"So, what," Dean says, looking down at his burger as the cute blond waitress places it in front of him, "You just happen to know he likes the cosmos at this place?"

"This place is a nexus for human reproduction," Castiel corrects. He's scanning the room and knows the Cupid will be here, but he's having a hard time focusing. He can smell Dean's burger and it's making his mouth salivate. That, and Sam's knee keeps bumping him under the table and sending warm tingles up his leg and to his spine. "It's exactly the kind of garden that Cupid would come to – " he's staring at Dean's burger and the excess amounts of ketchup, would keep staring but Sam bumps him again and this time his leg stays pressed against his own, "-to pollinate."

Sam looks at him, something in his eyes that Castiel doesn't recognize but before he can put much thought in it, Dean's pushed his burger away and Sam's giving him his pouty face. The burger is taunting him, Castiel knows it, and he stares at it.

"Wait a minute," Sam says, incredulous, and Dean looks at him confused. "You're not hungry."

"No," Dean replies, and Sam just can't help but to stare at him. "What? I'm not hungry."

Sam might have the patented bitch face, but Dean can sound just as pissy when he wants to. Like right now, when Sam's hounding him with silent disbelief and concern.

"Then you're not going to finish that?" Castiel asks, startling Sam and Dean from continuing their fight. He doesn't wait for a reply before stealing the plate, and the brothers stare at him.

"Help yourself," Dean says, watching Castiel attempt to devour the burger in as few bites as possible. He looks to Sam, who just shrugs, before he shakes his head and sighs. "How long are we going to have to wait for him?"

"No idea," Castiel says around a mouthful of food. It's disgusting and Dean feels like he's supposed to yell at him, but he's not one for playing Mom so he just ignores it. "This is good."

"Wouldn't know," Dean replies wryly, resting his chin in his palm and glancing over towards the cute waitress. Sam takes Dean's distraction as a chance to rest his hand on Castiel's thigh and the angel startles bad, jarring the table and choking on his burger. "Jesus Christ, Cas, you gotta chew!"

Castiel swallows, almost painfully, his cheeks flushed. Dean must assume it's from his "near-death experience", because he doesn't comment. Sam's hand is hot where it's pressed against Castiel's leg and when he decides Castiel isn't going to push him away; he moves his hand closer to the angel's groin. His breath catches in his throat, and he stares at Sam with wide, confused eyes when he starts tracing his fingers slowly up and down the seam of his slacks.

"So, Cupids, huh?" Sam asks. He flashes a discreet, knowing smile to Castiel and even Castiel's not naïve enough to miss the lust in his eyes. Sam squeezes Castiel's thigh before kneading the flesh and Castiel shoves fries in his mouth to keep from making a sound. "That seems a little cliché for the time of year."

"No kidding," Dean snorts, shaking his head. "It's like something out of a bad thriller movie. The only thing we're missing is David Boreanaz."

"I can't believe you just made that reference," Sam snorts, shaking his head. His hand slips farther up until his palm is pressed flush against Castiel's cock and he smirks when he feels how hard Castiel is.

Castiel can't shove fries in his mouth fast enough.

"Are you feeling okay, Cas?" Dean asks, frowning.

Castiel nods and continues to shove the last of the fries in his mouth.

"Right, whatever." Dean says, rubbing his eyes. "I'm going to hit the head."

"Right," Sam repeats, watching Dean leave before picking at his own dinner absentmindedly. He flashes a lecherous smile at Castiel, who shifts uncomfortably.

"What are you doing?" Castiel asks, his voice even lower than usual, and he doesn't like the way the gravely tone seems to inspire Sam even more. He doesn't stop Sam from squeezing and he doesn't catch the low moan before it leaves his throat.

"You can always tell me to stop," Sam replies in a low, husky tone. And hell, if Sam's going to talk like that, Castiel is incapable of telling him to stop. "Do you want me to stop?"

Castiel is startled by the question, and he shakes his head 'no'.

"So relax."

Castiel doesn't know how to relax. He stares at Sam with wide eyes when the taller male loosens his belt and pops the button on his slacks. He wants to say something, knows he probably should, but he doesn't know what to. Castiel grips the edge of the table until his knuckles turn white.

Sam tugs Castiel's zipper down and slips his hand into Castiel's briefs, curling his fingers around the angel's cock.

Castiel bites back another moan and clenches the table even harder.

If it was anyone else, they probably wouldn't have time for this, but Dean's already told Sam about Castiel being a virgin. He's counting on that fact, and he inches closer to Castiel pressing their legs completely flush together as he starts stroking.

Castiel stares at him with wide, hazy blue eyes, and Sam watches the way he keeps clenching and unclenching his jaw in order to stop from making a sound.

And wouldn't that be terribly awkward, if they got caught because of Castiel's trembling moans? Sam knows they aren't being very discreet, knows Dean could come back any second now, but he can't bring himself to care. Not with the way Castiel is rocking into his fist, tongue barely visible between his lips as he bites down on it, his breath ragged and thighs clenching.

Sam strokes faster, squeezes harder and Castiel is practically doubled over when Sam thumbs his slit and he comes all over Sam's hand, a pathetic sob caught in his throat. Sam wipes his hand on his napkin, watching as the angel struggles to catch his breath. It's now when Dean makes his way back from the bathroom, and Sam believes there must be a God, because his timing couldn't be better.

"You okay, Cas?" Dean asks, sounding genuinely worried. "It's like a freaking ladies room in there, by the way, a guy shouldn't have to wait in line to pee."

Castiel nods his head tentatively and doesn't quite make eye contact with Dean as he does so. Sam claps him on the back roughly, which causes the angel to glare. Sam smiles, as innocently as he can and says, "You really shouldn't eat that fast, man. Or learn to chew. Whichever."

There's a retort on his tongue, but Castiel bites it. He can blame Sam for all of this, but that would be so awkward to admit in front of Dean and he doesn't think he'd ever be allowed around Sam again. Even if all of this is Sam's fault. Which reminds him, his pants are undone, and he has to fix that discreetly, glaring at Sam while he does so.

There's a flutter overhead though, something Castiel can feel even if he can't see, and his eyes flick up and around the room. "He's here," He says, and the brothers stare at him. The Cupid. The entire reason they were here.

"Where?" Sam asks and it's like someone has flipped a switch in his brain. He's all business now, and Castiel really appreciates that. "I don't see anything."

Castiel's eyes are scanning the room, the ceiling, searching for a discrepancy and the brothers watch him closely. "There," Castiel finally says, nodding towards a man and a woman as they start to make out.

"You mean same side of the booth couple over there?" Dean asks, following Castiel's gaze.

"Meet me in the back," He says, and he's gone before either Sam or Dean can say anything. He's going to capture the Cupid, stop him, but a smaller part of him knows he's just using this as an excuse to get away from Sam.
