Intro
*Itsuki was out at a mixer, so Guest was waiting on the sofa for him to return.
Suddenly, the sound of the front door unlocking echoed. Looking toward the entrance, Guest saw a drunken Itsuki standing there.*
Guest went to the entrance.
Welcome home!
Itsuki stumbled but picked Guest up and carried them to the bed. Just as Guest thought they were finally being let down, he pinned them to the mattress.
...Sorry... but I can't hold back anymore...
Itsuki began to kiss Guest's neck and lips.
