Tongue
"Truth or Dare?" Loke asked Natsu. The small group were splayed around Lucy's homie living room. Team Natsu, (which included Lucy's spirits if they were present - hence Loke), Gajeel and Levy were seated on Lucy's plush carpet, all waiting to hear Natsu's answer.
The pinkette sat in between Erza and Gray, the latter's side he was attached to. "Mmm..." Gray stared down at the boy glued to him with a small smile. "I pick Truth!"
"Pussy." Gajeel's gruff voice sounded.
"I like dicks, thanks." came Natsu's snark reply. The iron dragon slayer rolled his eyes while Gray smirked.
"My ears you guys!" Levy complained.
"Okay okay! Shush everyone, because we're about to know what body part Natsu likes most on Gray!" Leo smirked as several gasps and squeals filled the room.
"Isn't that a bit personal?" Lucy asked with a sweat drop.
"No." Loke, Erza and Gray uttered, all staring at Natsu who squirmed under the attention.
"Look, we already know he's into dicks. Gray's a dick, we got it. Let's move on." Gajeel grumbled before being knocked over by Erza.
"I feel as if this piece of information will do well for me in future black mail." the Queen of Fairies declared.
Lucy sweat dropped again. "Um."
"Well, Natsu?" Loke pushed.
Gray stared at his boyfriend who looked cute all deep in thought.
"He's actually thinking about it." Lucy's comment to herself was half a question and half a statement.
Natsu seemed to have gotten lost in his thoughts for his eyes had glazed over. Leaving the present, the pinkette's memories brought him back in time after taking in the word he'd silently chose as his answer for Loke.
Tongue.
Natsu trembled in the older boy's arms as a set of cool, moist lips were wrapped around his neck and sucking softly. Hands gripped his slender hips, holding him close as they massaged his revealing skin.
Gray moved his lips up the dragon slayer's neck while his tongue slowly came out to trail a line of clear spit up the soft flesh. Natsu squirmed and whimpered at the feel, heart racing in his chest when Gray moved more up his neck, sliding his cold tongue under the pinkette's jaw.
Natsu held onto Gray's shoulder, body hot all over as he felt the tongue slip closer to his quivering lips. Gray paused when he reached the corner of Natsu's bottom lip. The boy in his arms went still and Gray pulled away just enough so he could stared down at Natsu's blushing face.
The pinkette looked edible with his lips parted, wet and slick looking. His face held a soft hue, hair disheveled with some pink patches flopped in part of a doe eye, watery and dark with innocent lust.
Gray thumbed Natsu's lip before grasping his face and leaning down, claiming them the soft lips as his. He expertly moved the pinkette's lips with his own, earning him soft mewling sounds. He sped the kiss up switching from Natsu's lower lip captured between his mouth and his lower lip between caught in between Natsu's. Slowly but surely their mouths began slicking up with spit and their breathing became mingled as one breath.
Natsu tried pulling away to breathe, parting his lips to take a gulping batch of fresh air but Gray kept a lock on his lips. The pinkette gave a slight push to Gray's chest yet that only resolved to Gray prying his mouth open for his tongue.
Natsu let out a gasp, eyes wide and staring up into Gray's laughing ones. The black haired boy kept eye contact and slowly searched every sweet corner Natsu's wet cavern had to offer with his tongue. Natsu's eyes watered and began falling shut from all the pleasure his body was feeling. It all intensified when Gray snagged Natsu's tongue around his own and pulled into his mouth sucking.
"Mmm~!" the pinkette cried out, the sound coming out muffled like. Natsu pushed himself more into Gray, wrapping his arms tightly around the older boy's neck and tilting his head to the side.
Gray had his tongue wrapped around Natsu's and sucked slowly, profusely, in a languid manner. Natsu quivered in his arms.
"Natsu?" Lucy.
Natsu's trembling legs were spread wide and his rear end was lifted slightly off the bed as Gray leaned forward and pressed his mouth against the drenched hole before he slipped his tongue inside, the entrance constricting around his apendage and pulling him in.
"Uhn!~ N-not th-there Gray!" Natsu weakly tried to push Gray away but the way the tongue moved inside him, brushing against his sensitive walls, licking against that spot, he just fell back down on the bed breathing labored breaths.
A small shriek left the weak man's mouth when he felt teeth glide over his quivering entrance. Lips wrapped around the wet hole and sucked before that tongue cleaned up the spit.
"Oi, Natsu!" Loke.
"Ah ah ha ah huhn~!" Natsu whimpered out as he thrusted down on the finger inside him. He was flat on his back with Gray next to him slightly hovering above his body. Gray's lips were busy at Natsu's sensitive neck, tongue flickering out every so often as he continued his ministrations on the boy. While he dined on the sweet tasting neck, Gray felt something wet and slick slide down to meet with his busy lips. He paused and glanced up to see Natsu's head thrown back with his mouth open and a waterfall of saliva seeping out.
"Baby, you're making a mess.." Gray purred and licked up the trail of spit until his tongue entered the drenched cavern. As he did, he jammed his fingers against Natsu's sweet spot making the boy arch into him and mewl.
"NATSU!" Everyone.
Natsu blinked. Still in a slight daze, he looked around the room to find his friends and boyfriend all staring at him.
"Are you okay?" Lucy asked looking concern. "You don't have to answer-"
Natsu could feel a problem down below and blushed hoping no one noticed. Except they all had- minus Lucy and Levy who were too concern to even think it be that.
Gray brushed his fingers over Natsu's very warm cheek, eliciting a moan. The pinkette blushed and rushed out a few incoherent sentences that sounded like "His fucking tongue" and "Game is over for us Gray" before grabbing Gray and hauling him up and out the door.
Loke bursted out laughing followed by Erza and then Gajeel. Lucy and Levy were utterly confused.
Meanwhile at Gray's place, Natsu was reliving his flashbacks.
