TG Caption This: All Girls Tennis Club!

"You did what?" I stared at my friend Michael in disbelief. He had a habit of being an idiot but this took the cake AND the biscuit, as well as everything else in the pantry.
"I made a bet with Chloe and if I win then she has to go out with me." Michael replied, grinning as if he was proud of himself, he'd had a crush on the tennis captain for years, which I found to be no surprise, she was very beautiful and had a figure most would call a knockout, which was odd because I'd seen her parents and they were... plain, not ugly but just, plain; She was also known for flat out refusing anyone who asked her out, and that includes any of the girls, debunking the lesbian theory, however this was a dumb way to get her to go out with him though. "She just needs to be beaten at tennis is all." I rubbed the bridge of my nose with my fingers.
"Ok, let's go through this slowly." I motion for him to sit down. Once he's seated I continue. "You, who has never played tennis before in his life. Just challenged the captain of the tennis team, who has never lost a game since becoming captain, to a tennis match, and you bet on top of that. do you understand how bigger hole you've dug yourself?" I stare at him, waiting for his answer, he was still grinning, which wasn't a good sign.
"I never said I would be playing." I snapped.
"Nope, I'm not gonna do it."
"Why not?"
"You dug yourself into this mess, you dig yourself out, I'm not covering for you this time."
"c'mon, you're the only one who plays tennis and the only one who'll stand a chance against her, plus she's your friend so she'll go easy on you." His justification had a few major holes.
"I play casually and have never played in a proper tournament, I also am an acquaintance with her at best and, I know her well enough to know that she plays to win, always, no exceptions. Also, last time I played her, I lost miserably as in didn't win a single game miserably." I hoped he saw my point, but alas, he decided to abuse my weakness.
"You wont help out a friend for something as simple as this? I do believe you said you would help me with anything?" I had to cave in, I keep my promises.
".......... Fine, what's the date?" I hung my head in shame. "But this is the last time, you're not abusing that promise anymore in return for me doing this." I glared right into his green eyes to get my point across.
"10 am S-Sunday and deal." He stuttered, clearly trying not to be intimidated.
"k, I'll tell you the result Monday." I sighed, strolling out the library door, mentally preparing for whatever may happen, and the inevitable bruise I'll get on Sunday.

*Sunday*

I strolled to the tennis court at a brisk pace, might as well get this over with quickly, was running through my head. Hopefully Chloe's side of the bet would knock some sense into Michael. Ah, there's the courts, and the woman herself. Standing at six foot even, her athletic frame covered in white shorts, shoes, socks, t-shirt and cap with black hair tied in a ponytail with a red bobble and a fringe hanging just above her blue eyes; Chloe looked mighty surprised to see me. "Jake, what are you doing here?" she asked, a hint of worry in her voice.
"Michael apparently worked a loophole into your bet where he didn't have to play, and guilt tripped me into doing it instead." I emphasised the "apparently" with air quotes and a sarcastic tone to emphasise my frustration. "On the plus side, he's going to stop guilt tripping me after this so, I get something out of it I guess." I added nonchalantly. Cloe seemed unusually flustered, she can't be worried I'm gong to beat her, we both know that wont happen.
"W-well. Let's get going shall we?" She turned around and led me onto the court. I can't help but feel exhilarated for this match, I just want one game and I'll be fine.

Well, this is lame. I'm two one up, and I didn't even have to try. I decided to play even worse than usual, she's going easy and I don't like it. After a few bad shots and bringing the score to 2-2 she started to take note of my shenanigans. "You're doing this on purpose!" She snapped. I snapped back.
"So are you, play properly." This shook her a bit.
"Y-you could tell?"
"Yes, now let's go, don't worry about the end result and just do it." That seemed to have gotten through to her, she mumbled something under her breath and served... an ace.
"How's that for proper?" her smirk victoriously prominent.
"Much better, let's roll."

