“Your Highness, I hope there aren’t any misunderstandings about our product. G-strings are made for women.” Luna stands up. “In fact, I’m wearing that same model right now.”
Luna turns her back to them, and the pair zero in on the shapely butt under her tight black dress.
“Look. Even though my dress is thin, you can’t see my panty lines.”
“Y-you’re right.”
Underwear lines are always visible under lightweight fabrics. There are girls who refuse to wear underwear to formal events to prevent them from showing.
But this G-string eliminates that problem. It can’t be detected under clothing.
“Are you really wearing it…?”
“Would you like to see?” Luna asks, slowly peeling up her dress to reveal her milky thighs.

Alexia yanks her skirt up to her waist and pulls her white pair down, letting them fall to her ankles before lifting one foot and then the other. After hanging them on a hook on the wall of the fitting room, she spreads out the G-string in front of her.
“It’s practically transparent…,” notes Iris, sounding utterly baffled.
“Seems pretty airy to me,” chirps Alexia, amused.
Alexia bends forward and raises her right foot, sliding the G-string up one leg and then the other. She tugs it up under her skirt and tilts her head curiously.
“It feels kinda weird…,” Alexia comments.
Iris is at a loss for words when she sees her sister hiking her skirt up.
“That’s…” Iris’s vision goes completely white.
“Your Highness. You have it on backward.”
“Oh, that explains it,” Alexia replies to Luna, leaving her dumbfounded sister be as she slips off the G-string and puts it on the right way.
“Ooh, it feels nice.”
“Yes, it’s made from our new prized fabric.”
Alexia kicks up, crouches down, and spreads her legs to test it out.
“Iris, look at this.”
That pulls Iris back to reality.
“Look.” Alexia jerks her skirt up to reveal a perfectly shaped butt that’s almost completely exposed.
Her delicate white skin glows in the light of the fitting room. Alexia playfully shimmies her waist, and her buttocks jiggle around.
“S-stop that shameful behavior right now!”
“And see? No visible panty lines,” adds Luna.
When Alexia lowers her skirt, Iris certainly can’t see them.
“And check out the front. It’s very cute.”
Alexia hikes up her skirt again, turning to Iris. The design is cute, but it’s…
“A-A-Alexia, it’s completely sheer…”
“It hides enough.”
Iris chants three times in her mind, It’s not enough, not enough, not enough.
