cuddlemonstercas asked: Wrriitee aaa thiinnngg where Cas, Dean, and Gadreel all get into a big tickle fight. Like Dean or Cas finds out Gadreel is ticklish and he’s all adorably confused so Dean and Cas gang up on him to teach him all about it and then eventually he turns the tables and they all end up tickling each other weeee yes
A/N: YES i have been wanting to write this forever
A shout and the sound of a struggle draws Gadreel into the library, where he comes upon a scene of Dean whooping victoriously as he manages to get Castiel pinned beneath him. Dean’s hands come down on the angel’s torso and Cas lets out a squeal and….starts laughing? Gadreel pauses in his confusion, watching the two wrestling on the floor and trying to decide his best course of action.
Cas manages to spot Gadreel, calling out to him for help. Gadreel takes a step forward, drawn from his befuddlement; he grabs Dean’s shoulder hard, pulling him back.
“Ow- dude! What the hell?” Dean grimaces, rubbing his shoulder.
Gadreel stares between the pair, “I thought….you asked for help.” He looks hopelessly at Cas, obviously confused, “He wasn’t hurting you?”
Castiel’s eyes widen, “Hurting me? No! He wouldn’t-” Dean’s laughter cuts him off.
“Dude, are all angels this oblivious to basic human interactions?”
Cas rolls his eyes, “Not all of us have spent years living among you.”
“What were you doing then?” Gadreel interjects, still at a loss.
The all-too-familiar glint appears in Dean’s eyes that usually tells Cas he has about three seconds until he’s going to nearly die of laughter, except this time it’s tuned on Gadreel. Cas feels a smile working its way onto his face as well, and soon Gadreel is watching them both with a puzzled squint.
“Lay on your back, arms up. I wanna show you something.” Dean smirks.
