They get properly "dressed"

After you get home you hurry in with the twins while they giggle between each other about what you´re gonna make them do. Once inside, you bring them to the living room where they fumble with closing the blinds. While they do that, you unpack their new outfits and place them on the floor.

Once the blinds are closed the twins come over to you sitting on the couch. Olivia sits down on her kneels while Kayla sits down next to you. You push her down on the floor. "Remember, pets don´t sit in human furniture, and you are my PET-girls, remember?" Olivia and Kayla nods as Kayla sits down on her knees next to her sister. "Now, to get started you have to undress. Animals like you don´t need human clothes afterall."

They shiver, but then hurriedly undress, standing naked before you in less than a minute. Their toned identical bodies look great nude, but they´ll look even better once they´ve assumed their "true" role. "Kayla, we´ll start with you. Olivia, fetch me the bridle like a good dog while I get her into the harness."

Olivia crawls on all fours over to the bridles, but stops as she doesn´t know which one you want. While she´s deciding which one to pick up, you strap the harness on around Kayla's body. After you help Kayla step into her new hoof boots, Olivia crawls over, holding the thickest bridle in her mouth. You reach down and pluck it from her mouth. "Good girl." Olivia smiles and sits back on her haunches as you place the thick rubber bridle in Kayla's mouth and buckles the strap holding it in around her head.

After putting Kayla´s blonde hair up into a ponytail, you look over to Olivia. "Now then, are you ready to resume your training?" You say in a gentle tone as if addressing a dog or small child. To your surprise, Olivia answers with a high pitched bark. She´s really getting into her pet role. "Alright, fold your limbs up." Olivia obeys as you start putting her suit on.

After strapping her limbs in, you continue with the rest of her body, enjoying a nice grope of her breasts on the way. Once that´s done you pull the hood over her head and reach for the muzzle. "Now, since you haven´t been trained in a while you get the ball." You say as you attach the ballgag to the muzzle and present it to Olivia. She whines a bit but opens her mouth obediently. After buckling on the harness you pick up one of the buttplugs and attach her tail. "Stay here while I prep you tail."

You leave them for a moment to fetch some lube from your cupboard. Once you´re back you lube up the plug and then firmly shove it up her ass. She whines at first but once it in she wiggles her shapely ass, enjoying the sensation. Picking up another plug, this one a bit bigger you walk over to Kayla. "I´m sorry for forgetting to get you a tail. I´ll do that later." She gives you a sympathetic look but stays silent, bending over once she sees the buttplug. You´re less gentle this time, applying less lube and more raw pressure to get it in. Once you´re done you give her ass a smack. "There you go. Now you´re both ready to continue your training!"
