“Guys—Gabe,” he pleads to the archangel because Castiel’s too curious about… everything and tends to get too focused to listen to Sam unless he’s in real discomfort. “We—Gabe, this is gonna end too soon if you two—amph—uh…” Sam arches back when Castiel’s lips find that spot behind his ear and kisses the tender place softly before scraping his teeth over it.

“Fuck! Cas!” Sam exclaims loudly, surprised and a little—a little. Sam doesn’t know. Can’t they see that he’s trying to talk and think here?

“We noticed that it’s not just us with the neck fetish, Sammy,” Gabriel smirks against Sam’s racing pulse point, not willing to raise his head from Sam’s neck even to look at Sam while he talks.

“Yeah, OK, so-” he cuts himself off as he feels Castiel move to his right, feels his angel’s lips hover the juncture between his long neck and wide shoulder. Gabriel matches the position on Sam’s left side and they just stay there, hot breath ghosting over the bruised and kissed wet skin of Sam’s neck.

“Too much, come on,” Sam pants, squirming. He’s so… everything between his legs aches so deep it’s good but this fun is going to be over before it starts if he doesn’t—if they don’t—

“Forgot to tell you, Sammy,” Gabriel husks, low and dangerous like a growl.

“Gabriel and I were… interested in something and thought we’d do an experiment,” Castiel finishes, his voice strained with lust and love and both of them so close, so hot and deep even though the only places they’re touching him is his neck with their mouths. Sam can’t help it—he can’t wait any longer—and he starts rocking his hips, groin getting some friction from where he’s pressed against Gabriel’s inner thigh. But Gabriel shifts his leg away, leaving Sam whimpering.

“Don’t ruin our experiment, Sammy,” Gabriel tsks.

“Wha-” Sam breathes brokenly but doesn’t finish because Gabriel and Castiel seem to take heed of some unseen and unheard cue. They both stamp their mouths on Sam’s neck—Gabriel’s tongue fluttering against him and Castiel’s mouth the wider of the two, tongue held back so that this hot void pulls Sam in.

Then they bite down and Sam shouts, cock twitching hard, chest and stomach trembling and convulsing. He reaches to finish himself off but they stop him—he doesn’t know which one. Before he can form the curses that are rolling around his hazy mind they both relent, teeth drawing back leaving behind stinging pain that pings throughout Sam’s body like a lightning bolt.

And then they begin to suck—hard and pushy, demanding something and it feel so… so…

When he comes it surprises him even though he knew how close he was. He bites his lip, shakes his head, and Castiel and Gabriel hold on, licking the bruises and love bites that they’ve left behind lovingly, adoringly. It’s what grounds Sam soon after he loses it—right after it feels like he spirals out into nothing.

When he becomes more coherent he finds himself hunched over and propped up by his lovers’ bodies who are both now using their hands to carress the rest of his body.

“You did so good, baby,” Gabriel whispers.

“Surely you’re the most beautiful of my Father’s creation,” Castiel remarks in awe.

And then, predictably, Gabriel hisses lowly to Castiel. “Dude, no need to bring Dad into this.”

“What… what did you guys do?” Sam pants when he finds his voice which was lost somewhere between perfection and disbelief.

“I think it would be pretty obvious,” Gabriel teases. His shoulder is currently cradling Sam’s forehead so when Gabriel turns to kiss him his lips graze over Sam’s ear, hair, and temple.

“No, that’s not… you were up to something,” Sam huffs, still without the energy to raise his head. All that he knows is that there’s a sticky, drying mess between him and Gabriel and that his lovers are still aroused, though neither of them seem to be in any particular hurry to take care of it. But Sam remembers that they had said something earlier, right before… well, before. He squirms and blushes.

“Told you it’d be over before we started,” Sam pouts because now it’ll take him a while to get ready to go again.

Gabriel chuckles and he feels Castiel lean over him, chest molding to his spine. “You did perfect—and proved exactly what we hypothesized.”

Sam blinks, something clicking in his head. That’s right, they had called this an experiment earlier, whatever the hell that meant…

“We noticed that we’re not the only ones with a neck fetish. It drives you crazy, doesn’t it? Our mouths and teeth and tongues on you,” Gabriel husks out and, God, even just saying that makes Sam’s neck tingles, makes a shudder wrack through his sated body.

“We wanted to know if we could bring you to orgasm with your neck alone,” the other angel murmurs, amusement in his voices as his wandering hands begin to trace idle patterns between his ribs. Sam frowns, not sure if he’s turned on or cranky that they decided to sexually experiment with him. Castiel goes on, “and our experiment conclude that we-“

“—need to conduct further testing,” Gabriel growls, interrupting his brother and lifting Sam’s head with one of his hands. Sam has a moment to take in bright amber eyes before Gabriel consumes his mouth in a rough but lovingly eager kiss. Castiel starts peppering kisses along the back of Sam’s shoulders while his warm, smooth hands run up and down Sam’s thighs and cup the sharp points of his hips, fingers digging into the tender crease between his thighs and groin.

Sam sighs contentedly into Gabriel’s mouth and decides that he’ll let them slide for their little conspiratorial experiment.

Just this one time, though.
