Chapter 14: Natsu/Gray - "Earth-Shaking"

The bed squeaks in constant rhythm, in time with Gray's breathing where he's flung his head back over the edge of the mattress. His legs are hiked up and under Natsu's control, and Natsu has his eyes closed, thrusting into Gray over and over.

"Fuck," Natsu says, leaning over him on one hand. "Fuck…"

Gray just moans, head tipped back and throat on display.

As Gray lets loose a string of strangled encouraging sounds, Natsu tips down and nips at his neck, feeling the bob of Gray's throat under his teeth.

"Na…tsu…" Gray whimpers, but Natsu sucks at the divot of his throat and stops up his words.

By the time he's any semblance of communicative again, Gray is shaking.

"You—hahhh—the way you fuck me and…oh my gods, Natsu…"

Natsu jerks at the tone of his voice, which shoves his cock deep. "Fuck, I'm gonna—"

He breaks off as Gray moans yesss, and then he grips Gray's hips hard as he pulls Gray's ass to him, onto him, as deep as he can fit, and lets it all go.

Gray sighs and relaxes onto him as Natsu finishes coming. His muscles are shaking hard from clenching, and his cock is red with need.

For a few blissful seconds, they both pant hard, Natsu pulling out slowly—Gray winces then relaxes—and the pair of them make eye contact. Gray's expression is still on edge, hopeful and needy, and Natsu ducks his head to give him a gentle kiss on the lips.

"I haven't forgotten about you," he whispers.

"I never thought you did," Gray says. He runs his hand up into Natsu's hair, framing his cheek, so tender even though his pulse is still thrumming through his muscles.

Natsu loves the gentleness of their romance. He also loves the taste of Gray's cock, and it's bobbing between them: he can't help reaching down and stroking it, appreciating Gray's shape and size and thumbing down his foreskin a little.

Gray swallows and gives a little groan.

When Natsu leans down, he touches his tongue lightly to just the tip of Gray's cock, still eliciting a gasp as his warm breath makes Gray's cock jerk in excitement. Pulling his foreskin down more, Natsu sucks his tip between his lips, and in that sudden pressure, Gray lets out a shout and thrusts his hips up.

Natsu knows him, knows he's going to do this, so he backs up with Gray's hips, keeping to just his tip, and Gray begins to whimper his name, "Natsu…Natsu, please…"

And still Natsu keeps sucking his tip, occasionally swiping his thumb over him and enjoying every guttural sound that comes out of Gray's raw, teeth-marked throat.

When Gray sounds like he can't take it anymore, like he might just come from this alone, Natsu swoops in and takes him deep, making sure his tongue grates along Gray's cock.

Just like that, Gray comes. Natsu grabs his hips as he does, stabilizing him through it, while Gray gasps and cries and calls his name.

"Natsu," he says. "Natsu!"

"Yeah," Natsu replies. "Just like that, love. Just like that…"

Slumping, Gray collapses in Natsu's arms and Natsu lowers him back to the bed, sliding up until he covers Gray's body with his own.

"Hey," he whispers, staring down at Gray's closed eyes.

His eyes flutter open dreamily.

"You falling asleep?" Natsu asks, stroking Gray's hair.

"Mmm," Gray groans.

Natsu smiles and kisses his lips.

"Taste like cum," Gray mumbles.

"Yes, I do," Natsu says, proud, and that gets Gray to chuckle.

"Come sleep with me?" Gray asks, already closing his eyes again and wrapping an arm around Natsu's shoulders.

Natsu sighs contentedly and snuggles up against his side.

"Yeah," he says, kissing Gray's neck. "I'd love to."
