Thinking about what happened at lunch turned out to work against me as my dick was sporting a half chub by the time I walked into class. Thankfully it was still concealed under my skirt. Telling my friends and doing what I did with them was one thing, but exposing myself to my class and possibly having an orgy was another.

On second thought, that could be fun. I wonder how big Mr. Doodle is? The perverted side of my mind thought, but I immediately squashed the thought.

As I entered, I simply stated that I took a bit longer in the bathroom after lunch, which was not a complete lie, and sat at my seat. Class began and my mind became occupied with the very complicated trigonometry we were learning. To my silent relief, a half hour into the class my penis became flaccid again.

The class was mind numbing. Which was a good thing with how much had happened in the last 24 hours. I found the perfect way to relieve stress and it was very pleasurable to others. It was still very strange to have a dick and be a girl, but it was turning out to be a good thing. I did however want to seek out Tree Hugger after school and find out if she knew what Zecora’s potion would do. She had to have known, right? Zecora mentioned her by name.

I was tossed from my thoughts when Featherweight tapped me on the shoulder. I turned and gave him a puzzled look. He simply put a folded piece of paper on my desk and got back to his work. Curious I unfolded the note, read it and my heart skipped a beat.

‘I know what you have’ was all it read and to hammer the point home there was a crude drawing of a penis next to it. I quickly scanned the classroom. Feather likely was not the sender of the note. He was not likely to have been in the girl’s room at lunch since he didn't look like the type to sneak into the ladies room. Not to mention he was in a different lunch period. The only females I shared a lunch period with that were in the room were Toola Roola, Twist, and Petunia Paleo. I was sure the bathroom was empty and remained empty while I had sex with Scoots and Applebloom, but I only checked before...not after.

After that note I couldn’t focus on classwork. Someone knew about my dick that I hadn’t told, but who?

I thought about it for the next two class periods, but came to no conclusions. I’d even risked a boner in Art Class replaying the events of lunch trying to see if I remembered anyone entering the bathroom. Unfortunately all I could recall was our orgasmic moans. I also got sidetracked thinking about making my friends moan like that again in the future. I got turned on, but managed to hold back this time and not get a boner.

Finally I figured whomever it is would confront me sooner or later and I shouldn't obsess over it. My next class was gym and it was the last class of the day. I changed into my gym clothes in the stall of the locker room as to not draw attention to my bulge. My athletic shorts didn't do as good a job at concealing my bulge as my skirt did, but I hoped no one would notice...or if they did they simply figured I put on a little weight or something.

After gym I waited until everyone had gone home before stripping, this time not in a stall, and taking a shower. The smell of dry cum, spit and female ejaculate was not pleasant. Upon smelling it, I feared that it may have been how someone had found out my secret and then it could have been Featherweight after all. Only to realize it only really smelled once I took off Rarity’s silk panites so back in math class, no one could smell it unless they were right up against my crotch.

Abandoning the fearful thought I sauntered over to the shower to wash the sweat from gym and the fluids from lunch. I didn’t play with myself in the shower this time because I decided to text Scootaloo and study at her house since her folks were out of town.

I’d gotten an immediate response: ‘See you then, mistress. ;)’. At first I wasn’t sure how to feel when she texted me that. I didn’t want the fact that we had sex to change our relationship after all. But as I showered, I thought about the term more. The newly unleashed dirtier part of my mind imagined Scootaloo calling me ‘mistress’ while my cock was deep in her pussy’s embrace and I no longer thought the new nickname was that strange. My dick even hardened slightly at the fantasy, but I was going to hold out for the real thing.

I finished my shower and wrapped the towel around my waist. So if anyone came in they at least wouldn’t see the private part I wasn’t supposed to have. As if on cue, the locker door opened. I assumed it was Discord, the janitor. That was until I heard them speak.

“Are you sure she hasn’t left yet?” a very familiar and very bratty voice shouted angrily to another girl who had entered with her.

Oh no! Diamond Tiara! Why would she be looking for me?

“Um...uh...yeah, look her clothes and backpack are still here.” the other, quieter girl, I could only assume was Silver Spoon, responded.

The duo then turned the corner around the row of lockers and were looking right at me. Diamond wore the smug grin she always wore. Silver spoon just looked at the floor with a defeated expression.

“Well look who's the president of the itty bitty titty committy.” Tiarra sneered.

Instinctively I put an arm across my chest. My boobs were not nearly as small as Scootaloo’s, but they were no Zecora or even Rarity sized.

“What do you want Tiara?” I spat. I just wanted to get my clothes on and leave as soon as possible.

“Didn’t you get my note? Roola was so kind for passing it along. I hope you got it.” She taunted.

