"Please fuck my ass, Master."

"Please fuck my ass, Master," Mrs. Tan says softly.
"Louder, slut. In fact, why don't you tell your former-Mistress personally about what you want me to do- NOW!"
"I want my Master to fuck my ass, Tea! I want him to fuck the tight ass that I've only ever shared with you!"
"That's better. Speaking of asses, are you ready to make our other bitch work, ****?"
"Yes, Master. I want her to lube up my ass...so that you can fuck it."
"It would be my pleasure," you say with a smile, "One ass a time though."

Tiffany giggles and walks over to Mrs. Ling. She leans in close and talks dirty in her ear. You can't hear what she says, but the bound Head of Security nods in agreement to whatever it was.

You turn your attention back to Mrs. Tan's ass as Tiffany gives you a thumbs up. You pull out of her pussy and rub your cock against her asshole. This serves to both moisten her hole and to tease her. She seems to want it and you aren't truly in charge if you give your slaves what they want all of the time.

After a minute of this, you decide to finally stick it in her ass. You get about 1/4 inside her in one thrust, eliciting some light grunting. You spit on your dick and push it in further. No reason to hold back- this slut wants it!

Meanwhile, Tiffany is moaning lightly as Mrs. Ling tongues her asshole. If she was hesitant about doing this, it doesn't show. What did Tiffany say to her?

You finally manage to push your whole cock in the Teacher's ass. She's only shared this with her Mistress, which means that she's never had a real cock in there.

"How's your first cock in your ass, ****," you ask.
"I love it, Master," Mrs. Tan replies, "Thank you, Master."
"You've been trained well, slut. Who's a better ass-fucker: me or your Mistress?"
"You are, Master! I'm sorry, Tea, but he's just so damn good!"
"It's alright, ****. She already knows that," you say with a chuckle, recalling her earlier DP from you and Tiffany, "If you're good, we may give you a double-fucking as well later."
"Thank you, Master! I'd like that, Master."

Pleased by her attitude, you fuck her harder and even reach down to rub her pussy. The added stimulation is getting to be too much for her. One more orgasm and she truly belongs to you. That also means that you get Tiffany's ass for the first time too.

"Permission to cum, Master," Mrs. Tan practically shouts.
"Hmm...what do you think, Tiffany?"
"Fuck yeah, Master. Make this bitch cum on your big, hard dick!"
"Permission granted then, ****. Cum for us!"
"FuuUUck- I'm cumming again for my MaSTER!"

The woman bucks against her bondage and you **** another orgasm to shoot through her body. She writhes and writhes, which only serves to make your cock rub against the inside of her ass even more. If she keeps this up, she will make herself cum again.

You focus your thoughts on every single other thing you can think of besides this woman's ass squeezing your dick. You want to make yourself last to fuck Tiffany. You want to give her the honor of making you cum inside of her.

She finishes her orgasm and just grinds her ass against you. She's definitely yours now.

"That was fun," you say, "Now then- you expressed interest in both fucking this slut here and getting ass-fucked by me, Tiffany. Which one do you want?"
