After retrieving the results of her last experiment from Vinyl Scratch, Twilight wanted to try something similar herself. However she was too afraid to do so with one of her close friends... So she's going to try it on Luna in a dream.

This is a sequel to Vinyl's lamia story, and yes there will be more, as well as a sequel to Vinyl and Octavia's story so don't panic I haven't forgotten. Also the idea was requested by Dark-Shadow, he suggested a Twilight x Luna lamia story so... Here you go mate! :)
Note the sequel to this, when I get around to it, has already got a chosen character, so that's taken.

Also, is it me or am I doing a lot of short stories lately?

Twilight's night time experiment

Twilight continued to flip through her various notes, she had turned one of the higher level rooms of her new castle into a form of lab since she had begun making the lamia potion. Chemistry sets, all full of the lamia potion, sat along the edges of the wall, awaiting a pony to drink them along with various sketches of plants and instructions on how to make more. Twilight was currently in her lamia forming, having recently taken more of the potion for this next experiment, her tail was mainly purple like her coat and her belly was midnight blue with the pink and deep purple highlights, she had it spread around the room, but had made a sort of seat beside her desk. The notes of the effects of the potion on herself and its powers, namely hypnosis, on a few ponies she’d managed to convince to try it, were spread out. In one corner however was a note pad with a small picture of a bright white mare with an electric blue mane, the first pony Twilight had given a second potion to other than herself, not likely to be the last, Vinyl Scratch.

Twilight lay back on her tail and stared up at the ceiling, thinking. She had wanted to see how far her hypnosis could go but was always afraid of going too far with a stranger, less they judge her. She had thought about hypnotising her friends to do that, which she had told Vinyl she had done, though she had not gone anywhere as far as the DJ… She didn’t want to ruin their friendship. She needed a pony she could try the full extent of her powers on, without her really believing she was doing those actions on purpose… Like if she were dreaming… Dreaming…

The idea came to Twilight so suddenly she almost flipped forward onto her stomach as she sat up. Of course, Princess Luna. She patrolled pony’s dreams at night, and in this form she had had dreams like this… If she could somehow make Luna visit her dreams at night. Twilight grinned pushing aside several notes to clear a space. Grabbing a fresh piece of paper Twilight began to formulate a plan for how she’d go about this, she’d need to wait for night for a start so that gave her plenty of time to think.

Canterlot was slowly emptying as its citizens returned to their cosy homes, ready for some peaceful sleep. Luna sat upon the balcony that was attached to her room, guiding the moon into the sky as her sister, from her own room, lowered the sun. They had done this for so long, even before Luna’s imprisonment, that it was simply natural. Luna’s moon and her patchwork art of stars began to twinkle, casting their gentle glow across Equestria. Luna smiled slightly then retreated back inside her bedroom. Since the Canterlot incident Luna had taken to sleeping like any other pony at night, and had even learnt to still traverse dreams whilst asleep, which was much easier than exhausting herself, she was helping ponies but still resting.

Luna lay upon her large bed and curled up sighing contently as the darkness of sleep slowly took over. Luna opened her eyes but knew she was in the land of dreams, her own to be precise, though very few ponies were likely to have rows of doors with various cutie marks and colours over them. Luna had managed to make her dream doors line up in a form of order, certain dreams that were innocent were white, nightmares had a black aura and… The other kind of dreams had pink… She tried to avoid them. However one particular door caught Luna’s eye first over the black aura ones. This door was deep purple but lacked any form of cutie mark yet it was clearly an adult’s dream (she had a sense for those things, Luna) and it was also radiating a deep blue aura. Intrigued Luna pushed open the door and stepped inside.