3-6, she won, I got one game on her at least, well, when she was playing properly. "Well, you win." I sighed, feeling light headed. I took a swig of my juice to help. "Good game though."
"Good game to you too... but." her face had a guilty, but strangely happy look to it.
"But what?" I inquire.
"Did you know what my part of the bet was?"
"No, I figured it would be funnier to find out when Michael had to do it." I grinned.
She sighed, not a sad sigh, but a "That's just like you" sigh.
"My part of the bet was that he'd become my protégé and partner in the next girls tournament." That brought a snicker out of me. The image of him cross-dressing was too good. It would definitely knock him down a peg or too. "However." That got my attention. "I used a spell that would turn the looser of the match into a girl."
"Wait, spell?"
"You don't think I look this good naturally right?" She winked playfully.
"I just figured you got it from your grandparents or something." I shrugged, magic seemed just too fantastical a concept to consider.
"Yeah well, this..." She gestured to her body. "...Was an accident, I just read the spell for kicks."
"So what have you done?" I asked. whatever it was can't be good, why would she be telling me this otherwise.
"Simple. I put up a spell that would turn my opponent into a girl if they lost." She said cheerily.
"Oh, if that's all then..." Realisation hit as I snapped my head at her. "...Wait, WHAT!?" My voice cracked heavily from that outburst, almost too heavily. I stared at her in disbelief.
"Yup, and..." She slinked up with a mischievous glint in her eye and a smirk gracing her lips. "... You're already halfway though." She whispered into my ear. the words took a second to sink, but once they had it hit me like a tennis ball to the back of the head (which I've experienced way to often).

All at once I felt a new weight on my chest and rear end, noticed the world growing around me until my eyes were at chest level to Chloe, and the feeling of my entire body thinning, slenderising and becoming rather fragile, what with the lack of any muscle gain to match that of a proper tennis player. I took a second to notice the hair in my eyes, I'd just had it trimmed so it shouldn't be doing that, but there it was, and blue at that. I felt uncomfortable for a moment before I noticed no fabric between my thighs a quick look showed that my Black tracksuit bottoms had become a pink skirt, a pink skirt that only just covered my butt, my black socks had turned white, my shoes had shrunken to fit my feet and my Casual T shirt was currently reshaping as well, to the same plain pink as the skirt. Once everything was over I followed instinct and decided to check if she.... she had, I was a girl now, through and through. It wasn't long before I felt a pair of arms pull me into a hug, and my face into, what I believe is called, marshmallow hell. "Oh, you turned out sooooooooo cute." I could hear Chloe squeal. I would have complained, if my face wasn't in a position where I could hardly get the air to breath let alone talk. So I decided to try and flail instead, that didn't work because now I was even weaker than before and she had a strong grip. I was eventually let go and quickly started gulping air greedily.

After a few seconds. I noticed Chloe staring at me, with a sort of wistful expression in her eyes. "What?" I gasped. I wasn't in the mood and she was acting weird.
"Oh, nothing, just thinking that we're going to be around each other a lot. And I don't just mean tennis training." Chloe said in a low tone. She was trying to be seductive, even I knew that. "I mean, you're going to need help with being a girl as well, and as it's my fault, I might as well do it." She grinned, She had gotten close without me noticing.
"U-umm, ok." I was too flustered to say anything else. The way she was acting was familiar somehow. She looked annoyed and pulled out a pair of glasses from her skirt pocket. They were the old fashioned nerd glasses with big round lenses, but the lenses had a heart scratched into them along with the letters "J" and "C" inside it. My eyes bugged out as I put the pieces together. As if guessing my thoughts, Chloe smirked again and said in a low, seductive tone. "You get it now, Jackie?" Only one person has ever called me that.
"B-but how d-did, w-what did, why di..." I was cut off by her kissing me. It was strange but I couldn't think of anything except "Her lips taste of apple". I guess that's just something that happens when you're kissed whilst having a slight panic attack.

The kiss was over quickly and I felt something being pulled over my head. I went to touch it to find a sweat band under my fringe, with two smaller ones on my wrists. "C'mon, we've got to train for the tournament." She whispered before rushing to the other side of the court. I sighed as I realised what had happened, and what I'd gotten myself into but I got into a ready position anyway. She hit the ball right between my legs, the breeze flipping up my skirt. I quickly attempted to pull it down but the wind stayed, and I could hear the whistles of a few guys who were passing by. I glared at Chloe who just smirked slyly and mouthed something at me. It took a while but I figured it out and panicked when the wind got stronger. "You. Are. Mine."
