A/N: Because I'm so nice, I'm gonna give you guys the M chapter as well. I've never written a sex scene before, so bear with me.
Dean landed on top of the angel, both sets of clothing forgotten on the floor as his lips ravaged Castiel's body. He started at his lips, then trailed down his neck, his chest, resting a moment on the nipples. Castiel inhaled sharply at the sensation washing over his vessel. They had barely started and he could already feel himself on the verge of coming at the hunter's delicate touch. Dean's tongue continued down the length of the heavenly body beneath him - every pun intended. He took his time, though. True, it was fun to tease the poor angel as he waited for Dean to take him, but Dean really wanted this moment to last. He was half afraid that this was all just a dream, so he wanted to savor every second - just in case.
"Dean...Dea..." was the only thing Castiel managed to coherently say as Dean began stroking the side of his member, causing pre-cum to leak out. Dean only smiled as he coated his fingers with some lube - Gabriel thought of everything when it came to playing Cupid - and pushed two fingers through Castiel's back entrance. Cas' eyes rolled backwards, his vessel jolting with orgasmic pleasure as he felt Dean moving inside of him. He finally understood why humans craved this particular activity so much; damn it all to Hell it was exhilarating.
"AHHHHHHHH GABRIEL WHAT THE HELL!?" A traumatized Sam screamed from upstairs. The two paused on the bed, wondering if Gabriel had done something to him. Cas looked up, noticing that lube wasn't the only thing Gabriel had planted in the room. He used his Grace to shatter the camera in the corner into a million pieces.
"Aww, man." said a disappointed Archangel.
"Now that there will be no interruptions," he turned back to Dean, "I do not find it funny to be teased. Let's see how you feel about it." He flipped his body so that Dean was beneath him. The hunter found himself too overcome by the hotness of his fierce sex hair to object. He then followed Dean's methods; he ran his tongue along the hunter, his erection showing the action's effectiveness. He then coated his hand with the lube and wrapped it around Dean's arousal.
"Cas, hurry, I - shit, I can't hold."
He tilted his head, but not in the way he usually did when he was confused by a strange comment (How could Dean be Luke's mother, anyway? There were so many complications with such a thing.). No, this time it was with a mischievous gleam in his blue eyes. "You should have thought of that before you kept an Angel waiting." He moved his hand slowly back and forth, wanting to have the full attention of Dean's lower brain. Dean moaned loudly, loudly enough that poor Sam now required bleach for his ears as well. Bobby was smarter; he had abandoned the house as soon as Gabriel had locked the two in the panic room.
Cas leaned down, not losing pace, to lower his lips to Dean's ear. "Soon, Dean" was all he said. Although Dean was on the verge of coming, he held. Cas simply held his lips in a long, slow, passionate kiss. He then speed his motions slightly, the sudden change of speed throwing Dean into orgasm.
They both came; Cas being a former virgin not needing as much as Dean to finish. Cas flung himself beside Dean, both men breathing heavily as they recomposed themselves.
"That..." breathed Dean, "was the best sex I've ever had..."
Cas didn't reply, opting to pull a book out from under them. Apparently, it had been beneath them the whole time without their notice.
"Ain't that Bobby's?" asked Dean.
"I'm not so sure he wants it now." Cas replied as he tossed the book on the floor. He laid back down and wrapped an arm around Dean, while said hunter curled in toward him.
"Well damn," Gabriel exclaimed, "We should do match making more often, Sammy."
Sam turned slightly green. "Not for a while. Seriously, man, camera's? That's my brother, you know."
"So?"
"So when a sibling, or anyone for that matter are... doing that, you don't plant a camera to watch it live."
"Whatever. You better go tell Bobby that his book's ruined."
"Why?"
"Because it may have somehow ended up in the bed" said Gabriel the ever-innocent one.
"GABE!"
Gabriel found himself being forced by a certain Samsquatch to rewrite a tomb about Japanese beast lore.
Ok, this probably pales in comparison to other lemons you've read, but here it is. Hope you enjoyed! Peace out. \\ /
