Our Naughty Business Trip, Woking Overtime On My Colleague's Butt

Akio is an elite sales rep, but he can't stand his coworker Fuyuno who is picky about everything. Their work styles and personalities are complete opposites. One day, they get sent off on a business trip together. What's more, they have to sleep in the same room! Felling low about having to spend the night together, Akio returns to the room after having cooled off outside for a bit. He opens the door and hears a strange noise in the back of the room and when he takes a peek, to his surprise, he finds Fuyuno in the middle of enjoying himself. One thing leads to another and before he knows it, Akio becomes fond of Fuyuno. Even after the trip he realizes he wants to play with him again, but it won't be so easy to convince Fuyuno...
