A/N You're really not missing much if you skip any part of this. It'll be mentioned again in a couple chapters, but you'll survive without reading it.

You know how most people judge their entire day by how it starts? Like, no matter what happens later, it's that initial mindset that really makes or breaks it. It would take a lot to change your mind after the initial jump.

So Dean better have a lot planned today, because waking up to a nightmare is not how he wanted to start his birthday.

Castiel sits up and rubs the sleep from his eyes. God, what a wake up call. He puts a hand on his chest, waiting until his heart rate slows before he does anything. He looks over at his fiancé, sure he accidentally woke him up — every nightmare does — but Dean doesn't move, just lying facedown into his pillow, the arm that had been wrapper around Castiel dropped effortlessly on the mattress. Maybe he did sleep through it today. That's a nice thought.

Castiel can't help but wonder when Dean went to bed last night. He said he would "in a few minutes," but Castiel doesn't even remember the boy coming at all. Castiel doesn't even know what he was doing last night. He'll have to ask later.

Castiel takes Dean's stillness as a sign that he's still asleep, and he slides out of bed as quietly as possible. He'll just throw on some clean clothes and sneak into the living room, let Dean sleep a little bit longer.

The bed creaks as Castiel stands up, and he pauses, glancing back at his fiancé. Dean rolls over and faces the boy, who's sure he's going to open his eyes open, but thankfully, Dean seems to still be asleep. Castiel lets his eyes linger a little longer than necessary on the boy's body. He must have gotten hot last night, because he's just wearing a pair of boxers, and he looks hot as ever.

Castiel grabs the first pieces of clothing he can find and puts them down on the dresser, his back to the bed as he pulls off his shirt and tosses it on the floor by the door, then does the same with his pants and boxers. He's just about to put his new underwear on when...

"Have I ever told you that you have a great ass?"

Castiel whips around at the sound of Dean's voice, his heart pounding. "God, Dean, don't scare me like that!" No warning, no nothing. The whole world seems dead silent, then poof, Dean's talking. He was not prepared for that today.

Dean pushes himself into a seated position and runs a hand through his hair absentmindedly as he looks at his boyfriend in silence for a moment. Finally, he says, "Can you just stand there like that all day so I can admire this art?"

Castiel glances down at himself, and only then does he remember that he's still naked. He feels his face flush and he covers his crotch instinctively. He's about to haphazardly throw his clothes on just so he's covered, but the small bulge in Dean's boxers gives him a strange boost of confidence. Maybe it's because he's so drunk on sleep deprivation that he can't think straight. Maybe it's because Dean seems turned on already. Who knows? But something makes him decide to have a little fun.

Castiel "accidentally" drops his boxers on the floor, his exaggerated "oops" making it clear he meant it. He turns around, his back to his fiancé, and bends over to pick them up.

"Mm, Cas," Dean hums. "Get that perky little ass of yours over here, will you?"

Castiel walks up to the bed, and Dean smirks, already reaching over to him to have some fun. At the last second, Castiel steps back into his boxers, much to Dean's dismay.

"Oh, you little tease," Dean murmurs.

Dean pulls him in by the hips, and Castiel sits on his lip, straddling him. Their lips meet, and the kiss is strong, passionate, and Castiel can't get enough of it. He can feel the bulge growing in his fiancé's boxers, and if he could just get a look —

But Dean wraps his arms around the boy and lies down, pulling Castiel on top of him. Castiel presses his arms down on either side of him, almost caging Dean in, but he clearly doesn't mind. Dean's hands glide along his back, then slip under his waistband and land on his ass. Castiel doesn't think anything of it at first. Hell, he's really freaking turned on, just lying on top of the boy like this, nothing between them. But then he feels Dean's finger getting closer to his hole, and he's read enough shitty wattpad fan fiction in his life to know where that's going.

"Dean —" Castiel pushes himself off his fiancé, sitting at the edge of the bed.

"Ah, come on, Cas," Dean whines, somehow even making that sound sexy.

"I'm sorry, I just — I don't really feel comfortable having sex right now," Castiel mumbles, spitting the words out quickly, like it's poison on his tongue.

"Come on, Cas, after all that?" Dean sits up and reaches to take his hand, but Castiel quickly moves both hands behind his back in what he hopes is a subtle movement. Dean sighs. "You can't just tease me like this, Cas. You gotta give me something."

Castiel bites his lip. "I'm sorry, I just..."

