Diamond entered her room and closed the door a little rough, making Emerald, who was standing in the small kitchen area, jump with surprise.

"Oh... Diamond..." she said. "What's wrong?"

"Nothing, I... I just saw Twilight... doing it with Trixie..." she said, sitting on the couch.

Emerald tilted her head, even more confused. "You saw two mares doing it? I guess that would be... surprising?"

"It's not just that..." the older sister said suddenly. "They aren't even dating. In fact, they both have a marefriend of their own..."

This got Emerald curious as the younger sister came over and sat beside her. "So, they were cheating and you feel like you should tell the others?"

Diamond shook her head. "No... All four of them... They know... Trixie and Lightning sometimes go to Twilight for some fun when they're feeling... submissive..."

Emerald went wide-eyed. "So, Twilight's... like a mistress?"

"She is a mistress... She has a room with three other mares..." Diamond said, sweat running down her body. "And, the weird part is... they all like it... Those three mares are choosing to be with Twilight... And, Midnight, Twi's marefriend... is a part of it, too... She even helps... take care of the girls..."

"Wow..." Emerald said with a blush. "So, there's, like, a sex dungeon right down the hall from us?" Diamond nodded. "Well, I suppose that's a good reason to be weirded out by it..."

"I'm not weirded out..." the older sister admitted. "I just feel bad for accusing her of raping Trixie... Truthfully..." she said, rubbing her arm. "I-I'm sort of... curious..."

"Curious?" Asked Emerald. "Come on, sis. You can't be thinking of going to Twilight to be... dominated... right?"

"E-Everyone else loves it!" Diamond all but shouted, standing up and chuckling crazily. "It must be good, right? Wh-Why else would three-- n-no... s-seven mares love it?"

"W-Wait... Seven?" Asked Emerald, becoming confused again.

"Rainbow Dash and two mares at the city's sex toy shop..." Diamond said, covering her face. "So tempting to just go down the hall and ask..."

Emerald watched her sister deal with her conflicting emotions before standing up. "Then, go. It's the only way for you to be sure that you like that sort of thing... I mean... the others trust her, right? So, she must be gentle..."

The older sister spread her fingers, eyeing her sister before sighing. "Alright..."

Twilight sat down on her couch with a sigh. "Ohhhhh..."

"What happened?" Asked Midnight, leaving the bedroom wearing only her underwear, adjusting her bra as if she had just been doing something naughty.

The purple mare eyed her. "Know those new girls I brought in?"

"Yeah?" The black mare said questioningly as she sat down beside the unicorn. "What about them?"

"The older one, Diamond... She saw me fucking Trixie against a wall so we had to explain everything..."

"How'd she take it?"

"She seemed a little... weirded out? I just hope she understands..." Twi said, before smiling and leaning against the black mare. "that I love my Midnight."

The mare chuckled and nuzzled Twilight's head. "And I love my Twilight..."

Twi then noticed the mare was in her underwear. "What were you doing in there?" She asked.

"Relaxing," the black mare replied and smiled.

"Relaxing?" The purple mare asked, raising an eyebrow. "How?"

Midnight smirked as Aqua emerged rom the bedroom, leash in hand with the collar attached to Cauliflower. The white mare crawled out on all fours, looking rather exhausted.

Twilight sat up and let out a chuckle. "Bring her over," she said, motioning to Aqua.

The blue mare nodded and began walking the white mare over to her mistress, Collie crawling beside her with a blush on her face as she looked up at Twilight. The two made their way around the couch and in front of the purple mare.

"Learned your lesson yet?" Twi asked the white mare with a smile.

Cauliflower whimpered and nodded. "Yes, mistress..."

The unicorn smiled wider at that and looked at Aqua. "You may remove the collar..." The blue mare nodded and removed the dog collar, carrying it into the bedroom as Twilight smiled at Collie. "Now let's reward you, shall we?" She asked, pulling her pants down and letting her meaty shaft spring free.

Cauliflower hesitated for only a second before leaning in and placing kisses all over the unicorn's love pole. Twilight smiled and patted her head. "Good girl..." she cooed as Midnight slid to the far end of the couch.

