To say Cadence finally felt relief after they left Red Star was an understatement. Despite the 'spider diish' there were no further incidents, fortunately. As they walked out of Red Star she couldn't help but notice how much Shining and Twilight tried to stay close to each other. She couldn't help but wonder how many times they've disguised flirtatious moves as innocent sibling love. She could only guess it's happened a lot.

Walking away from the restaurant and towards the castle Cadence thought of something. What next? Will this keep on forever? Will it stop someday? If so would it end in a good way? She had a lot of questions and no answers. She could only hope she could find a solution soon enough no matter what it takes.

"It's getting kinda boring" Scarlet complained.

"Oh trust me it'll get better soon" replied Abe, playing with one of his tentacles.

"How soon?" the filly shrugged in annoyance "Make it fun right now"

"Si të urdheroni, zonjë" Abe smirked and got up approaching the magical surface and putting a finger on it. He grinned and chuckled as his eyes turned all black.

Chaos broke loose. Apparently some crystal ponies recognized Spike and he was now running for his life away from the crowd, with Starlight chasing after to help. Pinkie Pie forced Fluttershy to enter a singing competition while Rainbow Dash and Applejack get too competitive to the point Rainbow decided to forcefully grab Applejack and take her towards the sky to see if she feared heights or not. Didn't take long for Rarity to get distracted by some fashion parade that was happening nearby and also dip. Cadence didn't even remember anything about a fashion parade happening. At the very least she hoped Rainbow didn't drop Applejack by accident. But something good came out of all this. She was now alone with Shining and Twilight. Well, unless you counted Flurry but she wouldn't cause any issue.

"So," Cadence decided to speak "Anything you'd like to do?"

"Well i was planning on some group activities before all my friends scattered around like pigeons!" Twilight replied a bit pissed off. Cadence couldn't really blame her. She could only assume she planner a whole schedule for coming her as is usual for her and now all that was kinda blown away. Still, it didn't mean it was all bad.

"Don't worry much about it, look at the bright side. Now you have more time to spend with us"

Twilight smiled "Yeah, i guess you're..." she looked around in confusion "Where's Shining Armor?"

Cadence now was made aware of the absence of her husband and also her daughter. She looked around in worry until she finally spotted them both. Flurry chasing after some bird and Shining chasing after her hoping to catch her.

Both she and Twilight giggled at the adorable display and decided to let Shining deal handle it on his own. Together they headed to the castle and went inside. Once they reached the parlor they started chatting around about different things. There Cadence decided to strike.

"So Twilight, any love interest yet?"

Twilight just froze in place, looking at her with wide eyes. She was more than surprised by the sudden question. Her cheeks turned red and she gulped, barely resisting the urge to back away a few steps.

"W-what? I-i don't have any. Why do you ask?" it didn't take somepony with Cadence's skills to understand she was lying. An attempt which made her giggle out loud, much to Twilight's discomfort.

"Please Twily, I'm not one you can easily fool with that. I'm the princess of love after all." Cadence said with a smile.

Although she tried to hide it, Twilight still had a glimpse of fear in her eyes. Had Cadence found out? Was she aware? Did they get caught? All sorts of things must be running through her mind at the moment. Cadence suppressed a chuckle. Oh she was starting to enjoy this. Knowing about it and using it to play with her like this gave her an absurd sense of sadistic enjoyment she didn't know she had in her.

"Come on, you can tell me. Who is it?" she came closer with a smirk on her face.

Twilight just got more and more nervous. A drop of sweat was falling down her forehead. She finally took that step back as Cadence approached. All her fear and terror materialized in her throat and she had to gulp it down. She looked right and left for a way to escape but to no avail. Finally she decided to give in and tell only half the truth.

"Okay okay you got me. There IS somepony I've been looking at"

'You sure that's all you've been doing'

"Ohh tell me" Cadence faked excitement "Who is it?"

