Disclaimer: I'm trying to make it realistic so for now the swearing and super crude language is at minimum until Natsu is more experienced. Like always I own nothing. ENJOY GRAYXLUCYXNATSU finally.
The two men walked down the familiar street together, close enough to feel the hot and cold collide. Natsu was walking with limp due to the fact he watched Gray change and something about inspecting his sculpted body turned him on. He almost wanted to pounce on him and take him right there but he really was worried about Lucy. They were passing her house when Natsu stopped in his tracks. He smelt her. It was over bearing. It was accompanied by that sweet smell from earlier. This made his heart race and his hormones went crazy.
"She's at home, I know it." Natsu was gravitating towards her door but Gray put his hand on his shoulder.
"Then why don't we surprise her" He motioned upwards towards her bathroom window, Natsu was hesitant after the fact they almost got her raped and maybe even killed, But it would be faster so he agreed and the boys shuffled up the tree. Natsu obviously being the first one peered in and saw Lucy in the back. Her eyes were closed. Holy shit is she hurt of dying, she sure looks in pain. He eyes moved further down. Her chest was shaking in a rhythmic fashion. He continued down to see her knees buckled in and becoming wider. She began panting and moaning, and finally it clicked, she was um pleasuring herself? I wish I knew the name. Gray would know. He finally caught up and saw what I was watching. Gray raised his hand and smacked the dragon slayer. Natsu was taken off guard.
"Well you really are a pervert huh? This will be heads up for next time, don't watch unless you're the audience. Hey Luce!" Gray summoned Lucy as if he was using her keys. Lucy opened her eyes. Already irritated, but instead of getting mad the flushed stayed on her face and she moved to the edge of the bathtub to the point where her tits were just barely covered. She gave a smile that included a hint of mischief.
"So we really need to talk guys, and Gray while we all talk you can give me a nice full body massage." She smiled, got up out of the tub, and walked naked to the bedroom. Both of the boys staring hard. Gray gave a large sigh as if it was a choir to touch Lucy's porcelain body when Natsu would've easily jumped at the chance. Gray entered the window and Natsu followed. They walked in to an naked Lucy propping her head, on her stomach. Even her backside was sexy. Gray got on top of her legs and straddled them. He moved his hands to her shoulders and started kneading them. Natsu pulled up a chair across from them. Feeling embarrassed that he had become so hard so quick. Gray noticed the wounds on her back but didn't want to risk making her upset by bringing it up.
"So are you two a thing because that would be insanely hot, but i'd get quite jealous" She giggled at a scenario that was quite serious to Natsu.
"I'm teaching him the basic's, and by the way flame brain, where'd you learn to suck dick like that?" The words made both Lucy and Natsu feel a shot of pleasure into them.
"Well I um, watched Levy and Lucy do that to um, banana's so I copied what they did." Natsu was becoming increasingly embarrassed to the point of no return.
"Really, a dick suck off. I mean you're great Luce but hot head blew me away" He cracked up at his own joke. The blonde kicked her foot up into his spine. She smiled and he groaned in pain.
"Now you're going to pay-" He flipped her over. Lucy giggled as he picked her up and flipped her over so her legs were facing Natsu. Grey walked to Natsu, stood him up and pulled him in close. He shoved his cold tongue into his hot mouth. He was so aggressive. he noticed that he had already stripped. And that his dick was aching as well. Natsu thrust into him to even relieve the slightest bit of pressure. But Gray pulled away and pointed to the girl sprawled out on the bed, dripping on the sheets.
"So buddy, you can take the bottom, as long as I get the top, got it? And you can do whatever you want with her pussy, but have fun." Gray stripped his boxers and cradled her torso. He had been waiting for this for far to long. Natsu spread her legs apart and took in the intoxicating smell before giving her clit a small lick. He kept licking trying to taste as much of her as possible at once, and the more he licked the more that came out. Gray was watching the reaction. She moaned loudly and squirmed under the ice mage. Gray was just fascinated by how she felt so good from Natsu's touch. That he didn't even know how hard he was. It was resting in between her silky breasts. She pushed them together as an invitation for Gray. Without any hesitation he began thrusting into her as she licked the tip every time it reached her face while Natsu was still lapping her cum up. He noticed where it was coming from and stuck his tongue in her tight hole. She screamed loudly and all at once came all over his tongue. When she opened her mouth Gray accidentally thrust to far and it went into her. She sucked hard once and that was all it took for Gray to release himself all over her face and chest. He collapsed on her panting. Their chests moved in sync as they came down from their high, but then they realized someone was missing. Natsu was just sitting at the edge of the bed, stunned by what he experienced.
"Lets teach him the golden rule of orgasms" Gray whispered into Lucy's ear. She nodded and they adjusted themselves onto the edge of the bed.
"Okay Natsu it's time you learn about masturbation. I'd give yo a tutorial but someone made me cum too early, so we'll show you what to do with yours." They got on their knees infront of him. Lucy lowered his pants over his hard on. Gray started moving his hand up and down his hot shaft. Earning a reaction from him. He stopped immediately.
"So basically just do what feels good to you. Rub the tip, stroke your balls, whatever you want man. So try it on your own." They sat their waiting for him to start.
"With you guys...watching" Natsu was blushing at the thought. He has had dreams of him cumming but never touching himself. They just nodded and waited. Perverted piranhas. He reached down and grabbed his erection. It sent a surge through him because he had been holding on for so long. He needed to cum. He didn't hesitate and rubbed up and down quickly. Feeling it twitch the closer he got. Everytime he touched the head he'd let out a moan. Making the two on the ground aroused. He moved faster desperate for an orgasm. Lucy licked her finger and rubbed his tip. Which pushed him off the edge. He released all the pent up pressure he had been holding in all day. But since he didnt see where he came he looked down at the two who were now covered in his cum.
"Cool so now you learned the golden rule, I have a mission for you two, and i'd do it myself but you two did fuck up our last mission so nah." Lucy got up a plopped down on the bed.
"I want you two to find us a mission. Then after that I want you to visit a store and pick up some specialty items." She sat up and smiled at the worried boys.
