"It feels so real, like it's my skin... I wasn't expecting that, sorry about the buttons." you said ashamed of your reaction while borrowing your uncle's costume.
"Yeah, please try not to ruin things while you're here, but thankfully, a few buttons are easy enough to fix."
Your hand was busy examining the strange new sensation of having pec muscle. "This is freaking me out, it feels so real. I... I want to get out of this and back to myself." You mumbled.
Uncle Jack gave you a look of scrutinizing analysis before it was replaced by a compassionate chuckle, "Of course, simply remove the clothing and the body suit will separate. I'll just be over here." He strode away as you turned to a dark corner to undress.
Removing the articles of clothing was easy enough, pulling off the grey winter beanie, removing the shirt the rest of the way, the nearly comically large boots, the jeans and belt, large socks, and with a shy glance behind you to ensure Uncle Jack was giving you privacy, the boxers...
You were naked groping at your collar bone... the flap should be somewhere around here... Back at the mirror you cringed as you looked at yourself. Your torso was massive and ripped, yes, but your arms and legs were that of an untrained teen and without the flannel shirt covering the jarring transition, you just looked bad.
Giving up on the torso, you tried to remove the penile attachment but stopped after a few seconds as you began to become erect almost immediately. You quickly slip on your underwear and pants, realizing for the first time that your old clothes are less equipped to handle your new erections than you imagined.
"Uncle Jack, the costume isn't coming off..." you said as you secured your pants uncomfortably... returning to and presenting your unclothed torso to him a few seconds later.
"That's... just... get the packaging, this is silliness."
You retrieved the packaging, presenting it to your uncle with little more than irritation at the situation. Your uncle's care to detail enabling the costume to transmit sensory data is great for prosthetics but not what you want from a temporary costume... and inability to remove it from your frame is bringing you closer to claustrophobia than you'd care to admit...
"This is a cursed item! Why did you wear it!?!?!?? How, did you wear it!!!!??????" Your uncle became frantic before suddenly retreating to his mind leaving you with innumerable questions.
"Ha ha Uncle. You're about 7 years too late to fool me with talk about magic... What are you getting at Uncle Jack? You told me to pick something out and I did, I didn't notice..." your answer seemed to fall on deaf ears. He began a string of gibberish which somehow reverberated throughout the building filled with cloth...
"All my wards stand so how can this be?"
How can... what is that!" you finally took your eyes off your uncle to see that 90% of the items in the store, including the walls, and your chest, were glowing with a multitude of runes in varying colors.
With a frown Jack turned to you, closely peering at the markings across your torso as he muttered something and waved his hand over your chest... His brow furrowed as his eyes moved back and forth across meaning only he could gather... "Okay, this item was meant to go to an ADULT woman buying a costume for the man she wanted to settle down with. The costume will grant a nice physique and endowment permanently, but well, you should probably just focus on getting the suit removed as quick as you can."
You looked at your uncle quizzically blushing but concerned. "What the hell does that mean?"
"If you don't get that suit off..." He looked at your torso again to be sure, "the next 5-7 days are probably going to get a bit crazy." He sighed trying to figure out how to word things, "To the right person a 'curse' isn't a bad thing, it's just magic very focused on one very particular outcome. With that focus comes power. The power needed to alter reality. As it progresses it will change your mind, body, and life. The curse part comes in when you don't want that outcome but every move inevitably brings you closer to that end. This suit will force your life into a specific box... Imagine a man wants to become a great business man and he gets a suit that will turn him into that... not a curse right? Now imagine an artist who wants to live a carefree life, and wears that suit to a friend's wedding only to find he is suddenly working an office job and becoming a business obsessed corporate man who will only relax a yearly vacation at a time. That's a curse... for example."
"Oh, So what should I be doing then? Am I going to turn into a business man?" You were acutely aware he described an example but didn't confirm the 'end' you were hurdling towards in any detail despite describing it as being focused...
"You need to show the suit you are confident and ready to tackle everything life has to offer you, showing the suit you don't need it."
"I'm 16, I'm not a genius, and I am wildly unprepared for what life has to offer me. So now what do I do?"
Uncle Jack sighed heavily as he rubbed his temples, "Figure out something you want, and go after it without letting fear stop you from trying..."
"You expect me to go out in public, like this? I look like someone who only did chest exercises since they were 2 and somehow didn't even hit my arms in the process!"
"Give it an hour or two, the costume will continue to adjust... you. The longer you wear it, the more prior changes become permanent. But I need to figure out how this was possible in the first place." Uncle Jack turned to leave.
"Wait, Uncle Jack... Maybe I'll like what it has in store for me, I mean, I don't mind the endowment and if I'm going to be buffer... What is it trying to turn me into?"
Jack hesitated, possibly afraid to terrify me if I couldn't get it removed, possibly afraid I'd like it and not try to remove it... "It's making you into ... ... ... ... ..., but you aren't my main concern. If I can't figure out how this happened, I'll be unable to open the shop tomorrow, as other people may get themselves cursed."
