Make her work for it

[Look Elizabeth. If you really want that A, you'll need to work for it just like everyone else. You can start by masturbating and moaning my name.]

It wasn't much but it was the start of him taming her brattiness in order to make her more fun, that is more useful to him.

He didn't get a response right away for he checked the other text from Annie.

[Hey Loser. I see you are gooning again. How many times is it now? Oh, and since you didn't ask if you could goon, you aren't allowed to cum until class tomorrow.]

He smiled as he got an immediate response from the gooner.

[Nghhhh. 6]

He knew what it was but he just ignored it. He was going to check if there was any new messages fir anyone else when he heard a knock at the door. He went to see what it was.
