A few more useful tips, and some fun

"Hmm... Oh, I know! Whenever you have nothing to do and your boss is in the room, make sure to give him a sexy pose", Sonya tells Yu before giving her a quick example, using one of the kitchen chairs to do so.

She makes sure to show off her cleavage and ass in her position, even sliding her panties down a bit before giving you a quick wink and getting back up. She then headed back to Yu to continue her lesson, giving her a slap in the ass that causes Yu to yelp and blush.

"Ok, now, you must accept anything your boss does to you. He owns your body, and as such, he can do anything he wants when he wants. Whenever your boss gropes you or slaps you, you should act grateful and happy about it, and you should enjoy it", she tells Yu while motioning for you to come closer. You understand what she wants to do, and gladly do it.

You get closer and start to grope Sonya's breasts and slapping her ass which feels nice. She moans in response and grinds against your body, giving Yu a show on how to do it. Yu seems very interested, taking in every movement and moan. This goes on for about two minutes before you move away to let Sonya continue with her lesson.

Instead of talking to her, Sonya goes over to Yu and starts to grope her, feeling her up. Yu responds by acting just like she saw Sonya before as you were groping her, moaning and grinding against her, to which Sonya smirks before giving her a good slap.

"Good girl, that's the spirit. Whenever your boss invites someone over, you should act this way too, if they want to use your body", she compliments her as she continues to touch her body, and you nod at her, giving her clearance to use Yu.
