Yukino works at an advertising company that she has always dreamed of. When he works overtime with a colleague he hated since he joined the company, he unexpectedly approaches and eventually crosses the line. Even when receiving a call from his fiancée, he is still absorbed in it, so he ignores it. In the office at midnight when there is no one there, it ends multiple times with the colleague's penis. I could have had many opportunities to return to my fiancée... but my sensitive body craved for the colleague. The two impure loves never run dry until morning. The worst betrayal of NTR ever.
