That's Impossible

Chapter 7

Cas tilts his head in confusion as Dean starts squirming. "May I ask why you called me here?" Cas asks as he straightens his head. "Um, accident?" Deans tries to state it, but it comes out as a question. Cas hums his acknowledgement and nods his head. He then leans over and puts his hands on either side of Dean's leg. Dean's breath catches as the angel slowly starts crawling up the bed. The room is suddenly boiling hot and stuffy and Dean can't breathe and he's trying not to hyperventilate. 

"Are you sure it was an...accident?" 

Dean had never heard Cas' voice so low and before he can help it, he groans. The angel just smirks. "Cas..." he practically breathes the angel's name. "Cas, wait. Cas, stop." Dean holds his hands up, but the angel is already up to his hips and is straddling him. Cas sighs, and sits. Dean guesses the angel doesn't know he's still affecting him by sitting in his lap. 

"Dean, what is in your pocket?" Dean blushes hardcore as the angel squints his eyes and begins to investigate his crotch. "Forget about that." Dean says fastly and grabs the angel's wrists. "Why are you doing this?" Dean asks. Cas opens his mouth to answer, but he must not have one because he quickly shuts it and furrows his brow. "I. I don't know, Dean." 

Dean just stares as the angel bows his head but continues, "I only feel at peace in your presence. I've no experience with human emotion, but I seek happiness and pleasure." Dean's cheeks redden furiously at the angel's bluntness. He lets go of Cas' wrists. "However, I know that I only want it from you. I can only have it with you." Cas raises his head to look at Dean, most likely to gauge his reaction. 

Dean opens and closes his mouth a few times before breathing in, "I don't want to mess this up Cas. You're my friend. You're practically family. I can't, no, I won't do this." Dean meets the blue-eyed gaze and isn't prepared for what happens next. 

Cas grabs Dean's face and rests their foreheads against one another. "Please, Dean." Cas' voice is a broken whisper. "I'll do anything." He pulls away slightly so Dean can look into his eyes. "I am begging you." Dean sucks in a breath and shuts his eyes, and before he can answer he feels the angel moving. His eyes open to the angel grinding down on his lap, and Dean, well, Dean loses it. 

He grabs a handful of trench coat and pulls Cas to him. "Castiel," the angel is shocked at his full name coming from those lips just a couple of inches away, "Don't leave me." A ghost of a smile appears on the angel's face, "Never." Dean knew Cas had sincerely been begging. At that moment, Cas was at his weakest. He was so vulnerable that his wings became uncloaked and shadowed the entire room leaving Dean speechless.
