"You'll learn through pain, Vi. It's the only way to make little sluts worthy of my time." Brenda turned the crop so the blows would land vertically, and hit Vi with a shot that trailed along her ass and down her thigh, a combination of impact and dragging that had made me come more than once.

"Oh god…Mistress Brenda, you're making me…fuck…wet. That feels so good…and it hurts…oh god…" Vi groaned, the chain I was still holding jiggling around.

"It seems like I can't do anything to you without it turning you on. Pathetic." Brenda said. She looked over at me, knowing that Vi couldn't see us, and smiled. This may have genuinely rivaled our wedding day for how utterly gleeful my wife was right now.

"Are you sorry for being such an eager little slut who can't help but be dripping wet while my wife and I hurt you?" Brenda asked, gently dragging the crop across Vi's ass and thighs, giving her a few moments of reprieve.

"Yes, yes…oh…yes, Mistress Brenda." Vi's hands were pawing at the sheets in anticipation of the next impact.

Brenda snapped the crop hard on Vi's upper ass, making her shriek, which turned to a moan that was music to our ears.

"Vi, you need to make that more of an apology, or we'll never move on to fucking you again. We will leave your pussy dripping and eager and go do something else with our night." Brenda said.

"No…no, please, I'm sorry." Vi whimpered. She pushed herself back up and into a proper submissive pose: head up, chest down, ass in the air. "I'm sorry for being an eager little slut who gets off on pain. Hit me on the pussy with that fucking crop, Brenda…Mistress Brenda."

Vi was ravenous at this point, and I could tell Brenda knew it was time to calm her down a little. Or at least stop relentlessly slapping her delicious thighs and ass for a little bit.

"Let me make sure I have the right spot…" Brenda walked toward Vi and put her hand on her pussy, stroking it, her thumb in the perfect position from this angle to press into her as much as possible with the latex barrier.

Vi started panting as Brenda played with her. This girl needed it so badly at this point, she couldn't even be still.

"There, got the right spot. Now I'll go ahead and let my submissive slut apologize properly after I slap her so hard she might learn to shut up for a few seconds." Brenda massaged Vi's pussy a little more before reeling her hand back with the crop.