It was her? Diamond Tiara knows I have a dick? I’m screwed.

Seeing my expression she laughed, “Oh yes, I know what you think I know. But with something like this, I need proof or no one will believe me.”

“I-I don’t know what you mean.” I lied. She knew I had a dick, but she’ll be a laughing stock if she doesn’t provide proof and I wasn’t about to give her some.

“Silver Spoon, watch the door. Make sure no one comes in, including yourself. No matter what you hear. Got it?” Diamond ordered.

What was she playing at? I wondered as her lacky nodded and left the locker room, Silver Spoon usually helps back DT up in her bullying. If it is just one person, I might be able to overpower her.

I took a step to the left in order to try to pass her, but she reached out and grabbed my towel. With only one had holding it up she won the tug-a-war and snatched it away revealing my shaft. In the cold air the penis, still damp from the shower, began to stiffen. Diamond Tiara just stood there mesmerized. Had I not been stunned by the removal of my towel, I could have gotten out of there before she recovered.

“It's so big.” was all she said in stillness of the moment. There was a dreamy tone to her voice that I'd never heard before.

Finally I recovered, but Diamond Tiara moved a step closer and blocked my way. An onslaught of perverted thoughts invaded my mind of me bending Tiara over and sticking my dick into her.

“Y-yeah, I guess you could s-say it is.” I stammered, as I backed away from her and tried to ignore the dirty thoughts invading my mind.

“I told Silver a source told me you had a vag piercing.” Taira admitted, taking another step closer, her mouth forming into a seductive grin, “After what I saw at lunch, I wanted you all to myself.”

“So, you really want my cock?” I asked dumbly, “And you aren't going to tell everyone about it?”

“Yes because I don’t like to share.” she said huskily, removing her pink designer jacket and letting it drop to the floor, “It's the biggest cock I’ve ever seen and you know, secretly, I pride myself in being able to take big cocks.”

I felt the cold metal of the lockers as Diamond Tiara advanced further, drawn to my member like a moth to a flame.

“Then beg for it.” I felt myself say without thinking, the dirtier part of my mind taking control.

“What?” she asked surprised, not sure if she had heard me correctly. The request derailing her plans.

“You want my cock, beg for it.” I demanded again, acutely aware that my dick was stiff as a board. Do I have a thing for dominance?

“You're joking, right?” she fumed, “you should be honored that I’d want anything to do with you or your cock! If anyone should be begging it is you.”

“Well then, I guess I’ll just go.” I challenged, “I have a study date with someone more deserving of it.”

I moved away from the lockers and pushed past her. My unexpected defiance throwing her for a loop allowing me to get by with little struggle.

I’d almost reached my clothes when she finally responded, “P-please can I have y-your cock?”

I turned around to face her. Her cheeks were burning red from embarrassment. The satisfaction of getting her to submit to my demands was intoxicating.

“Whose cock?” I asked, taking a step back towards her, I was going to milk this as long as I could.

“Yours…” She began.

“Mistress.” I provided, remembering the text from Scootaloo.

“It is bad enough you are making me beg for something any guy would give to me in a heartbeat, but I will not call you that!” Diamond replied indignantly, her stubbornness outweighing her apparent need for my shaft.

“Welp, bye then.” I challenged again, picking up the panties I’d borrowed from my sister. They had some slight discoloration that I hadn’t noticed before. Cum stains?! Guess I won’t be giving this back to Rarity. In exaggerated slowness, I began to slip them on.

“P-please can I have your cock, m-mistress?” Tiara muttered under her breath.

I stopped and cupped my hand next to my ear, “Sorry, I didn’t quite hear you. What did you want?”

You could almost see the heat radiating from her cheeks as the last shed of her defiance waned, “Please can I have your cock, mistress?!” she shouted, her voice echoing in the empty locker room. There was an audible gasp from the direction of the door.

I smirked and removed the panties, “On your knees.” I ordered.

She dropped to her knees and looked up at me with the most need I’d ever seen, more so than Applebloom and Scootaloo whom were my only references.

“Please, mistress, I need your cock!” she pleaded once more.

I really liked this side of Diamond Tiara. “Then suck it like a good little slut.” I demanded.

“Y-yes mistress.” Diamond said without being prompted. She had taken to the submissive role very well.

She turned to face my cock and took the whole length into her mouth in one go. Her eyes bulging as it breached her throat. The soft, warm lining massaging it as she struggled for breath. She began to slowly remove the member from her mouth, but this was the girl who had tormented my friends and I for years. She was not getting off – or in this case getting me off – that easily. I grabbed the top of her head, pulling it up until the cock was almost out of her mouth before slamming it down again. The force pushing my cock further into her throat. She gagged and gasped for breath, but that only massaged my impressive shaft sending waves of pleasure through my body.

