START-402 | After a drinking party, I ended up having a one-night stand with a colleague I don't really like, and my dick fit so well into the depths of her vagina that I ended up experiencing the greatest orgasm of my life... Even though I didn't like her at all, I ended up having sex with her again and again, Honjo Suzu

Co-workers Suzu and Yuya have completely opposite work styles and are uncomfortable around each other. One night, Suzu misses the last train after a business dinner with a client and is forced to stay the night at Yuya's house, who is also there. As the two of them drink, the conversation turns from work to dirty talk... and as they get worked up and start to insult each other, something unexpected happens: "If you say so, why don't you try it!?"