The black mare then reached her hand inside her panties and began to finger herself as she watched. After about another minute or so, there was a knock on the door. Twilight eyed Midnight before looking at the door.

"Who is it?" The purple mare asked, letting Collie continue with her kisses, which soon turned to licks.

"I-It's, uh... Diamond..." came a nervous-sounding voice.

Twilight went wide-eyed and looked down at Collie and then at Midnight. "U-Uh... Hold on a minute," she said, about to tell Collie to stop before the mare on the other side of the door spoke up.

"I-If you're, um... doing that then... y-you don't have to stop..."

Twilight eyed Midnight, who simply shrugged, still fingering herself as Twilight looked at the door again. "Alright, then... Come in..."

There was a brief moment of silence before the door opened and Diamond stepped in. Twi had to use her magic to make the door close as Diamond was too nervous to remember to do so. The mare then stood there awkwardly, not saying a word.

"So..." Twi started as Diamond's eyes went to Collie and Twi's cock. "Why, uh... Why are you here, Diamond?" She asked, watching the mare's face to see her reaction to all this. "Not that you aren't welcome... But... why'd you--"

"I-I wanna learn," Diamond squeaked out, eyeing Collie before seeing Aqua at the back of the room talking casually with another, slightly lighter shade of blue, mare.

"Learn?" Asked Twilight, sounding confused. "Learn what exactly?"

"N-Not learn, uh... Understand," Diamond corrected. "Why do these girls... uh... W-Well..."

Twi tilted her head in thought before smiling. "You wanna know why they trust me and why we do what we do the way we do it?"

Diamond nodded. "Mm-hmm..."

The unicorn smiled and patted her chest. "Up, Collie," she said, as the white mare stopped her cock licking and climbed into Twi's lap, facing her. "Well, I suppose the fact I saved all of them from the street helped... I then gave them a choice... and they wanted to be with me."

Diamond eyed Aqua at the back. "That true?" She asked, getting the blue mare's attention. "You had a choice?"

Aqua smiled at her. "I was a thief..." she said, walking closer. "Stole from anyone in order to survive... Couple stallions I was with, and me, stole from a friend of Twilight's. He killed the stallions I was with, but... Twilight spared me and took me in..." she explained, standing behind the couch and smiling down at the purple unicorn.

Twilight smiled back at her. "My first one..."

Aqua reached out and gently rubbed the unicorn's shoulders. "You wanna know why we stick with Twilight?" She asked, looking at Diamond. "She isn't rough and abusive like you'd expect most mistress' to be... She cares about us and is very gentle... And, the sex feels sooooooooo gooooood..." she said, practically moaning the last part.

Diamond blushed hard before watching the white mare in Twilight's lap begin to place kisses on her mistress' neck. "W-Well, uh... Um... C-Could you... maybe... sh-show me?" She asked nervously, visibly avoiding eye contact with anyone.

Twilight hesitated before smiling, leaning in close to Collie's ear. "On the couch," she whispered.

The white mare nodded and rolled off the mare's lap, sitting beside her. Diamond eyed Twilight's dick as the mare got up. Twi then pulled up her pants and moved towards Diamond.

"So...in order for me to show you..."Twi started, stepping up to the nervous mare. "I'll need full access... to your body... You know that, right?"

Diamond hesitated before nodding with a blush. "Y-Yeah..."

Twilight gave her a reassuring smile as she placed a hand on her cheek, rubbing gently. Diamond closed her eyes, feeling the soft hand of the mare against her cheek, feeling a tad bit more comfortable. If the mare was this gentle then this should be fun.

The purple mare then stepped right up to her so their chests pressed together, before leaning in a giving the mare a quick, brief kiss. Diamond went wide-eyed briefly before feeling the mare pull away. Twi then waited to see what the mare's reaction, watching her lick her lips.

Twilight smiled and leaned in, slowly moving her lips towards the mare's lips in order to give her chance to pull away. She did nothing. Their lips touched again and, this time, Twilight held it for a little longer before stopping. She didn't pull away, though. She kept her mouth inches from Diamond's, before feeling the nervous mare kiss back. Twi smiled and kissed back, the two going slowly as both closed their eyes.

