Serena never thought a wedgie would be her kink, but now she needs that humiliation any time she wants to cum. It got worse when her girlfriend started teasing her about it, at first she was a little upset, but then she became turned on just from the teasing. God, what a slut! When her girlfriend came home with a package in her hand she didn't think anything of it, but then she was told she needs to shower and be ready on the bed.
"Ready for what?"
"We're going to go out, but I get to pick your outfit."
Only slightly concerned, Serena showered and sat naked on the bed, waiting for Viv to pick out some clothes.
Viv sashayed in and Serena almost gasped, she was wearing such a slutty outfit and it was turning her on immediately. She had a short skirt, tight top, and she was showing the most cleavage Serena had seen besides when she was shirtless.
"You haven't even seen the best part," Viv said, lifting up a leg and powerfully placing her heel on Serena's thigh. This small move was enough to show off her clean-shaven pussy. Viv smiled at Serena's longing gaze.
"Good enough to eat, huh?"
Serena gave Viv her best doe eyes, "oh no, bitch. We're going out first."
"Plus, that's not the best part."
"What else is there?"
Now Serena got really excited, maybe Viv was also wearing a butt plug? And if they went dancing she'd have to dance in it too, constantly feeling that pressure inside of her...
When Viv dropped a plastic package in her lap, Serena was confused, to say the least.
Serena ripped apart the plastic to reveal... "A chastity belt?" It didn't look like what she had seen before but it was definitely part metal. It had a rubber-lined metal for the waistband, a locking mechanism, and for the pussy area it was a small piece of spandex like a thong. It wouldn't make accessing the genitals too hard.
"Nope," Viv had a vicious grin now. "A wedgie belt."
Serena's face felt like a volcano as she suddenly realized what this meant. Viv would want her to put this on and wear it out. Locked in with a wedgie while they were at a restaurant or club, the tight fabric digging into her pussy and ass.
"Put it on now, we don't have a lot of time. Step into it and I'll lock it. Oh, but first..."
Viv turned around and grabbed a bottle off their dresser. Serena didn't have time to read the label before Viv tipped and shook it over the thong part, small particles fell out like it was salt. "Ew, what's that."
"Hm, deodorizer. Now, you're running out of time."
Serena was too distracted to ask more questions. Since she was already naked she did as Viv told her, she stepped into the thong and turned around to show Viv the lockable back, which already had a key in it.
"Deep breaths, I need to pull it up to lock it."
Serena bent over the bedside and took a deep breath, Viv started pulling and Serena let out a gasp despite her preparation. Her ass immediately was burning as most of the stretch came from that fabric. Viv dug a finger into Serena's pussy to grab some more fabric from the front and then pulled even harder on the metal waistband, causing Serena's vagina and ass to ache. With two strong arms, Viv was able to hold the waistband together and lock it.
Serena didn't move and started taking more deep breaths while Viv stepped back and admired Serena's ass.
