Cas loved when Dean was inside him when he went celestial though. The angel always took precaution and made sure everything was safe before allowing himself to come out of his vessel and show his lover his spectacular wings.
Whenever Dean touched his wings it was a large stride to his finish, he refused to let this end. He wasn't sure when he would see his Winchester again. He looked down at the man below him. Watched as his face contorted with pleasure and his breathing increased slightly, signaling to Cas that he was about to come regardless of Castiel's wishes.
He focused on his body for a moment and let himself concentrate on the feeling on Dean's dick rubbing against his prostate every time he slid back down, he felt as Dean's dick throbbed inside of him. He loved the feeling of Dean filling him.
When Dean reopened his eyes Cas flared his wings. He flared them the way angel's do to one another when they are trying to impress a potential mate. Dean cried out and reached his hands up grasping at Castiel's wings threading his fingers through them and pulling.
Castiel felt Dean pulsing inside of him as he came. He came along side Dean as his boyfriend played with his feathery appendages. He cried out again causing the furniture in the room to vibrate, he looked down at Dean as his come coated his boyfriends chest and stomach.
Once they had both rode out their climax, Castiel returned himself to his vessel before pulling off of Dean, whimpering at the loss. He flopped himself down next to Dean, rolling over onto his side, and propping himself up on his elbows before leaning over to kiss Dean on the lips. Relishing in the feeling of his boyfriends soft lips.
He knew they needed to get cleaned up, but he didn't want to move, he was back in Dean's arms where he felt like he belonged. He looked down at the drying substance covering Dean and smiled. Dean always did this to him, made him feel overly happy about nothing.
He looked up to Dean before placing his fingers on the other man's chest zapping him clean before smiling. He loved it when they were together like this, when it wasn't quick and done. He always felt so much better when they spent some time together.
Although, this time was different, this time Cas had been away for days for the first time since they'd started dating, and he most likely would be again. He knew Dean didn't usually enjoy these heartfelt moments, but he sure did. He loved every minute of being in Dean's arms and felling the man's body heat up against his. He just loved being near Dean
"I missed you, Dean," Cas mumbled as he buried his face into the other man's chest. "I'm aware it was only 4 days," he kept talking as he raised his head to look into Dean's candy apple green eyes. "And I know no 'chick flick moments' I've learned I just-"
He was cut off by being kissed, long, yet soft and full of passion. Dean put what seemed like every ounce of emotion he felt into that kiss. Wordlessly telling Castiel that he felt the same way.
When they finally broke apart, and Castiel looked into Dean's eyes, they were filled with unshed tears. He looked so happy, and for a fleeting moment, the angel wondered if he wasn't the only one in love.