Twilight thought for a bit. Her anxiety raising up she was in desperate need for a solution and she needed it fast.

"W-well. I'm not really ready to share it with anypony yet. I...I just want to keep it a secret for now, i hope you understand." she gave a smile, hoping Cadence will leave it at that. To her luck Cadence didn't really need to push much further either way. She smiled back and approached her.

"Don't worry sis. Whenever you feel ready" she put a hoof on Twilight's shoulder in a comforting manner "But at the very least you have to tell me about them you can't escape that" Cadence chirped

Twilight sighed. She could satisfy her with this. As long as she didn't give any information that will raise suspicion then all will be okay.

"So tell me" Cadence continued "Is it a mare or a stallion?"

"Umm.... a stallion" Twilight replied after a pause. She was going to have to be very careful with her answers. Should she say something that will reveal her and Shining things can go bad. Really bad.

"Ohh? Tell me, do i know him?" somehow Cadence found playing innocent rather pleasing.

"Ummm no... i don't think you do" She replied with a sheepish smile.

'Lieing to me, eh Twilight? Oh you're gonna get it'

"Tell me about him" Cadence acted exited and curious. Even though in all honesty she was a curious as to what drew Twilight to her brother.

"Well..." Twilight hesitated "He's... nice."

"And?"

"And, uhhh. Handsome" she blushed a bit when she said that

'Well you're not wrong'

"What do you like about him most?" Cadence went straight fir the big fish she hoped to catch.

"Ummm well... i like that he's a kind pony" her blush deepened a bit. It felt weird talking about this. Especially to Cadence. But at the very least Cadence didn't suspect anything about the identity if this so called crush and was simply asking about her love life in general. After all who could think she would ever have an affair with her own married brother.

Or so she thought.
"And also he's always been there for me when I've needed the most. And I've known him for a while. And, well, he's kinda handsome" she giggled sheepishly at that and blushed. An act that made Cadence giggle along.

"Well he does sound pretty nice. Have you made a move yet" at this Cadence wiggled her eyebrows, not letting much to imagination as to what she was referring to. Twilight blushed even harder and her nervousness levels got sky high.

"Umm... no not yet" she lied through her teeth with a sheepish grin.

Being lied to on her face made Cadence really angry, especially since she already knew the truth. She had to contain the urge to just pin her down and make her clean her hooves with her tears and tongue.... wait did she really just think of that? She mentally distracted herself from the thought and focused on the current situation. Despite knowing it was a total lie she chose to act convinced.

"Well whenever you feel read to take a step don't forget, I'm always here to help my sister" she said with a smile. Twilight smiled back.

"Thanks Cadence" The two shared a hug for a few seconds. But got interrupted by the sound of breaking glass and screams. They turned and saw Rainbow Dash carrying a traumatized Applejack with her. Upon landing she out down the farm pony who proceeded to crawl into the fetal position and rock herself back and forth.

"Who's the coward now, scared filly" Rainbow said with a cruel smirk.

"Rainbow!" Twilight yelled "What did you do to her?!"

"Huh?" Rainbow looked at Twilight "Oh nothing i Just took her really high, flew her through a storm cloud, did some acrobatics and crashed through that window over there"

"I'M NEVER FLYING AGAIN!" Applejack screamed bloody murder.

Laughter enveloped the room as both Scarlet and Abe enjoyed the chaos that was happening in Crystal Empire.

"Told you this was going to be fun" Abe said as Scarlet was trying to breathe from all the laughter

"I can say it's one of the best dates we've had so far" she replied.

"Oh it's about to get better" he smirked grabbed the filly with one of his claws and brought her face to face with him, giving her a small lick on her snout causing her to giggle. "How say we put my tendrils to good use"

"Oh my" Scarlet laughed and blushed a bit "You know what to say to put me on a mood"

"I'm known for knowing" Abe grinned and gave her a kiss "Now let's do a quickie before the good part starts"

"Good part?"