Twilight, with her notes finished and the sun just setting, knew Luna would soon be going to bed. Curling up within the room she had been writing her notes on the lamia experiments in, Twilight managed to mentally force herself asleep whilst laying against her tail to ensure she kept that form. When Twilight became aware of a floor she opened her eyes. Twilight had always been good at controlling her dreams and it was currently laid out like a blank white room. With a little bit of willpower, Twilight began to make tree’s grow out of the ground, grass curled up from soil as it appeared and the roof turned to a moonless night sky. Perfect, now all she had to do was focus mentally on Luna appearing, and a little touch of magic. Hopefully the Princess would be too curious to shy away from this.

Luna looked around at the giant forest before her, it was odd. It appeared to be a normal stretch of forest, brightly lit by the stars, but no screaming… This seemed like a peaceful dream or possible even a normal forest in the waking world. Yet somepony was obviously dreaming and the odd aura... Luna had to get to the bottom of this. Deciding she’d find more once she stepped in, Luna pushed the door open a little more and closed it silently behind her, however her appearance had already been noticed.

Twilight glanced over at a sudden new light, there, sitting in thin air, was a bright plain purple door with Luna standing within it. Twilight watched praying and sure enough the Princess stepped within the dream, closing the door. Twilight grinned rubbing her hooves

“Let the testing begin.” She thought. Twilight began to stretch her tail across the tree’s she had made, which were purposely dense at parts so she could pass unseen, though her snake belly helped blend in with the sky a bit if Luna glanced up. Finally Luna stopped almost directly below Twilight, for a second she feared the Princess had heard her, then noticed Luna’s horn glowing. She was about to leave! Abandoning everything Twilight made her move, sliding down the side of the tree into view

“Hello Princess.” Twilight said, stretching the s’ with her forked tongue.

Luna had wandered through the forest for several minutes, but had seen no form of pony within the forest, deciding that there was little she needed to do in this dream she prepared to leave, concentrating her magic to make the door out appear. Then a familiar voice spoke behind her

“Hello Princess.” Luna spun around then backed up. Twilight was hanging from the branches above from a snake tail that Luna knew she didn’t normally possess

“Twilight?” She whispered.

Luna looked a little nervous but Twilight decided to play the, I’m just dreaming card, and hoped that Luna would buy it and play along

“Yes, it’s me Luna, have you come to visit me?” Twilight lowered herself onto the ground and allowed her tail to slowly trail down from the canopy above. Then she began to circle the nervous Princess, grinning slightly.

Luna sighed a breath of relief, Twilight appeared to think she was simply a figment of her imagination. Though how she had taken on the form of a lamia was a curiosity to Luna, then again Twilight was a serious reader, she could have simply just found a picture of one, it was a possibility. Twilight began to circle the Princess who once again became nervous, she hoped the door hadn’t somehow messed up and turned blue when it had been a pink dream, but as Twilight spoke it seemed it had.

“I’ve been waiting for far too long for you to appear Princess,” Twilight whispered as a small wall of coils boxed Luna in “I’ve been very cold without somepony to… Hug. Mind helping me?” Luna backed up a little and opened her mouth but Twilight’s tail whipped forward from behind her and Luna fell down onto her rump, right onto a pile of coils. Before she could struggle free, several coils had jumped up like odd waving plants and held Luna still, a single coil slid under Luna’s chin and tilted her head up, to look at Twilight

“Now, let me have a good look at you.” Twilight whispered grinning as her eyes changed.

Luna attempted to look away but she had been distracted by falling, as Twilight had planned. The purple mare’s eyes were no longer their slitted purple, now miss-match multi-coloured rings were pulsing rapidly over Twilight’s eyes, drawing in Luna’s gaze. Luna’s jaw dropped as her pupils contracted and two lazily moving colours pulsed over her eyes, as her white pupils disappeared behind the colours Luna shivered as her body experienced a wave of relaxant based pleasure, she couldn’t look away from the colours now and the spirals would get faster and more frequent in her eyes. Twilight grinned at the slack jawed Princess and began to move her head about, piling her tail over the alicorn lazily, she had never figured out how to do the fancy coiling with her tail tip first properly.

