"You okay, cutie?" Marth asked, using his delicate fingers to brush Shulk's mussed hair out of his face as he weakly pushed himself up to a sitting position.
"Getting better," Shulk admitted, surprising himself with the lack of strength behind his voice. Ike had really fucked him senseless. He hadn't even possessed enough awareness at the time when Marth stepped into the room to react appropriately. In hindsight, he supposed he should have felt ashamed at being walked in on while in such a compromising state, but Marth was so welcoming toward his unexpected presence that his embarrassment was significantly eased.
"Well, keep getting better," Marth's thin, pretty lips smiled at him while his eyes half-lowered with mischief, "Because you're going another round in a minute." He stole a quick smooch before whirling away to finish undressing, leaving Shulk without the opportunity to respond.
Shulk observed Marth and Ike interacting in awe. At the beginning of his session with Ike, he'd daydreamed for a while about Marth, vaguely entertaining the notion of possible sexual escapades with him in the future... he never imagined that that future could happen now. Marth, looking even smaller with the hulking Ike beside him, cast Shulk a lusty look over his shoulder as he opened the front of his tunic and let it fall away from him. Round, pale shoulders and unmarked skin... Ike's big, calloused hands brushed over it, surprising Shulk to see such gentleness from him, especially remembering his own rough handling. He understood, now, what Ike had been talking about at the beginning of their session. Marth looked delicate, his skin like flawless porcelain – even if there was the lean muscle of a skilled swordsman underneath that skin.
Ike moved with such concern, his fear of breaking the smaller man evident to Shulk, even if that fear was unfounded. Shulk swallowed. So, perhaps Ike had looked forward to the rough session with Shulk as much as Shulk himself had – it was his chance, finally, to release himself of that concern, letting himself fully succumb to carnal pleasure. Shulk rubbed the back of his thigh, where he was sure a bruise would be forming, not regretting giving the man that chance at all.
Marth's long eyelashes closed – God, his eyelashes were so long – as he rose to the tips of his toes to sweetly go in for a kiss from Ike. Shulk's eyes traveled the curve of Marth's spine, enjoying the tapering in at his waist, giving the illusion of hips wider than they actually were. Ike's hands were at those hips now, too, reaching down into his loosely-slung pants to grip two soft handfuls of pale, pert buttocks. Marth unleashed a soft, sonorous moan, deepening their kiss, and Shulk watched tongues move between them. Involuntarily, his own tongue briefly flicked out, wetting his lips.
Marth and Ike's kiss broke apart, Ike looking a like he wanted to keep going, but Marth coyly pressed his index finger to Ike's lips as he backed away from him. As Marth slinked over to Shulk again, Shulk could only think about how incredibly otherworldly Marth was in his every sensual motion, his feminine beauty, and the commanding power he used those attributes for. Maybe it was his innate ability as a prince and a warlord, maybe it was just charisma (and damn good genes), maybe it was all of the above – but the fact that he had someone as huge and powerful as Ike melting under his gentle touch and hanging on every command like this was a testament to how much raw authority Marth possessed.
And he aimed to exercise it over Shulk now. His heart quickened in anticipation at the thought, watching Marth tantalizingly slip his leather pants down his thighs, then easing onto the bed to join him. He flourishingly trailed one finger along the side of Shulk's face, and Shulk melted against the touch, leaning in and closing his eyes to accept the sweet kiss Marth caught his lips into. Marth's fingers closed around the wrist he balanced on the bed with, lifting it up and pushing back, pressing Shulk onto his back, wrists captured beside his face. Marth smiled down at him, positioning himself to straddle Shulk's hips. He pressed their naked bodies together, kissing him again, both of them releasing soft noises at the stimulation in their groin regions.
Shulk still felt spent and tender, having reached orgasm not terribly long ago, but Marth seemed considerate of this, gentle as he rubbed over his cock with his own. They enjoyed each other like this for some time, languidly kissing, Shulk gradually being worked up again, hardening, growing more comfortable with the stimulation in his cock.
When Marth finally broke away, he looked over his shoulder at Ike, forming his pink lips into a perfect pout. "Ike..." he urged, and Shulk understood what was being requested as the prince perked his hips up, inviting his lover.
Ike was released from his daze. Truthfully, he was pleased just to watch the two of them enjoying one another, especially considering his view from this angle. But Marth's longing voice coupled with that irresistible expression, not to mention the lewd movement of his hips, snapped him to attention, and Shulk felt through the mattress that Ike now moved his weight over to join them.
Marth faced Shulk again, eyelashes low over his deep blue eyes. Shulk couldn't feel or see Ike entering Marth, but he could observe Marth's reactions, and that was nearly just as stimulating, as the sensation of Ike's huge cock pushing its way in was still fresh in Shulk's own memory. Marth's teeth clicked closed, and his grip on Shulk's wrists tightened as he braced himself against the entry.
