"I guess it's good that you'll have Brenda and I to both wear out, since I think that's the only way the two of us are going to be able to keep up with you.” I smirked. "You're going to be our little sex machine, aren't you, Vi?"

"God yes, Mistress…”

I felt myself heat up with her words. I stood behind Vi and pulled her hair back, exposing her neck. I kissed it, sucking it a little. "You know, my pussy might be a little too worn out for action, but…if yours isn't…and you're OK with not doing anything to me…" I put my hand on her stomach, my thumb resting below her belly button. "Do you want me to finger you, Vi, while we wait for Brenda?"

"Please…I'm still so horny…I know Brenda fucked me hard, but I want more…" Vi said, raising her arm above my head and drawing me closer.

I slid my hand into Vi’s robe and between her legs, feeling the slick, hairless pussy lips under her panties. She was already wet again, and I loved the feeling of my fingertips between her slick folds.

Vi gasped as my fingers made contact. "Fuck…"

"So wet again…” I said, whispering in her ear.

"Yes, Wendy…oh…please…don't stop."

I slid my finger into Vi, curling it back up against the sensitive skin inside of her pussy. She smiled and raised her eyebrows at the sensation. I used my other hand to grab her left breast, pushing it upward.

"You are so wet, Vi. Brenda is going to love how wet you get. She's going to teach you how to squirt like I do, would you like that?" I whispered.

"Fuck yes I would…" Vi gasped, the pleasure beginning to take over her body. I knew she wasn't going to be able to speak for long now.

"Good girl." I said, adding another finger inside Vi as she gasped. "I can probably put three in here with how relaxed that dildo made your pussy…"

"Please…" Vi rolled her hips against mine, riding my fingers. “Mistress…”

"Yes, Vi?"

"Please let me come…I need to…"

“Already? Go ahead and come. Come for Brenda and me.”

Vi shook, a shuddering orgasm taking her over. A smile spread across her face as she nuzzled up to me, enjoying at least her fourth orgasm of the day. “I’m never going to stop loving you doing that to me.”

I smiled, my face buried in the nape of her neck as she came back down to reality. I slid my fingers out of her as we held each other close, our breathing getting back to normal. I wanted so badly to make her drop to her knees and eat me out, but I knew I couldn’t take it.

“Does my perfect little sub want to clean up the mess she made on my fingers?” I said.