As Twilight’s tail engulfed more and more of Luna her mind was slowly pushed away, her eyes became slightly lidded and her head tilted down, her chin touching her neck in open awe. Luna’s eyes twitched as part of her continued to resist but she was quickly losing the fight. Twilight glanced up and down the Princess’s body and steeled her nerves, now or never. Luna, unable to move her eyes from Twilight’s and with her vision blurring into swirling colours copying Twilight’s, didn’t see the end of Twilight’s tail sneaking towards the base of her body. However when it gently touched between her legs, her left eye twitched and she closed her mouth biting her lip and grunting in pleasure

“Nnooo, it’s one of those dreams! Luna thought desperately as more of her mind was wrapped within Twilight’s beautiful eyes.

Twilight gently ran her tail tip along Luna’s vagina, the Princess making sounds unfit for her to make in public. She was clearly enjoying it against her will, shivering and biting her lip, the rings in her eyes going lightning quick after every rub before slowing down, only to speed up again. Luna wouldn’t be able to withstand much more of Twilight’s mental barrage. Twilight leaned forward and began to whisper to Luna, her eyes so close there would be little more in her sightline

“Isn’t it just amazing? My eyes, slowly washing away your worries, your pain, your anguish… All of it just… Gone. And my tail, slowly pressing up against you, making you shiver in delight as your body builds up. It’s becoming so much, your head it ringing, your hooves are shaking in anticipation and you can feel the release, but it’s being snatched away, isn’t it.” Twilight turned the tail tip so that it was facing Luna’s vagina and began to pull on the edges occasionally prodding it, Luna’s mouth closed as she attempted to hold in the building orgasm that wouldn’t release because of Twilight’s orders “You can’t cum whilst you mind is still rebelling. You need to let your Mistress teach you your place. As my cute little slave, who loves nothing more than to be coiled up, hypnotised and ppplllaaayyyeeed with.” Twilight said dragging out the word with a stronger prod into Luna’s vagina “Let your Mistress take control of your mind, submit to the pleasure and cum, let me teach you where your mind’s place is… Within my power.” Twilight plunged her tail tip into Luna and the Princess surrendered, her head tilting back and her tongue rolled out as she orgasmed over the mare’s scaly tail “Good girl.” Twilight whispered as Luna’s mouth stretched into a smile.

Twilight flexed her tail lifting Luna up and smiled, making a mental note of Luna’s submission. She appeared to be under a deeper spell than the others she’d tested on, interesting. And she was also nuzzling Twilight’s tail which she found incredibly comforting, Twilight was also pleased to find Luna was much warmer than her cold blooded body, and could imagine it would have had an actual effect if this were the waking world rather than a dream. Twilight tilted her head, debating what she wanted to do next… Perhaps she could trigger pleasure by something but what. Twilight flexed her tail and Luna gasped, she continued to do that until the obvious idea popped in

“That feels nice, doesn’t it?” Twilight cooed as she tightened her tail around Luna, the hypnotised Princess nodded, her mouth open in a wide smile as her ‘Mistress’ toyed with her body “In fact, it’s so good, every time I do it you feel a wave of pleasure, right her.” Twilight ran her hoof along Luna’s still damp vagina and the Princess shuddered, her eyes rolling up a little “Do you want me to squeeze you more?” Luna nodded furiously.

Twilight smiled as her whole tail contracted around Luna, she gasped as her mind was buffeted by waves of pleasure that she had never felt before, mental pleasure… It was amazing. Twilight didn’t loosen her tail, in fact she squeezed a little harder. Luna gasped, her breathing a little difficult now, but the pleasure so much stronger. Twilight kept tightening her tail, Luna’s face slowly began to flush as she got less and less air, but the pleasure got higher and higher. Finally, when Luna was gasping and choking for air, she orgasmed within her tight prison and Twilight relaxed her tail, adding to pleasure from the relief of being able to breathe. Luna continued to breathe heavily as her pleasure high faded and her mouth closed, Twilight now wanted to try a few commands, so she slowly made her tail retreat from Luna and the Princess remained sat on the ground.

