Bellybutton Fetish/Tickle One shots [BxB]

Male Reader x Astolfo (Fate/Grand Order Fanfic)

Looking over at Astolfo, comfortably nestled under my arm as we watched TV, I couldn't help but smile. He's so cute, I mused to myself, glancing down at his exposed stomach peeking out from the cropped shirt he wore. He always dressed comfortably when we were alone, mostly in small dresses, or skirts. But I always loved it when he wore the cropped shirts. Exposes his adorable slim belly, with his cute slit-innie. I let my intrusive thoughts win, and I reach over to his stomach. Astolfo was unaware of my approaching hands since his eyes were looking ahead of us.

My fingers scratched the tight opening of his belly button. Astolfo let out a giggle. "Eep, hehe!" He giggled, his stomach contracted back from the touch. "Y/N! Stop!" He laughed, pushing my hand away. I smiled and drew my hands away from his stomach.

Astolfo sat up and turned to me. "Y/N, why are you always trying to get at my belly button?" He giggled. He had a sweet smile on his face.

I blushed. "N-No reason..."

"Hmmm..." Astolfo smirked. He brushed his pink hair out of his face. "I think there's a reason~," He sat on his knees on the couch. "Something about this hole captivates you, doesn't it?" Astolfo arched his back, and puffed his slim belly out, as he poked his navel with a finger.

My face heated up from this. "A-Astolfo..." I whined.

"What? It's pretty clear you got something for my navel~," He said, still toying around in his belly button. "Always poking at it~ and staring~"

I was surprised that he had picked up on this, but he was purposely embarrassing me. So, I wanted to teach him a lesson.

I grabbed him by his waist.

"Eek!" He let out a high-pitched squeak, then, I dug my fingers in his belly button.

"HahahaHAHAHAHA! HEHEHY! NHOHOHO!" Astolfo shrieked in laughter. He tried to push me away, but I just pulled him back by his waist. "Eeep!" He squeaked again. Bringing his waist up to my face, I planted kisses all over his tummy, which, made him giggle even louder. "Y/N STHAHAHAOP!" He laughed, repeatedly slapping my shoulders.

I dug into his sides, and that was probably the end of his vocal cords. He erupted in such loud laughter.

I once again dug my fingers into his navel. His belly button was a slit-innie, so, it was very tight. I had to wiggle and twirl my finger and press with a little bit of force to be able to push it in there.

His belly shook and squirmed each time my finger dug around inside the hole.

Astolfo is still pretty strong, so he managed to break free from my tickle attacks.

"Oh... oh my... " He hunched over, laughing still. "You dork..." He laughed, "That tickled!" He quickly shot up and shoved my shoulders.

I laughed. "That's what you get for teasing me~," I playfully stuck my tongue out at him.

Astolfo rolled his eyes. "Yeah whatever weirdo~," He smiled. He came closer to me and kissed my cheek, making me blush. Smiling, and reached over and poked his belly, near his navel. He giggled. "Hehehey! Not again!" He smiled.
