Mary crouched in her cage. She wasn't thinking about the funky smell of the black cloth bag over her head. She wasn't thinking about how if she wasn't let out soon she would have to empty her bladder leaving her kneeling in a puddle of her own piss. Like all good slaves she was thinking of the well-being of her master. She was in the cage because she had been "put away" as owners do when they are not using their slaves. She didn't enjoy being put away but she knew it reminded her that she had no real existence apart from her master. Her master, Gary, had been putting her away more often and for longer periods.
She was afraid that as he became older that he was losing his vigor and becoming depressed. She knew that it wasn't just because she was older. He was showing less interest in ass fucking their daughter Roberta and she was only twenty-eight. Her son, Jim, fucked Roberta more often and to tell the truth Jim fucked Mary more often lately. She hoped that Master Gary would be accepted for the clinical trials for vrilium, the new vigor drug. The drug companies like to test drugs like this in Briarton. If the subjects became sexually insatiable they had willing slaves to take care of their needs. The thought of Master Gary becoming sexually insatiable like he was when he was younger made Mary's clit twitch. She'd love to be fucked until she could walk like she used to.
She heard some movement. "You're taking Berta to the pet park," Master Gary's voice said. "Why don't you take the old bitch with you."
Mary perked up. She was the old bitch. It had been a while since she had been to the pet park. Pet play could be strenuous so younger slaves were usually used for it. Despite that it would be nice to get out of her cramped cage and into the fresh air where she could see the other slave pets and maybe have some fun herself. She heard the cage door open and someone pulled the bag off her head. Her son, Jim, was at the door. Her daughter, Roberta, was on all fours behind him. She was dressed in her puppy girl get up: leather leash attached to her collar, mitts, butt plug "tail", knee pads, slippers. She scampered away and came back carrying a tail for her mom in her mouth. Jim firmly inserted it into Mary's asshole. Roberta made several trips until Mary had all the gear she did. Jim got his mother set up for their outing. Roberta gave a happy little bark, talking wasn't generally allowed in pet gear. Mary could tell that Roberta was glad to have her join them.
"Wait," said Master Gary. "Don't forget the old bitch's mask."
Roberta didn't wear a mask or even dog makeup. She was young and pretty so it only took putting ribbons in her hair to turn her into a fantasy show puppy. Mary was an old bitch so maybe it was best if her face was covered. Jim went to the gear box and dug out her old PVC basset hound mask. It covered her face completely except for her eyes and mouth and fit snugly around her neck. She glanced at herself in the full length mirror in the other room. If she didn't look like an old bitch before she certainly looked like one now with her floppy ears and sad, droopy expression.
Jim picked up their leashes and they walked to the front door, Jim upright and the two slave pets crawling in tandem ahead of them. While they made their way down the front walk Mary sidled onto the lawn, squatted and peed. Their next door neighbor paused from trimming the hedges to watch her relieve herself. While they were walking to the playpark that contained the pet park they met a woman they didn't know.
She smiled brightly. "Your dogs are so cute! Are they friendly? Can I pet them?"
Jim said, "They're very friendly. Feel free to pet them."
Starting with Robeta and then Mary she began to pat and rub them all over their bodies. It was quick but Mary was sure the woman stuck at least two of her fingers in Mary's cunt. Mary and Roberta swayed their asses from side to side to get their tails going to show they enjoyed the attention. The woman continued on her way. Mary hoped she enjoyed sniffing their cunt smell from her fingers.
