FSDSS-220 Watching my proud big-breasted girlfriend completely fall for the stalking and brainwashing NTR of a sadistic manager, I get an erection in the twilight. Sarara Kamiki

Sara, who became the sex slave of a clingy department head in exchange for overlooking her boyfriend's minor mistakes at the same company. She is brainwashed by her boss, whom she hates on a physiological level, and turns into a big-breasted office lady who undergoes erotic training regardless of whether she is at work or not. Her worthless boyfriend watches all this without helping, and worse, gets excited seeing Sara being tormented.
