Work Text:
John had meant to shower. He had been in the field for days without access to running water but the moment he stepped through the door he was practically falling over. Bob helped him strip his uniform and allowed him to collapse into bed in his boxers and undershirt. He barely noticed Bob snuggling in beside him.
He didn’t know how much later it was when he dragged his eyelids back open. Blinking away the sandy feeling as hisneyes focused in the darkness of his room. The sun must have set hours ago— the moon no longer shining through his thin curtains.
The room was cold and he realized he fell asleep on top of the blankets. He registered Bob's solid warmth beside him, rocking a bit in his sleep.
At least John thought he was asleep. When John tried to lower his arm, shoulder aching, Bob's fingers wrapped tight around his wrist. His breath tickled the hair where his face was nestled under John's arm.
"Bobby?" he whispered, not wanting to wake him if he was asleep. Bob got so few actually restful nights.
"Sorry," Bob muttered into the hair. "Didn't mean to wake you."
"What are you...?" John asked, mind still bleary.
"You smell so good," he moaned, nuzzling deeper.
"Bobby, I'm gross—," John protested, writhing a bit under Bob’s weight.
Bob only nodded, moaning again. His hips shifted against John's thigh and John suddenly understood.
"Oh, fuck, baby," John groaned, his own crotch aching with a warmth he'd yet to fully register prior. "Baby," he said again, his hand moving to grip Bob's waist. Somehow it made his neck ache more to lower one arm, but he didn't really mind. He just wanted to feel more of Bob's need.
"I'm sorry," Bob whined, and John felt a weird sensation that took a few moments to fully settle in his mind: Bob licking over his armpit. There was a soft moan from Bob and John felt his cock throb as Bob rocked his hips forward again, his knee pressing between John's legs. "I'm sorry, I should have asked first..."
"It's fine," John said, trying to focus on how weird it felt for Bob to lick his armpit, and not the fact that he could feel how wet Bob was as he humped his thigh. "I've told you a million times, Bobby. Just do whatever you want."
Bob whined as his fingers bit at John's wrist. The sound rolled into a moan as John leaned up just enough to catch a quick golden ring in his eyes. "You smell so fucking good, Daddy."
John groaned deep from his chest, swallowing hard as the length of Bob's cock slid along his flesh. "Don't take your face out of my armpit again," he ordered.
Bob moaned, nestling his face hard under John's arm. His tongue ran broad strokes through the hair as he breathed deep. John could feel his hips rocking faster, his cock sliding easily over John's slick skin. He was panting and whining into John's pit.
"Fuck, baby," he groaned, trying to focus on the tickling sensation, the wetness coating the hair and not Bob’s needy noises or the glide of his cock over his thigh. "You like how Daddy smells?" He grunted, feeling his own cock twitch.
"Mmmmff," Bob nodded, tongue still out.
The hand around John's wrist squeezed harder as Bob's movements grew unsteady. His breathing was ragged, panting and desperate. John pulled him closer, hand guiding his hips as they grew more frantic.
"I've got you," John encouraged. "That's right, get in there," he moaned as Bob pressed his face harder into John's scent.
"Smells just like you," Bob mumbled, his voice cracking and cutting off with a moan. "Daddy..." He moaned and John felt a pulse of warmth over his thigh.
"Fuck."
"I like it when you're sleeping and you don't even know how dirty I'm being," Bob said between needy licks, moaning as he practically folded himself in half to get his mouth on John while humping his leg.
"Mmm... But I like my dirty boy," John said, digging his nails into Bob's ass, tugging him closer until he felt Bob's cock catch at the edge of his boxers. "Shit," he hissed, tugging the pant leg from up by his hip. Just that little bit of sensitive skin exposed to Bob's drooling cock was enough to make John's own heart kick in his chest. A tight squeeze of desire as he felt it run through him. "Fuck," he breathed as his toes curled and his shoulders tensed.
"—get embarrassed," Bob admitted, still nuzzling into his underarm. John wasn't sure what he'd missed over the rumbling in his head.
"What else do you do that I don't see?" he pressed, mind running wild with the thought as Bob humped his thigh. He could already feel his cock twitching desperately, and if the cold spot in his boxers was anything to judge by he was leaking steadily.
"Mmm," Bob hummed, the sensation tickling a little. "Steal your clothes," he muttered. "Boxers are my favorite," he admitted, breathily.
That made something twist desperately in John's stomach. "You miss me so much you steal my undies?" he asked and Bob nodded. John felt light headed.
"Smells like you," he moaned.
"So do my shirts," John said, though he already knew Bob liked to wear those.
