Natsu couldn't take it. Gray was moving unbearably slow, which didn't help to soothe his heat at all. Gray was supposed to be helping him, so why was he taking his precious time? Sure, Natsu enjoyed the way Gray was moving so slow and tenderly, but he was in heat. He didn't need slow and tender, he needed fast and rough. With the ice mage going slow, Natsu's senses were completely overwhelming him. He was only focused on Gray. He could only feel Gray, could only hear Gray, could only smell Gray, could only see Gray, and could only taste Gray. There was nothing but Gray to Natsu.
"Gray, f-faster. Please..." Natsu moaned.
Gray pinned him with a slight glare. It was so familiar that Natsu almost forgot the situation they were currently in. "No. I'm going to do this at my own pace, and you're going to enjoy every second of it. You won't be able to forget the way I felt after I'm through with you." He growled out.
Natsu gasped at his words. Who knew Gray could talk so dirty? "I-I want it." He whined.
Gray smirked and pulled his fingers out of the pinkette. He left a trail of kisses from Natsu's neck to his naval, stopping right before he reached his aching cock. "Of course you do."
Gray grabbed the submissive's member, running his cold tongue from the base to the tip before engulfing it in his icy mouth. Natsu's hips thrusted into Gray's mouth against his will, and a loud moan left his mouth. Gray loved the noises coming from the fire mage. He continued to suck him off, coaxing a few more sounds from Natsu. His lips parted from Natsu's dick with a 'pop'. Natsu whined at the loss, but it was soon replaced with a needy whine as he felt Gray's tip enter him.
Gray impaled Natsu with a single, slow thrust. He watched the dragon's face as he did so. The expressions Natsu wore during sex were so erotic! Gray could barely contain himself. The ice mage took a deep breath to calm himself as the dragon-slayer's hole engulfed his cock. He was so tight and warm! The feeling of being inside the fire user drove Gray crazy.
Another whine left Natsu as Gray began to move, slowly thrusting in and out of the dragon. Gray was doing all he could not to cum so fast, but the dragon-slayer definitely wasn't making it easy for him. He was just so sexy! Gray's moans joined Natsu's as his thrusts became faster. He hit a sweet spot that had Natsu arching his back off the bed in ecstasy.
"D-Do that again!" Natsu shouted, and Gray couldn't find it in him to deny the pinkette.
He did as he was told, angling his hips so that he abused the dragon's prostate with every thrust. The submissive became nothing more than a writhing, moaning mess under him. He had lost all control, and had completely given in to the heat. The sight turned Gray on even more, if that was even possible.
"N-Natsu, I'm going to..." Gray moaned as he felt his orgasm building up.
"Wait!" Natsu's panicked voice snapped him out of his daze and he slowed his thrusting.
"What's wrong?" Gray asked, worried that he had done something wrong.
"Don't cum inside of me. You're not wearing a condom, are you?" The dragon asked.
Gray was confused. "No, why?"
Natsu smiled reassuringly. "It's nothing bad, I promise. Just trust me, okay?" He pleaded.
Gray nodded, still confused. "Okay." He pulled out and jerked them both off until they came.
*****************************
Gray was laying on his side, staring at Natsu with a puzzled look on his face. Natsu, of course, noticed this and turned to his side as well, facing Gray. "Why didn't you want me to cum inside of you?"
Natsu smiled. Gray was cute when he was curious. "It's mating season, and I'm a submissive dragon-slayer, so that means I can get pregnant."
Gray's eyes had widened comically, and Natsu laughed at the sight. "You do know you're a guy, right? I thought guys couldn't get pregnant."
Natsu flicked him on the nose. "They can't, but male dragon-slayer's can if they're submissive. Only during mating season, though. If it was any other time, I wouldn't have to worry about getting pregnant." He explained to the ice mage.
"That makes sense, I guess." Gray agreed, a look of wonder on his face.
"You think too much, popsicle dick."
"You don't think at all, flame brain."
Just like that, everything had gone back to normal. For once, they were both glad. It was reassuring, knowing that a change as big as this couldn't ruin the friendship and trust they had built.
