I didn't see Mengxia again for the rest of the day. That didn't mean she wasn't on my mind though. In fact, I thought of little else all day, and found it really hard to work.
Towards the evening, I received a Snapchat from her captioned "Missing me?" showing a low selfie of her face, her full lips and the top of her cleavage. It got worse a few seconds later, when I received another message, this one saying "I think he's going to like what he finds, do you?" showing a picture of her slightly bent over, wearing a very short red skirt, riding just high enough to reveal her lack of panties - panties that I was wearing right now, under my work clothes. She drove it home with her final message, another selfie showing her laughing, with her fingers in the universal "small penis" pose. The caption said "Too bad you have such a tiny, pathetic dick."
At that last image, my hands had started down towards my panty-covered genitals, and had started stroking myself without realizing. Without being able to control myself, her vicious dose of humiliation caused me to cum, cumming spurt after spurt into Mengxia's panties. They were so skimpy that the cum went right through them and started staining my slacks. I got my pants down just in time to prevent the worst of it, but was too late to stop the cum staining the seat of my office chair. My phone beeped again. Mengxia had texted "You'd better not cum tonight, I forbid it. There'll be hell to pay tomorrow if you do." I gulped.
I sat at my desk for a moment, feeling ridiculous in my cum-soaked panties, partly stained slacks around my ankles and my stained office chair. From this side of orgasm, our little arrangement didn't feel like such a good idea any more. She was my intern! We were supposed to have a healthy manager-employee relationship. Instead, I was taking orders from her and was jeopardizing my career.
I stayed at the office until long after my usual time, to avoid running into people on the way out. I took the panties off completely and put them into my bag, to wash later. Since Mengxia had destroyed my boxers, there was nothing for it but to go commando, putting my slacks on over my bare cock. It would have to do. Luckily, I didn't run into anyone on the way out of the office. I decided to take Uber home instead of the metro, to avoid people noticing my little "accident".
Back home in my swanky, one-bedroom penthouse bachelor pad, I hurriedly stripped of my clothes and started a load of laundry. Despite myself, I took Mengxia's panties out of my bag, and handwashed them carefully, soaping them and hanging them to dry in the bedroom. There was no question of wearing them anymore, of course. I would tell Mengxia politely the following day that I hadn't been feeling very well today, and had agreed to and done things that I really wouldn't have ordinarily done. And that would be that.
I spent some time writing, and working on my projects. After an hour and a half, I went to the bathroom and fetched my laundry, taking it to the bedroom to fold. I then picked up Mengxia's panties.
At my first touch of the soft material, the memories of that morning came rushing back. How Mengxia had dominated me, so effortlessly, so easily. How I had worshipped her feet, how she had mocked my penis, how she'd taken her panties off to give me...
I looked down. Without realizing it, I had been pressing her panties against my cock, and rubbing gently up and down. I was cumming again. Incredibly, almost as much as I came the first time. This time, the cum stained her panties again and then shot out in large spurts all over the bathroom.
"Fuck me," I said aloud, frustrated. What was wrong with me? My arousal had left me, I was back to my original state of hating myself and what Mengxia had done to me.
I cleaned up the bathroom, and then rewashed the panties and hung them up again. I then forgot about them until after dinner, right when I was about to go to bed. As I was about to go to bed, I saw her panties again, hanging on the rail right where I had left them. I touched them. They were dry.
Surely it couldn't hurt to play with them just a little bit? I would take them into bed with me and admire and feel the material. I had never touched a woman's underwear without her being there, after all. All in the name of science...
At this very moment, Mengxia was having passionate sex with a man, somewhere in this city. A man who would see the same view that I had seen that morning, but in more detail. Perhaps at this very moment, she was on all fours, moaning as he thrust his cock into...
It took longer this time, but I came again, this time onto my bed. I cursed, turning the light on. My arousal had left me again.
