Natsu had just finished tossing everything into the dryer when Gray came into the laundry room, dressed only in a pair of Rogue's sweatpants.
"Yes, I separated the darks and colors," Natsu grumbled, rolling his eyes and reaching out to grab Gray's hips. "And I hung up your dress shirts. You gonna kiss me now?"
"Mm." Gray pulled Natsu close to him and grinned. "Nope." He leaned forward and nipped at Natsu's earlobe, then slipped his fingers under Natsu's shirt, running his thumbs down to Natsu's hips.
"C'mon, babe," Natsu whined, then gasped as Gray turned him around roughly by his hips and pressed him up against the dryer. Gray's chest was hot against his back, hands holding him harshly in place.
"Mh-mn," Gray said, biting down on Natsu's shoulder as he dragged his nails down Natsu's back. "Told you, no kisses until the laundry's done." As if to punctuate the point, the dryer began to hum and vibrate, and Natsu groaned, grinding forward against it.
"B-but—" he whined, but Gray cut him off.
"What I am gonna do," Gray growled, nipping Natsu's earlobe, "is fuck you."
Natsu moaned, tipping his head back against Gray's collarbone and reaching up to drag his fingers through Gray's hair. Gray gripped Natsu's hip tightly with one hand, bringing the other up to draw red lines over Natsu's chest.
"The door is open," Natsu protested half-heartedly, and Gray hummed in agreement, slipping his hand into the front of Natsu's sweatpants and wrapping his fingers around Natsu's cock. "Fuck," Natsu hissed, jerking his hips forward as Gray held him tightly across his chest. "S-someone could—"
"I know," Gray said, voice low and rough. "That's why you've gotta be quiet."
"Shit," Natsu groaned as Gray's thumb dragged its way up his cock. "Y-you're... ahh..."
"Didn't I just say to be quiet?" Gray murmured, pressing Natsu harder against the dryer and continuing to slowly stroke his cock. He brought his other hand up to cover Natsu's mouth, and Natsu shuddered. "Can you be good?"
Natsu whined against Gray's hand, pressing his ass back against Gray's cock and enjoying the quiet groan it elicited. Gray let out a shaky breath next to Natsu's ear, then whispered, "If you can't be quiet, I'm gonna have to gag you again."
Natsu gasped, biting down gently on Gray's thumb, and Gray ground against him.
"There you go," Gray murmured, running his thumb over Natsu's lower lip and scraping his teeth over across Natsu's neck. "I know you can do it. You can stay quiet, right, baby?" Natsu nodded frantically as Gray continued to stroke him, slow and gentle.
"What do you think?" Gray asked, letting go of Natsu's cock and moving his hand around to squeeze Natsu's ass. "You want me to get on my knees and eat you out? Get you wet and ready for my cock?"
Natsu hissed through his teeth, dropping his head to his chest. Fuck Gray and his dirty mouth.
"After that, I'm gonna bend you over right here and fuck you," Gray continued, brushing his thumb down Natsu's jaw and resting his hand lightly around Natsu's throat. "I've been thinking about you all day, you know that? Couldn't stop picturing you blowing me in the shower this morning. Your pretty eyes looking up at me while you sucked my cock. Fuck, babe."
Natsu wanted to reply, wanted to say something witty or seductive, but all he could do was whimper as Gray bit his earlobe.
"Shh," Gray whispered in Natsu's ear, then slowly dropped to his knees behind Natsu, dragging Natsu's sweatpants down with him. Natsu gasped at the sudden cold, and when Gray nudged his legs apart, he leaned forward over the dryer and bit his lip to stay quiet.
Gray's hands were cold on Natsu's thighs, running up to his ass and back down again, moving slowly inward and teasing back until Natsu was squirming under his touch. Gray pressed a kiss to the base of Natsu's spine, then moved lower, just shy of where Natsu wanted him.
Natsu was this close to whispering 'please' when Gray finally spread Natsu open and ran his tongue over Natsu's ass.
"F-fff—" Natsu struggled to keep himself from cursing, digging his nails into his palms as Gray's tongue started to move, wet and hot. One hand squeezed Natsu's ass and the other came down to his own pants, tugging them down until he could stroke himself.
Natsu bit his lip so hard the skin nearly broke, swallowing the sounds that were desperately trying to escape. Every noise around him had him tensing, heart leaping with both alarm and anticipation, and he covered his mouth with the back of his arm to keep himself quiet.
Then Gray slipped a finger into him, and Natsu couldn't hold it back anymore.
"Fuck, Gray," he gasped, tipping his head forward and letting out a quiet moan. Gray immediately stilled and Natsu whined, pressing back against him, but Gray ignored him, standing slowly and pressing his chest against Natsu's back.
"What did I say about making noise?" he growled in Natsu's ear, one finger still working its way in and out of Natsu's ass. Natsu whimpered, tipping his head back onto Gray's shoulder.
