Draft:
Twilight Sparkle, protege of the great Sun Goddess Princess Celestia, heroine of Equestria, and bearer of magic of the Elements of Harmony, was not having a good time. She was definitely not having a good time as she had just returned to her crystal castle. Earlier, she had gone off to Canterlot for an ambassador meeting between Celestia and the Gryphon Kingdom, which lasted quite surprisingly shorter than expected. It was expected to be about three days long, but it ended in merely under a day and a half. Yet, shorter didn’t mean better as the Gryphon ambassador was still quite the pompous jerk he was and kept insisting on pointless stuff their kingdom “supposedly needed”. Stuff that she now forgot as she was waiting impatiently for Spike to return.
And with her, Starlight Glimmer, her protege, was in the corner sitting quietly and twirling her thumbs for some time. For when Twilight returned home, she sought to get some deserved rest after such a stressful day. The problem though was on her way towards her bedroom, she came across the sounds of heavy moaning and grunts. Wondering as to what made those sounds, she went off to investigate, as the sounds were in the throne room, also in the same path as her bedroom. She only then regretted doing so once she discovered the origin of the sounds.
For as she arrived to the throne room, she saw her loyal assistant and half-brother Spike balls deep into her protege Starlight Glimmer, fucking her like a rabid beast. And Starlight seemed to be no stranger to such treatment as she was screaming his name in ecstasy.
Of course upon seeing this, Twilight did what most people would do in such a situation and put a stop to it… Only after a good ten minutes of watching it. It was hard not to stare, seeing her half-brother and assistant trusting into your student so roughly, their juices were practically all over the place.
Finally having enough seeing such a display, Twilight screamed, “What in Celestia’s mane are you two doing!?”
The two, finally realizing that Twilight had finally returned, stopped in both shock and embarrassment. Upon stopping though, Spike had stopped hilted all the way to the base with his hard draconic penis completely inside Starlight, leaving quite a large bulge showing around her stomach. It slightly pulsed and hitting a sensitive part of her that she couldn’t hold back a moan.
‘H-how can it reach that f-far..?’ Twilight thought. ‘A-and is she r-really enjoying i-it..?’ She quickly shook her head, trying to focus at the task at hand. “Spike! G-get off of Starlight now and explain yourself!” she commanded.
He looked a way for a moment before slowly pulling out of her, but not without leaving a long and agonizing slurping noise and a perfect view of his large penis leaving Starlight’s comforting hole. This also had Starlight show a very dirty look of both happiness and sadness as Spike’s penis leaving her pussy. With them finally separated, Twilight had a better view of Spike’s entire body, as well as his penis. Its length didn’t seem that different from other stallions, but its girth and shape definitely showed lots of differences. The fact that it looked so large, it was a surprise that such a monstrous appendage was even in a mare, much less Starlight. And the fact that it had these small ridges that were around the middle and nearing the curved top must have given her ideas as to how they helped in improving the pleasure tenfold.
Also, there was the fact that Spike was as slightly taller in height alone was a red flag that he must have gone some sudden changes when she wasn’t around. His thin yet slightly muscular physique and young yet mature look even though he was a young drake made her second-guess if it was really Spike she was looking at. Just a couple days ago she saw him and he was still a short and cute baby brother she remembered, only to return to see a complete 180 change of him. In addition that Starlight was the one he was plowing into without abandon was another shocker to her.
“Uh Twilight.. You still with us?”, Spike asked. Returning to reality Twilight looked again, still seeing the young-hot, steamy, sweaty, matu- “OK! Stop that!” she shouted to herself.
“Stop what?”
“N-nothing Spike.”, Twilight said. “Anyways. Go and clean yourself up and return back here, got it?”
He only nodded, as he grabbed a couple towels nearby and wrapped one around his waist, while giving the other to Starlight. As he left, Twilight was fuming, looking at the mess that was on her throne. As she was stuck in thought, Starlight said, “Maybe I’ll just go and-”
“Oh, no. You are staying right here. You also have a lot of explaining to do!”
“B-but I’
“No buts...I mean.. Ugh. You know what I meant.” Twilight sighed. “Just clean yourself up here and wait.”
Twilight had a serious headache just trying to get a grasp on the whole situation of Spike and Starlight having serious sexual relations in her own home. In a small way she was happy that Spike seemed to have given up on Rarity and went for another. The downside is that it was Starlight, who she thought had feelings for her old friend Starburst. And the fact that Spike looked like he got a serious growth spurt without her knowing, made her a bit upset and maybe jealous for not seeing such a discovery. While pondering on such things, she took notice of Starlight still wearing a towel over her body.
“Starlight, why are you still using that towel? Don’t you have some spare clothes to use?” Twilight asked.
“Oh… Well, they were shredded by Spike, before we had sex.”
