No, give her homework

“Heh, get dressed.” I started to clean myself up.

“Why?” she turned around and looked up at me from her back.

“Because puppy if you’re my bitch the first thing you need to learn is I’m the one in control. You could touch yourself now and try to finish yourself off but you know it won’t be as satisfying and if you do you should feel guilty for being disobedient. No. be a good dog and you’ll get to feel good. From now on I control that part of you. Your giving that part up to me and why are you doing that?”

“Because I’m your bitch.” she said and she stood up and started getting dressed.

“Good Girl.” When she was fully clothed I patted her head and kissed her forehead.

“Now let’s talk about homework.”

“What?”

“Well, one I expect you to keep your real grades up. My puppy should be a smart little doggy.

And two if you're going to find a new days like this for tutoring you’ll need to work hard to be a good doggy. So here’s your assignment, I want you to touch yourself the way I touch you. Do it before school end on the day of our next tutoring session and in the morning before school. Think of your owner when you do it.” She nodded and I gave her one last kiss my hand patting her on the ass. “Good dog.”