Midnight watched them with a smile as she slipped her hand in her panties. As she did, Collie looked over at her. Smirking, Midnight pulled her panties down and patted her wet slit. Cauliflower smiled and crawled over to her.

Twilight slowly moved her hands to Diamond's hips, slowly moving them to her ass. The mare flinched only slightly before relaxing. as the kiss went on, Twilight moved her right hand up Diamond's body and towards her breasts. When her fingers grazed the mounds, the mare let out an "eep".

The unicorn quickly pulled her hand away as the broke the kiss.

"S-Sorry..." Diamond apologized. "I guess I'm still... a little uncomfortable with... someone else touching my body..."

Twilight nodded and smiled. "I understand... But, you... still want to know what it's like?" She asked, recieiving a conformational nod from Diamond. "Then, what if you got a shower started, got undressed and all... and then I come in? Would that work?" She asked gently. "It'd also be private..."

Diamond smiled and nodded. "Where's the, uh..."

Twi pointed at the bedroom. "In there."

The nervous purple mare smiled and quickly made her way into the bedroom. As she did, Azure watched her before looking at her mistress.

"You like seducing mares in shower?" She asked with a smile.

Twilight chuckled and turned around to face them. "What's hotter than a wet, sleek body?" She then spotted Collie with her face between the legs of a moaning Midnight. Smiling, she walked over to her and leaned in. "Enjoying yourself, babe?" She asked, gripping Midnight's breasts.

The black mare gasped and moaned, nodding. Twi chuckled and reached behind her, undoing her bra and pulling it off. "Aqua..." she began, before leaning in and giving each nipple a quick suck.

"Yes, mistress?" Asked the blue mare as she walked around the couch to stand beside her.

"Help Collie make my sexy girlfriend feel really good, huh?" She said, before standing up and patting the back mounds. "Start with these."

Aqua smiled widely and nodded, taking Twilight's place at Midnight's breasts as the purple unicorn headed into the bedroom.

Twi then waited until she heard the shower turn on. After waiting a tad longer to make sure the mare was inside, Twilight made her way to the door. Opening it and looking inside, she saw Diamond in the shower, right arm over her breasts and turned slightly so Twilight couldn't see between her legs. She didn't make any move to run and she didn't look threatened. Only nervous.

Twi gave her a reassuring smile as she pulled off her shirt. She then made her way to the counter and set her shirt down, back to the shower. Closing her eyes, she slipped out of her pants and set them on the counter with her shirt, humming to herself. Afterwards, she removed her bra and set it with the rest of her clothes. She didn't have any panties on as she currently had her futa cock.

Turning around, she half-expected Diamond to be gone... but, there she was; watching her undress. Smiling, the unicorn walked towards the shower and opened the door, climbing in. After shutting the door, she took a step towards the nervous mare and stopped.

"It's okay..." she cooed gently, smiling as she took another step closer. "Show me your body... I won't touch anything, I promise... You just need to get used to being exposed to me..."

Diamond nodded shakily, her arm twitching lightly before she slowly removed it from her chest. Twi watched as the mare's C-cups came into full view while their owner blushed heavily, not able to make eye contact with the unicorn.

Twi smiled and stepped up to her. "You have an amazing body..." she cooed. "But, that can wait... First, let's try kissing again, okay?"

Diamond eyed the mare before nodding. Slowly and gently, Twilight reached out her left hand and placed it on the mare's cheek. The darker purple mare shivered at the gentle touch before looking Twi in the eyes. A few seconds passed before the space between their lips disappeared, both closing their eyes and enjoying the moment.

After a minute or so had passed, Twilight stepped closer to the mare so their breasts squished together. Diamond let out a soft gasp but kept the kiss going. Then, to Twilight's surprise and joy, Diamond stepped closer until Twi's cock was sandwiched between the mares' stomachs. The darker purple mare shivered when she felt the hard shaft against her skin but made no attempt to stop.

