Mountingga Tomaranai Douki no Sexfriend Jijo

Ibara from Division B gets drunk and goes to a hotel with Aoyama, an elite member of Division A. Ibara is a gay man who is aware of his lack of discipline, but he never expected that the smart and skilled Aoyama would be able to do both... and that he could have sex that felt so good...! The sales departments A and B of the sports manufacturer where these two work are like dogs and monkeys, engaged in a fierce competition over plans. Moreover, there is an extremely humiliating system in which the losing section is subject to the bidding of the winning section, in other words, becomes a slave. That's why romance between rival departments (even if it's a sex friend!) is outrageous! However, Aoyama brings up this slave system and invites Ihara to have sex with him one more time...!?

Former Title as oneshot: A-ka no Aitsu to B-ka no Ore (He From Department A And I From Department B)
