18+ Boku dake no Bitch

It's been years since Taichi's childhood friend Erena last came to his house, until one day, Taichi finds her sitting in his room, asking him to have sex with her. Unhinged by her offer, Taichi refuses her advances, believing that a proper girl needs to be pure and take care of her appearance, unlike Erena who behaves and dresses like a slut.

Ignoring him, Erena decides to take advantage of Taichi's one weakness: big breasts! As she undresses, Taichi is left speechless as his cheeks begin to burn red from Erena's lewd display of her naked body.