Twilight was a bit surprised that Starlight was quite open with the fact that they had sex and that she was so casual of Spike tearing through her clothes like it’s nothing. Before she could ask Starlight to teleport some new clothes, she was already in the process of summoning them with her horn lighting a bluish hue and a new set of pajamas appearing. Twilight looked back and saw that the throne room was also cleaned from the mess she witnessed earlier.
After Starlight finished putting on her pajamas, they waited in silence. Which that was almost half an hour ago.
Present Time
“What is taking Spike so long?” Twilight said impatiently.
“Maybe he’s just getting some snacks or something,” Starlight replied. “You also did tell him to get cleaned up..”
“Well, he should already be done by now then. I can’t wait anymore.”
“Why? If you’re that tired, can’t you just go to sleep then and lecture us tomorrow?”
Rather than reply, Twilight just glared at Starlight in anger. Before she could get a word though, Spike entered the room carrying a tray of tea and an assortment of small cookies.
“Sorry i was late, I went to put on some decent clothes and went to prepare some tea and snacks for us since we may be here for a while-why are you looking at me like that Twilight?”
“Wha-how..? How are you a kid again!?”
“What do you mean?”
“Don’t play dumb! I saw you earlier taller and with a-” She paused. Twilight was slowly visualising sexy Spike again that she had to push the memory away before continuing. “Point is, you looked a lot different half an hour ago! Explain. Now.”
After placing the tray on the friendship table, he glanced at Starlight who in turn sighed and nodded back to him. Taking the gesture as approval, he then looked back before closing his eyes and emerald flames consumed him, revealing the very form he was earlier. It was odd that his clothes didn’t get burned from the fire or seem too big for his current 6 foot height from his original 4’8” feet. Looking at him too long started to make Twilight heat up in her cheeks so she slightly looked away and waited for his explanation.
“Well Twilight, as you can tell, me and Starlight-”
“You mean ‘Starlight and I’.”
“...Starlight and I have been dating for some time.”
“Well, it should’ve been obvious, the fact that no rational mare would allow some random stallion to mount her like that and for them to not be dating,” Starlight chimed in.
“Actually Star, there are some exceptions to that, like during estrus season. But I digress, back on topic. When did ‘this’ start? Why was Spike a teen dragon when I arrived? And why did you two have to have sex in the friendship room, right on MY CHAIR!?” Twilight yelled at the end.
“Well...To answer your first question, we thought you wouldn’t be back for another day or two and thought, ‘Since we already did it all over other parts of the castle, why not here?’”, Spike replied.
“All over.. You mean to say you both have been having non-stop sex all over the castle these past couple days I’ve been away!?!”
“No, that’s not what he meant…,” Starlight said. “Seeing as you’ve found us you may as well know that… We’ve been at this for quite some time.”
Twilight looked at Spike and then back to Starlight, then asked,” What do you mean, ‘some time’? How long have you two been at this?”
“Well… In terms of actual sex lately,” Starlight said. “ For the past few months.”
“But for dating and sex overall..,” Spike said. “...Ever since we arrived in Ponyville.”
After hearing that, Twilight snapped. Her eye twitched and her neck craned. ‘They’ve been doing this, ever since we’ve been in Ponyville..?? For that long!?’
Spike then said, ”I know you might be upset about-”
“Upset? Upset? Oh, no no no no, Spike I’m not upset about all of this, I.. am both furious, yet more confused at that statement. How have you two been doing this for so long, and without me knowing?”
Explanation exposition of retelling events relating to Starlight and sexy stuff between Spike and Starlight. Then as Twilight is slowly getting used to the idea of them dating and doing stuff...Even though they left out some parts beyond ponyville.
“I suppose I can be okay with that. I mean, you both are young and experimental. It’s fair to say you two were careful the whole time, and that that was all you did, right?”
Both of them looked at each other, their faces showing concern and worry.
“..Right?” Twilight repeated, now with more worry.
Starlight sighed, “Since we are laying everything all out, I may as well tell you, that it goes further even before you two arrived in Ponyville..”
“H-h-how-”
“Ever since we met in Canterlot months after you joined Celestia’s School of Gifted Unicorns” Spike replied.
She couldn’t believe it. She couldn’t believe any of it anymore. Not only have they’ve had sexual debauchery all over not only her castle, but all of Ponyville for some time, but it also goes so far as when she was in Celestia’s School of Gifted Unicorns?
“Before you get any weird ideas, I just want you to know-”
“To know what? That not only have you two been doing Celestia knows what for so long, that it all started when I was just going to school too???”
"Well.. not exactly. Just, hear us out before you chew us out for us.."
*Sigh* "Alright. Just don't expect me to be kind afterwards, alright..?" Twilight said.
"Thanks Twi," Spike said. "I know you're tired and all, and with finding out this... Yeah.." He scratched his head before continuing.
