He helps Grey, and asks for some help in return

"Maybe you just need some more simulation. Your dick is not your only sensible spot, you know?" He said as he started getting closer to Grey. "Wait! You don't have to do that, Natsu!" He replied. "This is my problem, a personal one, I can't ask you to do something like this for me."

"We're friends, aren't we? Of course I have no issue lending you a hand or two when you need it!" Said the pink haired mage as he made his way around the table to position himself right behind Grey. He surrounded him with his arms, using his right hand to pinch and play with his friend's nipple and his left hand to slightly caress his balls while he kept working his shaft up and down. All glimpses of resistance quickly fade away, replaced by pleasure, moans, and grunts. Natsu started sensually licking his friend's neck, to which he started squirming, still unable to cum. Not until Natsu said the magic words.

"White release"

Streams of semen quickly ejected from his cock. Most of them ended up in his abdomen or on his and Natsu's hands, but some of them were powerful enough to reach his chin and even his hair. He remained there for a minute trying to regain some strength, mostly motionless except for the movement of his chest caused by his heavy breathing. "I already said so," he started as he caught his breath "but I am sorry about all this. But thank you for all your help, I swear I'll make it up to you. For now, I'm just glad this is over."

Hah, you wish.

"Well... maybe you can make it up to me now?" Said Natsu pulling his pants down and revealing his massive erection. "I helped you out, how about you do the same and we call it even?"

"Wait, Natsu, we can't..." Replied Grey, even though he was unable to take his eyes away from it. "We're not that kind of friends. What we just did must remain something exceptional. It was probably the result of a curse or something. And we also need to eat and get going, we've already wasted too much time and we have..."

"Oh, come on." Interrupted Natsu, "I saw how you were looking at me. We both know you want to get your Hands-On Natsu".

The ice mage quickly dropped to his knees in front of his friend, his face right next to that throbbing dick. "Fine," he said as his hand started working on Natsu's shaft, "I'll repay the favor quickly and we can move on from this and never ever mention it again." He couldn't believe he was doing that. And even worse, he was starting to enjoy it. The more he thought about the situation, the hotter it got for him. He was down on his knees, pumping his best friend's dick, which was no more than two inches in front of his face. God, he could smell Natsu's cock, and that just made it hotter.

He could feel himself getting hard again. He started moving his hand towards his dick, but Natsu took notice. "Ah, I see you're also going Full Mast again". Grey's hand stopped immediately. What was he going to do with it again? Never mind, he had to finish off his friend and find a way to get off himself before the situation could get even more out of hand (pun not intended). To that end, he gradually increased the speed of his handjob.

"Come on, Natsu." He said as he furiously stroked his friend's erection. "Just cum already! We got things to do!"

For Natsu, the sight was glorious. Grey covered in his own cum with a raging hard on vigorously working his dick with his face so close to it he was probably going to get it covered in white. That was starting to get a bit too much to handle, but he didn't want to cum just yet, not before he tried something else. "Well, maybe I would cum faster with some Lip Service."

Grey knew exactly what he needed to do. He was already thinking about it anyway. He got his face even closer to Natsu's crotch, and started by timidly licking his tip while continuing with his strokes. As he gained confidence, that lick turned into a kiss, that kiss into getting the tip into his mouth, that into sucking and licking the entire side of his dick with lust, and, eventually, into a full-on facefuck, with both of Gret's hands firmly holding Natsu's ass.

With that display, Natsu was unable to hold for much longer. "Let me cum on your face!" He screamed, to which Grey responded obediently by taking Natsu's member out of his mouth and pumping it hard once more, positioning his face to catch as much semen as possible, and the semen didn't take long to drop in it. As he came, Natsu screamed at the top of his lungs "Grey Nutbuster", making the ice mage also release another load on the ground at the same time his friend's cum was making contact with his own face.

"Well, that was certainly something..." he said, while Natsu considered what to do next.