“Okay something basic, I think.” Twilight thought “Stand up.” Luna stood up immediately but Twilight shook her head. Anypony might want to stand up she had to do something Luna wouldn’t ever normally do “Stand on your hind legs and whimper like a puppy.” Luna complied and Twilight’s mouth twitched up into a small smile “Okay good.” Though not really, this was just plain old fake hypnosis ponies normally use at shows… Twilight decided to try to make Luna’s body do something it wouldn’t normally even be able to do on command

“Cum, right now, cum.” Luna’s eyes widened then she fell backwards, her rear legs flailing as she orgasmed onto the grass “Cum, again.” Luna’s moans became louder and higher and Twilight, for some reason fascinated by what she was making Luna do, kept repeating the order for Luna to cum. Twilight leaned down pinning Luna’s rear hooves still with her tail and positioned her mouth in front of Luna’s vagina, licking and swallowing her juices, moaning herself and reaching down to stroke a part of her tail that was feeling incredibly hot.

Twilight grabbed Luna around her waist with her tail and rolled over herself. Luna was panting heavily, drenched in her own love juices

“L-lick me, slave!” Twilight ordered, not even bothering to sound commanding as her own needs began to dominate her mind. Luna pushed down the scales around the top where they joined to Twilight’s pony body and her vagina was revealed, as if she knew where she needed to pleasure, and began to lick as if it were a tasty ice cream. Twilight moaned falling onto her back and letting her hooves flop down either side of her. This was bliss, Luna, the Princess of the night, pleasuring her, sticking her tongue within Twilight. It was so hot, so intoxicating, so good

“I have to… try this on Fluttershy… Rarity… Applejack- ALL OF THEM!” Twilight screamed as she orgasmed over Luna’s face, her slave smiling as she completed her work. Twilight brought her tail around and gently stroked Luna’s tail before pushing it aside

“You have such a soft plot, Princess.” Twilight whispered as she forced her tail inside Luna’s plot without her knowing. Twilight let her eyes spiral and Luna buried her mouth in Twilight’s vagina again, muffled cries escaping her as her pulsing eyes shook from all the pleasure. Luna reared her head back and began to cry out as she orgasmed

“Again, cum again Luna, all over my tail!” Twilight ordered grinning evilly, positioning a thick coil between Luna’s rear legs and Luna was forced to obey. Twilight, fuelled on by lust, continued to repeat the order, Luna’s screaming become more and more shrill.

Finally, as Luna’s voice began to reach the pitch only bats would hear, Luna gave an odd shudder then simply disappeared. There was no sound, no warning, she didn’t fade, she was there one second, gone the next. Twilight’s jaw dropped and she realised the Princess had finally awoken from too much stimulus. Panicking Twilight slapped herself awake and sat up in her room. Twilight gulped and began writing down notes, all the while her brain thinking up any form of excuse she could use if Luna ever visited her again, in the flesh or in her dreams.

Luna’s eyes snapped open and she groaned, for a brief second her eyes had still been pulsing like in Twilight’s dream then they returned to normal. Twilight sure could be very kinky when she wanted to. Luna lay back then felt a stickiness. No surely not… Luna pulled the covers up and felt her face flush as she pulled the damp, orgasm drenched covers close. Jumping up from her bed and locking the door in a flash of magic Luna glanced around, then flipped the covers off and over and began to clean the mess, but all the while her mind was racing. That had all felt so good… The hypnosis, Twilight’s tail, her commands and of course all the orgasms. Luna began debating if she could find some way to repeat it when the wonder popped into her mind; what did it feel like to be the one in control? A small grin stretched across Luna’s mouth as a dirty idea formed… She’d have to wait until tomorrow however and see if she couldn’t find a pony sleeping with a particular fetish so she wouldn’t be discovered by the public. The following night was going to be fun.
