"Stay close to me," Don whispered, into the quiet dark of his bedroom, into the space he knew where Leo was sleeping beside him.
Leo was close, but he inched closer, until their knuckles brushed beneath the covers and he could gently take Don's hand in his own.
Leo traced the pads of his fingers over the back of Don's palm. They traced over the little nick in the join between his thumb and forefinger, exactly where Leo remembered that time Don had been a little careless with a refurbished buzzsaw they'd found.
Their beaks brushed together. Leo could feel Don's soft breath against his mouth.
The urge to lean into it was overwhelming, so he did.
Their lips opened and closed tentatively, at first, as if they'd never tasted anything before, as if the world had been made of stale bread until this moment, and it was strange and terrifying and impossibly sweet. Don trembled into Leo's mouth and Leo took Don's lower lip between his teeth.
Their knees brushed. Leo wrapped his ankle around Don's calf, hooking them together securely. His free hand smoothed up Don's corded bicep to latch onto his shoulder.
Leo could feel a heat rising, first to his stomach and then to his cheeks, fusing his mouth to Don's as their jaws opened and their tongues spilled out to tangle together.
Leo rolled his hips forward and Don fell backward, pulling Leo on top of him and gasping when Leo's knee landed between his spread legs. The heat was everywhere now, billowing over their skin like steam, the curling tendrils rising into their heads to make them fuzzy and blissfully lost in the dark.
Leo's hands wandered down Don's sides and wrapped around the backs of his thighs, hoisting his hips open wider to make parts of them that never had touched until now grind together hungrily.
His palm landed with a thud against the wall as it braced them against the forced of their moving bodies. Their gyrating hips were causing their plastrons to scrape deliciously, and it produced an unusual and intoxicating sound that drifted all around them.
Leo groaned, burying his face in Don's neck, nibbling every bit of skin his lips met.
Don wrapped his arm around Leo's shell, bringing his legs up to wrap around his waist, indulging in the feel of their bulges pulsing like heartbeats between them, like two mouths chastely kissing. His head fell back on the pillow as Leo's lips traveled up his neck, over his jaw, and retook his lips with a fury.
"Am I close enough?" Leo growled into Don's open mouth.
Don bit Leo's lip and then lapped his tongue over the spot. Unable to keep his expression insulated from the joy coursing through him, he smiled wickedly into his brother's mouth.
