Twilight hangs out with Rarity (vote chapter)

Whilst Starlight was freely fucking Spike, Twilight had taken the opportunity to visit her friend and Mistress Rarity. As she flew towards the Boutique she took the opportunity to pass by the bathroom window. To her delight, she could hear the erotic moans of her Mistress, with the steamy shower running. Landing on the roof, just out of the sight of the window, where she could take a sinful peek, and hear her sweet moans. Twilight opted to snake her hand into her pussy right there and masturbate to the musical sounds of Sweetie Belle and her Mistress Rarity's screams. If anypony looked up they'd find quite the scandalous sight of the Princess of Friendship publicly pleasuring herself to her best friend. But none did.

“Yes, Sweetie Belle keep it up. Keep kneading your sister’s beautiful breasts. Keep fingering my pussy. Keep it up.” Rarity groaned in orgasmic delight inside. The sweet and sexy Sweetie Belle was eager to fulfil her sister's wishes. Unfortunately for Twilight, it seemed that she had only caught the ending of their little tryst, as Rarity was soon brought to delightful screams of ecstasy by her younger sister. Leaving Twilight alone and frustrated.

"Oh come on." She growled to herself as she heard Rarity and Sweetie Belle turned off the shower. No more moans of ecstasy for Twilight to masturbate to. "I should have been here sooner."

With great disappointment, Twilight was **** to leave her perch on the top of the Boutique and fly down to the entrance. She did so as fast as possible, hoping to catch the two in the illicit affair. Pulling her skirt back down to maintain some illusion of modesty she knocked on Rarity’s door.

She could hear the crash inside, and the erupting maelstrom of panic from inside. “Rarity it’s me Twilight. I’m coming in.”

Rarity gave all her friends keys to her house, she never liked keeping them out if she wasn’t home. The unspoken rule of course was that if she was home they were supposed to knock and wait. But unspoken rules weren’t so much rules as guidelines that Twilight opted to not follow for the moment.

She entered and she could hear Rarity’s panicked screams from up in her room. “Just a minute Twilight. Please don’t come in.”

“Is something wrong Rarity? Do you need help?” Twilight asked cheekily. She knew she shouldn’t do this, but Rarity hadn’t agreed to be her Mistress yet. She could do this as much as she wanted. "Applebloom was looking for Sweetie Belle. Is she here?"

"NO!" Rarity shouted, her voice in complete panic from her room. Twilight could hear something crash, perhaps in a panic she had crashed into something or tipped it over. "Twilight I'm not decent."

"Oh, then I'll just wait here then. Do you know where Sweetie Belle is then?" Twilight called up, earning another gasp from upstairs.

"No Twilight I don't. Please, please wait downstairs." Rarity begged from inside her room. And Twilight decided she’d had enough. Though if she listened hard enough she could hear her faint whisper. “Stay in the cupboard Sweetie and no matter what don’t come out.”

“Alright, Rarity take your time," Twilight called out before taking a seat. She was waiting for some time as Rarity busied herself trying to look halfway presentable, and even when Rarity met Twilight she was only halfway.

"Twilight please allow me to let you in rather than barge inside. It's okay if I'm not around but I think it's simply polite when I'm here to wait until I answer the door," Rarity said with the slightest hint of anger in her voice.

Twilight however saw another opportunity by feigning concern. “I’m sorry I was concerned I thought I heard you and Sweetie Belle screaming.”

Rarity’s face was a deep scarlet, had she been holding something she almost certainly would have dropped it. “I haven’t the faintest idea what you’re talking about Twilight.”

“I suppose I might have misheard things. Anyway, I popped in when I was passing by Rarity and I wanted to check up on you.” She explained to her.

“Oh by all means Twilight, let me put on some tea.” Rarity replied, her voice sounding somewhat ****. As if she was trying to think of exactly what she should be saying so the situation sounds normal. She rushed over to the kitchen to prepare said aforementioned tea.

“Rarity I’ve been thinking I know we share all the details of each other’s fantasies but I was thinking why stop there? We should share all the juicy perverse facts of our sex lives, I think that will bring us much closer.” Twilight explained clapping her hands together in faux innocence, as she used her power as Princess of Friendship to twist the boundaries of their friendship to something much more personal than Rarity was expecting.

For a brief moment, Twilight could see Rarity’s eyes freeze with shock and panic before her magic took over and Rarity’s whole body relaxed. “I think that’s a wonderful idea Twilight. Shall I go first?”

Twilight smirked at the change of attitude and lay back in her chair in satisfied delight. Rarity returned to the table with two cups of tea in each hand, handing one to Twilight and taking a seat opposite her.

