Kare ni wa Ienai Chijoku no Kankei ~Gomenne, Watashi Sensei no Mono ni Sarechatta...~

Morning on the station platform. Amid the hustle and bustle Akihisa hunts his prey.
He's a schoolteacher, but it's the commute to school where he can be his true self:
a predator with a keen eye for vulnerable girls, for future exploitation.

Recently Akihisa -- or Mr. Sasaki to his students -- set his sights on a particular girl.
Today he's going to grope her again, mindful of the fact she's involved with a boy.
In fact he resents their relationship. Both of them are in Akihisa's homeroom class.

Anger and jealousy are the spice that make this cuckolding so delicious.

Sumire has nowhere to run, nowhere to hide her virginity from rape demon Sasaki...!!
