John walked into the house with the new bondage kit and the old toy bag. He called out, “Mona?”

Mona emerged from the kitchen, completely nude.

John said, “It’s good to see that you have been obedient.”

She came over and hugged him, and caressed his obvious erection. “It’s good to see you, and that you are happy to see me. There were two things delivered this afternoon; I assume you arranged for them.”

“Yes, I did. Where are they?”

“The pillory wasn’t wrapped. I had them put it in the basement, where we’ve played before. It’s all set up. The other package was a big box. I took a guess and had that put in our bedroom.”

“That was a good guess. I have something else here that I’m going to put on you now.”

Mona stood as John put on the belts, cuffs, and straps just like the ones used on Delia. He left his wife’s hands relatively free, with only long straps locking them to her collar. “What do you think of it?” he asked.

Mona tugged a bit here and there, tried walking and sitting, and said “It’s secure, but the way you put it on I can work and move around OK.”

“Good. You finish dinner, and I’ll set up the big box in the bedroom. By the way, you have on the same set that Delia does now, with a little more freedom for the hands.”

“Like daughter, like mother, huh? That reminds me, I haven’t seen her since her enslavement. I’d like to go down there tomorrow.”

“That’s fine. I won’t unchain her for your visit. If you like, you can take her to a coffee shop.”

“If you won’t unlock her, she’ll have to go nude!”

“Correct. Part of being a slave. At least, part of her training. If you don’t want to go to a coffee shop, there are slave bars that serve lunch.”

“I’ll think about it.”

John went upstairs and unpacked the pole. It was simple to assemble, and the device batteries were already charged. He figured on putting her on it for an hour after dinner, playing with the remote, and watching her reactions.

A while later, Mona called him to dinner. He came down dressed causally and comfortably. He also brought some nipple buzzers, which he attached to Mona. It made her a little distracted over dinner.

He asked her afterwards, “Did you try the pillory?”

“I thought about having them test it on me, but didn’t. Before I answered the door I put on my robe, but took it off when they offered to place the pillory. It was exciting. They enjoyed looking at me. After they left, I tried out the holes. The neck hole is fine. The wrist holes are just bigger than my wrists.”

“Good, it fits. So two men saw you and it excited you?”

“No, one man and two naked slaves.”

John then rose and changed her bondage, connecting her wrists to her elbow cuffs behind her back. He led her upstairs by her vagina, by palming her mound and inserting his middle finger, and tugging her along. When they reached the bedroom, he closed the door behind them and released her. He pointed at the pole and said, “Does that look familiar?”

She looked and said, “Yes. It’s like the pole downtown.”

“Walk over and place yourself over it.” After she did, he said, “Notice the red plastic dome by your right foot. Pump it with your foot.”

She pumped, and the pole began to rise. She understood, and kept pumping. As the pole device reached her vagina, she maneuvered it into her, and kept pumping. Even as the saddle reached her, she kept pumping until the pole wouldn’t rise any more. John smiled. “Now, try to get off the pole.” She tried lifting her legs, lunging back and forth, and jumping, but her extended-foot position didn’t give her any leverage to get off the pole. She admitted defeat.

John smiled some more, and pressed buttons on a remote control. The device buzzed. John took a plastic part and put it on the saddle so that it pressed against her clitoris. “We’ll leave it there now. You’ll have to take care to get things straight as you pump so that it hits the right spot.” The buzzing then reached her clitoris and made her gasp — and wet even more.

John played with the control, turning the vibrations up and down and noting when the buzzing seemed to stop pleasing her. He turned it up more to see where it started displeasing her. He turned it up more to see where the discomfort turned into pain, then reduced it to a pleasant level. “That’s now the default vibrator setting.” After that, he turned off the vibrator and started playing with the electrical options. The lower settings didn’t do anything for her. Slightly higher settings tickled pleasantly. When he started routing the current through the clitoris stimulator, it made her moan and press against it. He tried the various internal electrode locations, noting which hit the more sensitive spots. Selecting those spots, he started turning up the voltage, again noting where it stopped being pleasant, where it started being uncomfortable, and where it started to hurt. He left it at the hurt level. “Are you regretting it yet?” he asked, watching her face closely.

“No, not much. This hurts a little, but I’m really wet and turned on.”

John turned the vibrator back on and left the electricity on the hurt level. After a while, he asked how it felt.

“It feels good. The vibrations seem to ease the electrical pain.”

“That’s what the instructions said would happen for most women.”

