He’d lost track of time, too busy drowning in the sensations coursing over his body. The sharp pull on his shoulder from how tightly his arms were tied behind his back, teeth and lips marking over a bare shoulder, torturous preludes to the occasional gentle rocking of Leo’s cock inside of him. He whined around the two fingers pressed into his mouth, and his twin responded with another nip to the bruised skin along his neck.


Donatello was face down in Leo’s bed, knees helplessly trying to keep him up but slipping with each shockwave of pleasure. His toes dug into the sheets as he rocked back into Leo, desperate to make him move again. He’d been brought to edge twice already, and each time Leo had pulled him away with wandering hands over his shoulders and thighs and a sweet mouth to kiss and lick across his shell.


He never pulled out, the warm pressure of his dick reminding Don of how close they both were, that Leo was doing this to himself too. He could feel him twitch and pulse inside of him. Donnie's own cock was pressed between his plastron and the pillow that had been propped underneath him. The fabric was soft and only served to tease him. With Leo leaning over him and his legs spread uselessly, he couldn't grind into the mattress to try and seek release. Not that his twin would let him do that anyway.


Leonardo pulled his fingers out of Don’s mouth, dragging the slick digits across his cheek and throat. His free hand slid over Donnie’s hip, stilling him and keeping him close. Lips pressed to his cheek as a questioning churr rumbled from Leo. Donnie whined again, responding with a broken churr of his own as he pressed back into Leo once again.


Suddenly Leo’s hands were on Donnie’s thighs as he pulled away. Bracing his knees farther apart, Leo pushed Don off balance even more with the spread of his legs. He rolled his hips once as the only warning to Don before he began thrusting into the tight heat around his cock. He picked up the rhythm faster than he had all night, and had Donnie been in a clearer state of mind, he’d recognize the signal that meant Leo was close and ready to bring them both to completion. As he was now though, all the genius could focus on was how Leo’s cock felt when it pushed back into him, pressing up against the bundle of nerves that made his toes curl against Leo’s shins and press his face against the sheets so he didn’t wake their family with his moans.


The pillow was pulled away and tossed to the floor before Leo’s hand wrapped around Donnie’s cock. He whimpered at the firm hold but let it give way to pleased gasps as Leo continued seeking out their pleasure. Leo leaned over Don again so he could churr against his neck and kiss the bites and bruises he'd left.


Leo's cock was hitting his prostate just right with every thrust, and Donatello could feel his orgasm building. His mind was fuzzy with pleasure, failing to warn him of his twin's smirk that he felt curl against his jaw. The hand around his cock moved to pump him, but as it drew back up to the base, Leo tightened his hold just as he struck Donnie's prostate again. The pressure around his dick stopped him from coming once again, but Leo didn't slow his thrusts despite Don's frustrated squirming.


The low rumble of Leo's churning was broken up by the sweet praises he was desperately whispering into Donnie's skin. Both hands found themselves on his hips as Leo's movements stuttered with his climax. He spilled into Donatello, a satisfied moan breaking past his lips. He kissed and licked the tears that had begun to fall down Donnie's cheeks after his last denial.


One of Donatello's legs finally gave out on him, forcing him to collapse completely to the bed under the force of Leo thrusting into him as he rode out his orgasm. He was too exhausted to move or struggle anymore. Reduced to a panting, over-stimulated mess now that his twin was almost done with him.


Lingering kisses found their way down Don's throat from his cheek, gently placed over the curve of his shoulder before trailing across his shell to where his hands were still tightly bound. Leonardo slipped his softening cock out of Don, resulting in a whimper that soon became a gasp as his arms were cut free next. The tingling sensation warred over the pain for a moment and made his arms feel as though there was a live wire running through each of them.


Donnie barely registered being rolled on to his shell until suddenly Leo was cupping his face with his hands for a wet, open-mouthed kiss. He moaned desperately into it, accepting Leo's tongue with a soft churr as he tried to push closer. Leo's hands left his face for his shoulders as he moved to kiss down his plastron. He carefully massaged the sore muscles down his arms, keeping pace with the attention his mouth was leaving over the sensitive lines and scutes of Donnie's plastron.


Donnie's cock twitched at the nearness of Leo's mouth. He was so close, it wouldn't take much for him to release, but Donnie refused to vocalize his begging and give Leonard more fuel. Luckily, Leo had his fill of Don's sweet cries for the evening. He dragged his tongue up the length of his weeping cock and pressed a kiss to the tip before swallowing Donnie down. Unable to hold back the impulse and secretly wanting Leo to deep throat him, Donnie bucked his hips up while his hand held Leo’s head. He pushed his dick farther down Leo's throat, relishing in the sharp intake of breath before Leo doubled down on his efforts and hummed once his lips reached the base of his cock.


Donatello's orgasm seized him with a passion only Leo could give him. His vision faded and he floated in a sea of cotton nothingness until he heard Leo calling him.


"Donnie…" Leo's voice sang to him. He was running his hands over Don, anywhere he could touch. Don's hand was resting on his shoulder where it fell. He cradled Leo's face with it, running his thumb over the red marking by his eye. Leo nuzzled into the touch, turning to kiss his palm. He kept his eyes on Donnie the entire time. A wicked smirk made its way back to Leo's face, the same one he wore before they got lost in each other on Leo's bed.


"Now," He whispered, leaning in closer to Donnie. "What was this favor you wanted to ask me?"
