Princess Luna turned to her other side, it was seven in the morning. Some ponies were the kind who just wakes up and feel energised until dusk. She wasn't one of them, she was one of the other ones, who walk like a zombie until they get some coffee in their system or just wait to be afternoon.

The princess was also bothered by another issue, thousand years ago she abandoned her subjects, turning her back on those who depended on her by revolting agaist her sister and in the end, getting banished. Her conscientousness gripped her stomach each and every morning. Her loyal subjects reminded her that she is forgiven, but she still had to do something about her guilt.

She had to do something about it. She must punish herself, if nopony else is willing. She must do penance to be absolved from her crimes, with the fitting punishment.

She had her loyalists humiliated, so she must humiliate herself: she will forgo underwear and instead wear vibrators this day, no matter what.

Energised by her approaching absolution she jumped out of the bed to begin her day. She put on a long, dark blue skirt and a black tank top. It was strange, being totally covered but still feeling naked, but she had no time to savor this weird state, with her crown jewelries and a strong leg band on she was ready to go.

Canterlot's torture chamber was less a torture chamber and more the place where the princesses did their private stuff. It was filled with both old and modern instruments of various uses, sex toys mostly, but there were some racks, abandoned school projects, seriously messed up poetry, bondage furniture, ancient issues of Playcolt and Twilight's collection of latex gloves... Luna searched in the sex toy and soon found a dozen of bullet vibrators and a roll of tape.

Quickly she fixed one of the vibrators to her clit and pushed two others in herself. She hadn't used any lube, her subjects hadn't seen it coming, why should she expect it prepared. She took a look at the remotes which had settings form zero to four, with a button of osscillate and another of random intensity. She pressed the random intensity buttons and tucked the remotes into her leg band.

The vibrators came to life, the one on her clit was in dormant state the first in her pussy was on low and the other was on maximum vibration. She walked with wobbling knees as the toys sent waves after waves of pleasure through her body, but suddenly it stopped and a loud knock was heard from below Princess Luna. The vibrators have fallen out.

"This won't do it," thought Luna " I need to wear something else to keep them in."

She went back to the sex toys and dug out a thick leather belt with rings and a hemp cord. She wraped the belt tightly around herself just above her hip and tied one end of the rope to the ring on the back. She reinserted the vibrators into her pussy, they went in easier than the first time, because her sex was already glisteningly wet. She had five pieces of rope hanging behind her butt. She pulled three of them between her inner labias to keep the toys in, the other two cords went between the inner and outer labias. She pulled the ropes taut and tied them to the frontal ring. They painfully dug into her delicate flesh causing a continous discomfort, but she had to withstand it. She had to.

The council stormed into the throne room, the vice-captain of the royal guard was yelling with the grand marshal, the rest of the council was following them arguing incoherently. Princess Celestia wasn't in the room, might not be in the castle either. Princess Luna had to solve the situation before it gets out of hand.

She stood up to show dominance over the councilors, and to relieve some pressure from her aching pussy, as the ropes dug deeper when she was sitting. She felt that all the vibrators were on low setting, which made communication managable. She walked down from the pedestral where her throne stood, with each step reminding her to the ropes between her legs as they scraped her most vunerable bits.

"What's the meaning of this?" yelled Luna.

"The grand marshal is out of her mind, your highness. He is suggesting that we allocate all resources to hunt down changeling spies. That would leave us open for sabotage and assassination" said the vice-captain.

"The his idea is insane, your majesty. Sooner or later they will find an opening, if we don't hunt them down first. Perfect defense against espionage does not exists" exclaimed the grand marshal.

The other councilors either stood by the side of one or the other.

"Let me think, the rest of the council may go" said Luna as she fought the urge to moan.

The vibrator on her clit decided to torment the poor princess by swithcing to maximum, and the other two changed themselfes to high.

Luna had to concentrate not to collapse to the floor, she felt an orgasm building in her. Her only hope was to walk back to her throne and ride out the orgasm there, because she couldn't keep standing, if it hits her now. She took the first wobbly step toward her throne, brushing her clit against the rough hemp rope, further hastening the coming orgasm. She hang her head low, not letting other see her fight with her own body. With each step she took thousands of nerve endings lit up from either pain or pleasure sending waves of distracting signals to her brain.

"Your majestry, are you alright?" asked the grand marshal visibly concerned.

"Yes, hhnnngh... yes, we are" she anwered with trembring voice.

She finally reacher her salvation. She humped down to her throne and held her head in one of her hand. She is cumming. She tried to fight the urge to pant, to show any sign of her self-humiliation. But alas, her breathing quickened and she drooled out ofher mouth. Her entire body contracted as she rode through the orgasm.

As she recovered from this terrifying yet arousing experience, she noticed that neither of her guests are staring at her, but instead a particulary uninteresting spot on the marble floor with a heavy blush. One of the two royal guards was watching her, with some concern and much desire. The stallion was staring at her chest which now featured two small numbs protruding from her breasts. He instantly averted his gaze as the princess turned to him.

Having collected some decency, Luna answered the question "Vice-captain, you are to use resources to strengthen the castle defense against spies, but do not over do it on the other hand. The rest of the resources goes to the grand marshal, who uses it as she wants to hunt down spies."

"Understood, your majestry" they saluted.

"If there is no other question, dismissed" finished the conversation Luna.

With some time passing the vibrators changed to lower stimulation and allowed the princess to act somewhat normally. The wicked guard was still trying to shoot some glances to the princess erect nipple. After all, you don't see something like this everyday.

Luna was at some place else, evaluating her own punishment, she concluded that this minor piece of self-humiliation was negligible compared to her crime. She had already began to formulate a new part of the penance.....
