The Self-Defense Pill (Tg) (Patreon)

The time has come. Kelvin gulped, standing in the shadow of the school building where most people wouldn’t pass. But that was the point, as what he had planned was something that people were not supposed to see. People besides Max, that is.

“I am surprised. It’s not often that I get a text message with such choice words like you prefer to use.” A pissed-sounding male voice rang out from behind him, making Kelvin freeze for a moment, before turning around to see the almost 1.9 meters tall muscle-packed quarterback of the school, who just happened to be Kelvin's most hated person on the entire campus, Max.

Max stood upright as he crossed his arms, making himself tower over Kelvin. “But alright, I get ya. You wanna talk, and I am all about settling things with words. Now tell me, what is it you feel like you have to say in private with a ‘muscle filled playboy’ like me, as you so eloquently put it.”

Kelvin shuddered for a bit before collecting his courage. “I-I’ll say it to you now one f-final time. Stop harassing me! Your c-constant antics of…”

“Harassing you? I can’t remember a single time where I outright said something mean to you. Aren't you shifting blame here? As I recalled you asked me to let you join our activities in and after school, and I let you join us. It’s not my fault that you make a fool and laughing stock out of yourself wherever you go,” Max interrupted, waving away Kelvin's argument.

“That’s not… You are… you are making my life here miserable!” Kelvin exploded, but Max just rolled his eyes.

“Yeah, yeah. Keep telling yourself that. Maybe one day you will find the maturity in yourself to look inwards for improvements rather than projecting your faults outwards.” Max shook his head, making Kelvin shake with anger. Then the quarterback followed up with. “Anything else you wanted to say, or can I leave? Contrary to you I have two girls waiting for me.”

“Do I have anything left to say… Oh yes, I do…” Kelvin mumbled as he sat down his bag on the ground beneath him and rummaged through it, smiling evilly as he fished out a small container housing a single medical pill inside. “You are going to regret everything…”

“Are you serious? Do you want to poison me? I am just saying that you will get that thing nowhere near my mouth, or else I will punch you and call the cops.” Max said, with an unamused expression and carefree tone, not at all worried.

Kelvin laughed and swallowed the capsule whole. “This… is a Self Defense Pill! It will turn me into your worst nightmare, so you better be ready!”

Max threw his bag over his shoulder. “Aha. Anyway, my girls are waiting. Catch you later, my worst nightmare. What a joke.”

Kelvin grinned. “No, you are not going anywhere! This will be the time that I destroy you!”

The pill resonated through his body, making it heat up. A blush adorned his face which turned into a smile as Kelvin knew that it was already starting to work. Gurgling noises came from his stomach as it began to settle. And when he patted it, grinned at what he was feeling.

“Yes! More! Your power will be nothing compared to what I am gaining! I’ll pay you back everything you did to me!” Kelvin flexed his arm which caused a visible ball of muscle to form there. His grin now grew even wider. “Now, this is some good meat, wouldn’t you agree? I wonder how it will feel when I give you a good bop with these guns!”

“What the heck? What sort of crazy pill did you just swallow?!?” Max asked with an open mouth.

Yet despite how much the muscles formed on his arms, there was something off about them. They looked thinner than they did previously, even compared to his scrawny arms. Even his hands looked tinier than they had before. Gone were his masculine arms, only strong, very well defined, but surprisingly womanly arms.

“What…? Surely this is just a side effect… right? Ugh…” Kelvin groaned and held his mid-section as it began to contort. The sides of the waist diminished, losing some of their mass, which went directly down to his thighs, causing them to balloon and grow further.

With not even a moment’s pause, the front of his stomach also began to vibrate, the soft flab instantly hardening. Visible muscles formed, even something comparable to a six pack, just… very pinched in. Like all of his fat was not vaporizing, and rather moving to other places. Despite more and more fat moving to the center of his chest, Kelvin smiled confidently.

“Bet you are jealous I got to have something like this now! I am sure you had to work long and hard to get even a quarter of the power I have now!”

Max screamed. "How can I be jealous when I'm watching a body contort and twist in ways it shouldn't!"

Snaps came from Kelvin's hips as they broadened, making Max reel at the sudden shift. Only a momentary discomfort flashed on Kelvin’s face at the change before his forced grin returned. He definitely looked like he was trying his best to look like he was in control of the situation, but then…

“Oh!”

Popping noises came from his legs as they shifted. His thighs visibly ballooned, straining his pants slightly as more of a curve appeared. Like with his arms, he prodded them with a grin and was met with more resistance every time he did so. It continued down his legs, and they thinned as the process continued. Like his thighs, they gained the same power running through his body despite their diminishing appearance. Pops came from his feet as they became daintier, becoming perfect, powerful, curvy legs.

All of the strength residing in Kelvin’s legs disappeared. He fell onto his butt, but the smirk he had remained.

