Tickling! (Patreon)

My OC: Natsuka, Sayaka and Momoe

They were enjoying at the pool.

Natsuka got giant suddenly.

Then, Sayaka and Momoe had a nice idea.

“Tickling!”

“I was getting bored of the usual water plays. Natsuka, you like being tickled, right? Right now, we are very small to you, but playing with us when we're tiny will give you a whole new sensation, don't you think?”