---
I was exhausted as I got into work the following day. I had had to stay up late waiting for the panties to dry. This time I had firmly stuffed them into my bag, determined not to cum again. I yawned as I unlocked my office door, and seated myself at my desk, and started checking my email. Work progressed in a fairly uneventful fashion, with not too many calls to attend to. Noon came around pretty quickly, and I was just about to go and get some lunch when there was a knock on the door.
Mengxia walked in without waiting for an answer. She looked a little more troubled today than she had the previous day.
"Hi Mengxia," I stammered, "how has your day been so f -"
She cut me off with a wave, and walked straight towards me and around the desk. She looked down at my desk chair, her sharp eyes immediately spotting the conspicuous stain I had not yet managed to clean from the previous day. She sighed, audibly.
"So you jerked your little dick last night." It was a statement. She looked profoundly disappointed as she said so.
I felt suddenly bad. "I'm sorry, Mengxia. The pictures you sent me yesterday were so hot and really got me going. I couldn't control myself."
"How many times?" she asked.
I thought back to the previous evening, remembering how many times I had lost control. I felt ashamed. "T-twice," I said, timidly.
She looked at me levelly. "slave," she said quietly, "none of this is going to work if you lie to me. You can't undo what you did yesterday, but at the very least be honest. How many times did you jerk your little prick yesterday?"
I cleared my throat. "Four times," I said, "once right here, and then three times at home."
She stared at me, and then suddenly started giggling. "Four times!" she choked out, "wow, I don't think a lot of men can do that! You must have been really motivated. What got you going?"
I told her the story of how I'd been at work when I'd got her messages, and how her panties had turned me on so much. She listened attentively, standing only a couple feet away from me. I ended my story, staring at her expectantly.
Mengxia sighed again. "I supposed you're not to blame for what happened, slave. Yesterday's experience was probably very stimulating for a submissive small-cocked sissy like you." As always, I shivered at the casual name-calling. The fact that I was supposed to be her manager seemed to have been consigned to history. "Add to that the fact that you were wearing my panties, and it is not surprising that you came so many times."
I relaxed just a little bit.
"However," Mengxia said, her voice growing a little more stern, "it won't do at all. The core of your submission is redirecting your sexual energy towards serving a dominant woman. I understand that you will occasionally be very turned on by our experience together, and that's OK. But you can't come. I won't be able to get the best out of you if you do. You will be cheating yourself, too. You won't be able to submit as deeply as you could.
"I'm sorry, Mengxia," I said, honestly, "I promise it won't happen again."
Mengxia's eyes softened, and she took a step towards me, placing her hand on my shoulder. "See?" she said, her eyes scanning my face, "already you have forgotten how to address me, and I told you what was expected just yesterday! All that jerking off has drained off your submissive energy."
I realized with a shock that she was right. How had I forgotten? "I'm sorry, Miss Li. I will not jerk off in the future unless you allow me too."
Miss Li smiled. "slave," she said, in a voice that indicated she thought I was being silly, "after what you did last night, do you really think I am going to take your word for it?" She reached into her bag as she spoke these words, leaving me to contemplate what she'd said.
Miss Li withdrew the package, and unwrapped it with a flourish. "What I'm proposing may seem extreme, slave boy," she said, as she finished tearing off the wrapping paper, "but I am convinced that it is the only way to make a true slave out of you."
She set the object down onto the desk, and motioned for me to take a look. It was a chastity device, so familiar to me from the porn videos that I watched. She opened up the box, revealing a translucent pink cage and ring. "I anticipated that we might need something like this yesterday, right after I sent you those videos. I had to place a custom order at the toy store downtown, they don't usually make cages small enough for you but they were able to get me a special prototype this morning. I billed it to the corporate card." She grinned. "I believe that, as my manager, you're going to need to approve that expense!" She must have seen the shock on my face, because she quickly added, "Don't worry, the expense is going to show up as a visa application expense. I don't want to ruin your career"
