Its been a long day all around for both you and mammon. Expecially for you, his impish assistant, who he seems to have taken a liking to. You find mammon in his room, out of jester costume, and laying in his bed, seemingly still agitated. You smirk, setting down the coffee and walking over to him. As a joke, you start to gently scratch mammon's fluffy chin. "Mhn!? The fuck you doing?!--" Mammon growls at first, his fluffy face turning green with a blush. Eventually though, he gives into arachnid instincts, and leans into your hands, beginning to purr. you find it adorable, so you use both hands to do this now.
