Every muscle locks. His breathing stops. His hands, resting on his knees, close into fists, and the claws dig into his own palms because the alternative is reaching for the boy and the reaching must not happen until the boy says so.
"Yes."
The word comes out before Lethe can ask. Before the question forms, before the hesitation arrives, before the boy can second-guess the wanting and pull his hand away. Zazyrus says yes the way he says vows: with his whole self, with the weight of everything behind it, and the yes is permission and invitation and plea.
Lethe's fingers continue.
Across his bicep. Over the curve of his shoulder. Down his chest, following the marking that curls over his pectoral, the one Lethe traced months ago in a cage with clinical hands that were not quite clinical. His finger follows the line lower, over the ridge of his stomach, and the muscle contracts beneath the touch and Zazyrus's breath comes out in a rush.
Lower. Over the hard plane of his abdomen. To the V of his hips, where the markings converge and disappear beneath his waistband, and Lethe's finger pauses there, at the edge, and his eyes lift to Zazyrus's face.
His cheeks are flushed. His eyes are clear. The firelight catches in them and they are bright and certain and wanting.
"You can touch me," Lethe says.
Zazyrus's restraint shatters.
He pulls Lethe into his lap. Both hands on his waist, lifting, settling, and Lethe comes willingly, eagerly, his legs partingaround Zazyrus's hips and his arms wrapping around his neck and his mouth finding Zazyrus's mouth and the kiss is immediate and deep and familiar. Not tentative. Not exploring. The kiss of two people who know the shape of each other's mouths and have missed the knowing since the last time.
Zazyrus kisses him the way he breathes. As though stopping would end him. His hands span Lethe's waist, his ribs, cradling with a tenderness that belies his size, and his mouth moves from lips to jaw to throat and the skin beneath his mouth is salt and warmth and the pulse point jumps and Lethe tips his head back and gives him more of it.
"Off," Lethe says against his hair. Already pulling at the waistband. Already efficient, already impatient, already Lethe. "Off, off, get these off."
They strip each other in the firelight. Lethe's shirt first, pulled overhead and dropped. Then Zazyrus's waistband, Lethe's hands quick on the ties. Then Lethe's trousers, Zazyrus's hands careful on the fabric, easing them down narrow hips. Familiar choreography. The practiced ease of two people who have done this enough to know the logistics and still want it badly enough that the logistics don't slow them down.
Lethe pushes Zazyrus flat.
Both hands on his chest, pressing him down onto the bedroll, and Zazyrus lets himself be pushed. He lies back and looks up at the boy kneeling over him, naked and hard and firelit, and the wanting in his chest is a physical ache, a pressure behind the ribs that is indistinguishable from pain.
Lethe settles between his legs. His hands run up Zazyrus's thighs, thumbs tracing the markings that scroll along the inner muscle, and his mouth follows his hands. He kisses the inside of Zazyrus's thigh, the skin that is softer there than anywhere else on his body, and the tenderness of the mouth on the tenderness of the skin is almost too much.
He does not tease. This is not teasing. This is Lethe being thorough, methodical, devastating in the way that only Lethe can be, the healer's precision applied to the project of taking Zazyrus apart.
He licks a slow stripe up the underside of Zazyrus's cock.
The sound Zazyrus makes is guttural and raw and ripped from the center of his chest. His claws dig into the earth on either side of the bedroll and the ground tears beneath them. Lethe's tongue is hot and wet and he knows exactly how to use it because he knows this body, has mapped this body, has spent enough time with his mouth on this body to understand the architecture of its undoing.
He takes the head into his mouth. His lips stretch around the width of it and the sight of it, the boy's mouth on him, the flushed cheeks and the closed eyes and the deliberate, focused concentration, collapses something in Zazyrus's brain. He groans. The sound is layered and long and barely contained.
Lethe takes him deeper. Slow and controlled, his hand wrapped around the base where his mouth can't reach, and the combination of the wet heat and the tight grip and the rhythm he sets, steady, unhurried, thorough, reduces Zazyrus to his component parts. His hips want to move. Every instinct wants to thrust into the slick heat of Lethe's mouth and he does not. He holds still. His thighs tremble with the effort of holding still and his breathing is ragged and his tail lashes the ground and the sounds coming from him are wrecked and continuous.
Lethe's free hand finds his thigh and squeezes. The squeeze means I know. The squeeze means I've got you. The squeeze is the wordless language they have built between them, the language of touch and pressure and the particular way Lethe's hand communicates when his mouth is occupied.
He works Zazyrus with his tongue. The underside, the ridge below the head, the slit at the tip where the taste is salt and bitterand Lethe swallows around him and Zazyrus's vision whites and his hand moves to Lethe's hair, resting, not pressing, the claws held carefully away from the scalp, and the restraint of that, the constant, vigilant restraint, is its own form of worship.
Lethe pulls off. His lips are slick and swollen and his voice is rough when he speaks.
"Not yet," Lethe says. His hand still wrapped around Zazyrus, still stroking, slow and loose and maddening. "I want you to come inside me."
The words hit Zazyrus like a punch. His cock pulses in Lethe's hand and his breath shatters and the wanting in his chest becomes something white and roaring that he has to clench his teeth against.
Lethe sits back on his heels. He reaches for the pack beside the bedroll and finds the vial of oil by touch, familiar, practiced, the small glass bottle from his healer's kit. He uncorks it and pours oil over his own fingers and meets Zazyrus's eyes as he reaches behind himself.
"Watch me," Lethe says. Quiet and steady and not a request.
Zazyrus watches.
Lethe's hand disappears behind him. His eyes flutter. His lips part. The first finger slides in and his breath catches and holds and his body adjusts with a small, tight roll of his hips. He knows this. He knows how to open himself, how to work the muscle loose, how to angle his wrist and curl his fingers and find the places that make his thighs shake. He knows because this is not the first time and because Lethe learns everything he touches and his own body is no exception.
