Frankie Foster gleefully ran into her room, quickly shutting and locking her door as she tossed a rather filled plastic bag onto her bed. The foster home was empty for the annual beach trip, but she didn’t want to chance anything. She never really got time to herself, and usually when she did she used it to be with friends, but today was just for her.
“I can’t believe I waited this long to do this,” Frankie smiled to herself as she grabbed the bag and flipped it upside down, allowing a rather hefty load of undergarments to flow out into a small pile.
They were various colors, styles, and materials all bunched together with random tags and strings straying from the pile. Lace, cotton, even silk all poked through the crowd. Frankie bit her lower lip unconsciously in excitement as she threw off her green jacket.
The young woman could not look away from her haul as she bent over sliding her skirt off and revealing to her room the plain grey cotton panties she wore. They were far from sexy, but they were very representative of Frankie’s every day. Full coverage, snug but not quite tight, and much more comfortable than visually appealing.
“Ugh, I look like a grandma.” Frankie scoffed to herself as she turned partially around to look at her backside in the plain panties reflected in her room’s full length mirror.
She had always been so busy with school and work at the Foster home that she never really had much time to think about things as trivial as her underwear. That is until it hit her like a ton of bricks that she was in her twenties and she didn’t own any underwear that could really be considered “sexy”.
She filled them well and even with the unflattering dull panties she could appreciate her rather toned legs and butt. But her self-admiration was momentary as she turned back towards the new undergarments. She didn’t even bother removing her shirt she was so excited to get to the panties.
“Which one first?” Frankie asked her self as she began to spread the panty pile across her bed. The first pair to catch her eyes was a miniscule blue G-string. It was a beautiful royal blue, but was intimidating because of its size. The string in the back was so thin she could practically floss her teeth with it.
“Let start something a bit bigger first,” Frankie relented setting the g-string aside, not quite ready to make such a big jump. Instead she turned her attention to a light green set of nylon cheekies.
She figured that cheekies probably didn’t feel too different from her regular old bikini cut and might just show off a little more of her figure. In one fluid motion she slipped her grey panties right off onto the floor and excitedly slid her first foot into the leg hole of her new cheekies.
As she slid them up her legs she could feel the nylon stretch a bit as it went higher and higher up her body. The cheeky panties finally reached over her butt and at first they felt the same as any old pair of panties, until she gave one last little tug to make sure they were set on her hips, and the bottom of the panties slid right between her cheeks.
It caught Frankie off guard but wasn’t altogether unpleasant. It didn’t feel quite like a wedgie, but it definitely felt different than full backs. She was consciously aware there was fabric between her lower butt cheeks, but the feeling was very passive and she could absolutely get use to it.
“Not bad,” Frankie said staring down at her crotch, snuggly wrapped by the panties, “I wonder how the…”
She began before she stopped mid-sentence looking at her butt in the mirror. It was absolute night and day between the cheekies and her regular panties despite the fact they initially looked so similar. That ever so slight wedge of fabric showed off the half moon of her lower butt cheeks spectacularly. She could actually see and appreciate the curves of her own rear end. Looking at that little bit of undercheek Frankie couldn’t help but straighten her legs, bend forward slightly, and pop her butt out.
“I can’t believe I had worn those boring old things for so long,” She scoffed looking down at her grey panties for a moment before turning her attention back to the mirror, “And if these look this good…”
She turned her eyes back towards the bed and spotted a new target. Feeling empowered by how good she looked with just a small amount of backside showing, she wondered how a bit more might appear.
She grabbed ahold of a red lace thong that was sure to be a new experience. It had a decently thick waist band with a floral pattern, but the crotch was fairly sheer and the band in the back was maybe an inch thick.
“I tried thongs once before,” Frankie said to herself as she slid the cheeky panties down, the small bit of wedged fabric sticking between her butt for just a moment before a small tugged pulled them out, “I don’t really remember liking them…but who knows.”
The lace felt far different than her typical cotton, it didn’t feel smooth or as gentle as she slid the thong up her legs. Frankie held her breath for a moment as she reached the bottom of her ass, knowing that the strap was about to go right in. She braced her self and pulled the waistband up, the string going right up too.
“Wedge-ie.” Frankie said to herself as she set the waistband slightly high on her hips, the string doing exactly what she thought.
Unlike the cheeky which was barely noticeable, Frankie was fully aware there was something between her butt cheeks. She could feel the small band riding all the way. Half tempted to pull at the thong to release the wedgie, she fought it as she looked down at the front. Admittedly it was pretty flattering up front. The front was smaller than most panties, and the slight see through lace provided just the faintest of glimpses at her mons.
“Here it comes,” Frankie grimaced as she slowly turned around, her legs held together as she flexed her glutes in an unintended response to the wedgie.
Then her entire world changed.
Frankie never particularly saw herself as sexy, and she never gave her own butt too much thought. She knew she didn’t have a particularly plump rear end, but she also knew it wasn’t flat, and she was okay with that. But as she turned around to see her ass framed in that lace thong, she was stunned with how amazing it looked.
The thong’s string started off at the waistband, providing proof she wasn’t just wearing a belt, but as it reached down it disappeared. The string couldn’t even be seen as she held her legs together, her butt free to show off its roundness. Her constant activity made it tight, but her admitted sweet tooth provided just enough plumpness that created an apple shape further highlighted by her thin waist.
“I…I can’t believe how good it looks,” She smiled from ear to ear as she bent forward, catching just a glimpse of her mound between the gap of her thighs.
She couldn’t help but lift one leg up onto her bed, bending forward to really accentuate her ass, catching just a glimpse of the thong between her lower ass as she did so. She was so proud of how she looked, she could still feel the wedgie like sensation, but it only added to how sexy she felt. The appearance alongside the sensation combined made her feel something extra…aroused. She could feel the warmth starting up from between her legs as she continued to admire her sexy ass.
“If these look this good…” She said once again biting her lower lip as her attention turned to the tiny G-string, “it stands to reason…”
It took no time at all before the lacey thong was being pulled down, turning itself inside out as it clung between Frankie’s glutes. Rather than let the thong fall to the floor she kicked it into her hand with one foot, setting it on the bed as she grabbed that blue g-string.
She held the string up before her face, admiring just how small it really was. She was undeniably aroused, her nipples beginning to harden and poke ever so slightly through her white shirt.
No time was wasted as her legs made their way into the new panties, and in one smooth pull gliding right between her legs, that string was on.
Frankie made a point to accentuate her walk as she approached the mirror, popping her hips on which the string waistband lied. She could feel it give her a wedgie with each step but she liked it, it added to the experience. Just as she began to turn around her moment of bliss was interrupted by an abrupt knock on her door.
“Frankie are you in there?” The familiar voice of Mac asked as the boy knocked on the door.