The kiss went on for what seemed like an hour before Twilight slowly broke it. She then began trailing kisses down Diamond's neck, who kept her eyes closed and tilted her head back.

"Th-This feels... r-really good..." she said with a smile.

Twilight chuckled softly as she moved lower, needing to back up so she could reached the mare's chest. "Do you see why the others like me?" She asked, kissing the tops of the mare's breasts.

Diamond shuddered from the pleasure and nodded. "Oh, yeah..."

Smiling, Twi continued to kiss over the left breast before giving the nipple a few licks. As she gripped the right breast, she began sucking on the left nipple, making Diamond moan out. As she sucked, Twilight soon felt a hand on her cock and looked down. Diamond had reached out to feel it before pulling away.

"S-Sorry..." she apologized.

Twilight giggled and stood upright, letting her rod stick straight out. "No worries. Get a closer look if you want..."

Diamond hesitated before eyeing the throbbing meat pole, slowly getting to her knees with a blush. After eyeing the tool for a few seconds, she reached out and gently gripped it.

"W-Wow..." she said in awe. "So hard... and warm... And, it's throbbing..." She then looked up at Twilight. "Does it hurt... when it goes in?"

The unicorn smiled warmly at her. "Only at first and only for a little bit... Then, you're filled with pleasure..."

The kneeling mare nodded and gave the cock a stroke. "I know that... some mares... like to... um... s-suck on 'em?"

Twilight nodded. "Yeah... But, you don't ha--" She was cut off when Diamond leaned in and started licking the shaft. "O-Oh, wow... Getting into it, are we?"

Diamond nodded with a pant before slipping it into her mouth. Her blowjob was quite sloppy as it was her first time, however she didn't fail to pleasure the lighter purple mare. Twi let out moans and tilted her head back.

"Oh, Diamond, that's good... Sloppy... but, good..."

It didn't take long for Twilight to become horny as she gently grabbed Diamond's waist and helped her to her feet, her cock slipping out of the mare's mouth with a pop.

"Wh-What now?" Asked Diamond, looking a little upset to have been pulled away from Twi's dick.

"Next is the big thing..." the unicorn declared. "I penetrate you." Diamond gasped and blushed, covering her pussy. Twilight then smiled and leaned in, kissing her cheek. "Trust me... I'm gentle..."

The darker purple mare nodded and removed her hand. "O-Okay... I trust you..."

"Good..." cooed Twilight as she aligned her cock with her hand. "Get ready..."

Diamond bit her lip as she felt the rod poke her slit. After a bit of playful pushing and rubbing, Twi gently eased her way inside. Diamond gasped and let out a deep moan as she leaned forward, resting her head on Twi's shoulder.

"Relax..." the unicorn cooed as she pushed further in until their crotches met. "There... All the way in... How's it feel?"

"H-Hurts a little, but... I-I'm starting to feel... good..."

Twilight smiled and gently held the mare's hips. "Then, let's begin..."

She pulled out almost all the way before giving a gentle thrust back in, making Diamond moan out with pleasure.

"There it is..." she moaned, panting lightly as Twi gave another thrust. "Th-That feels good..."

"Told ya," Twilight whispered before doing a steady rhythm of light and gentle thrusts.

Diamond wrapped her arms around the mare and moaned, her sot fingers pressing against Twilights athletic back. Both mares continued to get rained on by shower water as Twilight let Diamond feel what sex was like for the first time.

As time passed, Diamond's moans increased as Twilight's speed picked up. After a bit longer, Twilight gave a couple hard thrusts before cumming deep inside the mare. At the same time, she felt a splash of orgasmic fluids from the mare and her own pussy.

"Wait!" Diamond gasped, panting heavily as she rested her head on Twilight's shoulder again. "W-Won't I get... pregnant now?"

Twilight gave a small giggle as she gently and lovingly held the mare. "No, silly... I have a magic cock. A spell that I was taught from one of our leaders... I can choose whether or not my orgasm is fertile..."

"Oh..." Diamond said, before letting out a breathy chuckle. "Good..."

"So..." Twi started with a smile. "How was that?"

The darker purple mare closed her eyes and smiled. "Incredible..."
