Yakuza-sama no Omocha dj - Koyoi wa Tengoku

One night after work, Yuuya's colleagues treat him to an evening of drinks for a job well done on a difficult project. On the way home, while it's obvious that Yuuya's drunken a bit too much... he is in a really great mood. Not wanting the night to end, he heads over to Kurose's place with a present of booze in hand. With Yuuya high in spirits, and Kurose finding his inebriated state so very cute, Kurose also ends up drinking too much. As per usual for the two, they get nice and intimate and... you can guess what happens next!
