Cas looked at him, mouth agape. He couldn't believe Dean was giving himself to him in such a way. Dean and he had only done this one other time and Dean hadn't liked it all that much. Why was he trying it again? He had said he wouldn't want to do it that way again, he liked it more on top anyways.
"Dean, are you sure?" Cas stared at him waiting for the laughing, but nothing came. He truly thought Dean was joking.
"I'm sure Cas, trust me. I want this. Please." He said looking directly into the ocean blue eyes of his favorite angel. He felt so at home right here, and so exposed.
Watching Dean look at him that way made all his blood rush to his rapidly hardening member. He let out a shallow breath, he was nervous, he didn't want to hurt Dean. He wanted nothing more than to please Dean.
"Tell me if I hurt you Dean, please." Castiel was taking unnecessary precautions, but that's just how he was.
"I will Cas, I promise." Dean replied smiling as he raked his short nails down Castiel's chest and stomach. Making the angels dick twitch.
"Dean!" Sam yanked the door open catching sight of Cas on top of Dean, both naked. "Dammit Dean, put something on the door next time." He said slamming the door shut behind him. Dean and Cas heard him muttering profanities to himself all the way back down the hall.
"Well now that the moment is ruined," Dean said. "I want to tell you something."
"What is it Dean? Is something wrong?" The angel immediately got nervous.
"Oh Cas, buddy. It's nothing bad. I just wanted to tell you I love you." Dean said as he looked away.
Dean never told anyone how he felt, he never hinted at his feelings or showed his soft side. Cas immediately knew he'd meant it, he wouldn't bother saying it if he didn't. Cas looked down at Dean and smiled wide.
Cas leaned down capturing Dean's plump lips and kissing them deeply, and with everything he had. When they broke apart, gasping for air they couldn't stop looking into one another's eyes.
"I love you too, Dean." Dean smiled as Castiel said those three small little words. He leaned up kissing his boyfriend once more. "But Dean, I regret to inform you that I must return to heaven immediately, I've been gone longer than initially planned and my brothers and sisters have more than likely noticed my absence."
"Oh, okay Cas. Please come back soon." When Cas looked into Dean's eyes he could see the pain.
"I will," and with that Dean's face brightened up marginally.
"Good, now get out. Go, go shoo." Dean looked excited which perplexed the angel, but he listened. He zapped his and Dean's clothes back on before kissing Dean once more and flying off.
Once Dean was sure Cas was gone he flung his bedroom door open running down the hall. "Sammy!" He called as he ran. "Sammy where are you!?" He stopped to listen, faintly hearing Sam calling back from the study.
He ran, seeing Sam buried in one of the many books filling this large room. "What Dean? Haven't I been through enough today?"
"Sammy, I need your help," Dean wounded desperate and confused, making Sam looked up, and into his elder brothers candy apple green eyes.
"What is it Dean?" Sam asked watching his brother closely.
"I want you help with something." Dean said shyly, a blush rising to his face. He looked back up towards Sam as he said, "I want to propose to Cas."
