Changes came for good

My Dear Teacher

Sunset Shimmer had been back in Equestria for years now, and couldn’t be more happy. Her new home was a castle — not her own castle, but the castle of her princess, Twilight Sparkle. This stupid, adorable idiot had come into her life some years earlier. Of course, Sunset had never expected this — to date her, to live with her, and to wake up with her every day — but by some strange twist of fate, Sunset was home, a pony again, and dating the Princess of Friendship.

The irony was that Twilight was the very same mare, or person, who had crushed Sunset, taking her demonic powers at the Fall Formal. But Sunset no longer had a problem with that.

Sunset began to fall in love with Twilight the second time the princess had visited Canterlot High. Twilight was so good for her, that thirty moons later Sunset decided to use the portal to return to Equestria.

Princess Celestia and Sunset soon reconciled, and Celestia often came to visit Sunset and Twilight in the castle socially. A few months after Sunset’s return and after a few friendly dates, Sunset finally told Twilight how she felt about her.

Since then life couldn't have been better. She lived in a castle, had friends, and had a mare she loved more than anything. But after three years, Sunset started to yearn for something different — something exciting. Things had begun to get a little monotonous in bed. Twilight still had the best flank she had ever seen, and sex with her was wonderful, but she needed something new for once.

Years ago, Twilight had lead a sheltered life in Canterlot. She’d had no social life, and she’d liked it that way. But coming to live in Ponyville, in retrospect the best decision she’d made in her life, even if Princess Celestia had needed to push her towards it, had forced her to change. Now she had plenty of friends, and had become pretty good at understanding what her friends wanted — what they needed — even when they couldn’t or wouldn’t express themselves in words.

So Twilight couldn’t fail to notice Sunset’s wistful sighs as they lay in bed after making love. She knew that Sunset was getting bored of the same old routine every night, or to be more honest, the same old routine every third or fourth night.

After spending a few days asking herself what she should do for her marefriend, Twilight finally decided how to spice up their relationship. She was going to need her glasses, and some clothing from Rarity.

Then she would just need to put her plan into action.

“So, darling, you’re planning a surprise for her?” Rarity asked while looking for a white shirt that she was sure was hiding somewhere.

Twilight blushed. “Er… yes, she needs a change, so I’m going to make it happen.” She didn’t like to talk about this sort of thing, not even with her friends. “I just want to make her as happy as she makes me.”

“That’s wonderful, dear. I hope I find my Prince Charming like you did… or Princess Charming… or whatever…” Rarity finally spotted the shirt, and lifted it up with her magic. “Oh!” She held it up in front of Twilight to get a rough idea of how well it would fit. “Here! It fits you perfectly! It has these little fastenings. It should be easy to take off — or rip off, if that turns out to be necessary.” Rarity gave a sly smile to Twilight, who smiled back nervously, biting her lip and flicking her tail.

Twilight took the white shirt. “Yes, this will be perfect. Thank you, Rarity, I don’t have anything like this.”

“No problem, darling, that’s what friends are for! Now go and blow that mare’s mind,” Rarity said. She showed Twilight to the door. “And I want to hear everything about it tomorrow at the spa!”

“Rarity, I’m not going to tell you that.” Twilight looked at Rarity who was putting on her most disappointed pout. “Okay, I’ll tell you… but only you, and just because you helped me!” The princess gave her a smile. “Bye, Rarity!”

“Go hunt your prey, tigress!”

Later that day…

Twilight heard the loud bang of the huge castle doors closing. Everything was ready, and she positioned herself carefully on the bed, with her flank facing directly towards the door. She propped a book in front of herself so that everything looked normal, and peeked back out of the corner of her eye, waiting for somepony to open the door.

“Hey Sparky, where’s Spike?” Sunset asked, opening the bedroom door. “Spar… ky…?” Sunset’s eyes widened seeing Twilight in that position, dressed up and wearing her favorite glasses, for apparently no reason. “Umm… what are you doing?” Sunset’s eyes were fixed on Twilight’s flank and her marehood, swollen and aroused for some reason.

Twilight closed her book. “You’re late, Sunset Shimmer.” She climbed down from the bed, walked over to Sunset’s side, and bit her ear. Sunset’s eyes popped open again and she grinned and bit her lower lip. Twilight was never usually like this, but Sunset knew that she liked it. “You know what teachers make late students do?”

“Teachers?” Sunset looked at Twilight and then understood. “Oh boy…”

“A teacher punishes her student, Sunny. That’s what she does. And I’m your teacher, Sunset.” Twilight rubbed her head against Sunset’s neck and then looked longingly into her eyes. “And you have been a very bad student, don’t you think?”

Sunset realised that Twilight must have picked up on her frustration. “Y-yes, I have.” A little smirk crept onto Sunset’s face.

Twilight noticed Sunset’s smile and put on her most serious expression. “You find tardiness amusing, Sunset?!”

Sunset played along. “N-no…”

“No, Miss Sparkle,” Twilight corrected her.

“No, Miss Sparkle.”

Twilight was now standing behind Sunset, so Sunset had to look over her shoulder to maintain eye contact. “Tardiness is a very serious matter, and tardy students need to be punished.” Twilight pushed Sunset gently from behind, causing her to stumble and land on the bed. Sunset watched as Twilight climbed on top of her. Sunset closed her eyes, waiting for the inevitable kiss, but instead she felt something tie her hooves and cover her mouth.

