"I'm so sorry, Mistress…you're just so sexy…" Vi looked at my wife and then me.

"Look at your face, Vi…you're already lost. And I don't think it's fair to Wendy or me that you're going to come as soon as either of us touches you. Lay on the bed and take care of it. Now."

Brenda's words had an effect on me. The harshness of it, the coldness of the tone and the complete dismissal of Vi as an equal. My wife's voice was like a whip, lashing Vi with every sentence. I'd had more experience in withstanding the delicious harshness of my wife's commands, but I knew Vi was falling apart at them.

"Mistress Brenda, may I unzip my shorts to allow myself to masturbate, please?" Vi said, sitting on the bed.

Brenda narrowed her eyes at her, scowling. "How the fuck else are you supposed to be able to touch that little cunt of yours, Vi? Don't make me come over there and do it."

Vi looked at me with a pleading smirk, as if she were thinking the idea of Brenda ripping her shorts off and licking her was better than just masturbating herself.

"And don't look to Wendy to come save you, slut, she has other things to think about. Like how she's been silent this whole time and thinks I haven't notice her standing over there shifting around. Her pussy is probably wetter than yours is." Brenda looked over at me, and my heart jumped.

"Mistress Brenda, I'm a good girl. I've been listening to you this whole time, learning how I can be a smarter slut than Vi, and I've not allowed my pussy to get wet." I said, obviously lying. I wondered which path Brenda would take: going along with my fib to give us time to watch Vi, or punishing me for being a liar. Either outcome was delectable.

"Good. You're learning, Wendy. It must feel good to not be the most wayward slut in the room any more. Congratulations." Brenda said. She slapped my ass just as hard as she’d slapped Vi’s, and I had to suppress a smile at the delicious pain.

"Mistress Brenda, I'm going to masturbate now." Vi said. "May I also unzip the bra cups to let my nipples free?"

"No. Why on earth would you think that you'd be allowed to do that?" Brenda said.

Vi opened her mouth.

"Just get yourself off, slut, stop thinking about all these fucking questions that I am getting tired of answering. I can tell you're thinking of ways to delay yourself. Work those fingers into your little soaking slit so we can move on with the day.”

I walked next to Brenda, who was standing with front-row seats to Vi's masturbation. She pulled the zipper down carefully, exposing herself to us, the flesh underneath the latex basically matching it in redness and slickness.