Not letting her rest for a minute I began to quickly move her head up and down. Each time breaching slightly further into her heavenly throat. Looking at her as I did, I could see tears forming in her eyes from the exertion, but that was not going to stop me. This was payback, sweet, pleasurable payback.

After a few minutes of this I began to feel a tingling buildup in my balls, but I wasn’t about to give her my cum yet. I pulled her head off my dick. It made an audible pop as it was released from her mouth. She sputtered and coughed as she was finally able to get a decent breath into her lungs. Using her sleeve she wiped the tears, smudging her mascara across her cheeks. She showed no signs of not wanting more. Like Scootaloo, she liked it rough. She may not have realized until now that she did, but from her expression I could tell she was liking the direction this was going.

“Up!” I ordered and she rose, “face the lockers.” She turned.

I lifted her short skirt to find she was going commando. Her womanhood was glistening messily with her arousal. I was about to slam her pussy as I had Scootaloo’s, but then I noticed her puckered, virgin asshole. I ran a finger across her slit covering it in her juices before I stuck it in her ass and began to massage it open. As I did she let out a breathy moan.

“You like that don’t you?” I purred in her ear, as I added a second finger, “You’ve been such a pain in my ass over the years, I’m gonna repay the favor.”

“Yes! Fuck me in the ass mistress.” she pleaded, “I’ve been such a bad girl. Punish meee-aaaah!”

Before she could finish I slammed my entire cock into her ass without warning. It was tighter than Scoots’ vagina had been. I almost lost it then and there from the tightness. Before I did, I pulled out and slammed it back in. I repeated this a few times slowly to let the saliva lube up the hole before I increased in speed. Each thrust slammed Tiara’s head against the locker, but I didn’t care, I was enjoying hate fucking my arch nemesis. She didn’t seem to care either as she began to moan with pleasure each time I thrust inside of her.

After a few minutes, Diamond Tiara threw her head back and let out a guttural moan of pure bliss. I felt my balls and thighs get showered in ejaculate from her explosive orgasm. Aiming to punish her more I reached the hand still covered in her juices around and stuck two fingers in her climaxing cunt. In time with my thrusts, I fingered her with reckless abandon. In no time at all the vaginal walls clamped down on my fingers in a renewed climax and a new layer of girlcum coated my hand, balls, and, thighs.

I removed the soiled fingers from her pussy and brought them to my lips. Slowing my pace slightly, I took a tentative lick of the juices. They tasted sweet with a slight tangy aftertaste. I thought about licking them clean when a dirtier thought took hold. With my clean hand, I pulled Diamond tiara’s hair to pull her head up. I then reached forward with the other and stuck the wet fingers into her mouth. Without being asked she began to greedily clean off her own juices.

“Yes, drink your own juices. Taste your own debauchery and like it.” I told her, once again increasing the speed of the pounding I was giving her.

I think she tried to respond, but between moans of pleasure and my fingers in her mouth, her words were lost. Though from the sounds of it she might have tried to say “Yes mistress!”

Then tingling in my balls built up higher and higher until I was finally pushed over the edge. I released rope after rope into her abused butthole. As I did my balls and thighs were once again soaked in Tiara’s third orgasm. I was satisfied by the euphoric pleasure and by the fact that I had just stuck it to Tiara in every sense of the word.

Finished with my handiwork I pulled my dick from her ass. A steady stream of cum trickled out and down her leg with my dick no longer blocking its exit. She fell to the floor panting, her face still scarlet red with streaks of mascara saturated tears. Wanting to give her one more memory of our encounter I picked up her discarded jacket and cleaned myself off with it before dropping it on top of the now sleeping form of Diamond Tiara. I was sure to use the part that sported her custom diamond tiara picture. I hoped it would make a very noticeable stain to remind her of her new place under me.

Content with my actions, I got dressed and left the locker room. On my way out I passed the stunned, beet red Silver Spoon who no doubt heard, and possibly watched, what had transpired.

“When she wakes up, tell her if she wants it again, come find me.” I instructed as I passed, “And if you want some too, just say so.” I purred into her ear, still riding on my power trip.

The only reply I got was high picked squeak, I took as her understanding. Without another work I marched confidently down the hall and out the door.

Author's Note

if anyone is confused by the period structure I used in the story it is as follows:

1st period
2nd period
3rd period
4th period/lunch
5th period
6th period
7th period

4th period is divided into 4 lunch periods (A, B, C, and D) with roughly 1/4 of the school being served in each. Sweetie Belle has D Lunch (kind of an unintentional innuendo).

no one really cared...they only came for clop...but I wanted to explain.