“What?” Sunset tried to ask, her eyes shooting open.

“Be a good girl, Sunset, and next time we do this, you will have your turn,” Twilight smiled at Sunset’s confusion. “Today, Sunset, I’ll do everything I want with you. To begin… well, where to begin? What could I do with you? Maybe I could try…” Twilight climbed up her marefriend to reach her horn, making sure that her already wet marehood was pressed against Sunset’s belly as she lay on top of her.

She gently licked the very tip of the horn, and Sunset had a small spasm. Twilight smiled at the taste, which reminded her of the shampoo Sunset often used. She parted her lips and pulled the whole horn into her mouth. The blunt, rigid tip was immediately assaulted by Twilight’s tongue as she swirled it around the spiral shape.

She increased her speed, her head bobbing up and down on her lover’s length. Sunset's horn was feeling warmer, and she moaned against her gag. Twilight held the horn gently between her teeth, making Sunset shiver and moan even more.

Twilight kept sucking her lover’s horn until she finally felt Sunset’s body arch, and the mare moaned in pleasure. Twilight smiled, and took the horn out of her mouth. The horn shone brightly, illuminating the entire room. “I don’t think we’re through yet.” She removed the gag with her magic, and kissed Sunset on the lips.

Twilight kissed her lightly, but Sunset responded with passion. Their tongues fought a small battle, with Sunset the clear winner. Sunset felt freer without the gag, and leaned in to kiss the neck of her "teacher", alternating between gentle kisses and love bites. She paused for a moment, taking in the scent of her lover, but then her eyes widened when she felt Twilight beginning to grind against her.

Twilight bit her lip. “Time for round two!” Twilight’s horn shone, and a big strap-on appeared. Sunset moaned just seeing it. Twilight rubbed her head against Sunset’s chest while she strapped the toy around her hips. “Are you ready, my dear student?” she asked, lining the toy up with her lover’s wet entrance.

She had second thoughts, and instead took a moment to kiss her way down Sunset’s chest and belly, rubbing her hoof between her lover’s thighs. When her mouth reached Sunset’s marehood, she slowly circled her tongue along the outer rim of the entrance. Twilight had only done this once before, Sunset usually taking the more active role in their love making. But she still remembered that wonderful taste, completely unlike anything else in the world. She loved that. Her tongue slowly explored the slick cavern, testing the space inside, and checking how tight the hole was. It was a tight marehood. She slowly slid her tongue in and out of the tight walls that seemed to be hugging her tongue.

Sunset let out a moan, watching her marefriend licking her. Twilight swirled her tongue in a circular pattern and pressed her nose against her lover's clit, rubbing it while eating her lover's treat with vigor. She slipped her tongue deep inside, moving it erratically, and totally lost in the delight of the activity. Sunset squirmed in delight.

Sunset closed her eyes as her body locked up again. “Oh… Twilight… I’m going to…” Sunset didn’t have time to finish before she came in Twilight's mouth. Twilight savored her lover’s juices. Sunset moaned one last time, and looked at Twilight who was again positioning her hips at Sunset’s entrance.

Twilight slid the toy’s tip into Sunset with a weak thrust, making her groan. “Twilight… please, I want it fast… hard and fast!” Sunset moaned as she closed her eyes and bit her lip as she felt Twilight reach the limit of the strap-on’s length.

“Well, you’re doing a good job, and being a good girl, Sunny, so I suppose you deserve a reward.” Twilight winked at her before leaning over and kissing her marefriend on the lips. This change in position shifted the toy inside Sunset, eliciting another groan of pleasure.

Twilight began to thrust quickly and deeply, and a slick wet sound rang out across the room. Sunset felt like she was in heaven. She lost all control over what came out of her mouth, alternating between swearing and loud moans. Sunset had ridden Twilight with one of these toys many times before, but she had never experienced it this way around.

The pleasure of hearing Sunset call her name, combined with the pressure the strap-on was providing against her own marehood, brought Twilight towards her own limit, and she was soon moaning as much as her marefriend.

“Twilight, I…”

“Me too…” she moaned and thrust one last time. Twilight pulled out, leaving only the tip of the toy inside her lover. Sunset looked at Twilight in confusion. Twilight took a deep breath, basking in the glorious sight of her lover beneath her.

“What are you--” Twilight put all her weight into one last hard thrust, bringing Sunset to another powerful orgasm. “Twilight!” she screamed the princess name with a roar as loud as a wild Manticore. Twilight climaxed at the same time, moaning her mare’s name.

Out of breath, Twilight rolled off her lover’s body, the toy slipping out of her slick passage. She lay at Sunset’s side, panting like a dog in a hot Summer day.

Twilight made the strap-on disappear with her magic, and rested her head on Sunset’s chest. She smiled at her mare. “Did you like our… little change?”

“It was… wonderful…” Sunset smiled. “I didn't know you were so good at being the top. I think we need to try this again some time.” Sunset laughed. “I love you, Twilight.”

“I love you too, Sunny.” They kissed one last time before falling asleep, exhausted.

It’s good to try something new from time to time. Especially something new like that.
