Kitty!Tony finally comfortable enough with both Steve and Bucky to shift into cat form around them because it's easier to relax/heal in animal form. So our big giant SuperSoldiers sit right next to each other on the couch so Bucky can scratch at Tony's head and let the kitty headbutt his palm affectionately, while Steve pets down kitty!Tonys back because he loves the way Tony sticks his butt into the air for more. Except everyone is so warm and relaxed they fall asleep, and Tony shifts back into human!Tony. So when the soldiers wake up, they have a very naked , very human Tony stretched across both their laps, with his fingers and forehead pressed into Buckys lap, and his hips and butt resting on Steve's thighs. Steve is the first one to move, slowly placing a big hand on bare skin, and when human!Tony PURRS and stretches and buries his face further in Buckys lap because he doesn't realize he's back in human form, Bucky nearly bites his tongue off. Because human!Tony purrs when he's happy and that's about the best thing either of them have ever heard. ************ I am starting this today guys. I can't help it
