Before going to school one morning you were at the track for a run. Ever since you started getting hunkier and more muscular you couldn’t help but want to be fit and work out. Most of your ‘friends’ seemed to be enjoying the new look you were sporting the girls frequently eyeing you up or getting to enjoy the various areas of your body that had swelled nicely.

Of course, this morning your rival, and sometimes lover, Homura was trying to keep up with you. She was at school so she dressed as a boy but you could see the slight curve of her body under her work out shirt.

“Come on slow poke.” She ran ahead “What are those muscles just for show?”

You laughed at her egging you on.

“I bet you can’t catch me.” She took off into a full sprint.

Normally you’d let it go but that was a challenge you had to prove you weren’t a push over. You chased after her, your toned and muscular body had plenty of energy to spare and frequently surprised you with how well you were able to move with it.

“AH!” Homura moaned as you caught up, tackling her onto the grass.

She laughed a bit as you hugged her down.

“Don’t look so smug of course you managed to catch up.” She pouted “If I was a real guy, I totally could have out ran you.”

“You had the advantage cause of all those muscles.” She blushed and licked her lips a bit “Stop staring down at me like that, you look like a lion that just caught a gazelle.”

She was right though you had chased her down like a predator after prey and it was a bit exciting.

“What are you doing?!” she yelped as you started pulling her shorts down “You can’t be serious not here someone could see!”

You couldn’t help but smile a bit, that was half the fun. You shimmied your shorts lower and got your thick cock out and rubbing against her pussy.

“OHH!” she moaned her hands digging into the grass “HMM!”

You grind your hips forward, cock going in deeper as you fuck her roughly in the open. She looked up at you with an eager embarrassment, the adorable look only driving you to fuck her even harder.

“HAAA!” Homura let out a powerful yell as she orgasmed, her body shaking and shivering with erotic bliss.

With your own satisfied grunt you give her a few shots of your cum before pulling out, big cock getting flaccid and easily tucked in before long. Homura moans and lays on the ground a bit before you tell her to get back up and shower off, you two will need to get to class soon.

Most of the school day was uneventful but today you have science class with Professor Haruka. He’s a bit of an odd ball with short brown hair and a thin body under a very neatly kept pants suit. He’s still new, up until a few months ago your math Teacher Professor Rin was also the Science teacher but they brought in this guy to lighten the load.

You are seated at the back table with your lab group, Ikaruga and Katsuragi. In the past your table was always a bit strange, the Class Representative a pervert and a normal guy…but given your recent changes and relationship with the two things were a lot livelier in the back.

“HMM!” Ikaruga moaned as you reached over and playfully pinched her butt “N-Not in class.”

“Hehehe.” Katsuragi snickered a bit.

You were standing in the middle, with Ikaruga on the right and Katsu on the left so once the blonde started to tease you showed her a bit of affection too, reaching over to give her rump a squeeze. You were in the back so no one seemed to notice that you were full on groping two of your classmate’s juicy rears in the back row. You barely listened to the lesson instead just helping yourself to the buffet of booty, hands sinking and squeezing against their girlish bottoms that until just a few weeks ago you assumed were male.

Before you even realize it the final bell is ringing and it’s time to go home, both your friends are bright red and turned on to the point it seems like they want to jump you right then and there but before they can get you out into the halls you’re stopped.

“Excuse me, may I speak with you in my office?” The Science teacher askes.

Oh no, had he just seen what you guys were doing. You send Ikaruga and Katsuragi on their way and follow the teacher.

“Take a seat, I’d like to chat.” He closes the door.

You nervously sit down and watch the man walk around. You don’t say anything, unsure of what punishment could be coming.

“I can’t believe it…really I can’t.” he says sitting on the desk “You’re really right here in front of me.”

Now you’re starting to feel confused.

“Fufufu…I suppose you wouldn’t understand in this state.” He said “Better I show you.”

He steps back and like a magician at a show tears off his suit and reveals a stunning pink and white singlet underneath, but that’s not all he’s now showing off some wonderful hip and two large soft breasts.

“Hmm, that’s much better.” She says twisting her hair a bit so it pops into curls “That suit is so restrictive and uncomfortable.”

Somehow the fact that your teacher is also a woman isn’t all that surprising, frankly these days nothing is.

“Now then I’m sure you have many questions, I think I might be able to shed some light on.” She sits on the desk “Shall we begin with what you really are?”

You nodded; this was finally the chance to get some answers.

