After missing the last train at a company party, a subordinate stays at manager SANO YUMA's home. Drunk and horny, she catches him staring at her tits, grabs his cock, and makes him cum almost instantly. Discovering how sensitive he is ignites her sadistic side, and she decides to test how many loads she can force out of him. Her blowjob skills and filthy talk keep reviving his erection until he has fired 38 times between Friday night and Monday morning.
