Silent Moon

With a snap of her fingers the piercing on her disappeared. She had changed the way she handled her private parts. She used to care for it, only allowing the softest fabric to touch it.

But now, she totally changed her selection of underwear. Her panties, which no longer fulfilled its original purpose, was made out of burlap or jute and only shielded her clitoris and its hood. She also wore only two smaller than required, so the rough rope straps slipped between her folds and asscheeks, irritating them.

Her bras were no different, they were made out of a rough material that becomes translucent when wet. They also had tack, metal spikes and protrusions in the place where her areolas are.

On an average day she wore these as underwear, on days she felt extra risky she attached an iron weight to her clit, but that was just the usual. Some times she just took a needle and pushed it in her her clit and left it there for the whole day.

There was a rumor in the castle that Luna loves the taste of ginger, she drank ginger tea and asked for a huge ginger every morning. She had ginger scented candles and air fresheners.

But Luna used them to train herself, the burning feeling from the ginger was only unbearable if she pressed the juice out of the root. Therefore if she doesn't clench her hole, then she is safe from the agony.

Obviously, it was easier to say than do: first the ginger still irritated her butthole from the inside and outside even when not being pressed, second she had duties to fullfil like attending ceremonies where she has straighten up and stand like a stake and press on the ginger.

There is a private garden in Canterlot, where she can do whatever she wants because a powerful illusion guards the place, seamlessly distorting anything that happens inside.

Every morning before breakfast and figging, she went out to the garden and began her training there. She used a magic to spread her vagina open, right down to her cervix. The she put a half hollow ring in her pucker.

This object was call a slave's ring, basicly it kept her asshole open. Her's had several other functions, it was sealed for liquid and solid matter, so only the wind can pass through and make her feel even more exposed. Her magic in her pussy served the same purpose.

The other difference is that her ring had a soft compressable sponge in the ring which can be soaked in a fluid and only release it when pressed on. She usually used ginger juice, but today she used the undiluted spicy essence she brought to the tower.

She looked at her pussy and saw a swollen red mess from not having orgasms despite the daily trainings she recieves. She cast a curse to increase her sensitivity by three times, in that way she will force herself to admit her deviances to her sister or go mad from denial.

This curse includes all sensations: arousal, pain, irritation and pleasure. One can only break this curse by having an orgasm, so as soon as she tell this to her sister she will be free from this vile magic.

She increased the wind in the garden to a strong breeze and began trotting around the local statues. She felt that the air around and in her privates cooled to a freezing degree and yet not reduced her ache for an orgasm.

Her poor pucker was on fire, or at least she felt that way when she involuntarily pressed on the ring.

"Luna, stop!" she heard a angry voice yelling at her.

She imediatly slowed down, and pressed the ring so much that a little essence flowed down on her pussy and began burning it.

She looked around and saw Celestia throwing a death gaze on her.

"When I banished you, I was overtaken by guilt, guilt that felt until right now. Seriously you thought that I can't see through your illusions and misdirections, sister" yelled Celestia.

She was out of herself, nopony had seen her in fury, just mildly annoyed sometimes. But now, it was safe to say that she was enraged.

"I put the same curse that hold you because of my guilt, and you ruined our reunion. I am not able to cum until I make my own sister cum" a slight hint of dismay and hopelessness sneaked into her explosion on her sister.

"How could I know, my sister, I didn't... I shouldn't... How can I make this right?" asked Luna at the brink of panicking.

"You will dress as I say, do as I say and sleep as I say. Any disobidiance and I curse you that a whip will strike your clitoris whe somepony says the in Equestria!" commanded Celestia.

Luna nodded in agreement and prepared to disspell the magic holding her pussy open.

"Leave it, you will summon the rings in your labias and clit and attach weights to them, fifty gramms on her clit and hundred on your labia and run until I say stop" Celestia thundered and gave Luna the aforementioned weights.

Luna almost cried after the dozenth circle she ran, but suddenly Celestia said:

"Stop, have you cursed your breasts?" she asked the rhetorical question. "No, then do it or I do it with a few other curses that will make them so sore that you will constantly cry!"