"Please?" Dean asks. "Cas, you — this —" He gestures to Castiel's almost naked body. "It's driving me wild, Cas. Just give me something. Anything."

"Dean —" Castiel's about to protest, but it occurs to him that he could actually have a little fun with this, and still get out fine. "How anything are we talking?"

Dean must hear it in his tone that he has something in mind, because he smirks. "How anything are you willing to get?"

Castiel kneels on the end of the bed, his legs spread, and pulls down his boxers just enough to show an inch of his dick. Before Dean can move any closer, Castiel covers it up again, putting the same hand up to stop him.

"Ah, no touching the merchandise, Dean," Castiel says with a playful smirk.

"But —"

"Or, you know, I could just go get dressed, end this now," Castiel continues, and he already knows Dean isn't going to go for that.

"Okay, okay, no touching," Dean concedes. "So, what's the game?"

"The 'game' is whatever you want it to be, Dean," Castiel tells him. "You can get off however you want — but you gotta keep your hands off, or I'm ending it right there. Sound like a plan?"

"Well, I'll take it," Dean says.

"I know you will," Castiel says.

He hooks his thumbs in his waistband again, and Dean puts a hand down his boxers, already rubbing his dick.

"You know," Castiel drawls, deciding to add just a little more fun for himself, "I don't think it's fair that you get to see me without these on twice, but you've been wearing those all day." He crawls on his hands and knees across the bed and hooks a finger under Dean's waistband instead, purposely touching just a little more skin than necessary.

"But I thought —"

"Ah, I can touch you however I want," Castiel says, his finger gliding over Dean's cock just to prove his point. "You just can't touch me."

"Well, that's just not fair," Dean pouts.

"All's fair in love and war, Dean," Castiel murmurs. He pulls the front of Dean's boxers down just enough to pull his dick out and licks his lips. "Now that's what I wanted to see first thing in the morning." He bends down like he's about to suck it, but instead just kisses the tip before pulling back, kneeling at the other end of the bed again.

"God, you are such a tease," Dean mutters.

"Oh, don't I know it," Castiel says. He's actually a bit grateful Dean saw it as a tease, because he was really hoping he'd be able to get away with not actually knowing how to give a blowjob.

Castiel hooks his thumbs under his waistband again, which is Dean's cue to start jerking off again. Castiel pulls his boxers down below his butt, his dick out in the open again. Dean lets out a small moan, though whether it's because he likes the view or because he's enjoying himself, Castiel isn't sure.

Castiel wraps his hand around his own dick, sliding it up and down slowly. It occurs to him that he could do the same thing as Dean, but isn't it awkward, masturbating in front of someone else? Instead, Castiel sits down, sliding his boxers all the way off and tossing them carelessly on the floor. He crawls over to Dean, sitting right in front of him, probably unbearably close for his fiancé.

Castiel brushes his hand against Dean's inner thigh and he moans, hand sliding up and down even faster. Castiel smirks and squeezes his thigh lightly, causing Dean's head to loll back. Dean tries to reach for him with his free hand, but Castiel catches it before he does.

"Ah ah ah, no touching," Castiel purrs, putting Dean's hand back down by his side. He bends over, sticking his butt up in the air as he presses kisses to the insides of Dean's thighs.

"God, I'd love to smack that ass," Dean murmurs.

"You mean this ass?" Castiel turns around on his hands and knees, sticking his ass right at him. He backs up, closing the distance between them. "This ass right here?"

"God, you fucking tease," Dean moans.

"Mm, I am, aren't I?" Castiel agrees, turning back around to face him. He takes his dick in his hand, rubbing it slowly.

Dean doesn't take his eyes off it, his own hand speeding up, and between the moans, he manages to get out, "I'm gonna cum, I'm gonna —"

And he does, which is much more satisfying than Castiel would have expected. He watches with a smirk as Dean has his moment, and after a brief moment to recover, he seems more than willing to share.

"You know," Dean says, "if you want someone to finish you off —"

"No, what I want is for you to go take a shower," Castiel says teasingly.

"Care to join me?" Dean asks.

Castiel chuckles. "Tempting, but no. I'm gonna pick up all the clothes on the floor instead. You made such a mess today, Dean. You should be ashamed of yourself."

Dean slides off the end of the bed and presses a kiss to Castiel's cheek. "But I'm really, really not."

Castiel smiles to himself and gets out of bed, bending down to pick his boxers up off the floor.

As Dean walks by, he says, "And after all that, I'm still right. You do have a great ass."
