Yes, but on one condition...

"Not yet," you reply, "There's something you have to do first."

"What is it, master," Donna asks submissively, "I'll do whatever you ask."

"Really beg me. I mean, lay it on as thick as you can."

Donna nods and thinks for a moment, at least as much as she can with the two young women still working on her.

"Please let me cum, master! I really, really need to! I haven't had a girl make me cum in a week! Ms. Tan has been holding out on me and I'm horny as hell! Please- I'm begging you!"

"I'll consider it. Your turn, Jenni," you say.

She looks up at you, a little confused.

"It's simple, honey. If Donna wants to be allowed to cum, you have to beg as well. Got it?"

Jenni and Donna share a look, the former looking into the latter's sad eyes.

"Please let me make Donna cum," the busty blond begs, "I haven't ever pleasured a girl without making her cum and I don't want to start! Kristi and I will give you the same pleasure we're giving her if you let us!"

"Is that true," you ask, turning towards Kristi.

With the gag around her lips and her wet panties in her mouth, she can't talk. In lieu of that, she nods her head vehemently.

"Alright, you can cum when I finish counting to five. Okay?"

Donna nods, as Kristi and Jenni resume their work on the young woman. Kristi fingers her hard and fast, while Jenni suckles on Donna's right breast like a happy newborn.

"Five," you say starting the countdown, pausing a few seconds until you say, "Four."

The wait is even longer this time and you place your hand on Donna's stomach, slowly running down towards her pussy.

"Three."

As you begin to rub the top of her pussy, you look and see pure lust in Kristi's eyes. She's into this!

"Two," you say, beginning to rub it faster and harder.

Donna is visibly shaking and practically bucking against the bed now. She really wants this.

"One. You can cum when I say 'zero,' ****."

You reach a bit further down Donna's pussy and find her clit. You squeeze it tightly.

"Zero. Cum for me, ****!"

The shy and submissive brunette suddenly cums like a crazed whore! All of the **** and waiting has driven her to a massive orgasm. She begins to scream, leaving you with one choice.

You abandon her clit and lean in to kiss her. She accepts this and actually kisses you back. You have a new helper, you think, and she's willing instead of doing it under duress.

After a couple moments, the show ends and everyone calms down. Jenni and Kristi resume their old positions, while Donna catches her breath.

"Good job, my twin slaves. I think Kristi here has earned a reward," you say.

You kneel down on the floor and reach behind her head. She leans forward, allowing you to untie the cloth gag properly. You pull it off and remove the panties from inside of her mouth as well.

However, what Kristi does next is very surprising...