“Go ahead,” Twilight offered before taking a sip.

Rarity sucked in a deep breath. “It was a few days ago when Sweetie Belle and I first did the sinful deed. Since then whenever I shower she comes to please me, almost on command. It’s a little game she likes to play you see every time I should shower, she plays the role of a servant so perfectly. Calling me Mistress, and acting as a servant.”

She explained all this now without a hint of shame, but rather with the sort of embarrassment two girls at a sleepover shared over their crushes.

“Your own sister?” Twilight asked in mock shock, receiving a guilty giggle.

“Yes, well the forbidden nature of it just adds spice to the relationship. And just between you and me, Sweetie Belle loves it when you slap her on the ass.” Rarity whispered, before giggling. Twilight maintained a smile that did not betray her foreknowledge. “What about you darling? Any trysts I should know about?”

Twilight smirked at her friend, twirling a strand of hair in anticipation. “I might have.”

Rarity’s smile was predatory. “Now Twilight I told you, you must tell me.”

“I might be involved in a certain harem,” Twilight explained causing Rarity to gasp in delight.

“Oh, my dear you must tell me everything.” She demanded firmly, a delightful hint of arousal in her voice. Putting down her plate and clasping her hands in anticipation. "I should have known you couldn't be satisfied with just one stallion, so who are they? Or is it, not a stallion but a group of lovely mares?"

Twilight's smile became sly. "Rarity I'm not the Mistress of this harem, I'm one of the servants."

Rarity's face burned a scarlet red as Twilight's sex life turned a bit too similar to her own fantasies. "But you're a Princess Twilight, you can have anypony and a harem of them."

Rarity's teeth bit down on her lips in fascination, whilst Twilight stretched out letting her quite skimpy outfit strain against her body. "But I don't want to have a harem, I want to be a sex ****. Just like Cadence."

"Cadence? She's part of this harem too?" Rarity asked, trying and failing to keep her fascination out of her voice. Twilight nodded smiling with barely contained glee. Her arousal now caused her nipples to begin poking through the vast cleavage of her outfit.

"And Starlight too," Twilight added. Rarity's eyes looked as if she was peering at solid gold, as she leaned ever so closely forward.

"Tell me darling who is the lucky stallion?" Rarity demanded, with almost a hunger to know the truth.

"Well..." Twilight explained, her voice husky and low as if sharing a forbidden secret. "The trouble is he's **** about our harem. Despite our wish for him to fuck the ever-loving shit out of us like the bitches we are he's still ****. He's too noble for his own good."

"Is it by any chance Shining Armor? Seeing as Cadence is involved, it seems you and I might have more in common than I thought Twilight." Rarity asked, her hands now gripping her lap as she listened with perverse interest.

"It's Spike actually," Twilight answered and in an instant Rarity's face went as pale as a sheet.

"You're... with... Spike..." Rarity stammered, her throat spitting out the words as if she was being choked. "You want to be his sex slaves in a harem?"

Rarity was torn between several emotions, relief, fear, embarrassment, concern and interest all warred before her. "You've had sex with MY Spikey Wikey?"

Twilight had to admit that she felt her skin pale in fear at her reaction. "Well um, kind of."

Rarity's face seemed to flip between many different emotions. Betrayal, interest, fascination, arousal, hope and shame flashed in equal measure. "How... um, how was it?"

"Unbelievable he was able to satisfy Cadence. No pony can satisfy Cadence." Twilight explained to Rarity much to her fascination. "He took both me and her at the same time. He was strong, unbelievably strong and big filling us completely. And he has two dicks, one that retracts so he can satisfy more than one of us at once. But he's so humble, too shy and noble to treat us like the bitches we are.”

“Twilight please-“ Rarity gasped, and Twilight struggled to read the expression on her face. Could be arousal, could be heartbreak, could be any number of things.

Meanwhile back at the Castle of Friendship Spike, having sent Starlight on his way decided to do what he should have done when he first got the power. He picked up a quill and scroll and wrote:

Dear Princess Celestia

A/N: No Celestia isn’t joining the harem any time soon, this is just set up. She will join eventually I promise. Speaking of which the race is neck and neck between finding the other roots and Fluttershy. With 52 to 51 votes respectively, followed by Rainbow Dash at 45 votes. Since the race is so close, and given the nature of the vote and choices I think I may just combine the two.

Sorry, this took so long I meant to have it up yesterday. The straw poll is here: https://strawpoll.com/polls/1MnwvKDWdy7/results
