>Two days ago, while going back to the classroom I noticed Obsidian Stone trying to enter the little mares' bathrooms.
>With his penis fully displayed.
>I swear, these foals don't know self-control. Wish they'd be in my place for once.
>Teaching colts during mating season is hard, you know.
>I know that they're kids and that it's wrong, but the heat is strong at times.
>I must keep my composure. I can't be seen lusting for a student. I could get fired, or imprisoned!
>Back to the topic though, I caught Obsidian trying to... Go wild... With the fillies.
>Our school has a very strict protocol. Horny uncontrolled foals get their genitals magically severed.
>It's a painless process that can be reverted without magic. Just take the penis or vagina, magical click and clack and you have a functional (and still connected to the foal) genital. 
>We keep them in teacher's storage until a parent of the foal comes to get them back and sticks it back on.
>It is kinda weird, but it's better than letting the horny colts go wild on the horny fillies. We can't afford another mass teen pregnancy scandal on the school. 
>Yeah, I know, I was one of those teens back then, but my point stands. Horny foals make dumb decisions.
>I took Obsidian to the detention room and did the spell. Click and clack. 
>One more penis on the storage room.
>Obsidian begged me to return his penis, he can't afford the embarrassment of asking his parents to take it.
>I apologized, but rules are rules. He should've shown more self restraint.
>The day ended and we all went back home. The heat's been killing me, and I had ran out of suppressing medicine.
>I'd have to buy more tomorrow. But for now I had an excuse to go wild. 
>I took one of my dildos (Any self respecting mare has at least a pair, right? RIGHT?) and went to town on it.
>Look at me, what a hypocrite. Telling my students to show restraint when I can't spend 24 hours without the meds and not fucking myself silly.
>The rings delectably scratched my special spots while I played with my clit. I came wildly and fell asleep on the couch.
>I woke up in my bed the next day, dildo on the box and blankets over me.
>Celestia, Pearl found her mother fucked silly and took her to bed. S-She'll understand, right? She also has needs-
>Perhaps she had some medicine!
>I rushed to her room, but she was gone, and so was her pill bottle. Odd. Usually I wake up first.
>I checked the clock, I was late. If I didn't hurry I would not make it to the first class.
>I'd have to teach a whole day without my medicine. Not good.
>And I can't ask for a day off. We need the bits.
>I awkwardly made my way to the school, legs buckling every time a stallion passed by and I caught a whiff of their delicious and... thick... musk.
>I'd have to try my best. Nobody can say that Clear Rose doesn't have willpower. I'd go through the day safe.
>Surely.
>I arrived at the classroom 2 minutes before class start, all the students were already there.
>First period went by relatively easy. I had a bottle of water to refresh myself whenever I started feeling funny.
>Second period was a bit more difficult. I could feel the sweat forming on my forehead and my horn starting to tingle.
>I wanted to be filled. Desperately. 
>Only 5 more hours before the workday was over. I could do it.
>I jiggled my way to the teacher's room. I needed a break. Class be damned, the students can survive.
>When I arrived, I saw Ms. Ruby taking her break.
>She took a glance at me and looked extremely worried.
>"Are you ok?" She asked. I nodded absentmindedly. Mind too foggy to make heads or tails of the situation.
>I meandered to the bathroom and washed my face. The usual pale pink, replaced with a very deep crimson. Not good. Everyone can notice. 
>I'll never live this down!
>"Hit you strong too, right? There's should be medicine on the storage room."
>For that one moment, I fell in love with Ms. Ruby. She was my savior. A fire-mare putting off this raging inferno.
>I thanked her deeply and rushed to the storage room. You'd be surprised at the kinds of things the foals bring these days.
>A yoyo with razors, fireworks, one stallion even brought some old school porn, those you'd find in your grandfather's secret storage.
>I searched desperately. But I couldn't find those pills.
>Did someone take them already? 
>I was about to leave when my nose betrayed me.
