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.
"Good girl. Now, go ahead and go to work. And make sure you take the lube with you, in case you need to put the plug back in while you're out."
"Yes, Master. See you tonight, Master."
With that I laid back down and ignored her while she got herself back in order and then left.
Without my new toy, the rest of the day passed like most others. Except for the distinct soreness in my cock I could almost believe the previous weekend hadn't happened at all. I didn't have much work to do that day, so I spent the free time shopping for some new toys. I ordered some cute dog bowls to feed her with, some more containers of lube and a few other surprises. I have to admit, I perhaps got a bit carried away. Having a woman who has agreed to let you do whatever you want makes shopping for sex toys a lot more exciting. Around eleven thirty I realized her lunch break would be coming up soon, and I decided to check in on her, so I sent her a text.
You haven't broken any rules, have you pet?
She responded quickly.
No, Master.
Good. When you're on lunch break, go to the restroom and send me a picture of your asshole with the plug in.
She did not respond, but around forty minutes later I received a clear, if oddly angled, shot of her ass with the bright blue plug clearly visible, snugly nestled in her asshole. I haven't received many naughty pictures in my life and I quite enjoyed this one. I mentally added 'take embarrassing nude photos' to the growing list of things I wanted to do to her. I spent the rest of the day generally fucking around and fantasizing about what I would do when she got home. Unsurprisingly I got pretty worked up and decided to partake in some pornography and masturbation. At the time I figured it would be just a warm up before the main event, I wasn't planning on an orgasm, but of course I ended up getting pretty into it. Right around the time I was feeling about ready to come, I heard the sound of keys turning in the door. A moment of juvenile fear rushed through me as I realized someone was about to walk in on me with my dick in my hand and porn on my screen, before I remembered that I am an adult and this is my apartment.
"Hello, Master," Marie said cheerily as she shut the door.
"Welcome home, pet. Get changed and then come kneel over here," I replied over my shoulder. She seemed to pause for a moment, taking note of what I was doing, before complying. Shortly afterward she was again kneeling before me, naked except for her collar. Her mouth opened slightly, predicting my intention, but I had a different idea. I just kept right on stroking and when the moment arrived I sprayed my load over her face and hair. Only when my orgasm was complete did I pull her head forward and place my cock in her mouth. Without being ordered, she began softly sucking the dregs of semen out of me and swallowing my piss.
"Ahhh, that's a good girl. How was work today, slut?"
"It was good, Master. I -"
I admit I was barely listening to what she was saying, as I was busy enjoying the sight of her talking casually while covered in my semen. Still, I got the jist of it enough to ask her a few questions. I noticed that whenever she was not talking, she would automatically go back to sucking my cock or licking my balls. Perhaps she was trying to put me in a good mood so I'd go easy on her punishment today. It wouldn't work, of course, but I did appreciate the effort.