"To begin with, it didn't start sexual at all. We began as friends, and it all started in Canterlot. Right around the time you had just gotten in the school and I was being taken care of by mom and her staff..."
Explanation that they’ve experimented when they were younger, and find out the real reason Star brought them through time traveling.
First time is when spike and star meet at canterlot as children. star had just lost her friend and is being made to go along with her parents to meet celestia. While waiting, she goes off to the restroom to cool off from being impatient, gets lost while returning. Spike is also wandering around but finds star and helps her out. They don't know each other well so they start off as friends. A couple more meetings later, star hangs out with spike when both are a bit older. Spike introduces her his comics which surprisingly she is into a bit. They end up in a sexual position and spike kisses star. they get a bit heated in their kissing but then stop as star remembers she had to go meet her parents while spike goes off and helps out twi.
Time skip to a few months before twi and spike go to ponyville with star visiting alone, having already started a life for herself. Spike gets sad to hear that she will be leaving for a long while to find herself but she gives him a special goodbye gift which both enjoy. Present time Twi already got the idea of that that gift was and is conflicted about it.
Another time skip and it was before they go through the while time traveling thing, with spike getting a letter from star about trying out a few 'fun things' she had. Spike had heard her name from twi though and was unsure if the star he's been having relations is the same who's been a villain. He finds out that they are the same, but is oddly convinced to try out the dimensional traveling to have public sex. Not one to be against such kinky ideas, he agrees and during every jump, star and spike find a change to meet up and get shacked. Near the end, star agrees to reform (silently mentioning spike as her reason to reform) and becomes 'good'.
Then more recent events discussed as they get more open with their relationship and have others join in. Apparently nearly everyone in ponyville have at least joined in on their sexcapades; except a few (including twi) and end of flashback.
“...”
“Twi, you okay?”, Spike said worryingly.
“...”
“Yeah Twilight.,” Starlight said. “You’ve been quiet for the past few minutes and..”
“...”
“...”
“I...I just, need to be alone for now..”, Twilight finally spoke.
“A-alright. Good night Twi,” Spike said as he cleaned up the remains of their tea cups and plates. Starlight remained quiet as she followed Spike out, but not before taking a quick glance of Twilight still sitting, quiet.
As the two left, Twilight slowly got up herself and she walked back to her room in a quiet state. Once she reached her room, she laid herself on her bed and stared up at the ceiling. After hearing all of that, she didn’t notice her hands slowly reaching for legs. She only then noticed what she was doing as she found herself naked and with her right hand forcefully fingering her pussy while her right hand was kneading her breast. Just hearing all of that got her seriously horny, it wouldn’t have been a surprise if she got into heat from that conversation. All of those things that Spike did to Star made Twilight so envious that she tried to imagine herself as Starlight in all of those situations. Has she really been that needy that she had to imagine herself in Starlight’s place being ravaged by Spike multiple times? Apparently so, as she was nearing her third climax still recalling the various things she was told.
Meanwhile
*Spike and Star are going back to their rooms, Spike feeling down that they made Twi upset. Star reassures him and said it’s part of life and all, then teases him into wanting to finish what they started earlier. Rather than protest about it, Spike says a sly thing back to Star and agrees, both of them heading off to his room to continue.
*Twi moaning Spike’s name as she climaxes one final time. She then feels sad about being mean to them and goes to look for them to apologize, only to see them going at it again, and twilight now even hornier than before, finally joins in.
Outside, Carousel Boutique
**rarity is working tirelessly on a last minute order at night. Looking at her work, she feels close to finishing if she puts in a couple more hours. While thinking on what to add, she hears a near-deafening screams of Twilight in her joys of climaxes. Rarity blushes at the noise, and is somewhat happy for her that she finally got laid but also embarrassed to hear such sounds. She then starts to feel a bit stressed and horny and decides to go to bed and finish the order later, after some some self relief session.

Outline:
Twilight returns home early from an ambassador meeting in Canterlot. About to go to her room but curious where spike and starlight are at. While nearing her bedroom, she passes the throne room and begins hearing moans and grunts. Cautious that it may be some random sexual deviants, she tries to confront them, only to discover it was spike and star.
Twilight confronts them about it as spike and star are both embarrassed and upset for not being able to finish. Twi then slowly learns more about their sexual sexcabades and in the end she too get horny. Their sexual escapades began from when Spike was younger and Twilight was in The School of Gifted Unicorns. Another meeting was when they met a couple months prior to Twilight meeting Starlight. Another was when Starlight was bringing them through time travel, which upsets Twilight even more, finding out the 'real' reason for causing the whole goose chase through time.
Ending has her leaving to bed and tries to sleep, only for her to return and make it a threesome? Rarity hears from the distance while working on late night orders and hears the intense sex going on in the castle that she gets sexually bothered too before going to bed.
