Chekov panted, pushing his palms harder into the wall in front of him, shoving himself backwards.

"Тяжелее, пожалуйста!" He moaned, feeling Jim's hand tighten around his hips. Jim released him, still pushing into Chekov, trusting him keep them steady. Jim leaned forward and placed his hands on the insides of Pavel's knees. He yanked upwards and fell backwards simultaneously, letting the Russian's full weight drop onto him. Pavel shouted hoarsely, "О, Бог, да!"

Jim groaned and pushed Pavel up a bit, Pavel switching his grip from the wall to the metal bed frame. Pavel was chanting ceaselessly, an endless litany of "Да, да, да, да, да," spilling from his lips. Jim altered his angle, leaning on one arm, his free hand wrapped around the back of Pavel's neck.

Pavel was panting, shoving himself harshly backwards, and crying out when Jim snapped his hips up to meet him. He felt Jim switch his angle, and his fingers tightened around the headboard, knuckles flushing white, cheeks pink. He moaned louder. "Трахнитесь!" he called, and he heard Jim growl behind him, and he pushed himself back harder, his arms quivering.

He felt Jim's hand move from his neck, stroking down and around his chest. Jim flicked his nipple once and his breath caught, the hand continuing its descent towards his hips. Pavel felt Jim's fingers encircle him, and he moaned, "Пожалуйста, капитан, я должен приехать," unsure whether the words came out in Russian or English.

Jim stroked him hard once, before leaning up to his ear and growling. "Да, Pavel, сделайте это."

Pavel loosed and almost-scream, slapping himself back once more, clenching tight around Jim, and came, feeling the other man stiffen in pleasure and groan loudly.

He pated hard, feeling Jim pull out of him, and an arm wrapping around him before he fell sideways, spooned comfortably in front of a warm body.

Jim's nose burrowed into the space beside his ear, and he heard a whispered "Я люблю Вас," followed by deep, even breathing against his neck.

He smiled, making a note to thank Lieutenant Uhura on his next shift, and promptly fell asleep.
