“So… Correct me if I’m wrong here, but you did mention that a human and an angel aren’t supposed to…” Dean doesn’t finish his sentence, instead he glances over his shoulder and suggestively wiggles his eyebrows to refer to their earlier activities, gesturing with his finger between himself and Castiel.
Castiel, who’d been reverently tracing the knobs of Dean’s spine, his fingers gliding along freckled skin, rolls his eyes.
“What?” Dean asks as he shifts onto his other side, now facing Castiel and smiling up at him with the toothy grin that might have been part of the reason why Castiel had fallen in love with this infuriating human somewhere along the way. “We just broke the law, Cas! We told Heaven to go screw itself!”
Castiel settles for tracing the freckles on Dean’s chest and collarbones instead; There’s no need for him to even look at Dean’s face in order to see his expression, seeing as the smugness in his voice gives it all away, revealing that he’s not sorry at all.
“In case you need an update on how the male body works, I’m fairly certain that what we did won’t get you pregnant.” Castiel teases, pausing to press a light kiss to Dean’s shoulder. “It may be frowned upon by my brothers and sisters, but we’re not endangering entire worlds. Separating us is far from their priority.”
“Huh… Guess it’s a good thing that I’m not a woman, then.” Dean huffs jokingly, his arms finding their way around Castiel’s waist, pulling him against his chest.
Castiel goes willingly, burying his head in the crook of Dean’s neck. He considers Dean’s words, but smiles to himself as he confidently answers “Even then, or no matter what other circumstances would’ve been different… We would’ve found a way, Dean.”
It’s silent for a moment, and Castiel thinks he feels Dean’s lips, brushing the top of his head.
“Yeah…” Dean mutters eventually, sounding nothing but earnest all of a sudden. “Yeah, we would have.”
At that, Castiel says nothing, merely hums in contentment. It’s good to know that Dean believes in them as much as Castiel does.