He then turned off the electricity and the vibration, then pushed buttons that started the device twisting inside her, just a little. She liked that. He turned the amount of twist up and down and varied the speed of the twist, noting her reactions down in a table that was part of the device handbook. She seemed to like all of those variations. After that, he made it thrust inside her, just fractions of an inch, varying the distance and speed. She liked all of those too.

He shut off all of the motions, then stepped in front of her and looked her in the eye. “There are other functions that the device has, too, and you won’t like all of them. Some are designed not to be liked. I’m going to try some of those now. I want you to look me in the face and say that you approve of me trying them, that you want me to try them, and that it is part of your deal with me.”

She looked apprehensive. She had an idea of what was coming, and was scared. She loved and trusted him, though, and knew he wouldn’t harm her, or cause her too much pain, or for too long. After a deep breath, she said. “I gave you unlimited authority over sex. This is sex. This is part of your authority over me, according to my request. I approve of your trying the unpleasant functions of the dildo, and I want you to try them. I’ll just ask you to hold me afterward.”

He smiled, and pressed a button on the remote.

It felt like a hot poker on her clitoris. It lasted almost no time at all, but it got her to lurch halfway up the dildo, and she heard herself scream. The pain disappeared immediately, leaving her breathless. Her husband embraced her and kissed her, and waited for her to speak.

“That was the most painful thing I’ve ever encountered. Please don’t do that again.”

“That sounds like a condition,” replied John.

“No, it’s a heartfelt plea. If you decide to do it again, you’ll do it again, but I’m begging you not to.”

“OK. Just checking. That’s reserved for extreme situations where you really need and deserve it. The book says that repeating it on a two-minute cycle for an hour is extremely effective.”

She shuddered at the very thought. Then she saw him pressing a button on the remote, and tensed up for a repeat. Instead, she got a sensation of something moving up and down the dildo, inside her, fast. It was a moving tingle. No, more than a tingle; it would have been painful except that it moved so fast. It started to excite her.

“So you like that. Good. It’s a reward, then. In this case, a reward for taking the shock so well.”

He stopped the pleasant feeling, pressed a few more buttons, and the dildo started to warm up. It felt good. “This is the highest setting. How does it feel?”

She answered, “It feels good. It’s like a hot tub inside me. I wonder if it would get unpleasant after a while.”

“It’s possible.” The warmth started to fade, slowly. It was followed by a sharp shock that caused pain, but nothing compared to the clitoral bombshell. She gasped, and wondered if she had just agreed to a life of pain; she hadn’t expected that from John, but you don’t always get what you expect. John was watching her face, and guessed what she was thinking. He approached, kissed her, played with her breasts, and said, “I’m not planning on using the pain settings. I admit that watching you experience that last one was interesting, but not all that interesting. The big one was painful to watch. I don’t intend to use it again. The manual suggests that I try all of the functions, for several reasons. One is that some women love some of the supposed punishments. Another is that if the wielder ever decides that punishment is required, you want to know ahead of time what is appropriate. Another is that the device stores some response information and keys it to the ‘imbedee’ so that it can alert the wielder to abnormal responses. The more things that are tried, the better the ability of the device to detect bad results. A big reason is that the slave, and you are playing the slave here, should understand what the device can do and what she may be subjected to. The biggest reason is that the wielder is master, and should act like it. I agree.” She got a second shock, stronger than the first, but the recent memory of the clitoral blast made it feel less intense. He went on, trying things, asking her how it felt, entering numbers on the remote, and moving on to other torments and delights. About half of the things he tried felt good; some were wonderful. He didn’t tell her if they were meant to feel good or whether she just liked a punishment. The cumulative effect was making her horny beyond belief.

After a while he seemed to have reached the end of the list of things to try. He set the dildo on a low warmth, with electrical tinglings up and down and on her clitoris, with small thrusts and twists, and a medium level of vibration. “Now we find out what a steady stimulation produces. I’ll be back in a minute.”

She said, “You’re leaving me alone on this?”

“Just for a minute. I have to get some reading material.”

“You’re going to read?”

“Looking at you writhe in pleasure, or in pain, for that matter, is a pleasant way to spend an hour or so, but this will be a bit more boring. The purpose of this exercise is to find out what level of stimulation will get you the hottest and keep you there without letting you orgasm. It is also a way of calibrating the device to detect upcoming orgasms. It is in your best interest for that to be accurate. The thing can be set to reduce stimulation when an orgasm approaches, or to turn it up, or to apply a shock. It also detects orgasms, and can be set to react to those too. This will be a period of calm, slow stimulation for you, and I want to read the paper.” He tweaked her breasts and walked out of the room.
