Oshioki Lesson v1.0 (English, Japanese)

◾︎Synopsis It’s been about half a year since I was assigned to this department. I’m occasionally late or make mistakes, but I feel safe because my senior colleague is there for me!!! We’d always joke around, and I thought we were getting along well at work… That day, too, I was just messing around with my senior colleague and figured I’d just apologize half-heartedly and call it a day. But then, out of nowhere, the days of inescapable “punishment” began. Every time I resisted, I was cornered, and my will to defy him was gradually worn away… Before long, I found myself trembling and able to do nothing but obey my senior’s every word—. From that day on, I became his personal sex slave, used day and night. I’d been reduced to nothing more than a “convenient hole” for him… Days of being treated like a throat sex toy… The office, conference rooms, restrooms, the storage room, izakayas… he didn’t care where. Under my desk, in the conference room, even inside the men’s restroom… my throat is used in whatever position my senior prefers. Even if I gag, even if I can’t breathe and it’s agonizing, he won’t stop… Even if I can’t take it anymore and throw up, far from stopping, he gets angry at me for “making a mess”… Not only does he cum in my mouth and on my face, but he even forces me to drink his stinky, filthy urine… Reduced to a flesh toilet for his sexual gratification… My senior summons me day and night, no matter where I am, to satisfy his sexual urges. In all kinds of positions… he penetrates me without asking for my consent. It doesn’t end with him just cumming inside me… he even forces me to endure the humiliating act of urinating inside my vagina. I have to kneel in a deep bow until my senior is satisfied. He tells me to kneel and apologize… and if I refuse, he stomps on me mercilessly… An apology alone isn’t enough to get his forgiveness—he even makes me lick the floor. It’s disgusting, and I absolutely refuse… But when I refused, he stomped on me hard again,
