At a company drinking party, I drank too much and lost all memory of what happened afterward. At some point, I must have passed out, and I had no idea where I was. Suddenly feeling a strange sensation in my lower body, I opened my eyes to find Koharu Asai, a junior colleague who's usually plain and quiet at work, riding on top of me and rocking her hips with obvious pleasure. I tried to cry out in shock, but she didn't stop—her tight, skilled movements kept drawing me in. I nearly blacked out from pleasure, and her insatiable, deep rhythm pushed me past the point of no return.