"Oh yes" Abe chuckled "You'll love it"

A bit later

After calming Applejack down the group finally gathered in the castle and then everyone sat for dinner, this time with less arachnid dishes. After that everyone went to their rooms for the night. With exception of Cadence, Twilight and Shining Armor.

"What a day, right?" Shining said

"Mhm" Twilight responded with Flurry flying above her head in circles like a shark.

"I'm glad you all decided to visit" Cadence added with a smile

"But of course" Twilight smiled back "I couldn't not visit you all"

"Twilight" Cadence said in a slightly more serious tone "I know you came here to check on me. Yes, my state a few days ago was less that good i will be honest about that but i assure you there's nothing to worry about I'm fine" she smiled comfortingly, earning another smile from Twilight.

"I know Cadence. But It doesn't mean i can't look after my you whenever i see you're down"

"I appreciate that" the two shared a hug making Shining almost shed a tear looking at the exchange.

"Well i say we drink something" Cadence said suddenly and went to a nearby shelf and levitated a bottle and three glasses from it with her magic.

"Ummm Cadence I don't think wine would be good right now"

"Oh nonsense Twilight" she said as she poured the wine in each glass, secretly putting something else in two of them "There's always room for more celebration. Besides we're only having one shot"

Twilight was a bit reluctant. She wasn't a big fan of alcohol in general. She looked at her brother and saw that he was simply smiling and decided not to let her own ideas ruin the mood for the two.

*Well who am i to say no" she finally said.

Cadence approached with the wine and gave them each their respective glasses.

"How about a toast?" Shining said

"To what?" Twilight asked

"How about... Our family" Cadence suggested.

Shining and Twilight smiled and nodded in agreement. With a toast the three downed their drinks and Twilight could almost swear she saw Cadence smirk when they did. But she chose to ignore it as her eyes playing tricks on her. The wine wasn't even in her digestive system yet and she already started seeing things. She didn't like where this was going. But again what harm could one drink bring.

Cadence looked at her back to see that Flurry had gone and used her as a makeshift bed and was snoring peacefully. Everyone present giggled at the sight.

"Well i suppose it's late. We should all go to bed for tonight." Cadence stated.

"Yeah i agree" Shining yawned

"Alright I'm also heading to my room" Twilight said as she hugged them both goodnight and headed off. Shining went to their bedroom and Cadence stayed behind with Flurry.

"Don't be late, darling" he said as he left

"I won't" she replied while cradling Flurry. As soon as she was left alone a devious smile formed on her face "To the family indeed"

Day was going fine. His sister came to visit woth her friends, his wife seemed in a better mood. But now all of a sudden he was painfully erect and aroused but Cadence decided that Flurry was going to sleep with them tonight.

She hadn't really slept with him in that way for a few days but with Flurry here there was no way she'd agree to do anything. Here he was, stuck with a raging erection but his own daughter in the middle of him and his wife. He needed to do something. Maybe go to the bathroom and finish himself? That could work perhaps. Whatever it was he needed to do something because it was starting to get painful. He'd never been this aroused before. He was even starting to sweat.

An idea came to his mind right then and there. Twilight was here. Maybe he could...

He slowly got up, careful not to wake neither Cadence nor Flurry. Even if she woke up he could make the excuse he was going to the bathroom. He slowly walked towards the door making sure not to produce any noise and left the room.

'Predictable' Cadence thought as she opened her eyes. She carefully let Flurry on the bed and got up as well. She cast an invisibility spell on herself and quietly followed after Shining.

That drink certainly didn't do well with her. Twilight was practically melted into her bed, simply laying lip and relaxed beyond what would be considered normal. She even had trouble mid way coming here. Her senses had hyped up and she could now hear and smell even the slightest of details in her room. She wasn't aware alcohol could have this type of effects. What kind of wine was that? Well whatever it was the message was clear. Don't do alcohol kids.

