Dick and Tongue

Yu comes back, clean and in her uniform.

"Yu," you say, "I'm going to pay Sonya the usual bonus for a teacher, and you will pay her the usual fee that a student would give a teacher in this situation."

"What is that?" asks Yu.

"What is that, sir!" says Sonya.

"Sorry, what is that, sir," says Yu.

"The usual bonus is a good fuck, and your fee is to lick her pussy clean afterwards. If you don't do it, you leave me no option but to fire you, and you will be on the street and at the mercy of those who want to harm you and your family."

"I'll do it!" says Yu, "I mean I'll do it, sir!"

"Good, you are a bisexual slut anyway, and the thought of watching me fuck Sonya and cleaning her up afterwards is making you horny as hell right now."

Yu blushed and looked down at her feet.

"Follow us on your hands and knees," you say. You lead Sonya by the hand with Yu trailing behind to a guest bedroom.

Without waiting for instruction, Sonya stripped and climbed on the bed. She got on her hands and knees facing away from you.

You strip naked and get behind her. You slide your cock into her and proceed to fuck her as she orgasms over and over again, a side-effect of your previous "training" to have her believe she orgasms at the drop of a hat when being fucked from behind.

"Oh god yes! Fuck me! Fuck me!" yells Sonya. You look over at Yu, who is entranced at the sight of you fucking Sonya. She holds the tip of her finger in her teeth.

You keep banging away at Sonya as she keeps calling out in ecstacy. You finally blow your load and pull out. You climb off of the bed. "Yu, suck my cock clean, then lick Sonya's pussy clean and keep going until you get her to orgasm."

"Yes, sir." You kneels before you and sucks you clean before climbing behind Sonya and licking her pussy which was dripping your your cum and Sonya's pussy juices.
