Riki was your enemy, and you had accepted that he would always find a way to pick on you at school.

But one day, you decided it was time to get back at him.

As you walked into school, you spotted him chatting with his friends, his back turned to you.

You sauntered over and, with a playful flick of your freshly manicured nails, scratched his spine.

You expected him to cry out in pain, but instead, he turned around, his face flushed and a surprised moan escaping his lips.
