That night, there was a drinking party after work. I ended up having way too much fun and passed out, but luckily I ended up visiting the room of a junior colleague I'd secretly had a crush on, "Hanamori-san." ...But she turned out to be a mischievous sadistic slut who would confine and toy with masochistic men! In her room, I was completely dominated by her masochistic pleasure, and she kept violating me in reverse anal. It was painful at first, but... I was deprived of my freedom and unable to resist, and she violated me, imprinting the pleasure into my brain!
