"I'm going to put my new panties on" Tiny Brother VS Big Sister chapter 8 by copier · original author: kentwolf

"I'm going to put my new panties on Mom, I'll be ready to go clothes shopping in a minute!" your sister said cheerfully, holding you close with a gleeful grin on her face. your mother smiled and just gathered the plates to wash up "alright sweetie. whenever your ready" she said casually as Christine carried you out of the room, almost skipping with joy as she carried you back to her room, the panties you were a part of swinging loosely in one hand, making you feel a bit queasy, though you couldn't get the pretty little smile off your face. it was so humiliating, disguised as Alice in Wonderland on your sisters new panties, unrecognized by your mother.

Christine tossed you onto the bed, you bounced face first off of her Cheshire Cat plushie she kept on her bed, you realized how well you blended in with all of her Alice in Wonderland items in her room. the plastic panties sliding down and flopped over, leaving you staring up at her Ceiling. you struggled to move, to squirm, break the polite smile or move your body in any way that you might be able to change position for next time your mother saw, unfortunately the tightly sealed and melted together plastic panties was so perfectly sealed it was as if this was your one and only shape. you couldn't budge at all. Christine had rarely ever had you trapped so perfectly except that time she wanted to impress her friends at school with a tattoo and used you.

you could hear Christine humming and rummaging through her wardrobe for something nice to wear. you heard her giggle a few times, you assumed that she was looking over at you when she laughed but as you were staring at her ceiling you couldn't tell for certain. finally you saw her face loom over you with a grin as big as her plushie's. "hi there Alice. hehe. time to put you on. then we can go try on girly things, wont that be fun?" she said her grin getting bigger as she picked you up and opened out the panties behind you. you were close to the ground and you felt her jerk as she stepped into the panties one leg at a time. you went shooting up as she pulled you up her bare legs and then the warmth of her body behind you as the panties fit snugly around her. she smoothed them out, running a hand over you as she did so.

you could see yourself as she faces the mirror. even to you it looked like you were a logo, fit perfectly between the "eat me" cake and "drink me " drink. you cursed Christine's eye for detail. you were forced to watch as she stepped into a cute turquoise mini-dress and slipped it up her legs and body, your vision being blocked out as it slipped in front of you. you could see the fabric slightly as light shone up from the bottom of her dress, but as you couldn't look down, you couldn't see anything. you heard her humming as she added to her outfit and then she began to walk, her legs making the plastic panties stretching and contorting as she walked, you could feel your back rub against her as she walked. your cheeks would be blushing even if your sister hadn't added blusher to them.

you heard your mother and sister chatting as they got ready to leave to go shopping with you in tow. your sister mentioning her new panties and how surprisingly comfortable they were. you felt the vibrations as they drove to the mall and had to listen to the endless "ums" and "ahs" and indecision on outfits as they walked about the shops. you knew they were probably gathering up dozens of clothing to try on. this was going to be a very long day for you. eventually light flooded into your vision again. when your eyes adjusted you were...
