Not exactly.

Your little hands lift the tiny skirt slowly revealing the little triangle of white cloth of your panties. “Huh.” You say quietly and probe deeper, pulling down the little g string your cock flops over the fabric. “No way.” Taking it in your soft small hands it looks pretty good sized, but as you are tiny you can't be sure. Stroking it you see it grow till you are pretty sure it is about 7” long. A hairless sack just peaks over the top of the little g string as well. Looking in the mirror you can't help but get hard looking at a hot little slut stroking her long shaft. “This is so intense. No fucking way. This can't be real can it?” Staring at the mirror in disbelief you have to see if the tits are really real and untie the top letting it fall open. As soon as the top falls open you have to smile at the perky perfect deeply tanned tits standing at attention on your chest. They aren't huge, but very sexy B cups with nice suckable nipples with little silver rings piercing them. The feeling of fondling and pinching your nipple while stroking your sexy cock, all while looking in the mirror sends a wave of pleasure ripping through your body, and before you know it you are back on the bench, feet up, leaning back, and furiously jacking off. “Oh fuck I am so hot.” You blurt out as you send a stream of cum across the little stall and splat against the mirror. Grabbing your shirt you wipe off your cock and milk yourself till it is nice and clean. “This is intense. Magic clothes, bad ass. So I guess I have my costume for the party.” You say with a laugh and strip. As the last speck hits the floor you stand naked in the mirror and are completely turned on by the sexy long black haired little slut staring back at you. “Oh wow so it was the makeup then.” You say with a smile and grab the closest thing to a towel, the skirt and start rubbing off your face. A little while later it becomes pretty obvious you are going to need water if you are going to get it all off. But now that you have made a mess of your clothes with cum and makeup all over the little costume, you aren't sure exactly what you are supposed to do and just go back to work, using the stockings to dig in and wipe as much off as you can. “Fuck this, I need water.” You say finally giving up. Looking around you know the only place to find water is the public bathrooms, unless there is a private one in the store room. In either case you would have to leave the safety of the little dressing room. Looking over the pile of now messed clothes you realize you are going to have to go out of the dressing room and find something else to wear if you are going to go and get some water to wash all of this off. Or better yet go find some makeup remover at another store. “Well shit.” You say holding up your pants up to your new 90 lbs body. “Ya, ok so I guess I swipe something, unless that bitch outside can help?” You think out loud.