“I’ll start form the beginning; Ninja fight powerful beasts called Yoma.” She said “Years ago there was an incredibly powerful one with control over women. It was so powerful that the ninja of good and evil put aside their differences to destroy it, but its power was too great to be destroyed for good, it could only be sealed away. So, they came up with a plan and placed a heavy seal on the Yoma, trapping it in a dormant form. But what they didn’t know was that the Yoma was seen by some as strong and mighty, it was worshipped like a deity and those who did so would never allow their master to be put into eternal slumber so they used members that were present in the schools to secretly weaken the seal so that in time their master could return to his full strenght. They soon found out that the Ninja were keeping the Yoma dormant by tricking it, it’s memories wiped it was being led to live a false life under the constant surveillance of Ninjas and given it’s attraction and power of women it was made to be told everyone around it was a male even if that was a lie. They then developed another idea, to keep it here while they researched a way to use that power to make a new stronger generation of Ninja warriors.”

Haruka smiled “I am one of the agents of that cult and you…you are our beloved Master!”

It was all so strange and bizarre to hear but…it also felt so true.

“We had anticipated that it would take years, decades even, for the seal to weaken and your powers to begin returning but it seems to have started sooner…perhaps it’s due to your rather strong libido and the fact you’ve been having sex. Regardless your powers are returning you’ve no doubt noticed how women are being more drawn to you and desiring you just by seeing you or that your physique has changed at a marvelous rate.”

You nodded, it all added up.

“I was only a rookie member of the cult when you were sealed away, I never got to see your true form myself but those who did said it was marvelous, the most strong and handsome man they’d ever seen, even fantasying about it couldn’t capture the true beauty of what you were.” She sat in your lap “But Master there is a problem.”

You tilted you head, a bit surprised by her calling you Master.

“You’re always being watched, it’s no doubt going to get back to the Ninja High Commands what’s happened to you.” She said “And this time in your weaker state they may really try to kill you, or worse seal you away in an eternal slumber!”

That sounded bad.

“Don’t worry we’ll think up a plan to keep the higher ups, the teachers, that make the reports here from passing things along, they’re the only ones that know the real reason you’re here, everyone else just thinks they’re supposed to watch you not why they need to watch you. HMM Master~”

You noticed her moan and then realized without even thinking you’d started rubbing her thigh.

“We’ll also need to make sure your powers are progressing, in other words.” She smirked “You need to keep having lots of sex and not just with the same people over and over, you’ll need to branch out…make new conquests.”

You smiled as she leaned down and kissed you “MHH!”

You started kissing back, hands soon running all over her body holding on to her plushy thighs and reaching up and getting a good handful of her big tits, the largest you’d seen so far.

“OH MASTER!” she moaned as you started sucking on one of her nipples, tongue flapping around and swirling her areola.

Haruka was drooling a bit, all to happy to give herself to you allowing you to suck on her tits and reach down to start rubbing her pussy with your left hand.

“HAA!” She screamed out as you pulled the crotch part of her singlet to the side and got your fingers inside her wet cunt, pushing them in and out and hearing the satisfying schlicking noise.

You never stopped mashing you head against those sweet titties as you did so either, sucking and kissing, motor boating and munching.

“Your hands are so big and warm!” Haruka moaned “And your tongue is-AHH!”

She shivered in your lap, legs twitching as her pussy twitched and squirted. Of course that wasn’t enough for her, or you either for that matter, and she threw herself onto her desk, sticking her ass out and practically begging you to fuck her raw right there.

“MASTER!” she moaned as you pushed right into her, you wondered about all her screaming attracting attention “Don’t worry the walls are soundproof-HMM!”

That was all you needed to hear from your follower to get going, hips pumping rapidly as she squirmed under your muscles, soft breasts squished against the desk as her ass clapped against your body.

Your big cock plunged deeper and deeper, the feeling of dominance over her making you even more excited and turned on. You panted and hissed more and more, balls slapping against her body, thick thighs acting like cushions for them as you went deeper and deeper, both of you moaning together as you approached your mutual limit.

“Master I’m…going to…ohh!” Haruka gasped starting to cum, her body squeezing and pulling at your cock.

You grunted a bit, cumming with her and feeling up her ass as you did so before pulling out.

“That was amazing Master, I’m sorry I came so quickly.” She apologized.

You held your hands up telling her it was not necessary.

“You’re modest too Master, I like that.” Haruka smirked having you sit as she got on her knees slowly stroking you a bit “Fear not Master you have allies here and with our help you will return to the position you once had…maybe even higher.”

You leaned back and moaned as she started sucking you off, you weren’t sure where things were going from here, but it sounded like it would be exciting. When you thought about the Ninja association trapping you here you got a little angry, you had no memories of your time as what you were but the emotions seemed to still be there. If they were going to trap you then you would make them regret it…and thankfully they’d put some of their strongest warriors here for you.