Then Shulk realized that he wasn't sure if Marth was lubricated first. Ike's entry seemed awfully fast – even now, Marth was moaning, encouraging, "Mm, that's so good, Ike..." Unless there was a step Shulk hadn't observed, which he supposed was possible – then Marth was taking Ike's monster cock dry.
Shulk stared up at the reacting Marth, stricken with awe. He heard Ike grunt, and Marth was thrust forward, causing friction against Shulk's body, their cocks grinding together. Shulk absorbed what was happening on top of him – the gasping, grunting Marth, being fucked by Ike, his body thrusting up and down with Ike's strong, hard movements. Shulk had the clearest view of Marth's expressions, the prince whose erotic, measured beauty he'd just been admiring earlier, now heated with lust, grimacing and biting his lip and knotting his eyebrows and alternating through a myriad of other lewd reactions.
If he hadn't yet reached full hardness before, he certainly did now.
Freeing his wrists from Marth's grip, Shulk sent his hands to Marth's hips. He didn't expect to match the force of Ike's thrusts, but he could at least thrust up on his own as best he could, grinding his cock together with Marth's with even greater force. Marth unleashed beautiful sounds, accosted both back and front. Shulk wondered if he was going to come soon.
But Marth's stamina was greater than Shulk anticipated (and, in truth, Shulk had based his estimation on his own stamina, and he did not imagine that he would have lasted long if he were in Marth's current position). "Ike," Marth huffed between breaths, "Give... give Shulk a turn, too."
Shulk's eyes widened. He felt Ike's weight shift, and felt through Marth's bracing reactions that Ike pulled out from him. Ike's big hands went under his thighs, lifting him, working his knees underneath for leverage while Shulk's legs went into the air.
"Ah... w-" Shulk choked off his request to 'wait,' curious now as Marth shifted, too. Marth lifted from him, torsos separating as he sat up on his knees, smiling down at him. He took Shulk's cock in his hand, putting it in line with his newly-available entrance. Shulk felt his head pressing against Marth's hole at the same time he felt another, much larger head exerting great pressure against his own hole. "Oh..." Shulk groaned, understanding what the two were setting up. Marth leaned back against Ike, twisting at the waist to kiss his lover, cradling his face with his free hand, while the two of them pushed their ways in at the same time.
Shulk's spine sent his body in an arch, eyes rolling back, experiencing all over again Ike's huge tip penetrating his entrance, all while his own cock was pushed through Marth's hole at the same time. And Ike allowed no time for his body to grow used to his size again – he was thrusting, hard,almost at once. Marth simply rode along, laughing as he held his balance on his perch, which moved wildly below him under Ike's heavy thrusts. Shulk didn't even provide any thrusts of his own, doubting he had the strength to even if he made the attempt, those powerful thrusts Ike pumped into him providing enough to bounce Marth up and down his cock.
"Oh, oh God..." Shulk moaned, among many other wordless wails, surrendering completely to the other two. He had just enough awareness about him to confirm his earlier suspicion: yes, Marth was indeed taking it dry. The friction of his muscled hole traveling up and down Shulk's length made for an experience unlike even the few times he'd penetrated Robin, since they'd never skimped on lube in their encounters. And Ike slammedinto his ass, loud skin-slapping sounds resounding through the room with every impact, forming a double-rhythm with Marth's bouncing as well. Shulk wondered if Ike was driven to such extremes because he knew that the more power he fed into Shulk, the more Marth experienced it on his end, and Ike's desire to pleasure his lover trumped all else. Shulk's awareness was glazing over, but he briefly entertained the notion that at this point, Ike was essentially fucking Marth through Shulk.
"Oh, don't come yet, cutie," Marth pouted, hands going to Shulk's stomach in an attempt to brace himself and cease his bouncing. Shulk focused his vision enough to watch him, curious what the surprisingly perverted prince was plotting next. He pushed himself off Shulk's dick, making Shulk give a sad little "No..." at his stimulation having been cut off. Marth gazed at him lovingly and promised, "Don't worry, I'll take care of you."
He turned to Ike after that, and simply gave the command, "Up."
Ike's hands were hefting Shulk's legs up again, higher even than they already were, dragging his back forward across the quilted comforter. Shulk had no idea what position he was being dragged into, looking a little blank as he was manipulated around, until at last his weight rested on his shoulders and neck, the rest of his body upside-down, legs folded under Ike's hands. Ike was up on his knees – a man of more average height would have to stand to keep his dick inserted in an ass that pointed straight up like Shulk's did right now, but nothing about Ike's size was average.
