Bethany steps out of her dorm room and looks down both ways of the hallway, trying to see if anyone would see her scratch her butt while she walked to class. After not seeing anyone, she goes for it again. You are once more forcefully rubbed against the inside of her butt cheeks, as she tries to ease the now unbearable itch.
"There must be some dried detergent or something down there, this itch isn't normal", Bethany mutters to herself. A sudden decision makes her go back inside and close the door behind her. She quickly goes into her room and takes off her leggings, then pulls you down to her ankles. You were in so deep that she struggles to peel you off of her crack, but once you're on the floor, she steps out of you and picks you up in order to inspect you.
Seconds ago, you were encased in complete darkness, but now, even though the stink of her ass that has been rubbed into you isn't gone, you have slightly fresher air and you can see prettier part of Bethany, her huge eyes, searching every millimeter of your face for clues.
"Is this... is this itching powder?" She says, trying her best to scratch herself still without plunging her fingers into her butt crack. "This must have been Robin, that bitch!"
You're both impressed with her deductive skills and disappointed with the fact that she was no longer wearing you. "Knock knock!" a high pitched voice, followed by a mischievous giggle, makes its way from the front door to Bethany's room. It's Robin, who had been eavesdropping on Bethany to see how she reacted to the prank.
"ROBIN, YOU BITCH!" Screams Bethany, storming out of her room to confront her friend. She opens the door to see a very amused redhead with her hand over her mouth, laughing uncontrollably. "Girl, if you keep scratching yourself like that you're going to burn a hole through your panties!" She says, before bursting into more laughter.
Bethany, who is no stranger to Robin's pranks, just breathes deeply and talks to her friend. "Look, that kind of prank isn't funny, Robin, you've gone too far. Now I have to shower again and my ass itches so bad! Does this thing wash away easily?"
After explaining how to wash the powder off, Robin sits down on the couch and waits for her friend to shower and change her clothes. You're still in Bethany's hand as she walks towards her room. Suddenly, though, she turns around, carefully crumples you into a small ball and tosses you at Robin. You fly through the room and land beside the redhead, who flinches slightly at the flying pair of itching powder-laced panties. After making sure to grab a part of you that doesn't have powder on it, she pinches you and lifts you up to her face, with slight disgust on her face. "So, you're one of Bethany's unfortunate panties, huh? Guess you've already been through hell more than once but today has had to be so bad!" she says, as if she were talking to a living being. For a moment, you think she knows that you're alive, but the girl just giggles and sets you back down beside her.
"Real funny" says Bethany, clearly fed up with Robin's nonsense. "You can keep those, by the way, I'm never wearing those again, not after what you've done to them" she adds, before closing the door to the bathroom.
Robin looks at you after hearing her friend, then slightly puckers her lips and shrugs, then pinches you and lifts you up again to look at you. "You sure?" she yells at her friend, who's already started the shower. "Mmhm!" answers Bethany, sealing your fate as a new girl's pair of panties. "I mean, they are kinda cute. A good wash and all the powder should be gone", she thinks aloud.