“How the hell can you be so calm when your legs are changing now?!”

“The joy of seeing me kick your butt will more than make up for the changes to my body!”

“...I think you need to rethink your priorities if your body changing this much is enough to make you feel like you have won the lottery.”

Kelvin moaned, heat running through his body and centering on his hardening wood. Kelvin shimmied in place as the sides of his dick rubbed against his thighs. The pleasure he gained grew with every inch of his manhood receding into him. Right when the tip of his scrotum entered his body, he cooed in such a lusty voice it made Max’s privates harden. Both of his balls entered his body, making her squeal in delight. “Haaaaa~ I’ll admit, I didn’t think it would be quite this steamy, but it will make paying you back all the more sweeter.”

“What is your problem, dude?”

“Soon, I’ll be able to make you pay for all that you have done.”

“You just lost your dick and you are still focused on beating me up? The fuck is wrong with you, you damn weirdo!”

Kelvin gasped, sounding like a girl who had finally reached her climax. With a deep breath, she exhaled. She rose from where she sat, pushing up against the floor as if she were to stand. Like the rest of her body, her bottom cheeks filled with firmness as they grew. When it stopped tingling, Kelvin stood up and admired her rock-hard bum with a grin. Kelvin yelled. “That was damn good! I feel so powerful… so… Ah~”

Two decently sized lumps formed on her chest. They rapidly swelled, pushing the confines of her shirt. Button after button went flying off, exposing her dark mocha cleavage. The Bigger and bigger her bust got, the more they were pulling on her back as if sandbags had been thrown on her shoulders. Yet her enhanced back muscles compensated for the weight of her boobs. Kelvin’s new knockers finished growing when they had become an impressive F-cup, easily rivaling her noggin, which she also more than easily managed to carry around with her improved strength.

That's when she took a step forward, waves rippling through her body. Every step getting heavier than the last. Where at first she at least maintained the scrawny height she had before, now she was growing by a full centimeter every step. As her hair changed into an exotic green, she breached 1.7m. A dream came true a few steps later, as she finally got to the 1.8m mark like she had always dreamed of, making the small itch in her eyes as they shifted to a fiery red almost negligible. When she cracked her knuckles and her nails grew out and colored themself, she had already reached an astounding height of over 1.9m and was still growing.

Kelvin brushed her hair to the side with a savage grin. “Now then it is time, you get to see the power that I have gained from my hard work and research! Well… more like my sister's research, but who cares.”

Max gulped as Kelvin got closer, unable to tear his eyes away from her. The ripple of her bust and the power of Kelvin’s thighs made him wonder what it would be like to be between those thicc rippling thighs. And as the clearly over 2m tall gyaru girl stood in front of him menacingly, a weird thought crossed his mind.

‘Maybe this won’t be such a bad thing.’

SLAM!

“Holy crap! I am so horny again. Is Max in the area?” Kevia asked, looking around the lingerie store with hungry eyes.“This body is awful and way too horny all the time. Maaaaan… May I just go and let myself get…”

“Sis, you can't go for it right now. We have to buy you clothes, remember? You can’t keep walking around with my stuff, you know?” Clara replied, throwing a pair of panties at Kevias face.

“I knooooow. But I just need some relief. Can’t we do this shopping another time?” Kevia spoke, sitting herself down on a nearby sandbad in a very provocative manner.

“One: No. And Two: Who the heck is this Max you were talking about?”

“Oh! I told you about it! He is that hunky jock that bullied me all the time.”

“...and why are you calling for him if he is your bully…?”

“I mean, he might not be the best personality wise, but he can do nothing to stop me and he is an absolute beast in bed. I have decided that I like him now.” Kevia declared. “Doesn‘t mean I like being a horny bitch, but maaaan do I understand now why people want to fuck that guy so badly.”

“You can just decide that…? Also, what do you mean ‘he cant stop you’?”

“That boy has never dealt with a girl who is physically stronger than him. And taller. He just can’t handle me at all~ And that makes it sooooo fun~”

“I just… Didn‘t you say you hated being a…” Clara took a deep breath, then looked at Kevia once again. “Look, you might be a girl now because of my mishap, but that doesn't mean… Haa… I know I should have read the description where it said it was only for girls’ self defense and not for men at all, but now…”

“Oh! Max texted back!” Kevia declared, seemingly not even listening to her sister. Then she just hopped up and strutted towards the exit, not even bothering to button up her blouse. “I'll just take these leopard print panties and whatever else you feel like buying me. I’ll go and play a bit with my little bed toy~ Tata~”

“Wait! You can’t just…”

And there she went, leaving the store in confidence and leaving her sister behind. Kevia really had become too much for anyone to handle. Including Max. But he was special in the way that was the only one who couldn’t handle her in multiple different ways. But that would only come into play at night… or when she became really horny…

…like right now…
