Part 5: the grand finale 🍾
As his double's fingers closed around his straining cock and drew him out of his once-more unfastened fly, John, groaning, palmed Sheppard through his pants in return. His other self was every bit as hard as he was, cock hot and rigid, pressing out against the front of his BDUs.
Sheppard's hips rolled to rut into John's palm, tongue slick and sliding against his own as they panted against one another's mouths. As John started belatedly, distractedly unbuckling his double's belt for him, Sheppard broke the kiss, stubbled jaw scraping against John's cheek.
"Wanna fuck me?" Sheppard grated out the hoarse question by John's ear, hot breath ghosting over his skin. John could feel his other self's grin.
"Fucking hell," John managed, a plaintive grunt escaping him as Sheppard's hand fell still between them. The tip of his cock had ended up under the hem of Sheppard's t-shirt, pressed to his belly in a copious smear of precome.
"C'mon, we both know you want to," Sheppard added, and then he was letting go of John's aching cock completely to yank hastily at his own fly. "Bend me over right here, and don't hold back."
"I'm not gonna last long," John pointed out, already shoving Sheppard's clothes down to his thighs for him.
"Neither am I," Sheppard answered with a breathless laugh-- and then he was bending over, braced against the hopefully-sturdy shelving with one hand while shoving the other into his own crotch.
John spit into his hand, as wet and messy as he could manage, rubbed his saliva hurriedly over his almost-oversensitive cock... And with a step forward, pressed the slippery tip to Sheppard's hole.
His own shaky moan was echoed, slightly muffled, as he pushed steadily in, the heat of Sheppard's body gradually enveloping his cock in tight squeezing pressure. His double pushed back into it with a loud exhale that might have been the words fuck yeah, booted feet as wide as they could get and his hand already pumping hard and fast under him.
Buried to the hilt, John paused there for a brief second to get a grip on Sheppard's bared hips, set his stance... and then drew partway out before slamming back in again with a loud grunt of mingled effort and pleasure and continuing distant shock that he was literally fucking himself.
He didn't hold back, fingers tightening and digging into Sheppard's flesh, his own hips snapping forward again and again, hard and fast as he chased his own orgasm with a desperation verging on frantic. In front of him, Sheppard was in the same state, back arched into it, his arm taut and pumping, and loud panting gasps and grunts spilling incessantly from his lips until John wondered vaguely if there was anyone else around to hear the racket and come bursting in through the door.
Before he managed to worry too much about that, though, John felt his balls pulling in tight, the demanding heat building in his groin abruptly swelling to a peak-- and before he could even choke out a warning, that heat-pressure-pleasure crested and snapped. He jerked on his feet with a ragged and nearly surprised gasp as he came, leaning his weight onto his other self, hips thrusting jerkily while his cock pulsed and spilled wave after wave of release into Sheppard's gripping heat.
He was still shaking through his climax, cock twitching and spilling out deep inside his other self, when Sheppard went rigid, shuddering, and followed him right over the edge with a raw cry, ass clenching and spasming around John's cock so hard it bordered on painful. Panting and sweaty, wobbly on his feet, John held on for dear life and kept rocking his hips in shallow almost-thrusts against his double's ass while Sheppard worked himself through it and out the other side.
Silence fell in the small room, save for their raggedly panting breathing. John bit his lip, red in the face but unable to drag his gaze away from the sight of his own cock still buried in his other self's ass... But all too soon, he was softening too far to stay in there much longer and Sheppard was slowly straightening up again with a long, low groan.
John hissed in a breath, a jolt of sensation rippling through him as his spent cock finally slipped out of Sheppard's come-slick hole. Sheppard, fortunately, dug a roll of paper towels out from behind a box on the shelf John had just fucked him against. Once John had cleaned himself up as best he could, and Sheppard had wiped up the messes where they'd both come all over the goddamn floor at different times, John cleared his throat and did his best to banish some of the heat from his flushed cheeks.
"So... what did you haul me out here for, anyway?" he asked, clearing his throat while zipping up and half-heartedly straightening his clothes with a few tugs. He still felt weak in the knees; he couldn't remember the last time he'd come anywhere near that fucking hard.
Sheppard, having done the same, gestured towards the door. "It'll be easier if I let the expert explain it, I think. Now, don't freak out," he said as he led John through a narrow corridor, "'cause I know you don't know him as well as I do yet, but..."
John, frowning, followed his other self through another door and into what looked like the bridge of a small ship, though one he'd never been on before... And felt his jaw drop open as the tall figure standing at a wide central console looked up, cocked its head, and gave him a familiar, toothy smile.
"Ahh, welcome aboard, Shepparrrd," said Todd the Wraith. "It is a pleasure, as always."
John just stared flatly at the pair for a moment, Todd wearing an infuriatingly amused smirk and Sheppard slouching over next to him with a faintly chagrined shrug of apology for John; then he scrubbed a hand over his face with a long, weary sigh.
"You have got to be fucking kidding me."