"I can't, I'm—fuck, y-you…"
"Quiet," Gray said, bringing his free hand up and covering Natsu's mouth. This time, his fingers weren't gentle, and Natsu breathed shakily through his nose as Gray's fingers caught the sounds falling from his lips. "Color?" Gray murmured.
"Green," Natsu mumbled against Gray's fingers.
Gray hummed contentedly. "Good boy."
Gray pressed another finger into Natsu, grinding up against his ass and leaning down to bite his neck again. Natsu panted against Gray's hand, reaching back and running his fingers through Gray's hair, then running his thumb down Gray's throat.
"Mmm." Gray hummed at the slight pressure, then tipped his head down and nipped at Natsu's fingers. "You ready for me? Gonna squeeze me nice and tight while I fill you up with my cock?"
Natsu moaned out a muffled affirmative against Gray's fingers, and when Gray shifted behind him and pressed his cock against Natsu's ass, he couldn't help the needy whine that escaped his lips.
"Fuck, you feel so good," Gray groaned, keeping his hand over Natsu's mouth while the other gripped his hips tightly. He thrust forward, slowly at first and then one smooth motion as he pushed all the way in. "'s like you're made for me, goddamn."
Natsu's chest was tight and he could barely breathe around Gray's hand. Gray let up a little, whispering, "Okay?"
"Yes, fuck, please," Natsu gasped, and when Gray didn't immediately cover his mouth again, he pressed back against Gray and moaned.
"Someone's gonna hear you," Gray warned him, snapping his hips forward and grinding Natsu against the dryer. His fingers tightened over Natsu's mouth again, and his other hand came down to stroke Natsu's cock. "There you go baby, you can do it."
Gray slipped two fingers into Natsu's mouth and Natsu let out a quiet whine, sucking on them as Gray pulled him closer, grinding against his ass. "God, you're so good," Gray gasps, stroking Natsu's cock faster. "So good for me."
Natsu was careening rapidly towards the edge, bucking up into Gray's hand and biting down gently on the fingers in his mouth. Then there was a sound at the door and Natsu gasped, panic flashing through him until he heard a familiar voice mutter, "Jesus Christ, you two."
"Hey, babe," Gray said as Rogue approached them. Natsu tried to turn to look at him, but Gray's grip kept him looking straight forward as he continued rocking into Nastu. "Guess Natsu didn't do a great job of being quiet."
"You're lucky Beatrice didn't walk in on you," Rogue said, and Natsu could hear the fond exasperation in his voice.
"Mm." Gray leaned back and Natsu could hear him kissing Rogue, hand still sliding up and down Natsu's cock. "You gonna join us?"
Rogue hummed, and Gray suddenly pulled back on Natsu's hips, shifting him away from the dryer so Rogue could slide in. Gray slowly moved his hand off Natsu's mouth, bringing it down to Natsu's hip and fucking into him, hard.
"Shhh," Rogue whispered, grabbing Natsu's hair and pulling him into a kiss to catch the sounds he was making. Natsu panted into Rogue's mouth as Gray's breaths quickened next to his ear. He wanted to touch Rogue, but he couldn't focus on anything other than Gray's fingers on his hips and Gray's cock in his ass.
"C'mon, baby," Gray groaned, and Natsu gasped when Rogue's hand joined Gray's on his cock. Gray's fingers came back up to his mouth to keep him quiet and he groaned softly around them. "Come for us."
Natsu shuddered as he came, biting down on Gray's fingers and fisting the fabric of Rogue's shirt until his hands were white. Rogue kissed his cheek and Gray scraped his teeth down Natsu's neck, dragging out the sensation as long as possible until he was whimpering, and his knees felt weak.
"Fuck," Gray whispered as he slipped his fingers out of Natsu's mouth and wrapped his arm tightly around Natsu's chest. "Shit, babe, you feel so good, I'm—ahhnn…" Whatever Gray was going to say was cut off when Natsu reached back and grabbed a handful of his hair, tugging on it hard.
"Your turn," Natsu gasped, voice shaky. "Wanna feel you come."
Gray dug his fingernails into Natsu's chest as he came almost instantly with a low groan. "Holy shit," he whispered as his thrusts turned slow and uneven, then eventually stopped. He pressed his forehead to the back of Natsu's neck, breath hot against his skin as he tried to get his breathing back to normal.
"Well," Rogue said, reaching over Natsu's shoulder and brushing his knuckles across Gray's cheek. "That was…"
"Enjoyable for you," Natsu said, grinning as he slid his hand over Rogue's sweatpants and palmed at his already hard cock.
"Mm." Rogue twitched under Natsu's touch, then pulled him in for another kiss. "Y'know," he murmured against Natsu's lips, "I think Sting would be sad that he's missing out. Why don't we go back to the apartment and invite him to join us?"
"Mm," Natsu said, picturing bright blue eyes and blonde curls spread across the pillowcase. "Sounds good to me."
