The rest of Sunday was relatively uneventful. Both of us were exhausted, so we just took a shower and spent the evening relaxing. Dinner passed much like lunch, I fed her bits from my plate until I was done and then gave her the scraps. Eventually I caught myself yawning and decided it was time to turn in early.
Marie liked to sleep in pajamas and on opposite sides of the bed, I did not care for either thing. Thus, when we went to bed, I pulled her to me, and arranged her in a manner I found pleasing, with her tits and pussy pressed up against me. As she lay her head against my chest I could feel the leather of her collar and I knew she was still wearing the buttplug. I didn't get much time to enjoy this cuddling though, as I almost immediately fell asleep.
At six in the morning, her alarm went off and jolted us both awake. I noticed she had rolled away from me in the night, but I had already decided not to worry about that. After I'm already asleep, I don't really care what she does. I lay in bed and watched her groggily stand and walk to the restroom. I could tell from her ginger movements and wincing that her body must be pretty sore, particularly her ass.
I too was a bit sore from the previous day's exertions, yet I still was sad to let her go. She has an office job she had to get to, while I work from home. Having her under my desk all day would have made the work go by a lot more pleasantly, but reality is what it is. After a short while I got up out of bed and went to join her in the restroom where she was brushing her teeth.
"So, obviously, the rule about you never putting clothes on in the apartment is suspended on weekday mornings when you need to get dressed for work and you may remove your collar and set it by the door when you leave. Also, any time you're going to leave the apartment while I am here, you are to check with me first. Understood?"
"Yes, Master," she said, around a mouthful of toothpaste.
"Good girl," I said, patting her butt before going back to lay in the bed a while longer. I enjoyed laying there and watching her get dressed. She picked a loose, soft dress, perhaps to avoid aggravating her various sore spots and bruises. Fortunately the only marks left behind were in places easily covered by most clothing. Soon enough she was done and she came to kneel at the side of the bed.
"Master, I finished getting ready. May I leave for work?"
I smiled, pleased with her obedience and sat up to face her.
"First, pet, stand up, turn around lift up your dress."
She did as I commanded and I pulled down her white panties before spreading her buttcheeks. As I suspected, the plug was missing.
"Tell me, slut, what is the rule I gave you about the buttplug?"
"Master... surely while I'm at work -"
I slapped her ass.
"I asked you a question, bitch, answer it."
"S-sorry Master. The rule is that I am to keep the plug in any time my ass is not being used."
"Right, and is your ass currently in use right now?"
"...No, Master."
"Which means you're breaking the rules. Go get the plug and the lube, and bring them here."
Shortly she returned and offered me the plug.
"No. You broke the rules, so you fix it. I want to watch you put it back in yourself."
She looked apprehensive for a moment, before her shoulders slumped in resignation. After a brief pause to consider her exact strategy, she got down on her hands and knees, butt towards me, and applied plenty of lubrication to the plug. It took some fumbling, as she wasn't used to putting things in her ass, but she got the tip in and started pushing in the plug ever so slowly.
"Come on now, you're going to be late if you don't pick up the pace."
"Master... it hurts!"
"Well, you should have thought of that before you took it out. If you don't hurry it up, I'm going to put it in for you."
That seemed to motivate her because she pushed the plug the rest of the way in immediately, flinching a little as the largest section passed through her asshole. As she turned around to pick up her underwear, I caught her chin in my palm.
"Now, of course you'll have to be punished for breaking the rules, but considering you have to get to work, I will forgo your punishment until you get home tonight. Isn't that kind of me?"
"Yes, Master. Thank you, Master," she said, reaching up to dab at her watery eyes.
