This was initially meant to be part of the first chapter, but this part was getting a little longer than desired, so it's now bonus content. Enjoy!

Bonus Chapter

"What in Equestria were you two thinking?!" Starlight shouted.

The trio were now in Starlight's office, Firelight and Trixie seated in chairs with their heads down as Starlight paced in front of them. The classroom they had been in, now locked properly, and protected with a much stronger barrier that now also disallowed physical entry.

"Do you know how much more trouble the school would be in if a student found you? It's already bad enough that you both fucked in a classroom I tried sealing with magic, forget the fact you both got down to business with the door wide open!" She angrily shouted, her horn seemingly charging with magic.

"We're sorry, Honey Buns." Firelight tried apologizing before Starlight glared at him.

"And what did I say about those embarrassing nicknames?"

Firelight's expression dropped at her anger, and tried appearing smaller in his chair.

Starlight then took a deep breath and sighed as she tried calming herself down, "Look I'm not angry at you both for fucking."

"You're not?" Her father asked.

"A little actually, but, no. I'm more frustrated that somehow both of you decided to enter a classroom that had an aromarian barrier in front of it. My dad, I can forgive given I'm not sure if he knows what an aromarian barrier is for; but, I've told you what it does, Trixie, and it didn't occur to you that there was something in the air that was bad?"

"Oops." She sheepishly stated.

"In her defense, Sugarplum, the sweet smell didn't come off as 'bad'." Firelight argued.

"That's what I was worried about." Starlight stated before levitating the nearly empty potion bottle from the class and placed it on her desk, "The smell in the class was from this botched potion that Silverstream created as part of the class final. It really doesn't affect their grade if they messed it up, I just wanted to make sure the class knew how to make the No-Foal Potion if they ever need it and they can't reach an apothecary. I don't know how she did it, but the potion she created seems to have the opposite effect."

"Wait, the opposite effect?! You mean that..." Firelight then looked at Trixie with wide-eyes.

"Yeah, so congrads, Dad, you more than likely knocked up my marefriend."

Trixie and Firelight looked at each other with shocked looks as Trixie put both her forehooves to touch her stomach. After a moment, Trixie seemed to smile nervously and look at Starlight.

"Well, we did talk about having foals together someday." Trixie offered to Starlight.

"That was presumably after marriage, Trixie. We're not even engaged yet." Starlight sighed, "Technically, we can still stop it if we want to. An actual No-Foal potion is easy to make, and is good for two hours even after the fact. Problem is that I'm not even sure if it'll work after you both drank this one since it seems rather potent for some reason or another."

"How are you so certain that it's that strong anyway?"

"The potion is volatile for some reason, and turns to vapor easily. I didn't drink it, but it affected me after took the cork off for a couple minutes to inspect it. That's why I ran off, so I could use the showers in the gym to cool off. I'm already in my summer heat, I didn't need a potion making it worse."

"Oh, so that's where you went."

"Well, that, and I had to check with the other students. I wanted to make sure they weren't affected."

"Well, if it means anything, I don't really mind." Trixie stated, "If I'm correct, my heat would've happened during vacation. Now, Trixie doesn't have to worry about it."

"Yeah, you'll just be pregnant for nearly a year." Starlight dully remarked with a smirk.

"I'm willing to help if need be. It takes two to tango afterall, and if anything it just means I can come visit more often." Firelight stated.

"Great..." Starlight groaned to herself, "Well, it's not like I'm planning to break up with Trixie anyway due to a potion mishap. It's earlier than I wanted, but I guess having a foal around would be nice. Though that does pose the question all the same, why are you here, Dad? I told you I'd come visit you at Sire's Hollow."

"And, yet, you haven't made good on that promise. You haven't visited since that incident years ago when both you and Sunburst came to visit on your mission."

"I've been a little busy." Starlight sheepishly offered.

Firelight snorted in response to that, holidays were a thing afterall, "So I figured if you weren't going to come visit, I'll come visit you instead and surprise you."

"Oh, I was surprised alright." Starlight smirked, "It's pretty surprising to find your dad muzzle-deep in your marefriend's crotch while she moans like a whorse."

Firelight nervously chuckled as he brought a hoof the back of his head.

"Wait, how did you know about that?" Trixie asked.

"Hm? Know what?"

"That. You just said you found your Dad with his face near Trixie's crotch." Trixie replied, "But, when you 'found' us earlier, your dad was just finishing stuffing Trixie." She then pointed to her stomach.

Firelight's eyes widened before looking at Starlight, "That's a good point. We didn't even know you were there till you shouted at us."

"Oh! That, well, I...uh..." Starlight stammered, now it was her turn to be nervous.

"Glimmy." Firelight stated with a serious tone.

"I-I...You see..." In the end Starlight just smiled a nervous grin as she looked at her father, not sure how to respond.

"Starlight Glimmer, just how long were you behind us?"

"Was it the same time I had his cock in my mouth?" Trixie asked.

"What?! No! I didn't see that." Starlight immediately answered, "I saw you both exactly when he was under your tail, and based on the sound, he was...servicing you back there." She explained with a blush.

"So you just watched us that entire time?" Firelight asked.

She didn't respond, and looked away from them before saying, "I know that Trixie and I did talk about the idea, especially since she doesn't know her Dad at all. So I knew it was going to happen at some point; but, yeah, I just watched you both from the moment you were licking Trixie's privates to you fucking her silly. I know I should've spoken up sooner, and I know it's going to be weird for you to hear me say this, but watching you two was hot. Blame my heat if you want, but your dick going in and out of Trixie's marehood was probably the hottest thing I've ever seen. Only second to seeing her in those special lingerie socks she uses once in a while anyway."

"Cute save." Trixie remarked.

"That really got you going that bad, Sugarplum?"

Starlight shifted uneasily from where she was, her tail flicking sporadically, "Yeah, it did."

Trixie then had a mischievous idea, "Did you want to personally see it yourself?"

"What?!"

"I'm asking did you want your Dad to do you the same?"

"I'm not fucking my own dad!"

"Just felt like I should ask." She shrugged, "You sounded like you thought that big, pink rod he calls his dick was fascinating to you."

"That's not-" She groaned and facehoofed, "I mean, it really was kinda impressive. I never thought that my dad was that...big -then again, what daughter wonders how gifted their dad is anyway- it doesn't mean I want to get laid by him."

"It does feel amazing, Starlight, and it can help put your heat out at least for a little while." Trixie remarked as she approached her.

"Don't I get a say in this?" Firelight rang in.

"No offense, Dad, but I think that Trixie and I kinda have an idea of your opinion at the moment." Starlight remarked as she pointed below him.

Sure enough, the tip of his stallionhood was starting to peak out and getting ready all over again. His dick seems to have it's own agenda today.

"He seems okay with the idea, if even a little bit." Trixie whispered to Starlight in a breathy tone.

"Trixie, I swear, next time when it's just you and me."

"So, you want to give it a try."

"I guess it would be nice." She conceded, "Are you okay with this, Dad?"

"Not really, but I'm not completely oppose to helping you out, Sweetie." He remarked.

"Alright, but I'm taking a real 'No-Foal Potion'. I don't want to add another foal to our family this soon already." Starlight stated before levitating a potion vial out of her saddlebag, and floated it in front of Trixie's face, "Just so you know, Trixie, this is what the potion is suppose to look like. It's light-blue, not magenta."

"Yeah, yeah, yeah." Trixie waved it off while Starlight downed the potion, followed by Trixie kissing Starlight on the lips.

The pair remained lip-locked for several seconds, before slowly pulling apart.

"Cotton candy...?" Starlight asked curiously.
