It was dark for a few minutes and Riko found that she couldn't move at all no matter how hard she tried. Eventually, she got some light when the space she was in opened up and a giant head looked down at her.
"Let's see... hmm, I'll go with these today~"
"Is that... Ruby? But how am I in her room? And why is she so big?" Before she could try to ask, Ruby picked her up and began placing her between her legs. Ruby pulled Riko tight against her vagina and butt, and it was only then that Riko realized what she was - a pair of cute, pink panties that were now covering Ruby Kurosawa.
If Riko had a face, she would be bright red right now instead of the pink of Ruby's panties.
"How did this even happen? How do I turn back to normal? How badly is Dia gonna murder me when she finds out about this!?"
Riko couldn't see anything besides what was below her, so she noticed when the ground changed from asphalt road to the tiles of the school's entrance. She watched Ruby change her shoes and walk towards her class, still carefree and unknowing about who exactly was her panties.
