Gray's POV:

I pushed my member up against Natsu's hole. It was as tight as I remembered, but I started shoving it in anyways. I felt Natsu contract around me, and he cried out in shock. He must not have been expecting it to hurt like this... Maybe I should have stretched him out first. Oh well. I'm sure it'll be fine. I kept on pushing and pushing, until I was buried deep inside of Natsu's ass.

"Myaaah~!!" Natsu moaned and squirmed underneath of me.

I grunted into his nape. "Does that hurt?"

"O- only a bit," Natsu said. "D- don't stop though. It's not that bad, I-I can handle it."

"Are you sure?" I asked, slightly worried.

"I'm s- sure," Natsu said. Smiling, I began thrusting slowly. The pace was so slow, it was more like I was just shifting back and forth. I repeated this action, and soon, the inside of Natsu started becoming wetter, and more slippery. I quickened my pace a bit.

To fulfil my desire to make Natsu feel good, I reached one hand down to Natsu's erection. I gripped it tightly and started to stroke him generously. I matched my hand movements to my thrusts. Both of our moans and other sounds got louder and louder, and the sex slowly transitioned from slow and careful to desperate and messy. I was nearly at my limit, and judging by the sudden increase in Natsu's voice, he was as well. I moved faster, building both the friction and the pleasure. A pit formed in my stomach and soon came, filling him up. Natsu came soon after me, spilling out between my fingers.

We were both grunting and breathing heavily. I unsheathed my sword from his now dripping wet ass and collapsed onto the bed beside him. Natsu lied down next to me, no doubt covering himself in his own semen, but he didn't seem to care, and he smiled at me.

"I love you," he said in his sweet voice.

"I love you too, Natsu," I said. I gently kissed him, before wrapping my arms around him, holding his warm back against my sweaty chest. I fell asleep lying there. Next to Natsu.
