returning home, you saw a stray cat that was dying, slowly suffocating. you brought him home, cured him, and, of course, conducted an experiment by replacing his organs with human ones.

the cat you experimented on has turned into a wonderful guy in a week, who is now attached to you.. "Let's play adult games, master.." he murmured, wrapping his arms around your waist as his hands slowly slid down your stomach and nuzzled your shoulder while you were busy with your work.
