"You're late."
I stood in front of the third floor luxury apartment suite. A freckled woman almost half a head shorter than me stood in the doorway, a cross expression on her face. Her long, red hair lay in bouncy curls on her shoulders and back, and seemed to quiver in disapproval at my sight. Despite her diminutive appearance, she was the same age as myself.
"I'm very sorry, Mistress Alexis." I didn't bother to tell her that the bus had to take a detour, which cost us 15 minutes. I knew it probably didn't matter. Instead, I simply bowed my head in obeisance.
Her lip curled slightly. "Very well... You'll be punished for this later." She stepped aside to let me in, and released me from my harness after closing the door behind me.
"Dinner's already been served. You can go get changed; you don't have to attend me today."
"Yes, Mistress." I bowed to her.
An female voice sounded from the kitchen. "Is that Milly?"
"Yes, mother!"
"Well, don't forget to let her eat dinner when you're done."
Mistress Alexis jutted her head toward the stairs, and I wasted no time heading up. I didn't have a room of my own - rather, I was headed to Mistress Alexis' room. It was decorated in a girlish style, with pastel tones for the walls and drapes. Her four-poster bed took up a third of the room, while a rolled-up padding lay next to it - my own bed, though I didn't usually sleep in it.
Only one drawer mattered to me, and that was the one that contained "my" clothes. I wasn't allowed to own any sort of property of my own - a slave's owner could delegate certain objects as "possessions", but with a word those could be taken back. The clothes I wore were all the property of my Mistress (or maybe legally speaking, her parents?).
I quickly got dressed in my casual outfit. Many slaves were allowed to pick their own outfits, so long as their collars were still visible. Sometimes the slaves were also required to expose their breeder's tattoo. Mistress Alexis took a much more heavy-handed approach, dictating my entire wardrobe, as she enjoyed dressing me up - and usually taking plenty of time to play with my amply-sized breasts while doing so - ample compared to hers, especially.
The meat and potatoes of that wardrobe was the maid outfit. Mistress Alexis absolutely loved maid outfits, and had made it clear that I was to be wearing one whenever possible. It has a shortened skirt to match that of my school uniform - and, in fact, the entirety of the rest of my wardrobe. The thighs of a true-bred ponygirl are always well-developed, and no owner of mine would by able to resist displaying them.
Having changed, I started tidying up. The room was not messy in the first place and it only took a minute to get everything back into place. Having finished my duties, I took a spot in front of the door and knelt on the ground, resting my hands loosely in my lap - a relaxed position in which to await my Mistress.
Despite how she'd greeted me at the door, I knew Mistress Alexis was not particularly upset at me. She was well aware of the importance of my ponygirl training, and while I was late for dinner, this was well within expectations. Rather, it was likely that she was simply looking for a casus belli to be particularly aggressive while playing with me later. I was already accustomed to her quirks - she was a fairly predictable mistress.
My training wasn't her call to make, after all. Mistress Alexis wasn't actually my owner. Rather, Alexis' father - Mr. Logan Wilson - had been leasing me from my owner for the past four years as a personal servant for his daughter. Part of the lease agreement required that I be permitted to attend my ponygirl training.
Over the past few years, I'd become quite close to the Wilson family. Logan, his wife Augustine, their son Henry. Their slave, Sally. And of course, there was Alexis herself. Master Logan and Mistress Augustine had always been warm towards me, and I really couldn't have asked for much better masters. They'd even offered to buy me from my owner and allow me to remain with Alexis. I respectfully declined that offer, as I had other plans.
It was only a few minutes before Alexis arrived. She looked down at me with her trademark imperious attitude, meager chest thrust forward and chin up.
"Hmph."
She turned and header over to the drawer. Out of the corner of my eye, I watched her pull open "that drawer". Well, I had known to expect this anyway. What came out was her strapon harness, fitted with her favorite dildo, for use on me. It was covered with ridges and bumps, and its base was designed to fit in a strapon and stimulate the wearer's clitoris. Or so I'd heard - I had never worn it.
"Strip, and get on the bed."
"Yes, Mistress."
Well, so much for getting dressed. I neatly rose, peeled off the outfit, and made my way over to the bed. This sort of play was part and parcel of our relationship. I sat on the edge of the bed, and once she'd put on her harness, she came to sit right beside me, wearing nothing else. The dildo jutted from between her legs.
Her hand crossed over and grabbed my far breast, while her lips closed around the nipple nearest to her. My eyes closed as she sucked on it, massaging me at the same time. Her hands cradled my breasts, playing with them like putty in her hands.
I leaned back onto the bed as Alexis bore me down. She pushed me forward so my knees were on the bed, then pulled my legs apart. Her face came down between my thighs, lapping at my sex. I squirmed from the stimulation. While exercise would normally ward off arousal, working as a ponygirl tended to build it up, as the harness was designed such that that crotch strap only very slightly stimulated the wearer. As the ponygirl's arms were kept constantly restrained, she'd be unable to relieve herself through masturbation. In my case, I'd also had the experience with Jack while being bathed - I had only gotten him off with my mouth, and had run away before we could get any further.
I hadn't realized how close to the edge I already was.
Mistress paused. Her eyes looked up at me, narrowed.
"You... you had some fun without me today, didn't you?"
A jolt went down my spine.
