Have them spank each other

“Since you two like getting in trouble together, you can co-operate for your spankings too” you say. “I’m going to watch you two spank each other. Dilly, you spank Debbie first”.

“B-but that’s not fair! I can get a spanking from Dilly Any time!”

“I’m Debbie!”

“I can get a spanking from you any time too!”

“Well you’re going to have to spank me first!” says Debbie, bending over.

“And don’t think I’m going to take it easy on you either!” Says Dilly, grabbing her sister’s swimsuit bottom, giving her a toe-lifting wedgie and eliciting an ‘Awp!’ from Debbie. Dilly lays into her sister’s bottom with a zeal, wide swings cracking loudly against her wet bottom.

“Oh! Hmph!” Debbie complains as her bottom begins to turn a healthy shade of red. She wriggles downward, grinding against the bikini bottom her sister is still pulling upwards. Dilly makes eye contact with you while wailing on her sister and grins. Her nipples poke against her swimsuit when she sees you watching with approval, and she lays into her task with renewed fervor. The ringing cracks of her hand on her sister’s bottom can no doubt be heard from one end of the neighborhood to the other.

Eventually, she tires. “I think… that’s about the best I can do” she says, shaking her sore spanking hand. “Are you sure you don’t want to have a go?”

“Not so fast you little minx! My turn!” says Debbie, straightening up and returning her swimsuit to some semblance of decency. “On your back minx!” she orders, and Dilly is lying on the ground so fast you could swear she fell. She meets your eyes and bites her lip as she raises her knees to her chest, clearly no stranger to the diaper position. Debbie settles in next to her, pinning her legs with one arm. She looks at you, her face breaking into an evil grin when she sees your encouraging nod.

If anything, the spanking Debbie gives is even more enthusiastic than the one she received. Unlike her twin, Dilly is a screamer, the loud cracks of Debbie’s palm on her taught tush being drowned out by her enthusiastic vocalizations. You enjoy the sight of Dilly getting her comeuppance at the hands of her twin sister.

But all good things must come to an end. Eventually, Debbie slows and stops, blowing on her sore spanking hand. “That was fun” says Dilly hoarsely, rubbing her sore heiney.

“We’ll have to do it again sometime”

“But first, we’ll need to cool off”.

“Pool?”

“Pool”.

The twins race each other up the steps to their pool and jump in, shrieking a little as the cold water touches their warmed skin.

“Thanks Reader!” says Dilly or Debbie

“Next time maybe you’ll wear out your own arm!” says Debbie or Dilly.

The twins wave goodebye to you as you continue on to your original destination.
