MOPP-124 — A mischievous nymphomaniac impregnates a man, inducing brain orgasms, female orgasms, and restraint orgasms. - Rie Miyagi

That night, after work, there was a drinking party. It got more fun than I expected, and I drank too much and passed out. Luckily, I ended up going to the room of a junior colleague I'd secretly had a crush on, "Miyagi-san." ...But it turned out she was a mischievous sadist who loved to confine and toy with submissive men! In her room, I was completely dominated by masochistic pleasure and repeatedly anally raped. At first it was painful... but with my freedom taken away and unable to resist, the pleasure was imprinted on my brain!
