Sonia started looking around the house for objects to place auras on, bearing in mind the affinity between their purpose and the function she wanted them to perform. That she wanted Maya's power to be limited didn't mean she wanted to waste it. She went room by room, looking at everything, trying to see if any ideas came up, and occasionally snickering and giggling as she imagined the uses she could put some of those things to, assuming Maya could make it happen.
It took Sonia at least half an hour to look at every bit of clutter in her house with the new eyes of someone thinking up magical uses. In the meantime, Maya had finished the washing up, and was wondering what to do. She decided she'd better tell her friend, if they were still friends, that her task was done.
"Sonia?"
Sonia slapped her, and Maya yelled.
"Miss," Sonia said. "Don't make me remind you again."
"I'm sorry, Miss. I just... wanted to let you know I was done with the dishes."
"Good. Get on all fours."
"Why?"
Sonia grabbed her by the hair, pulling hard on it, making Maya scream.
"First, I just reminded you to call me Miss; and second, when I give you an order, you obey it, immediately. You don't ask questions, you disrespectful little shit."
Maya was about to say something, but then she just looked sad, nodded, and got on all fours, as ordered.
Sonia sat on Maya's back, placing her slippered feet on either side of her face.
"That's why," she said. "Take me to my room, pony."
Maya sighed, but crawled to Sonia's room, bearing her weight on her back. Now and then, Sonia played with her by pressing her feet against her face, or bending her ears.
"Good girl. Now here are the things I want auras on." She pointed at a bunch of scattered objects on the floor. "We'll start with the most important."
Sonia stood up from Maya's back, who sighed with relief, and picked up a collar she waved in front of her face.
"I want to be sure I can control you," she said. "Set this up so I can turn your magic on and off. Oh, and so I can give you pain, too, and obviously, make it impossible to remove other than by me."
"Uh, Sonia?" Maya said, correcting herself as soon as she saw Sonia's face. "Er, I mean, Miss! Is that, um, is that really necessary?"
Sonia glared at her and Maya bowed her head, reaching for the collar with one hand. She placed it close to her eyes, and focused on it for a few seconds.
"It's done, Miss. You can cut off the flow of magic for whoever's wearing this, and cause them... er, pain." She shuddered. "You need to touch the collar with intent, and it will happen. You can release it the same way, too."
"Well, let's give it a try, then. Put it on."
Maya begged Sonia with her eyes, but all she saw was her determination. She put the collar on, and as it snapped closed, she felt she was locking herself into a horrible fate. She couldn't help it, though. If she tried to refuse, Sonia would just make her do it by force, and whatever else, she knew she wouldn't be able to physically fight her. She loved her too much for that, and was completely incapable of harming her in any way.
Sonia laid a finger on the collar, and Maya felt the sense of power that worked through her mind dissipate. It was working. then she screamed as she felt pain pervade her entire body. It was only for a second, but it was such a complete, overwhelming experience, it made her lose her balance and fall on her belly, from her previous position on all fours. She shivered on the floor, and it took her a few moments to come back to her senses, enough to be able to interpret the sounds she heard as Sonia's laughter.
"Very nice," Sonia said. "I see you didn't hold out on me."
"I wouldn't do that, Miss." Her voice trembled from her previous exposure to pain and the fear that Sonia would use it again.
She flinched as she saw Sonia crouch down by her and lay her finger on the collar again, but it was only to restore her power. Sonia even stroked her hair.
"There, there. You know if you're going to be the great help I require, you need to be trained. I won't use this more than is necessary, unless I get bored."
Maya kissed Sonia's hand. She really was grateful to Sonia for that, but couldn't avoid realising how pathetic it was. Not that there was anything she could do about it.
Sonia noticed Maya was close to her breaking point. She didn't know the collar would give her that extreme pain. If it was linked to intent, it may not have been a good idea to imagine her whole body writhing and hurting, but she wanted to make sure her thoughts were clear enough. She had no intention of apologising to Maya, but she admitted to herself that she hadn't deserved it. She hugged the girl, and took her to bed.
"It's been a long day, sweetie," she said. "We can continue tomorrow. Now, be a dear and lie across at my feet so I can lay them on you."
Maya complied, remembering the last night they had slept together as friends. Even then, they hadn't really been equals, and Sonia had made her smell and kiss her feet. She felt a strange desire to do it again, as if it were her place. After all, Sonia had shown she belonged to her. She dithered for a few moments, but then she decided it was best to keep Sonia happy, especially now she could hurt her so much.
Squirming under Sonia's bare, fragrant feet, Maya pressed her face against her soles. First, she sniffed them. Their cheesy, acrid smell penetrated her nose, and though she was disgusted by it, she was beginning to get used to it too. There was something comforting and familiar about having her owner's feet planted on her face as she let their stink take her over.
"Your feet smell like roses, Miss," she said, as respectfully as she could.
"Of course they do, little puppy," Sonia said, chuckling.
Maya kissed Sonia's feet, hoping that would be all.
"Good night, Miss. Sweet dreams."
"No, that won't do. I want nice puppy licks until I fall asleep."
Maya, who was finding the sharp smell of Sonia's feet overwhelming, didn't even want to think about tasting them. She had licked them before, but doing so in complete darkness, under the sheets, with nothing to focus on but the stink assaulting her nose and the sticky, clammy texture on her face, was much worse.
She gave them one last kiss, postponing the inevitable. But then she opened her mouth, pressed her lips on the sweaty soles, and began to lap at them like a dog, giving them slow, soft strokes with her tongue, as she inwardly winced at the flavour.
Sonia wondered if she would have to punish Maya again, or if she would obey. It didn't matter to her. Maya would become her devoted slave, the hard or the easy way. Both would be enjoyable and fun for her, and whether Maya liked it or not was immaterial. She sighed with pleasure as she felt her slave's tongue lapping at her soles, knowing how dirty they were, and closed her eyes.
She was certain that things would only get better. For her, anyway.