"Mmm... Your boxers smell so much more," Bob said, pressing his mouth down on the muscle beneath John's pec, sucking hard and moaning as his hips made little jerky movements.
"You steal 'em just to sniff?" John's body felt so tight—wound like a fucking spring, so close to snapping.
"Mm-mm." Bob shook his head before spitting John's muscle out and kissing back up to the curve of his pit. "I sniff them and touch myself."
John moaned at that, his back arching and his arm pushing up against Bob's hand involuntarily. "Fuck." His face squeezed tight as he fought the orgasm knocking at his belly. "Wh—What else, baby?"
"I like to touch you while you sleep," Bob said quietly, dragging his nose along John's pit. "I like making you hard and teasing you. You make more noises, but they're so quiet."
"You play with me while I'm sleeping?" John's face was so hot he thought he was blushing.
"Yeah." Bob whined, writhing a bit on John's thigh as his back muscles spasmed. "Yeah, Daddy. I love playing with you."
"Fuck, baby, I love playing with you, too." John's breath caught as Bob shifted, one hand slowly snaking down and cupping his cock through his boxers. "Wait, baby, I'll—" He cut himself off with a loud and violent moan, unable to hold on a single second longer with Bob's hand on him. It didn't matter that there was a thin layer of fabric in the way. The pressure and the heat and the fact that Bob liked to touch him was everything he needed to send him tumbling over the edge.
"Oh, fuck, Daddy." Bob moaned, grinding down hard on John's thigh.
John was panting, body clenching tight as he felt himself coat the inside of his boxers. "Baby," he moaned, hips twitching under Bob's weight.
He was still riding John's thigh, lips wandering under his arm— through the hair along the tendon and along his ribs.
"You sound so relaxed when you're sleeping," Bob continued. "You snuggle me and play so gentle." He moaned hips moving faster as he told him.
"You want me to play more gentle?" John asked, fingers reflexively loosening on Bob's ass.
Bob quickly shook his head. "Nuh-uh," he protested and John tightened his hand again. "Want— fuck," he groaned, hips stuttering. "Daddy," he whined.
"I've got you, baby," John comforted.
"Play rough with me, Daddy," Bob whined again, nipping at his skin.
"You want rough?" John asked and Bob nodded. "How rough?"
"Mmm..." Bob moaned helplessly so John made the decision for him and ground his thigh up mercilessly. "AH!" Bob yelped, though he pressed his face in harder under John's arm.
John's fingers dug into Bob's ass, guiding his hips down hard as he rocked his leg up in time with his thrusts. "You gonna cum for Daddy?" he growled and Bob nodded hard, moaning into his pit. "Fuck, baby," he groaned, hand moving from Bob's ass to curl in his hair, pressing his face hard into him. "That smell good?" he asked, Bob whimpering in response. "Dirty boy getting off on Daddy's scent," he teased, feeling the way Bob was starting to shake. He pressed his thigh up hard enough he feared it would hurt.
Bob cried out, loud and gasping as he continued to ride his thigh. "Fuck, Daddy, please, more," he whined and John thrust his leg up again to comply, earning a drawn-out moan.
"You gonna cum sniffing me?" John teased, pressing his thigh up even harder, grinding it against Bob's crotch.
Bob made a punched out sound as he met John's thigh, and he knew the pressure must hurt. "C—Can I? Please, Daddy... mmm..."
John gripped tighter at Bob's flesh and barely made out a, "Go on, baby. Cum because you love my scent so much."
Bob's body shuttered, hips twitching as he came, his shout muffled by John's hair. John held him tight, cum painting his leg.
Bob collapsed on top of him panting as he tried to catch his breath. John stroked his hands over Bob's back, soothing him as he came down from his peak. John was almost asleep again when Bob finally spoke.
"Sorry," he mumbled, trying to roll off of John but John stopped him, arms pinning him to his chest.
"What for?" John asked.
"Shouldn't've woke you." His voice was muffled against his pec.
"Did you have fun?" he asked. Bob nodded. "Then it's fine. I don’t mind waking up to take care of you," he assured, pressing a kiss to his forehead.
John's arm, shoulder, and body kind of hurt from keeping his arm up, but feeling Bob breathe on top of him was so worth it.
"Really?" Bob asked, hiding his face in John's chest.
"Yeah," John yawned. "'Course."
Bob kissed him and he could taste his own sweat mixed with his saliva. Eventually he let Bob roll off of him, his shoulder aching as he lowered it. He waited for Bob's breathing to even, the man snuggled tight to his side, drifting back to sleep himself.
