A/N I'm writing this in honor of Supernatural day, September 13. I dressed up as FemCas in case anyone wanted to know, Kels was FemDean and our friend was FemSam. –Lyn
"Are you sure?" Castiel asked. He wasn't going to do this if Dean wasn't absolutely positive.
"Cas, don't make me beg." The other man responded. The angel smiled and gave him a quick kiss to the lips.
"Never, love." With that he slammed his dick into Dean. The Winchester gasped and arched his back, his hips lifting off the mattress slightly as he did so. Cas grabbed Dean's hips and slammed into him again, pulling a sharp breath from his lips. Cas sped up and Dean grabbed the sheets in his fists. The angel pulled himself closer and let go with one hand, wrapping it around the small of Dean's back. He hit Dean's prostate with his next stroke.
"Oh God!" Dean shouted. That only fueled Cas's passion and he worked harder toward his peak. Dean came, spattering white, sticky seed over their stomachs and a moment later Cas came as well. He pulled out and lay partially on Dean, partially on his forearm and poured kisses on him. Dean returned them and eventually they both fell asleep.
"Cas? Are you alright? You've been awful quiet." Dean asked a few hours later when they woke. Cas propped himself up on a forearm and frowned.
"Do I not satisfy you?" The angel asked.
"Excuse me?"
"Well I see no other reason for you to shout both my brother's and father's names unless I do not satisfy you and you lust after them instead of me." Dean froze for a second before chuckling and stroking Cas's face with a single finger.
"You know, habits are terribly hard to break." Cas scowled and shifted slightly so he was facing Dean directly.
"So what would you propose I do?" He asked, slightly irritably.
"Well, you could just fuck me until I forget about ever wanting anyone else." Dean suggested with a coy grin. Cas thought for a second before nodding.
"That would probably be the best option. It's certainly the most appealing."
