Petgirl

Luna found her collar and dogtail butt plug.

She stripped quickly and put her collar on.

When she was on her knees her Mistress took the plug. She patted her head and down her back before pushing the plug in.

Luna didn't flench, she had grown use to the tail and sometimes found herself missing it.

Harry and Hermione moved in front of her and smiled down at her.

She gave her owners a happy bark and panted like the dog she was.

"Such a good girl. Aren't you?"

Harry said as he rubbed her head.

Luna barked again and licked his hand.

It might seem strange but to Luna this was perfect. She had two great owners that took such great care of her. She never had to think just be a good dog.

And the sex was mind blowing.

She already had a fantasy of living with them after school. Naked all the time, on her hands and knees, sleeping at the foot of their bed..

"I love our puppy Harry." Hermione smiled as she kissed him.

Luna panted and watched them snog. Her owners were so sexy. She loved watching them snog but seeing them fuck was second only to being fucked by them.

Harry broke the kiss and looked at Luna. "Well what are we going to do with our pet,love?" He asked Hermione.

"I got some ideas." She smirked and looked at the blonde.

Luna barked eagerly.
