Little Missa is a real hell raiser, her mom dropped her off at her Auntie Lana's house for the day. Missa is sitting on the sofa, her little body making the sofa look so huge. She plays with her toys carelessly throwing her little cars about. Auntie Lana is an uptight but so sexy scientist. She rolls her eyes at Missa's ruckus, and tries to ignore her while she works on her human genetic regression formula on the computer. Little Missa looks at Auntie Lana and tries to get her attention. She tosses her shoe at Auntie, missing her and hitting a nearby mirror, shattering it to pieces! "Missa!" Lana turns to scold her, Missa sweetly explains, "Auntie Lana, I really love staying over your house." Auntie Lana tries to quiet her to continue with her project. Missa tosses her second shoe at Auntie, "I'm thiiirrrssssttyyy." Auntie ignores her, bites her lip, and exits the room to look for her second formula to be put under the microscope for charting. Missa grabs the growth hormone in the vial and takes it. Missa feels a little funny, a little dizzy, oh my.. Auntie looks at Missa and sees that she took it completely. "That's IT!" Auntie grabs Missa by the hand and pulls her over her lap. *Spank, spank, spank!* Missa's little bum gets bright red, her eyes water. "I'm sowwwy, so sowwy, noooooo!" Auntie spanks her little tushy until it is cherry red, and then tells Missa to get in the shower and go to bed. Missa sneaks the reduction formula into Auntie's coffee before she leaves. It was so easy to do Auntie is so focused on her work. Missa giggles and walks to the bathroom. She looks at her hands, her body, her dress looks shorter, is it possible that she is taller? She gets into the shower and starts to clean herself, she bumps into her chest, what the.. "boobies?! Oh, my! I have boobies!" She is so excited about her boobies, squeezes them, and tweaks her new, womanly nipples." She notices hairs on her kee-kee, she plucks one out and inspects it. "Woooah!" She has to tell someone, and her strict, grumpy Auntie is the only one in the house! She pulls her hair into the towel and skips to the living room. "Auntie, look at me. I look like such s big girl!" She twirls to show off every inch of her new womanly body. Auntie is shocked, angry at Missa, but so pleased that her formula worked. She considers punishing Missa again, but no time.. she needs to get her back to her little size before her sister sees what she did to her daughter! "Oh God, where is my reduction formula." Auntie Lana looks frantically around the desk for the tiny vial. Auntie Lana takes a sip of her coffee, she knows this is going to be a long night. Missa picks up the empty vial and shows it to her. "MISSA!" It's all gone, did you take it already?!" Missa puts her crossed fingers behind her back. "Mmm-hmmm," she lies. Auntie Lana takes another sip of her coffee. How is she going to recreate that formula in time, she wonders. If she can't get Little Missa back to her 3 foot tall size, then how furious will her mother be, lugging around a disobedient 5'6 little one trapped in a woman's body. She sips the coffee again, Missa giggles at her incessantly. "STOP IT! I'm trying to think," she scolds Missa. Her body shrinks inside of her professional, frumpy black dress. The sleeve falls off, Auntie Lana gasps! Auntie Lana shrinks, shrinks down until she is about the size that Missa was originally, three feet tall! Auntie Lana is furious. "YOU are getting spanked again, you naughty little.." Missa interrupts, "Oh no, Auntie, it is YOU who is getting spanked. You're so little, you can't run from meeeee!" Missa grabs Auntie and throws her over her knee, "whap, whap," she spanks her Auntie's perfect bubble butt. She stops when she looks close at Auntie's private parts, she spreads Auntie's ass cheeks apart exposing her pussy and ass. "Oh my! Your lady parts look so different than mine." She then continues to spank Auntie, with her little girl mind, she scolds her Auntie, she says "Stand in the corner! You need to think about what a baaaad Auntie you have been." Little Missa walks out and into Auntie's bedroom. She sees some lingerie. She is not quite sure how to put on unusual panties with no tushie backs, just a string for the back?! How strange, so different! She is a quick learner, she puts on the thong, string in the back, and models her new grow up body inside of it. She puts on a neglige as well, and is shocked at how womanlike she looks. She goes to show Auntie. Watch the story unfold
