Onii-San!

Ok, this is my first attempt at writing. It took about 15minutes, so it isn't very graphic or detailed. Just a simple/short story. Hope you enjoy!

“Onii-san!”

She cried as her brother ran ahead up the beach.

“Come on sis, you can do better than that!” he replied, watching her struggle to catch up to him.

She struggled because in between those long graceful legs was a secret. One known only to the family.

She was a futa girl! Yes! A young girl with a male’s penis.

“You know it hurts when I run too fast, I get bad rashes… down there.” Said Tomiko.

“Aww, does it hurt that much? Here, let me help you,” he said, grabbing at her shorts.

“Eeeek!”

“C’mon sis, it’s not like you have anything to hide I haven’t seen before, just let me help you ok?” Daisuke said, grinning.

“… ok, but no funny business!” she replied, sticking her tongue out at him.

“Haha, you can be cute when you’re angry, here, why don’t you sit down while I check up on you.”

So Tomiko sat down on a log and allowed her brother to unzip her shorts. He slowly pulled them down and began to examine her thighs.

This wasn’t as uncommon a thing as you may think. Tomiko had recently hit puberty, where not only her breasts began to swell, but her penis began to grow as well. She wasn’t used to running with it, especially in the underwear she had.

“Stupid panties, they offer no support. It’s almost better to go naked.” Tomiko said, as her brother applied some cream to her inner thighs.

“I could let you borrow some of my boxers, they’re much more comfortable. And they let you hang a bit which offers a nice breeze down there,” said Daisuke.

“Eeww, no thanks, I think I’d rather just let you help me whenever I get sore…” Tomiko said, blushing ever so slightly.

“Oho! Then I bet you’d like it if I did this!” he said, grabbing her cock at the base while he grabbed at her sac.

“Ahh! Don’t do that” Tomiko screamed, as she flushed even redder. “You know mom said we shouldn’t be doing this.”

“I know, but she’s not here, and you know you like it. What’s a little fooling around between brother and sister huh?” said Daisuke.

“… well, it does feel better now. Maybe we can fool around a bit more” said Tomiko, biting her lip.

“All right! Time for the fun to begin!” said Daisuke, as he jumped on top of her.

“Oof, not so hard!” Tomiko said, falling off the log and into the sand, with her brother on top of her. “Don’t go so fast!”

Daisuke ran one hand up her shirt to fondle her breasts as the other slowly worked its way up and down her cock. A little white globule of pre-cum slowly worked its way down her head and began to lubricate her cock. He lifted up her shirt and began playing with her sensitive nipples.

"Your breasts are so sensitive Tomiko, no
