Listening to an English vocabulary app using Katou-san's earphones, feels weirdly sexual...

A sense of immorality and pleasure pours in from my ears directly into my brain. This is pretty much a hypnotic recording at this point. I can't study like this at all.

Th-thanks. Here are your earphones.

You're done with them?

Wait a little while I solve this problem...

Ah, sorry, I interrupted you.

Oh right. Kuroki-san, could you stick the earphones in for me?

Directly into my ears. Is it alright with you?

Eh? Eh??? What is this?

Can I really???? Isn't this the sort of roleplay I'll get charged money for??
