Chapter 8: Sunrise Dosing
The first light of New York dawn painted itself across the ceiling of Tony’s penthouse bedroom, a cold, pale blue that did nothing to touch the fever under his skin. He’d woken like he always did now: drenched in a cold sweat, his heart thumping a frantic rhythm against his ribs, every nerve ending shrieking with a hollow, electric need. The bed, a vast expanse of custom-engineered memory foam and Egyptian cotton, felt like a prison.
He lay on his back, sheets tangled around his ankles. Across the room, Damon was a shadow against the floor-to-ceiling windows, looking out at the waking city. He was already dressed in simple black trousers and a worn gray t-shirt, a silhouette of contained violence.
“It’s starting,” Tony said, his voice raspy. He hated the need in it.
Damon didn’t turn. “I know.”
“You can just… feel it?”
“I can smell it.” Damon finally turned. His blue eyes were cold in the dim light. “Your body chemistry shifts. The acidity of your sweat changes. It gets sharp, anxious. Like an animal in a cage.”
Tony pushed himself up on his elbows. “Charming.”
“It’s biology. Your body’s screaming for the antigen mine produces. The one you’re not making. So it starts to eat itself from the inside out.” Damon walked toward the bed, his movements deliberate, silent. “Two doses a day keeps the feral away. That’s the schedule now.”
He stopped at the edge of the mattress. Tony’s mouth went dry. The clinical analysis dissolved under the weight of Damon’s gaze, replaced by the same raw, shameful hunger from the training room. It was worse in the quiet privacy of his own bedroom. There were no missions here, no excuses.
“The schedule,” Tony echoed, a weak attempt at defiance.
Damon placed one knee on the bed, then the other, crawling over Tony with a predator’s patience. He didn’t touch him, just hovered, his weight shifting the mattress, surrounding Tony with his heat and his scent. “You think you can negotiate? Look at you. You’re shaking.”
Tony was. A fine tremor ran through his hands, up his arms. He let his head fall back against the pillows, exposing his throat in a gesture of surrender he didn’t have the strength to fight. Damon’s eyes tracked the movement.
Slowly, Damon hooked his fingers in the waistband of Tony’s black silk sleep pants and drew them down. Tony didn’t help, didn’t resist. The cool morning air kissed his skin, but it was nothing compared to the heat of Damon’s stare. He was already fully hard, his cock lying heavy against his stomach, a traitorous beacon of his need. A bead of precum welled at the tip.
Damon’s gaze fixed on it. He didn’t speak. He lowered his head, his dark hair falling forward, and inhaled deeply at the junction of Tony’s thigh and groin. A low, almost soundless growl vibrated in his chest.
Then he bit him.
Not a playful nip. A sharp, sudden clamp of teeth on the sensitive flesh of Tony’s inner thigh. Tony jolted, a cry caught in his throat. It was pain, bright and shocking, followed instantly by a wash of dizzying pleasure. Damon held the bite for a long, agonizing moment before releasing the flesh, leaving behind a dark, perfect imprint of his teeth.
His tongue followed, a hot, wet stripe licking up the trail of precum that had leaked down Tony’s shaft. He took his time, his tongue flat and deliberate, cleaning him with a blasphemous reverence. Tony’s hips bucked involuntarily, a broken sound escaping his lips.
“Stay still,” Damon murmured against his skin, his breath hot. “This is my dose, too. I’m going to take it slow.”
He didn’t use his hands. He used his mouth, his tongue, his teeth. He licked and sucked at the head of Tony’s cock, swallowing the bitter salt of him, teasing the slit until Tony was panting, his fingers twisting in the sheets. He took him deep, then pulled off to trace the prominent veins with the tip of his tongue. He nuzzled his balls, inhaling, before sucking one gently into the heat of his mouth.
Tony was unraveling. The scientific part of his brain was offline, flooded with endorphins and the pheromonal cocktail only Damon could provide. “Please,” he heard himself whisper, the word raw and shredded.
