I Swear On My Fire Fire Fruit.

"Ace?"
"Huh?" He looked up at you from his spot at the table, watching as you hopped up next to his plate of food. A blush crept across his perfectly freckled cheeks as he realized what you were wearing.
"How do you like my outfit?" You snickered. He swallowed his food and looked you up and down, noticing your black cargo shorts and yellow bikini top, an orange hat atop your head and black lace-up boots snug against your feet.
"You look just like me." The devil fruit user smirked and leaned back in his chair. "Well, a girly version of me at least." A giggle erupted from your lips ad you leaned in, kissing the tip of his nose and taking in the heat of his blush.
"So do you like it?"
"I love it." You and Ace had been crew mates for almost two years now, and you had developed a crush on the boy the second you laid eyes on him, but were too scared to mention it. You brushed his long black hair out of his eyes for a moment, staring down at him.
"Ace...can I tell you something?"
"Hm?" His hands travelled to your back and made soothing patterns across it, turning you so your knees were against his chest and your feet rested on his thighs.
"I...I really like you, Ace...and, well...I was wo-" suddenly he slammed his lips against yours, pulling you off the table and into his lap.
"I thought you'd never confess." The man laughed, leaning in to give another loving kiss against your soft lips. His kisses were gentle, but his lips were warm with the heat of his fire fire fruit, acting as a furnace in the pit of his being and sending waves of heat across his skin. Your arms wrapped around his neck, your slender hands tangling in his thick hair, his own hands resting on the small of your back. He opened his mouth slightly and licked your bottom lip, silently asking for entrance to the new area. Without a second thought, your mouth opened and his tongue shot forward to explore, pressing deep into the edges of your cheeks, causing a moan to slither out and mix with the heat of the kiss. Ace sucked your tongue from it's hiding place, pulling it into his mouth and biting gently, savoring the sweet taste of it. Your head began to throb alongside your lungs, screaming for air, but your hands refused to let go. You opened your mouth to pull away, only to find out that you couldn't.
"Ace?"
"Hm?"
"I uh...I want my tongue back." He smiled at the sound of your giggle, gently holding your tongue in between his teeth.
"Nah. It's mine now." You wondered how he could even speak correctly, but it didn't matter right now. He pulled his head back so that your head would fall forward, releasing your tongue at the last moment and using the momentum to grab your lips in another heated kiss. But the heat wasn't just from his fire fire fruit now. It was the spark of love that had silently been growing in both your hearts. At last the two of you pulled away, panting and grinning and holding your foreheads together to look each other in the eyes.
"I've loved you for so long, _." He smiled.
"Really?"
"I swear on my fire fire fruit." You laughed and leaned in, landing a gentle kiss on his lips.
"I love you too."