He gave a couple experimental thrusts, testing his ability to thrust straight down, and Shulk feared his neck might break. "Here," Marth offered, seeing the boy wince, wedging a pillow under his neck and between his shoulders, a welcome comfort. Marth winked and leaned all the way down to plant a kiss on Shulk's cheek.
Now Ike truly resumed moving, and Shulk was repeatedly pushed into the mattress at the force of it. As his thrusts grew stronger, Ike really did rise from his knees to a standing position, bracing himself against Shulk's splayed legs. It allowed him to pull further out and thrust back down with more force than any of the other positions they'd tried. It knocked Shulk's breath out of him.
"Mm, look at that stomach," Marth marveled, running his fingers over Shulk's upside-down abdomen, the muscles folded up tight in his curved position. He kept his fingers moving, not resting until the wrapped around Shulk's bouncing cock. He barely had to move his hand, Ike's thrusting almost providing enough movement to Shulk's dick to deliver a handjob with a stationary hand. But Marth pumped with his hand nonetheless, if only to provide that much more stimulation for Shulk, whom he adored seeing absolutely losing his mind under his touch.
Shulk was melting wholly away, any and all coherent thought having flown from him. This position was so unusual, who would have imagined it could result in a fucking as hard as this? Shulk was mentally gone, nothing more than a vessel that simply took what Ike and Marth provided for him. His voice let out a high whine, and he could hardly tell what it was in response to, not even realizing that Marth had used his free hand to pinch and pull one of his nipples.
"Cu~ute..." Marth cooed, adoring every sound and expression Shulk produced. He felt Shulk's cock go rigid in his hand, veins bulging along its surface under his fingers. He smiled, immeasurably pleased, watching cum burst from the tip to spray Shulk's own face. Thick, wet globules stuck to his cheeks, across his nose, over his lips and dripping into his open mouth. Shulk's eyes were wide, blinking, not fully aware of what had just happened, his awareness still struggling to catch up.
Ike grunted, after allowing several moments to pass for Shulk to recover, finally extracting himself from his hole and guiding his legs and lower body back down to the bed. Shulk's back arched, not in ecstasy for once, just stretching his back and limbs after being folded up so forcefully through all of that. He groaned like one awakening from deep slumber, impulsively bringing a hand to his face to wipe his cum off, but flinched when his fingers touched it, unsure how to wipe all this off without just smearing it around, which would only be more embarrassing.
Marth gazed down at him with half-lidded eyes, licking his fingers to remove the traces that had stained him during the handjob. He was fixated on his widened hole, open and thickly filled with white, murky cum. There were at least two loads of Ike's in there, and Marth knew that was no insubstantial amount.
"What about you, Marth?" Ike asked him, one large finger brushing through the prince's soft, blue hair near his face.
"What, indeed," Marth mused, his eyes still on Shulk's hole as he crawled to approach it. "Bear with me a bit longer, Shulk," he ushered gently, resting his hands on the boy's knees, still weak and trembling post-orgasm.
Shulk groaned, perhaps in exhaustion at this point, but he did not resist Marth's entry. This was a new record of successional sex for him, and he wondered if Robin might grow jealous to learn about it and work to break it himself. Shulk had significantly more wits about him now compared to earlier, recovering from his orgasmic high, so he was conscious of how easily Marth slid in and out of him. A part of him worried that Ike had widened him to the point that he wasn't providing enough friction for Marth to be pleasurable, but Marth's real enjoyment seemed to be thrusting into Ike's milky, messy cum. It sloshed and splashed around inside of him, he could feel it, and occasionally Marth's angle of entry caused it to spurt out his hole in an arcing stream. The wet sounds and sensations were an entirely new experience for Shulk, enough to bring him no small amount of pleasure despite his weak, post-orgasm tiredness. And when he opened his mouth as his breathing grew heavier, his own cum loosed from his lips to drip into his mouth.
Marth cried out, and Shulk looked up to see that Ike was stimulating him further, arms reached around to pinch and tweak his nipples. He watched Marth's tiny pink nipples being pulled and pressed between Ike's big, massaging fingers, feeling his own going erect at the imagined stimulation. And then Marth was coming, his own liquid shooting into the pool of Ike's, mixing with it, before he quickly pulled out and released the rest of his load over Shulk's stomach and chest.
For some time, there was no movement in the room besides heaving shoulders, and no sound besides heavy breaths slowly evening out. Even while Marth caught his breath, his eyes traveled over the marvelous sight that was Shulk's debauched body. His hair fell messily about his face, sticking in cum, while more streams stained his torso, gathering in the creases between muscles. And a thick white stream continued to drip from his thoroughly abused hole, forming a puddle below him.
"That's... three sets of DNA on you now," Marth pointed out between breaths, stroking Shulk's leg affectionately, as it was all he could reach, too spent to move elsewhere. "Bring Robin with you next time, and we can make it four."
