When Rin woke up from her nap, she decided to look out from Hanayo's knees. She could see the fence of the school's roof and the other girls warming up. It was a bit chilly, so Hanayo had kept her tights, aka Rin, on.
"It's a shame that Rin couldn't make it to practice today, but we can do fine with us eight today." Eli wished she knew why exactly Rin couldn't make it today; every time she tried to remember, it was like her brain slide over the reason. Oh well, a day's absence wouldn't be too bad.
With that, the girls got to practicing their new song and dance and Rin loved every moment. From how nice every shake of Hanayo's butt was when she jumped to the small pools of sweat that accumulated around her feet with every step she took, Rin got a whole new experience that she would keep in her mind forever.
But seeing and feeling was one thing; Rin wanted to see if she could actually touch Hanayo, give her a little tickle. With that goal in mind, Rin focused all of her attention on Hanayo's feet...
"Ah...!" Right as she was about to make a jump, Hanayo felt something weird touch her feet and force her to land on her butt.
"Hanayo-chan!" Honoka quickly rushed over to her along with the rest of Muse. "Is something wrong?"
"I don't--haha! D-don't know, it's--hehe! Something got in them and now--hahaha! It won't stop! Ahahahaha!" As horrified as she was by the situation, Hanayo couldn't stop laughing as it felt like her tights had come to life and were now tickling her feet.
In a certain sense, that was what exactly had happened, as the Rin tights giggle mentally at how fun it was to play with Hanayo's feet.
