Luna turned to her other side, having trouble sleeping in the past few days. The initial relief from her self humiliation have lost its effect, but she was reluctant to begin her next sentence. She was afraid from her own punishment, the twisted idea that have popped into her head in the first night she could finally sleep well. But now, she has to do it, wear that vile contraption that she so eagerly constructed.

She got up from her bed and began to walk down to the torture room. The soothing calmness of the night was disrupted by the rhytmical clapping of Luna's hooves, and as a compensation, she sent a shooting star through the sky to entertain those who feasted their eyes on her beautiful stars. The nightguards stood stalwartly all over the palace, glancing at her princess, as she was wearing a nightgown that barely hid anything. The fear from that device that was waiting for her down there was making every step feel like mile with her legs made out of lead, but isn't fear makes the punishment more effective?

The torture chamber was in its usual state, abandoned and filled with things that the world didn't have to know about, her device was no exception. She dug out a small box from behind the Playcolt magazines and opened it. The box contained thick panties made out of leather like material, its inside however was fill with various gadgets of torture: small needles pointing toward her most sensitive parts, thin metal rods that can clamp on her labias and pull them taut, rough brushes, spikes, metal bulbs with either smooth or sandpaper like heads, and a ring that stretches the entrace of her vagina but leaving the rest of it unstimulated and various other tools of discomfort.

She was sweating from the dread and the curiosity of what her next sentence will bring, and without hesitation she pulled up the contraption. She took a lock that will only open after twentyfour hours later from when it was locked. With a quick activation spell, the panties sprang to life. Two rods extended themselves below her clitoral hood and extracted her love button before locking themselves in place, the ring stretched her entrance to a level that was almost painful and needles alinged themselves to point at their target. Her anus was safe either, a hollow metal half ring invaded her asshole without any lube and positioned itself around her sphincter. She quickly locked the two straps which lead above her hip bone to the front of the panties, preventing any removal method that wouldn't break her hip. She just have to wait a day to be free.

There was no way she can sleep in this thing, she had to spend some time until the day starts. She looked at the clock which showed one in the morning. She knew the first time she sits down her contraption will activate. She took one of the older issues of Playcolt and took a seat at the table, begining her punishment.

The panties functioned as it was intended, a smooth head bulb with numerous spikes on its side pressed itself into her urethra with the spikes scraping the tissue around her hole with every move. Luna leaned forward from reflex, which proved to be a mistake when the bulb with the spikes withdrew from her peehole, but instead a needle jabbed itself into her clitoris, its force wasn't enough to pierce the skin, but Luna felt a sharp pain from her vagina too as another needle came into contact with her sensitive wall.

She winced and leaned backwards from the pain, which only worsened the situation as the smooth bulb quickly went in and out of her urethra, several needles pricked her vagina's wall and at last she reached the position she wished to take. To her surprise, the ring in her anus contacted a small high intesity vibrator, which sent tickling waves to her butthole. Luna jumped from the sensation, which made it stop.

Her torment wasn't over as the contraption, the tickling has passed but it left behind an itch that she couldn't scratch from the belt. Even worse the thin metal rods clamped on her inner labias and forced them into a taut W formation. She couldn't sit, so she thought she might just go for a walk.

With every step with one leg she took, she felt that the belt pulled at the other labia as countermeasure. She just have to make less bigger steps to fight it. The belt proved her wrong once more, with each movement a little pin jabbed at her clitoral hood from the side of the front leg and the rods pulled stronger. If that doesn't work, lets try smaller steps to make the pulling less torturous. This idea was aslo futile as the belt pushed two brushes to side of each labia, grinding on her stretched flesh continously.

"This day is going to be interesting" thought Luna.

"This cannot be," panicked Luna "they are coming, I'm so stupid. Eeep!"

The thin rods clamped her labias painfully as she stood up from the chair. A diplomatic envoy is arriving today to canterlot and the royal sisters have to greet and spend time with their guests.

"Okay, okay. Just calm down, you just have to pretend that your pussy is not being tortured by your own vile creation." thought Luna "That's hard enough."

"Luna, come, they are here!" yelled Celestia.

Luna ran, with each step the thin rods pulled her labias, brushes scratched her most sensitive spots between her folds, her clitoral hood sliped on and off the two spikes on the rods that prevented her clitoris from retreating. This was the worst form of torture that the contraption has done to her today. She quickly teleported herself next to Celestia to avoid any more of it. She was gravely mistaken as all of the needles in her panties pricked at her then quickly retracted as punishment for teleporting and for causing discomfort to her subjects by getting banished.

"Luna, you have been fidgety today, everything allright?" asked Celestia.

"Yes, I ma alright, just a little nervous about the envoy" lied Luna.

"I thought so" smiled Celestia.

The diplomatic envoy ceremoniously arrived at the castle, where the two royal sisters greeted them.

"I hope your travel here was enjoyable" said Celestia.

"Yes, it was but the Equestria has many fair sights that took several hours to admire," said the diplomat "and we became quite hungry in the process."

"Of course, the lunch is done and waiting to be served, come let's have a feast" said Celestia.

The princesses and the diplomats went to the balcony where a set table and covered plates awaited them. They sat down to the table and the servants lefted the lids from the plates revealing the delicious dishes under them.

Luna was in some place else, the thin rods released her labias, but she designed the contraption to randomise the torture methods every time she stands up, only the bulb that just went in her urethra again couldn't change. She had to act normal, unless she would be discovered before the diplomatic envoy.

She leaned forward to grab her utensils, the smooth bulb slipped out of her peehole, but instead a sandpaper headed one went under her clitoral hood and came out scrapeing her delicate flesh. Luna winced in pain and returned to sitting upright, causing the smooth bulb to invade her urethra again with the spikes picking at her stretched flesh around it.

"Princess Luna, it's good to see you, I heard tales of your beautiful nights and on the way here I was struct by awe by looking at them" said the diplomat.

The addressed princess had trouble concentrating, her marehood is being abused at this very moment, but after some very hardly prevented grunts she answered:

"Thank you, mister?"

"Kalap al-Abaster, I was born in Saddle Arabia, if you're wondering about my name."

"I really spent time on maintaining the night sky, I heard in Saddle Arabia there are numerous astromoners, astromancers and starcasters."

"Yes there are many of them, but I was really astonished by the fluorescent color of the Everfree forest at night. Its welcoming colors that we couldn't see during daylight were hard to resist, but we know how dangerous that forest is."

"Thank you again, there are only a few ponies who stand bewildered before my night's colour" said Luna as she tried to not show that the vunerable skin between her folds are being tortured by needles.

The rest of the the lunch is spent by listening to Celestia and al-Abaster's diplomatic speeches, Luna fidgeted ever so often, changing positions every five minute. After the feast the diplomat was shown his sleeping quarter, but Celestia had other plans for Luna to do to today.

"My sister, I would like you to accompany me in the throne room, several mayors requested a hearing today and I wish that you would participate in the occasion.

Luna's hope to spend the rest of the day alone has evaporated that instant, and with further discomfort, she came closer to her redemption.
