Brenda held the riding crop out for me and I took it, bowing slightly to accept my wife's gift.

In our discussions, as we got deeper into our relationship, Vi told us that she especially loved spanking and impact play. Light bruises or welts from her pelvis down to her knees were OK and could be covered with clothes, so she asked us to have fun.

And I was about to.

I drew the riding crop back and snapped it against Vi's ass, the sound of the impact delicious and sharp. I saw Vi's hamstrings tighten as she reacted to the impact. I swung the crop again squarely on the back of her thigh, the welt forming instantly.

"Fuck, yes…" Vi growled.

"Wendy, your sub is enjoying this…again. Do I need to teach you how to give her genuine pain so she doesn't sit there moaning while you pat her gently with that riding crop?"

Vi whimpered.

"Please…please make her hurt. She can handle it, she has so much to give…"

Brenda grinned, the way a lion looks at a zebra as it is cornered by the pride. Brenda's whipping technique was a bit legendary, and put mine to shame. Some of the other women we played with said that a whipping from my wife ruined getting it from any other woman. Maybe they were being a little hyperbolic…but not entirely.

"Wendy, you have to hit sluts hard and in the right spots." Brenda gave Vi a warning tap on the inside edge of her left asscheek, causing her to shake visibly. "If you're going to beat your little fucktoy, you have to make sure that she's really, really sorry. Do you think that little taps on her ass and thighs will give that to her?"

"No, Mistress Brenda. I don't."

"Right. You have to use this tool like you mean it." Brenda smacked Vi hard, really hard, on the other side of her ass, right below the hemline of the shorts.

"Fuck!!!!" Vi yelped, pushing herself forward, almost laying flat in reaction to the impact. I let the chain go lax and tilted my head to see that Vi was smiling. Oh, she had a hell of a tolerance for this…Brenda was going to love it compared to my sensitive ass and thighs.

"Vi, keep your back arched and keep your thighs available to me. Don't think you can hide from this." Brenda said, walking around her, picking her next spot to hit.

Vi complied, pushing her ass up in the air as if she were getting fucked doggy style from behind. It was a little hard not to drool a bit, seeing this beautiful woman so available for our taking, her ass ready and available for anything we wanted.
