Yes, but... (Accidental wedgie)

As she makes her way down the bus, she starts feeling a chill on her butt, however just assumes it's her cheeks going numb due to the consistent pressure on them. After making her way off the bus onto the ground, she immediately jolts back on impulse as a frisbee flies right past her. "Sorry" The guy who threw it shouts over to her before chasing after the frisbee. Unfortunately for Kim, she was pushed back into the bus at just the wrong moment. Leaning back with her feet still on the curb, the door closes right when she hits it. She's instantly filled with two sensations. First is the cold touch of the clear door on her bare ass. She realizes that her skirt must have flipped itself up while she was shifting around in her seat. And secondly, her panties suddenly feel taught, getting pressed into her sensitive areas yet again. "EEEP!" Another squeal escapes her lips as she realizes that the back of her panties have been caught in the door. With her leaning back, her feet struggle to stand on the curb. Her hands shoot to her crotch which is thankfully covered by her skirt. Her excitement from before enters her mind again with the addition of fear. She tries her best to suppress her quiet moans as her panties are being pulled taught against her small pussy and tight ass. She was also grateful that the bus driver hasn't left yet, however another realization hits her. If her feet give way to the curb, gravity might take an even bigger toll on her ass. Extending her body the best she can, her legs begin to tremble. Her feet now on her tippy toes. The consistent pull up her crotch, threatening to split her in two, throws her hormones into a craze. With her body's senses already heightened from masturbating, her body thirsts for a relief she hopes doesn't come. She feels another moan coming on as they get harder and harder to keep in. Her hands shoot up to cover her mouth, but in the process, her feet start slipping. "Oh, God! Please, no! Please!" Her one foot slips, leaving the tips of her other shoe being her last thread as it shakes with weakness. Losing it's strength too, her foot gives way and Kim drops, getting caught only by her panties. "Mmmmmm!!!" Kim does her best to suppress her moans. The fabric now skyrockets into her ass and pussy, feeling deeper than she knew possible. Kim starts hanging here against the bus with her panties, unbeknownst to anyone who might see her due to her skirt, is shooting up her ass, a thin line that is violating her in public. The fabric digs deeper and without mercy as she starts feeling more around and more wet. Her eyes close shut as she forces her hands to her mouth to suppress her moans. "Mmmmmm.... mmm...... mmMhmmm." A quiet popping noise can be heard from behind her, but she's too preoccupied by her slowly reaching her climax to notice. In desperation, she tries to pull at the fabric that's pressing into her pussy from over her skirt, however that appears to be a challenge with grasping what is now such a thin line of panties. Suddenly, more popping sounds can be heard before the tension stops and Kim falls to the ground. With the suddenness of what just happened, it takes her a moment to reorient herself. She feels some tension now pulling on her stomach. As she assessed the situation, she realizes that her panties must have snapped in the back. In the process of them breaking, the waistband seems to have pushed her skirt up as well up to her stomach. She realizes that she giving any onlookers a show, or she would if anyone had noticed. She looks down at her bare and shaven pussy, visible to the world. Her hands immediately cover her soft and intimate area, feeling her wet juices down there as well. Looking around, there doesn't seem to be many people around and, somehow, no one is looking her way. Some student are walking around campus off in the distance while others seem to be sitting on benches close by, but too engulfed in their phones or conversations to have noticed. Even the guy with the frisbee seems to be long gone. Kim sighs with relief and looks back at the door.
