She really ought to be more careful.
River knows this, knows it as MacCready claims her hips in his hands and closes his teeth around the base of her throat, knows how easily she loses track of time and space and responsibilities when she lets him get his hands on her. A few hasty kisses between meetings have already evolved into his tongue at the curve of her lip and the hard shape of his cock pressed between them. MacCready seems to want her with a hunger verging on starvation, and knowing the way her body craves him back…
She really ought to be more careful.
Instead, she drags him by the hand into the tool shed around the side of Preston's house, closing the door swiftly behind them. She catches his smile just before he kisses her, her face in his hands, pinning her back against a set of metal shelves. He sucks her lip between his teeth, licking into her mouth, as if they haven't kissed in years and he's forgotten what it's like - that gentle, endless way he always savors her.
River moans when he nips her throat, just beneath her jawline. "I-I don't have much time -"
His mouth softens against her skin, lazy, lingering kisses that draw like tides at her heart. "I'll take every second I can get." He lifts his head to nibble at the shell of her ear, and she shudders in his arms. "Quiet, yeah?"
"Mmhm!" She nods, already inching his shirt up his chest, and he laughs under his breath as he pulls it over his head. He makes quick work of her clothes; he's ripped her out of them more times than she could ever dream to count, and his skilled hands and muscle memory soon have her half-naked in the tool shed. She pulls his belt loose, slipping his pants down his thighs, and then his cock is thick and silky in her hands, and the sound he makes - so rough and pure, the way hunger burns, like the rush of her heartbeat, there's nothing sweeter than when MacCready wants her like this.
"Wish I could taste you first," he groans, just breath and syllables at her ear as he crowds her against the rusted shelves. She grips at cold metal above her for some center of balance while her head spins, panting, breathless, squirming at his fingers searching between her thighs. "Later," he promises in a gruff voice, teasing calloused fingertips along her sex. She can hear the wet slick of his fingers as he finds the dip of her cunt and pushes in, biting a groan into her shoulder at the warm, velvet feel of her. His fingers fill her slowly, fucking deeper, languid, tracing determined shapes until she's trembling and biting into her fist to keep herself quiet.
"Here," he murmurs, wrapping his hand around her wrist and tilting his head back, offering the column of his throat. She whines and sinks her teeth into his shoulder, anchoring them together as he lifts her legs around his waist. She feels the thick head of his cock nudging at her thighs, finding, parting slick folds and driving home in one fluid push. The breath catches in her throat, and her mouth sucks hard at his skin, biting back each wild cry that threatens to break free. MacCready ducks his head and mouths a breathy fuck as he rocks his hips, sinking deeper, and for a few heartbeats, her world narrows down to his hands and his mouth and how fucking thick he feels inside of her.
Tools and bottles rattle on the shelves as he thrusts into her, fingernails digging crescents into her hips. With the white-knuckle hold she has around the shelf above her, River swings into each pump of his hips, and when he hilts hard and fills her, she can't hold back a high-pitched squeal. His mouth finds her neck and bites down, a punishment of teeth and suction that makes her shiver and whimper his name.
He shushes her between rough kisses down her throat, even as his voice threads raw and heavy with need. "Gotta do better than that, baby," he whispers, slowing his hips to sink in inch by inch, and River's nails cling urgently into his shoulders as he fucks her. He grunts when the blunt of her teeth catch his neck, lean muscle tensing beneath her tongue. "Fffffuu -" His voice stutters out into a groan. "God, you feel so good."
MacCready latches his mouth at the base of her neck, and the sharp pleasure-sting sets her reeling toward the edge. She falls into the sound of his breath, wrecked and ragged at her ear, his steady grip around her thighs, the webbing swell of pleasure when he fills her with the thick weight of his cock.
"RJ, I'm -!" She feels her mouth form the words but can't quite find the breath to voice them, just locks a scream behind her teeth before he rolls a thumb over her clit and makes her come. She has to clamp her teeth into his skin to keep herself silent, shuddering between his body and the hard bars of metal behind her, teetering on the cusp of a frenzied scream and barely hanging on.
Something bulky and metal falls from one of the shelves, shaken loose by their urgency and promptly ignored as MacCready bites down into pale, smooth skin and spills inside of her, choking out a broken moan at the base of her throat.
In the breathless wake of coming down, he drags sated kisses over the marks he's left behind, her name barely there on his voice. Gingerly, he eases her back onto her feet, murmuring something about being too loud, and with the smug, satisfied gleam in his eyes, she really can't bring herself to regret it.
But next time, she really ought to be more careful.