Trok trok trok

She heard trotting from outside her room. Didn't take long before the door creaked open with an almost deafening sound. Then more trotting.

"Twilight?" the voice of Shining Armor was heard whispering "Are you awake?"

All Twilight could do was moan in response. From outside it almost sounded like just sleep slurring but she was completely beyond the capability to form speech right now. However her ability to analyze wasn't gone and she could tell that Shining's voice was breathy and he almost sounded in pain. She wanted to open her eyes to see but whenever she did she just got welcomed by a variety of lights and colors greeting her and dancing around in her sight. She was essential useless and super sensitive right now. That's it, no more drinking for her.

"Umm" Shining continued "Can we like... you know... Flurry is sleeping in our bed tonight so me and Cadence can't and I'm really, really desperate right now."

The scent of must and sweat assaulted Twilight and overwhelmed her. She didn't need much time to figure out what Shining was talking about. Had it been a different situation she would have gladly helped him out. But right now it didn't seem like a proper situation to do any of that. Still not like she could really say no at the moment.

And not like Shining was waiting for a yes either. Right now he was thinking with pure instinct, whatever had gotten to him blurring his mind to the point he almost forgot where he was. Whatever left of his rational mind put up a barrier that blocked sound from going out. He climbed on top of the bed causing Twilight to flinch at the sound of creaking caused by the extra weight. Carefully but still frantically he positioned himself on top of her and moved her tail out of the way. The fact that Twilight was laying on her belly didn't make it any easy for her to do anything about it.

"Shhh...Shin..." she mumbled incoherently

Oh the side of the bed Cadence was trying to be as quiet and still as possible. With Twilight's enhanced senses she could be spotted despite being invisible. Not that Twilight could focus long enough for that anyway. Having put a powdered version of anthlexpine but with abit stronger effect on her drink and giving a dose of powerful aphrodisiac in Shining's she knew for a fact that what was about to happen would be essentially torture. She probably wouldn't divorce Shining and publicly expose them but that doesn't mean she was going to leave them get away with it. If Twilight wanted to sleep with her husband that much let's see how she likes it now that she can feel ten times more than what she normally would. Maybe they were right when they said Abe was rubbing his sadism on her. But at the moment it was so worth it.

Twilight's face contorted in what seemed to be fear as her breath deepened. Her cheeks were flushed with red. Shining himself was breathing even more heavily and was positioning his painfully erect penis in the entrance of Twilight's vagina.

"Wuuu-Wait..." Twilight mumbled again but to no avail. Shining wasn't present at the moment, mentally speaking. She could feel the tip of his cock trying to enter inside and even that felt more intense than anything she'd ever felt. She was already moaning, and even thought the nature of the situation her own arousal took her over eventually.

Without warning or care Shining pushed forwards and like that his shaft was enveloped by Twilight's inner walls. The alicorn turned into a screaming, shaking mess. With some new found strength she brought her head upwards and her eyes rolled behind her back as she yelled a primal cry. She fell back down with her face planting inti the pillow and her breath shakey. She'd never felt like this before. It felt good of course, but it felt too good. To the point it almost hurt. She could feel everything. He hadn't even started yet and she was already painfully close. Her whole body shook from the sensations. Her face was now completely red and was shaped by agony and arousal as tears fell from her eyes. The amount of overstimulation was unbearable.

Which is exactly what Cadence was hoping for. She smirked as she watched her little sister in law be reduced into nothing more than a writhing mass of overly sensitive flesh by not other than her own brother. A punishment fit of the crime, Cadence thought.

'Do her'

As if hearing her inner thoughts, Shining started rocking back and forth causing Twilight to scream and cry louder annd louder each time. Thank goodness for that sound proof barrier or else all Crystal Empire would have gathered here by now.

