Chapter Text
Killua finds himself with a free evening, after weeks of tracking a blacklist criminal with Gon. The hunter was looking forward to spending his night relaxing and pampering, starting with a long and hot shower. He felt his muscles begin to relax as the water cascaded over his body. It felt good to close his eyes and just bask in the steam of the shower. He began to wash his hair and he could feel his muscles began to relax even more as he massages his scalp. Although he loved being on missions, it was always nice to take some time out for himself.
Killua’s thoughts began to wonder as he rinsed his hair and started to apply conditioner. It seemed as he never had the chance to pamper himself. Gon always teased him for being too “high maintenance”, however, he never seemed to complain when he dressed up for him.
Killua reached for his coconut body scrub and applied it to his loofah and began to gently scrub the grim off his body. It felt as if he could feel the dead skin being removed from his body. Now that he and Gon had some time off, it would be nice if they could go on a date night. Speaking of Gon, he heard the front door being closed meaning Gon must be back from the store.
Just in time, Killua thought as he reached to turn off the water. As he was stepping out the shower and onto the tile, the door opened. He reached for a towel and wrapped it around his waist just as he looks up to see Gon walking through the door.
“You couldn’t wait?” he huffed, looking into amber eyes. Although, he knew asking was just a waste breath. “I haven’t even moisturized, Idiot” as he saw Gon’s eyes slowly rake down his body. His eyes were full of lust and intent as he stared.“No” Gon murmurs, before closing the distance between them and mouthing at his neck.
“Stop it, I just got out of the shower” Killua says without any heat. He leans his head to the side giving Gon better access to his neck. He nips at his collarbone softly before biting hard enough to leave a small bruise. Gon licks at it apologetically and Killua knows he has lost this battle. When he lets out a breathy moan, he can feel Gon smirk against his neck. He leans down until he and Gon’s lips are aligned and licks Gon top lip teasingly and pulls away.
Before he could get too far, Gon threads his fingers through his still wet hair and tugs his face back down to kiss him deeply. Gon’s kiss is insistent and demanding. He feels one hand start to trace down his back allowing his nails to gently rake down his muscles of his back to his sides before settling right below his navel to tug at his towel. Killua moves to clutch Gon’s shoulders as he feel the towel drop to his feet. He open his mouth to protest, but only lets out a moan as Gon presses a clothed thigh between his legs.
Gon moves to place soft kisses over Killua’s face and Killua lets his head fall forward as Gon presses closer. He almost missed the smug look on Gon’s face. In retaliation Killua, simply ran a sharped nail down Gon’s chest ripping his shirt the process. “Jerk” Gon mumbled against his temple. “You deserved it and plus I’m the only one who’s naked” Killua replied.
Gon kissed him hard, effectively shutting him up. Killua’s hands slid over Gon’s bare chest as they kiss before stopping to pinch and twist a nipple, gently. Teasingly.
Gon gasps at the feeling, breaking the kiss. ”Killuaaaa” he breathes. “You like that?” Killua responds as he tugs at his nipple again. Gon hands move from his waist to grip his ass pulling him close and trapping his hand between them.
“Yes,” Gon moans. “Killua, let me fuck you,” He says, voice deep and husky. Killua shivers as he hears the need in Gon’s voice. “Please Killua,“ and that was all it took to Killua to swallow hard and nod his head in agreement.
Suddenly, Gon’s lips were back on his, and Killua’s melts into his touch. He knew just how to push his buttons to make him let go and turn him into putty in his hands.
Gon’s hands find their place on Killua’s bare hip and the small of his back pulling him close. This kiss is long, sensual and deep and by the time they pull away, they are both breathless. “I still think it’s unfair that I’m the only one naked.” Gon only chuckles in his ear. “So impatient. Let me enjoy you. Your skin is soft, I can’t get enough.”
Gon pulls away. His hands and mouth are gone, and Killua huffs in annoyance. Before he could say anything, he is being flipped around and Gon is pressing his body against Killua's damp back. He leans in, biting the juncture between his neck and shoulder, causing him to groan.
“Gon…” Killua moans as Gon soothes the bite with his tongue and kissing his neck. He can feel Gon’s erection through his clothes and he is ready to move on to the main event. He grips the countertop as Gon continues the assault on his neck. “Bedroom. Right Now.”
Gon makes no movement and simply mutters “No.” and holds Killua in place. As Killua sees Gon’s smirking face in the mirror, he knew he planned this all along. “Freak” he accuses, but leans back to kiss him anyway.
The kiss is rough and messy. Almost too much teeth and not enough tongue, but it was perfect. Killua can’t help but blush when they break apart and sees all the steam has cleared from the mirror and he can see his hard cock against his stomach and Gon pressed against him and his eyes half lidded and full of desire. Suddenly Gon is pushing his pants down, pausing briefly to take the bottle of lube out of his back pocket.
He is then using one hand to press between Killua’s shoulder blades causing him to lean down onto the counter. Killua complies with the unspoken request and moves to grip along the sink and lifting his hips slightly when Gon presses two slick fingers against him. His touch, gentle and teasing, and he thrust backs on Gon’s fingers. Gon moves to his hand down to the small of his back and holds him in place. “My pace,” he says.
