How can she eat a sandwich when that guy is using her hair to jack off? Not that I don't like this picture or wouldn't do the same but I mean, come on. And are they at school? Sorry I just thought it was strange.

He wanted sex, she wanted lunch, and so they compromised on how to utilize their lunch break.

She doesn't look like she has much of an appetite anymore, to be quite honest.

Aika can't enjoy her sandwich because Kazuhisa is masturbating with her hair.
