Kotoba Tarazu no Futari

I'm gonna win this time and stop being his fuck buddy..! Kitazawa made a bet with Tsuzuki, and as long as his sales results remain worse than Tsuzuki's, he's stuck as his friend with benefits. And the worst part about it is that he actually enjoys having sex with Tsuzuki, though he hates to admit it. Eager to be free from this troublesome relationship, Kitazawa ends up.. providing sexual favors to an older client..!? But will he finally be able to understand his own feelings?.