Killua stills and lets him move as slowly as he likes, taking his time in preparing him. He feels his fingers inch inside deeper and deeper. Letting out a deep breath, eyes fluttering closed, and lifts his ass up into Gon’s touch.
Gon crooks his fingers inside him to brush against his prostate and it’s just enough to drive Killua crazy. He can feel himself getting hotter and a thin sheen of sweat start to coat his body as Gon slowly works him open. Soon a third finger joins the other two and Killua is trying to roll his hips back against Gon’s hand. “Hurry up, Gon. I’m ready.”
Gon is moving the hand on Killua’s back, reaching forward to cup his face from behind, tilting his head up, so when Killua opens his eyes he can see his face in the mirror. The hungry look in Gon’s eyes sends a pooling heat in his stomach.
“Damn it, Gon” he mutters. He catches his own reflection in the mirror, mouth parted, pupils blown wide with lust, silver hair falling in his face, and gasp, before glancing back up to Gon. Gon, with his eyes low and hazy.
“Look at you,” He whispers and leans in, brushing his lips against the nape of Killua’s neck, then locking eyes with him in the mirror. He rests his head on Killua's shoulder, letting out a deep, shaky breath.
“So beautiful” Gon continues, and Killua can’t help but whimper as Gon crooks his finger again, stretching him easily. He can’t look away from the image in the mirror. His skin is flushed and cheeks red, with Gon’s fingers pressing into his ass. Then there is the look, on Gon’s face like he is almost ready to devour him.
It isn’t until Gon pulls his fingers out that he releases Killua’s cheek, and allowing him to slump against the counter. Killua eyes finally close as his rest his cheek against the cool marble, lifting his ass up towards Gon.
Gon presses his cock just barely against his puckered hole but doesn’t push in just yet. He rests it there teasingly. Killua tries to press his hips backwards but Gon moves away slightly.
“What do you want?” he asks and Killua doesn’t have to see his face to know he is smirking. Gon loves it when he pushes him to the point of begging. It is so unlike him to let go and give up that control.
“Fuck me. Please, Gon,” He groans. At that Gon seems to snap and is thrusting into Killua roughly and all at once and he can’t help the way he arches his back, lifting his head and crying out at the sudden movement. Killua loves it when he fucks him like this. When he can feel every inch of his cock and press of his hips.
Gon waits for a moment allowing Killua to adjust to the sensation. Killua presses backwards onto him, fucking himself shallowly on his cock. That signals Gon to finally move, he moves one of his hands from Killua’s hips to pull his hair, forcing him to arch his back and to take his cock deeper.
“Look at yourself” Gon growls. He opens his eyes and glances in the mirror, making eye contact with Gon. He shudders as his gaze burns into him. “You love my cock, don’t you? Gon murmurs as he watches Killua’s reflection in the mirror. Watching the way he thrust into him and how Killua’s mouth goes slack as he thrust into him slowly, making him feel every inch, before slowly pulling out, only to do it again.
“You love how it fills you up, begging me with your eyes to fuck you harder.” Gon continues as he starts to pick up the pace, still fucking him deep and hard. Killua is mesmerized by their reflection, unable to look away.
His flushed face, sweaty skin, hardened nipples, and his cock hard and leaking against the counter. Then Gon’s face as he moves against him. The way his eyes alternate between his face and his ass, without a doubt watching how his hole stretches as he fucks him. The way Gon’s face is lightly flushed and pinched in concentration, eyes almost black. Killua moans at the sight and rolls his hips back to meet each thrust.
“Fuck Killua, you feel so good. So beautiful.” Gon says, his voice rough and thrust becoming faster. Killua can’t stop the whine that escapes, sounding low and needy. Gon angling to hit that spot inside of him, causing him to moan louder.
He feels as Gon leans down to press gentle kisses against his shoulders and neck, still fucking him at a fast pace, hitting his prostate.
“You must be getting close. I can feel you tightening around my cock,” Gon whispers in his ear, his voice smooth and dark. “Come on, Killua. Come for me” Gon coaxes, his teeth biting into his neck hard enough to bruise.
The pain pushes Killua over the edge, and he is coming, back arching, head thrown back, all while screaming almost silently. Gon’s thrusts into him faster as his muscles tighten around him, and a few seconds later Killua feels him shooting his cum deep into ass and filling him up.
Gon relaxes, letting go his Killua’s hair and slumming against him. His body warm and heavy as he drapes across his back. For a moment, neither of them move, other than Gon running his hand soothing across Killua’s skin.
Finally, Gon pulls out and steps away from him. Killua turns to find Gon smiling at him with a lopsided grin. “You pervert,” Killua accuses him teasingly. Gon chuckles and takes a step towards him and brushes his lips across his forehead. “I didn’t hear you complaining,” He quips still smiling.
“True,” He agrees. “Now I am going to have to get clean again, though.” He moves past Gon to bend over the tub and turn the water on. He spares one long glance at Gon before stepping into the shower. “Aren’t you going to join me?” He says as turns his back to Gon to let the spray wash over his body as he heard the curtain close as Gon get in behind him.
