Following the events of her most recent sleepover, Chelse found her innermost desires stirring. The mouse, normally shy and content with being a quiet kinkster, engaging in play only when she was completely safe, was finding herself more and more aroused and lost in her memories. She barely got away with the cleanup from her sleepover, having filled an entire trash can with cleaning supplies and things destroyed from her room, and yet, instead of her close encounter scaring her back into caution, she instead felt emboldened, a flicker of sexual deviance burning in her eyes. She began to think about what the other girls felt, what each of their kinks were like, and what it would be like to experience each for herself, maybe see what it was about them that set each girl over the edge. She began to think of what it would actually mean to try and recreate each experience, or to at least experience and perhaps combine their kinks.
	She firstly had to cross off things she was unable to recreate. She lacked Rhou's bladder capacity, the drake's acidic contents, and Calliope's ink. Her flow, while she did of course have one, was weeks away, and she knew from experience that, while she certainly enjoyed it, it was far more fun with Cath; she was a pretty light bleeder, whereas her girlfriend seemed to possess a rather frightful quantity. Biological limitations considered, she believed there was still enough material left with which to conduct "experiments."
	Cath and Cassie were easy; the first, being her girlfriend, had already shared her kinky side. "Speaking of which," Chelse thought, her paw drifting between her thighs as she sat at her desk, music playing as she daydreamed, "I'm in need of some of that." Cath was rough, but loving. She had a fondness of lingerie and the bondage aesthetic, although she wasn't particularly sadistic. The leather and ropes were more for show, and to help with keeping the timid mouse in compromising positions. She also loved to tease and humiliate Chelse, especially in subtle ways out in public, a form of foreplay that ensured Chelse would lose all inhibitions the moment they shared a private moment. The quiet little nerd could become quite the power bottom when she was needy, and she now caught herself distracted by the thought of pouncing on the vixen.
	Shaking herself from her fantasy, she withdrew her moist fingers from her pants, her clear honey oozing off her fingertips. Back to her list: Cassie shared her destruction fetish, so she was also written off. There was no need to experiment any further, especially with her closet still thinned out from her last experience.
	The second half of her list finally provided her the results she'd been looking for: new kinks to play with and try out. Rhou shared her love of pee play; it seemed they all did, but she also wore diapers. Chelse had never peed in a diaper. What would it feel like? It must feel good, she pondered, after all, wetting herself felt pretty good already, except Rhou often went hours without a change. She'd done it before, on hot days, the cool feeling had been nice. But Rhou wore diapers all the time. And the other things she did....How would she even buy diapers to play with? The idea of walking into a store made her blush. Once again, her fingers wandered, but she kept going. She would come back to look into diapers.
	Calliope, the last on her list, had a kink that Chelse was surprised to admit she'd never tried before. She distinctly remembered the ceph giving herself wedgies, ultimately ruining her panties by the time she'd left. She'd have to look through her panty drawer and find a pair she didn't mind ruining. After all, if she didn't like it, she could just resort to her tried-and-true method of pissing her panties and tearing them apart, right? That last thought made her emit a whimper, once again bringing her back to her bedroom, this time finding her thumb on her clit, rubbing in circles while her fingers teased in and out. Her wrist ached from straining against her tight jeans.
	Her list was complete, albeit short and, to her, a tad disappointing. She would have to add more later, but right now, she craved release. She decided to knock out Calliope's wedgie kink right away. Forcing herself to withdraw her paw once more, she hastily undid the fly on her pants, but didn't bother to peel them off. She just needed their pressure released. Gripping her panties as Calliope had hers, two fingers in each leg hole, straddling her pussy, she began to tug in little pulses, gently at first. She could feel the tension where the leg gathers dug into her, but rather than arouse her, they only itched in their current state. After a quick readjustment, however, she found herself spread, her panties slipping neatly into the crease of her folds, each tug teasing her clit, pulling back her hood and sending a small shock through her. She began to tug harder, the popping of elastic and stitches only adding to her arousal as she leaned back in her chair, her panties now stretching up to her belly button, her shirt lifted halfway. She wanted more. The feeling was incredible, but she couldn't seem to tug hard enough by herself, at least not at this angle. She could hear her panties crackle, but she wanted them to tear. She'd heard of it happening before; surely it couldn't be too hard, right? As her head leaned back, she saw the solution.
