Neanderthals Made Them Do It.

There were leaves above them. Leaves were good. Leaves were normal, and something to focus on instead of the crowd of Cro-magnons that surrounded them and the fact that they all had very large sticks and the fact that they were watching -

"Come on, Cutter." Ryan's voice caught his attention, brought him back to warm eyes and soft kisses and the scent of gun oil, Ryan's fingertips pressed back between his thighs, rubbing slick against his asshole. "Try to relax for me, all right? Don't think about them. Just focus on me."

Nick swallowed, letting out a slow breath and forcing his body to adjust as Ryan pressed a finger into him, stroking slowly. It ached, and an erection was pretty much out of the question at this point. But it was either this or one of the Neanderthals, so the choice was a no brainer. Why they'd decided that -he- was a good candidate for a mate was beyond him.

"Just do it," he muttered. "Get this over with so they'll leave us be and we can find our way home."

Ryan shook his head, easing another finger with the first. "Not going to hurt you."

"Ryan, please - " Nick drew a sharp gasp, words broken as Ryan's fingers twisted just so, brushing against something sensitive deep inside him, sending a flood of sensation through him. The scientist in him thought 'prostate'. The rest of him thought, "Oh!"

Ryan gave a slightly relieved sigh and continued working his fingers in him, gently teasing against that spot. "See? It's going to be just fine, trust me. You'll be fine."

Perhaps something could talk his erection into coming back after all. Cutter let out a shaky breath and nodded, closing his eyes and trying to ignore the slightly more boisterous sounds coming from the onlookers. He needed to focus on Ryan's fingers, on the press of his lips and his soft, soothing encouragements. On the scent of aftershave and sweat and gun oil. He whimpered as Ryan's fingers pulled from him, looking up at the soldier that knelt between his legs.

Ryan shifted to press their cocks together, pouring more of the gun oil over them before curling his fingers around them to stroke them both. Nick had reached to help before he'd thought about it, fingers slicking though the metallic scented oil, over Ryan's skin, over his fingers. Ryan's dick was hard and hot against his own as Nick rocked up against him almost desperately, searching for more sensation. "Ryan, I've never...."

"I know. It's all right." His gaze flicked to the audience for just a moment, distracted, but even Nick could tell they were getting impatient. Ryan pressed a warm kiss to his mouth, slipping his arms behind Nick's knees and pulling his legs up. His voice was firm and low as he rocked slowly against Nick's ass, erection sliding against his entrance, letting him adjust a little to the feeling of stimulation, the idea of penetration. "Breathe out, push back against me. Just look at me, just focus on me."

He continued speaking softly as he moved, pressing against Nick, slowly breaching his body, breath hitching as he did. Nick latched onto his mouth like a man drowning, stealing trembling kisses, gasping against his lips between each one. The burn of penetration was more intense than he'd ever expected, an uncomfortable sensation that crawled spidery up his spine, but at the same time the drag of Ryan's cock against sensitive nerves and the feeling of being filled was surprisingly nice, and quickly overcoming the discomfort as Ryan rocked deeper into him.

There were noises coming from the onlookers - unmistakably approving, thank god - but Nick kept his gaze on Ryan, wrapping his arms up around his shoulders. "Keep going."

Ryan nodded, dotting his mouth with kisses as he started to move in him, a slow rock that sent shivers of sensation through him. "That's it... doing so well, Cutter... god, you feel amazing."

Nick managed a gasped affirmative, encouraging him with little bucks of his hips, fingers clenching at strong shoulders, at muscles that bunched under his fingers. "More," he gasped, groaning as Ryan complied, thrusting a little harder into his willing body. Then he shifted, pulling Nick's hips a little higher, and somehow their bodies came together in a way that left Nick seeing stars. The scientist again thought 'prostate' but the rest of him was barely coherent enough to think, 'So THIS is why men have anal sex.' "More," he gasped again, even though his body was starting to tremble from the position, his knees pushed up almost to his chest. He could feel every inch of Ryan's cock inside him, big and hot and hard, unerringly hitting against that spot with each thrust. It was too good to stop. "Oh god, Ryan, harder!"

"Nick!" The soldier's head dropped to Nick's neck, his breath in hot pants on his skin. Somehow hearing his name on Ryan's lips, gasped almost helplessly, made this all even more erotic. Nick managed to work a hand between them, curling it around his cock and working with Ryan's thrusts to stroke himself. "Dammit, that's hot," Ryan gasped, hips bucking harder into him, hands curling around Nick's shoulders, bracing him against his thrusts as their bodies fell into a hard rhythm.

The build of pleasure was hot and fast and almost uncontrollable, and before Nick knew it he was squeezing the base of his cock, trying to hold back the tide of sensation, the hot shocks of pleasure Ryan drove through him with each thrust. He was almost trembling with the need to come, breath in harsh, throaty cries. "Let go," Ryan breathed, voice low and rough from sex but somehow still authoritative. It was the last straw for him, and Nick's breath caught in his throat as he came, pleasure and sensation rushing through him, almost painfully intense as he splattered his seed in his hand and onto their stomachs. He could feel his body clench and shudder around Ryan, and the other man gave an almost helpless cry, bucking deep into him and flooding him with warmth.

When the world came back into focus, Nick realized with a surge of relief that most of the Neanderthals seemed to have wandered off, apparently satisfied that Nick had been well and truly claimed. He whimpered as Ryan pulled away carefully, still trying to catch his breath. This he was definitely going to feel tomorrow. Ryan pressed the canteen from their pack into his hand, and Nick gave him a smile, gulping hungrily of the cool water. "Thanks."

As they made their way back to the anomaly, Ryan was quiet in an uncharacteristically somber way. Nick glanced back at him, shielding his eyes against the sun. "So. Think we could do that again sometime without the audience?"

Ryan's face broke into a grin. "As long as I can buy you dinner first."
