reward finally comes, her smug grin and skilled handjob make it clear who has been running this classroom all along.