Luna gathered her magic to perform the horrid spell and with a black flash her tits became engulfed in the malevolent magic.

"That won't do it, come here!" Celestia yelled another command.

Luna walked up her sister and when she arrived Celestia slapped her left tit from waist, putting all of her mass in the strike.
Luna fell backwards and began sobbing from the stinging in her breast, which soon sported a red mark of a hand.

"Pathetic, you can't even stand the punishment that you get from causing harm your sister. Meet me in my room in an hour, naked and hand bound behind your back" said Celestia then teleported away.

Luna was in state of weird content, her own sister now became her tormentor and judge, dishing out punishments that both know she deserves. A strange thing came to her mind: she was thinking about that Celestia catches her and punishes her.

"She might read my mind" thought Luna.

She skipped through the castle naked and with her hands bound in a reverse prayer position. She felt exposed more than ever, she couldn't fly from the bondage and anypony who happens to come by sees her naked.

Finally she reached her sister's room, the door was slightly ajar. Celestia stood in the middle of the room, with a serious expression.

"Answer honestly, do you accept your punishment from me? I probably was a little out of me in the garden l, but we will only continue if you say yes" said Celestia.

"May I ask a few questions first?" asked Luna meekly.

"You may"

"Haven't you came in a thousand year?"

Celestia lifted the white skirt she was wearing and revealed her marehood. It was pulsing with unfulfilled lust and denial.

"Not once in a thousand year" answered Celestia sadly.

"What have you seen, what was I doing with myself?" Luna proceeded with her questions.

"Everything, the crotchrope and the vibrators, the fucking machine in the tower, your journey home and your daily exercises. Everything..." said Celestia.

"What if I say no?"

"I will forgive you, I won't reprimand, punish or force you to punish yourself. We both live our life without an orgasm there on."

"Then I say yes, I accept my punishment from you."

"Good, I decided that because I don't have enough time on my hand, the duty to punish you will be handed down to the master-torturer" decreed Celestia.

From the shadows, a hooded figure stepped forward:

"If we can begin, then just say the word Her mayestry" he said.

Luna's face burned from embarrasment as the master-torturer measured her with his eyes. Celestia nodded and teleported away.

"What the hell does a torturer do in Canterlot, we ceased to torture ponies more than a thousand years ago, aren"t we?" asked Luna.

"Mostly being bored, scaring adventurous fillies and colts away from dangerous places and chatting with the other holders of redundant titles" said the torturer." By the way my name is Rose Thorn"

"Isn't that supposed to be a mare's name, not a stallion's?" asked Luna.

"I was expected as a filly... May we begin your penance?"

"Yes..." answered Luna.

"I lack the necesary information to proceed, how should I torture you?"

"Like we used to do it on ourselves" said Luna.

They talked about the methods she used, the tower and the road home. Rose listened to it attentively and said she has the perfect plan in his mind.

Luna was still bound when Rose took out a pair of panties from a box.

"We create a link between our minds, so you can send us commands" said Luna and cast a spell. "We also allow you to manipulate the piercings on us."

"Okay, put this on and go back to your room, dress and go on your day" he handed the panties.

Luna used magic to put it on, because she was still bound and naked. The panties was made out of silk, but it had portals at the crotch area. She felt that neither her marehood, nor her asshole was covered.

Luna was on the way to her room when she felt that her piercing appeared. She stumbled a little, but continued walking.

When she finished in her room she felt the usual sensation of ginger on her pucker, but instead going directly in her ass, first Rose rubbed her entire sex with it and then inserted it in its proper place.

Luna winced from the burning and bent forward.

"Straight back, stand in one place" a command came on the link.

At the same time she felt that her clit was rotated to a painful degree by the piercing in it. She quickly assumed the position and waited for the pain to stop, which eventually did.

She felt that a lubed thin metal rod was being press at the opening of her urethra.
Six bullet vibrators were affixed to her pussy and set on maximum, the rod also began vibrating.

He inserted a dildo in her hole, which qas coated with the spicy essence and it immediatly began burning her. She was writhing on the floor in pain and euphoria. She was eternaly denied and stimulated, just as she deserves...
