Yes, Zoe was sure she heard her nan address the girl as "slave" her mind imploded. The young attractive girl was her nans slave??? How, what the fuck is going on. Before Zoe could take in what was happening her nan had lifted her two feet off the floor her fat cellulite legs and thighs clasping the young lady's firm body then she spoke but it was not the voice Zoe knew, "move slave forward" as she slapped the girl's ass with the strap. Ciara let out a surprised yelp and began to move very slowly forward.
Zoe watched as the young girl started to move down the room with her granny sitting firmly on her back and two straps in her hands. To all intense and purpose the girl was her grandmothers pony, her slave.
This was Ciara's first time to carry Agnes the woman was heavy and she laboured under her. It was hard to breathe through the knickers on her head and her mouth was full of the taste of the woman's pee & crotch. The full length mirror at the end of the room confirmed Ciara's role, she was 23, fit strong and healthy, successful in business and not short of dates from both guys n girls, she ran a business with 35 people reporting to her.
Now she was on all fours carrying a fat old woman a stranger who she met on line on her naked back. She could feel the heat from the woman's buttocks and the pubic hair from her pussy rubbing her back. Agnes her rider now had her full weight on Ciara's back as she struggled to continue to carry her. She moved forward, and sign of slacking and Agnes used her strap, hard enough to let Ciara know who was in charge but not to leave lasting marks, this was part of the limits agreed.
Ciara was struggling to breath but she was now a slave to Agnes for this ride. Sweat was forming in her hair and was starting to seep down onto her forehead and face, this added to the smell and taste of the urine soaked knickers that enclosed her head and face. Every breath she took carried the smell of the urine her nose and mouth were full of pee and the taste hit the back of her throat. She moved with slow deliberate movements but every now and then the strap Agnes held would descend on to her slim ass cheeks causing sharp pain and shock that ensured her rider was enjoying her ride in comfort.
The straps around Ciara head were very effective, they held the ball gag quite firm and the air holes in the gag allowed the air to carry the taste of the urine and sweat from the knickers into Ciara's mouth and nose. A strap ran under her chine and closed on the top of her head with links on either side for the reins, which Agnes had attached. The panties, gag and straps ensure Agnes had total control over the movements Ciara made and restricted the air supply.
