Stressed from work, I went to M-Sensation for some relief, only to find that the girl I called was actually my plain coworker, Kasui! She whispered dirty words in my ear while I waited for her, bound and pathetic. She kicked my ass with her boots, stepped on me, and slapped my cock! Hearing my involuntary whimpers only accelerated the play! She pounded me with a jackhammering cowgirl position! With my weakness exposed, I couldn't even look her in the eye at the office, forced to give her hush-money blowjobs! We even had full-naked shame play at the desk at night! It's frustrating, but her sadistic play feels too good—I came over 20 times! I can't get enough of being looked down upon by Lady Kasui with those cold, low-blood-pressure eyes!
