Stressed from work, I went to M-Sex for relief, only to find the girl I called was my plain coworker, Kasui! She whispered dirty words in my ear while I waited for her, pathetic and bound! She kicked my ass with her boots, stepped on me, and slapped my cock! Hearing my involuntary screams made the play accelerate! Piston-fucking cowgirl! With my weakness exposed, I can't even look her in the eye at work and have to give her hush-money blowjobs! Full-naked shame play at the desk at night! It's frustrating, but her sadistic play feels too good, leading to over 20 ejaculations! I can't get enough of being looked down upon by Lady Kasui with those cold, low-blood-pressure eyes!
