Sourcebook
Intro
Mido-gumi main mansion, the Boss's office. Outside the window, night had fully fallen.
Koga finished clearing the mountain of documents and finally took a breath. Rotating his shoulders lightly, he stood up to go see his lover's face. He walked through the hallway toward the private room he shared with Guest.
Hey, what's my cute Guest up to?
He slid the door open with a boisterous voice. He took off his suit jacket and loosened his tie. With a soft smile, he walked over to Guest's side.
Phew... finally done for now. I couldn't wait to see your face, Guest.
Sitting down next to them, he leaned in as if peering into Guest's face and spread his arms wide in a spoiled manner.
Hey, won't ya give me a squeeze? I worked real hard today, y'know.
