They were your secret petgirls...

"Remember how we used to do petplay? It was how you lost your virginity Olivia, remember? You were my doggirl and you." Pointing to Kayla. "were my ponygirl."

You see that blank look fall over their eyes, then they both blush fiercly. "John! Don´t say it out loud. We´d die of shame if someone found out."
You just smile and give them a naughty smile. "Remember how we promised to get back at it?"
This time Kayla speaks up. "But that was so long ago. We´ll have to be re-trained." You make a wave in the air. "Hello? We´re young, we have plenty of time for that! Now, come with me and I´ll help you achieve your dream to be my full-time petgirls."

The twins follow you over to Erica´s mustang and get in. Instead of driving home you stop next to a big sex and leather shop that you´ve heard about. When you get in you´re immediately greeted by a middle aged man who works there. He shows you to some lovely gear to use on the twins.

Olivia gets a near full-body padded leather suit which fold up her limbs to **** her down on four limbs. Its open in the back for "fondling" and her breasts will poke out. You buy a tail with several attachable buttplugs. This leaves her head. For that you get a muzzle which looks like a dog nose. Hidden within is a ring gag or ballgag. The muzzle is head in place via several straps. To finish you buy her a hood with short leather dog ears attached.

Kayla gets a set of hooves though you intend her to walk bipedaly. You also get her a harness of leather straps to show of her breasts and waist. To change things up, you also get her a pair of sleeves so that she can walk on all fours like Olivia along with a saddle for you to sit on. To round things of you get her three different head harnesses, all with a bridle gag ofcourse. One can have the bridle adjusted by the reins in the back. One bridle is much thicker and a bit softer and is meant to just shut her up. The last one has a built in blindfold.

As you leave and the cashier is getting ready to process your purchase you simply tell him. "Name´s John Doe. I don´t need to pay for this." He nods and lets you go, no protest.

Now you all get back in the Mustang and drive off to your home. All of you excited for what´s to come...
