My boss, Sumire Mizukawa, is beautiful and capable at her job. But... her true face is a true 'SM Queen'! She noticed me, her subordinate who is nearby, at a time when she was looking for a man she could dominate! I was invited on a date called M-man training, and she torments me with a reward creampie as bait! Devilish service training, continuous ejaculation endurance, and repeated edge-of-orgasm ejaculation management! Sumire-san, who torments me with a happy face, is scary, but I wonder if I'm a perverted useless dog because my dick gets rock hard...?