>I smelled the impossibly thick smell of a stallion in rut.
>Confused, I kept looking. Not for the pills, but the source of that exquisite smell.
>It was... Obsidian's penis. Rock hard in both a literal and figurative sense.
>That explains why he was so adamant on not having his parents come get it. He was in a very deep rut.
>I tried to resist the temptation, but I ended up taking that severed penis and inserting it deep inside me.
>I convinced myself nobody would notice. I'd get to the classroom, teach the students, put the dick back and rush my way to the doctor to get more suppressants.
>In hindsight, anyone with decent eyesight could've noticed. The black thick patch where my vagina normally is. The bulging belly. The awkward walking.
>With a somewhat satisfied thirst, I walked to the classroom, each step causing the penis to twitch, in turn making me twitch as well.
>I entered the classroom, a lot more calm now that I had something filling my insides. 
>Everyone gasped. 
>They noticed. There was a severed penis inside me. Not a dildo, but a student's penis. Some colt's names were thrown into the air.
>I pretended not to notice, both for me and Obsidian's sake.
>I sat down on my chair and started with the lesson. Frequencies and Rhythm. 
>Every mention of rhythm made me fantasize rhythmically riding Obsidian to next week.
>My mind fantasized, but my body reacted. I instinctively started tightening and loosening around his penis.
>I couldn't stop. It felt way too good.
>I could feel him pulse inside me, and he could feel me tightening, ready to receive his seed.
>All the students were looking around now, desperate to find the offending stallion. 
>He came. I froze in place. I had never felt so much release. Edging for a whole damned day. I came as well while looking, eyes unfocused, in his general direction.
>Miraculously, he never made a sound.
>One of the class jokers said that I looked like a lava lamp.
>We all laughed. I looked at my back.
>He was right, I was filled with thick and warm seed. Enough to make my tummy bulge slightly.
>I unconsciously smiled and went back to the lesson. Now mind and body relieved.
>After a few minutes, I felt his penis go soft and I looked at my bottom again. No seed to be found. 
>I inadvertently curse under my breath and continue with the lesson.
>Every now and then I stole a glance at Obsidian. He looked dumbfounded. Eyes wide and mouth agape.
>The day ended and I hurried my way to the Teachers' room. Obsidian quickly followed.
>He didn't look like himself. Eyes unfocused and walking awkwardly.
>I wordlessly took off his penis from me and gave it back.
>He put it back on and jumped on me.
>I pretended to resist, but we both knew we wanted this.
>A few hours passed, we were alone in the school, humping and pumping still. I had gone almost fully white inside from all the seed.
>Once we came to, it was already morning. Lucky stars it was Saturday, nobody would notice us.
>We separated, much to our bodies' displeasure. I was about to beg him not to tell anyone when he spoke.
>He explained he had had a crush on me for a while, but I was so uptight that he tried going for a student. Moment when I caught him and this whole debacle started.
>We promised to never mention this to anyone, but perhaps we could do it again.
>And we did. Every Friday we'd come to the storage room and go to town on each other.
>I had been very much alone. Pearl's father died soon after she was born. And I ended up raising her myself.
>Once again I felt desired and loved. His passion filling me, both emotionally and literally.
>A few weeks later I started feeling very dizzy. Vomiting, generally awful.
>I took a day off and went to the hospital.
>I had to wait for a while, but eventually I got checked.
>The nurse mare told me I was pregnant.
>How would Obsidian react, I wondered.
>The year ended and all the kids graduated.
>All this time, my belly growing, this time because of life, not passion.
>The students and colleagues all wanted to know who was the father. But we kept quiet. Until he graduated.
>He proposed to me publicly after the graduation and I said yes.
>We're happily married now. 
>Pearl was a little uncomfortable knowing a stallion barely 3 years older than her was her new stepfather, but accepted it after a while.
>I'm waiting on the fourth foal now. Who'd have know this is how we'd end up?
