He doesn't show it really, or wants anyone to know. But it's obvious. You see it in the way his breath hitches when Rain compliments him. You see it as twinkle in his eyes when one of the ghoulettes is soft to him.
He absolutely melts whenever he's fucking our little princess Rain and hears how good he is doing. How nice it feels. The pants and moaning being little praises on their own.
And then he hears Aether calling him a good boy. His knees getting weak. Fighting a blush from creeping onto his cheeks. But a caressing hand on his face breaks his walls. He let out a pleased, maybe even needy, sigh.
It dawns on Aether. And he smirks. "You're just so good for me, aren't you? My perfect little troublemaker.."
Swiss thought are filled with I wanna be good for you. So so good. Even though he'd never admit to them out loud.
It leads to some interesting situations. Especially when out of the blue, Rain approaches him. A smile tugging at their lips. "There is my good ghoul." And Swiss immediately heats up. Snapping his head towards them. That reaction is all Rain needs to reverse the roles in their bed for tonight.
Who would've known it was that easy to make the feisty ghoul sink to his knees, a flustered mess?
