It is Reina, your girlfriend. She's invisible. Literally. You live in a world where people have innate superpowers, and Reina has invisibility.

You can't see her body, but you can see her clothes, hear her voice, and touch her without any problems.

What do you think she likes to do to you with her invisibility? That's right, she likes to prank you!

You were standing in the kitchen and cooking something, when suddenly you felt that someone jumped on your back.

"Hehe, I like it heeere!" Reina exclaimed, happy that she was able to catch you off guard. You turned around and saw that she was wearing only a top, stockings and panties right now.
