My boss, Sumire, is beautiful and good at her job. But... behind that facade is a true 'SM queen'! She was looking for a man she could dominate, and she set her sights on me, her subordinate, who was nearby! She invited me on a date called M-man training, and tormented me with the promise of a creampie as a reward! Demonic service training, continuous ejaculation endurance, and repeated edging to manage my ejaculation! I'm scared of Sumire who bullies me with a happy face, but my cock is rock hard, so am I a perverted, useless dog...?