"NNNN! NAAHH! NUUUU!". Twilight tried again to plead to her sounds of pain fell on deaf ears as Shining was reduced to nothing but a wild beast right now as he kept thrusting in and out of Twilight and grunting, seemingly without a care for her cries. Eventually he picked up pace and started rutting her more viciously.

Twilight shrieked at the top of her lungs. She had never been stimulated to this point before. It didn't take long for her to reach orgasm and shake uncontrollably as she squirted all over Shining's cock. She tried moving away but she felt too week plus Shining was holding her down. It was painfully unbearable. She could do nothing but scream and cry out with every thrust that assaulted her inner parts with an avalanche of sensations and stimulation. It didn't go long before she had another orgasm. Then another. And another after that. It kept going on and on.

Cadence thought if she maybe over did it. There was punishment and then there was this. And as angry as she was she still didn't want to traumatize Twilight for life. Nopony would be able to survive this without some sort if trauma. Still, she told herself that it was already being done and she could do nothing about it. Instead she just used her magic to prolong Shining's orgasm so he could go on longer. She could tell that he was desperate to release but she wanted this too last and maybe that way she can also punish Shining by denying him orgasm as long as possible.

Not that he was complaining much. He just kept going even harder. His thrusts more fast and frantic. Twilight squealed pathetically, hoping for some merciful miracle that somepony came snd stopped the blissful torment. The pillow was soaked in tears and the sheets were soaked in their sweat amd her leaking juices as she orgasmed again.

"PLE... PLEAZE... PLEASE!" she yelled as much as she could for Shining to be done already and the torture to be over. Shining's thrusts were becoming even more violent and desperate causing her to shake uncontrollably from the overstimulation as she screamed again in yet another orgasm.

At that moment Cadence decided to let go and allow Shining to finish. On cue he ejaculated all he had inside Twilight, who could feel every shot of semen inside her. a minute passed like that and eventually he pulled out and collapsed into the bed unconscious. Twilight was shaking and convulsing violently, as if she was being electrocuted. Eventually she too subsided and fell into unconsciousness.

Cadence simply stood there. She looked down at her work, both of them being melted into a puddle of sweat, tears, semen and mare juices. Twilight looked completely destroyed. Her mane was a mess and she was still twitching at moments. Her face was still read from arousal and her eyes still flowed with tears. She almost wondered what they tasted like.

She stopped herself. Shocked that she would even think of such thing. But then she carefully looked at hem again to make sure they were fully unconscious and slowly leaned down towards Twilight and licked at the side of her face. The tears tasted somewhat salty with a bit if sweetness to it. She quickly leaned back up, not sure how to feel of ehat she just did. She decided to clean the mess she made. She cast a spell to mmake sure Twilight didn't get pregnant. Then she used another spell to clean off Shining before teleporting him back to their bed. She decided to leave Twilight like this to wake up in the morning and herself teleported back to her room and got back to bed. She stayed there awake with Shining and Flurry. Both of them deep asleep.

She thought of what she just did. She literally tortured them. And she kinda liked it too. But yet she felt somewhat guilty. Maybe she went a bit too far? She was suppose to use them to learn more, not ruthlessly hurt them. She thought of the state she just left Twilight in. She looked.... broken. Almost.... seductive really. And her tear did have a rather... interesting taste.

"Oh gosh..." Cadence said to herself "What's happening with me?"

She looked at Shining. He was passed out senseless. Seems he tired a lot. She leaned closer and kisses him on the lips, careful not to wake him. She would think about this again tomorrow. Right now, she also needed some rest.

Author's Note

Yes, you did just read this.

So a little update, I'm planning to use characters that speak multiple languages so there will be sentences such as "Si urdhëroni, zonjë" which translates to as you order, madame. Plus with a character like Abe it makes sense to make him multilingual.

Either way, yes Cadence has gotten a taste of the dark side. Where will this lead her? How would this affect her relationship with Shining and Twilight? What will happen from now on? To find out wait the next chapter to come out.