“Please what?” Damon asked, pulling back. His lips were swollen, glistening.
“I need… I need you…”
“You need me to fuck you. I know.” Damon shifted, finally stripping his own clothes off with efficient, unceremonious movements. His erection sprang free, thick and flushed. He leaned over Tony, bracing himself on his forearms, their cocks sliding together in the mess of saliva and precum. The friction was exquisite torture.
He didn’t enter him. Not yet. Instead, he reached for the bottle of water on the nightstand, took a mouthful, and then, maintaining eye contact, let a stream of it cascade from his lips onto Tony’s exposed hole.
Tony shuddered at the sudden coolness. Damon spat the rest of the water into his palm and used it to slick himself, his hand moving in slow, tight strokes. “You’re going to take every inch,” he said, his voice a dark promise. “And you’re going to come untouched, just from my cock splitting you open. That’s how we know it’s working.”
Positioning himself, he pressed the broad head against Tony’s entrance. The pressure was immense, unyielding. Tony forced himself to relax, to breathe out, and with a slow, relentless push, Damon began to sheathe himself.
It was a brutal, breathtaking fullness. Tony gasped, his back arching off the bed. Damon didn’t stop. He pushed in steadily, his jaw clenched, until his hips were flush against Tony’s ass. They stayed like that, joined to the hilt, unmoving, while Tony’s body struggled to accommodate the invasion.
“Feel that,” Damon whispered, his own breath hitching. “That’s the only thing that fits inside you now. The only thing that quiets the noise.”
He began to move. A slow, deep withdrawal, then a punishing thrust back in. He set a rhythm that was less about pleasure and more about possession, about marking and claiming. Each stroke dragged against Tony’s prostate, sending lightning bolts of sensation up his spine. His own cock, trapped between their sweat-slicked stomachs, leaked continuously, a steady dribble of precum.
The sound was obscene: the wet slap of skin, their ragged breathing, the soft, choked sounds Tony couldn’t keep inside. Damon shifted his angle, driving harder, deeper, and Tony saw white at the edges of his vision.
“That’s it,” Damon grunted, his pace becoming erratic, his control fraying. “Your body knows. It fucking welcomes it. Clenching around me like a greedy little fist.”
His words, filthy and specific, tipped Tony over the edge. The orgasm didn’t crest; it detonated. It tore through him with a violence that stole his breath, a silent, seizing convulsion that milked Damon’s cock deep inside him. He came in thick, helpless stripes across his own stomach and chest, his vision tunneling.
The clenching spasms triggered Damon’s own release. With a guttural shout, he buried himself one last time and came, his hips stuttering as he pumped his load into Tony’s depths, hot and seemingly endless.
Collapse was inevitable. Damon’s weight came down on him, heavy and spent. For long minutes, the only sounds were the hum of the penthouse systems and their slowing breaths. The frantic need had been replaced by a profound, chemical stillness.
Damon was the first to move. He pulled out with a soft, wet sound that made Tony flinch. He stood, looking down at the wreckage of the man on the bed: spent, covered in his own release, filled with Damon’s.
Tony couldn’t meet his eyes. He stared at the dawn-light now gilding Damon’s shoulder.
“Clean up,” Damon said, his tone flat, devoid of the heat from moments before. “Your team meeting is in an hour. Rogers wants a mission debrief.”
He walked toward the ensuite bathroom. Tony finally turned his head, watching him go. His gaze drifted past Damon’s retreating form, across the room to the sleek control panel by the door. A small, non-descript black square was mounted just beside it, nearly indistinguishable from the wall panels.
A tiny, fresh red light winked on its surface. Steady. Unblinking.
It hadn’t been there yesterday.
A coldness seeped into Tony’s gut, colder than any withdrawal. The chemical calm shattered, replaced by a new, razor-sharp fear. He was being watched. And Damon, pulling a clean shirt from the closet, hadn’t seen it.
