Chapter Text
Curiosity lingered on the tip of his tongue as Eighteen undressed him, disrobing his sleep attire easily enough. He held his breath. Excitement fastened into his veins.
Seventeen would be lying if he said this hadn’t been plaguing him. Each time Eighteen looked at him, gorgeous grey eyes on him, a burning heat set fire in his groin. His blood pumped faster, reaching to his cheeks to form a blush and to his cock, hardening itself, aching to be touch by firm hands.
“Just the tip,” Eighteen had said. In the cold room full of rifles and ammunition, Seventeen wanted more. Something to warm him up further. Hiding away someplace safe was necessary. No one came down here at night.
He laid on the weapon table, legs raised high as Eighteen held onto Seventeen’s thighs for a moment, the warmth from his palms prickled him with need as he laid on his back. His cock jerked. Soon Eighteen lined up his cock with the hole, ass spread and gripped, rubbing precum onto the clean slit. He shuddered as Eighteen pushed in, the flesh of the tip teasing him like withholding a toy from a dog.
He bit down his tongue from uttering a moan. They couldn’t be heard no matter what. If they were caught...
Eighteen edged him, until his cock reached further inside. It nearly made him scream out in pain despite the slick and sweat as lube. It simply wasn’t enough for a smooth passage.
“Are you trying to rip me open?”
“You like this, c’mon. I see how horny you are. We are, in fact.”
That was true, and he did want the pain if it meant Eighteen was fully in. But experiencing the pain in practice was different than thinking about it in theory.
As if he knew what Seventeen thought, Eighteen replaced his tip with a warm, wet finger, curling the meat inside. He gritted his teeth to avoid a whimper. Hands gripping the dusty cloth on the table. Mastery of self-control was absolutely needed here.
“Make some cute sounds for me. You can’t hide,” he giggled.
“And why,” Seventeen whined. Eighteen had sent another finger within, twinning his digits deeper in the sensitive area. “Scum.”
Eighteen laughed at the remark and took his time stretching the muscles as they came undone. Relaxing at each engrossing touch; it was addictive the way it made his mind hazy. He soon was ready.
The pressure was overwhelming: his entrance squeezed as Eighteen fused his cock ever slowly. He bit his tongue again to shut down the noise within himself, but his double leaned onto his belly in faux disapproval. The heat when merged together felt blistering, as if he’d walked right into the sun. “No no no, naughty boy,” Eighteen whispered close to Seventeen’s blush ear, a finger intruding into his lips, forcing them to part open. “I want to hear you.”
Eighteen thrusted. Seventeen whimpered, his mind blurring with lust as his clone picked up his pace. The fullness of the cock within made him needy, whining aloud nonsense as he’d tried to form a coherent word.
His double came, warm and buzzing. The cock pulsed inside, like a quicken heartbeat, unpacking its semen to its fleshy destination. At the same time, ironically, he’d came. White slick stained his and Eighteen’s stomach. It painted a beautiful picture which they’d need to clean soon.
“You were so good.” Eighteen bit his ear playfully. “When are we doing this again?”
... again? They couldn’t, their existence while together, even platonically, couldn’t happen. It wasn’t a chance they could take again.
“Tomorrow.” His voice was quiet, his body’s needs betraying safety and logic for another round with his clone. “Or sooner.”