	Climbing from her chair, she crept over to her bed, nearly falling over as she finally decided to slip off her jeans while walking. Her bedpost would make a perfect hook; the beam extended several inches above her mattress, while the top was capped off with a round head which would prevent her panties from ripping from simply being pierced. She really hoped this would work the way it did in her head. Turning her back to the bed, she crouched slightly so her hips were level with the bed post, then fumbled with the waistband of her panties, until she felt it turn inside out, hooking around the top of the post. Her legs were already feeling the strain building of holding a slight squat, and she dropped to a full squat faster than she should have, a squeak and sharp inhale accompanied by more crackling of elastic filling the room as her panties were stretched nearly to her shoulders. Having left the gusset between her folds, the elastic now bit deep into her flesh, spreading her wide and pressing hard against her clit.
	She stayed there for what felt like forever, frozen in shock and pain. She could feel her heartbeat pulsing against the fabric, a slow, dull pleasure beginning to form. Eventually, she worked up the desperation to begin bouncing, slowly, grinding back against the tight fabric. Through it still stung, she began to enjoy the sensation, blushing a bit as her mind began to wander.
	"C-cute panties, n-nerd," she said softly, teasing herself as she playfully struggled against the fabric. "D-did your mom write your n-name on them? Mmmf!" She began to struggle harder, adjusting her feet so she now sank even closer to the ground, her underwear protesting louder with more rustling and crackling as the fabric stretched, the stitches threatening to give way. The bed post was nearly level with her head, and the underside of her tail now burned as well from being tugged by the rough elastic. "Ooh, I hear--haah--crackling. W-whaddyu think, little nerd, a-are we gonna make your panties rip~?" she began to sway her hips back and forth, grinding gently as her clit was pressed against, her hood tugged back with each stroke, slowly rubbing her off. She could now feel an additional warmth, the moisture of her nectar as she became even more aroused. She wanted them to rip, but not before she was done with them. She just had to last a little longer, just resist the aching in her legs, and the sharp biting that now also pleasured her.
	"N-no, please, d-don't rip these," she begged, bouncing harder than before. "I-I don't have any spares!" She leaned back against the bed, feeling herself closer than ever. Her panties were now level with the top of her head. She likely could have pulled them over, if she weren't so focused on ruining them. "I won't--people will--n-nooo~ haaaah~!" She was cut off by her own climax, finally overtaking her. Her heartbeat thundered in her ears as she subconsciously rocked against the tight fabric, the last vestiges of thought focused only on completing her fantasy, sitting all the way down on the floor with a thud as she dropped her full weight down. With a sharp pop, she heard and felt the bed post tear through her underwear, separating the elastic of her waistband from the cottony backside. In the midst of her orgasm, the pain faded; she only felt warmth and pleasure, and it began to fade as soon as she felt her panties tear. Whimpering in protest, she grabbed the front of her panties, tugging hard in sharp pulses to accompany the throbbing of her heart, each tug bringing another short "rip! rrrip!" as the hole widened, her waistband slowly tearing more and more off of her panties as she milked her orgasm as long as she could. Alas, her panties continued to tear until  the pressure was relieved, the waistband torn free enough to ride up the front of her body, leaving the rest of the shredded fabric bunched up underneath her, still flossing her pussy roughly.
	Panting roughly, she continued to tug on the moist fabric as she came down from her climax, now feeling tired and content, despite the burning sensation returning between her legs. The room seemed to swim before her as she struggled to stay awake, slowly coming to once more. Her panties were ruined; by her standards, they would need to be shredded completely before she finally tossed them, but they were certainly unwearable. The cottony fabric was stretched beyond repair, no longer returning to its intended position hugging her backside. The waistband was torn nearly all the way off, and was still wrapped around the bed post. The noise of the incident finally registered in her mind, and her eyes snapped open as they darted around the room, checking to make sure the door was closed. She listened intently, trying to sense whether anyone had heard the commotion of thuds, tears, and moans she had so recklessly let ring in her ears. She heard nothing. Cautiously, she came to the conclusion that she had gotten away with it.
	Standing back up on shaky legs, she pulled the elastic off from the edge of her bed, picking the wedgie out from between her legs only to close her thighs, feeling the ruined garment begin to fall right off of her. Blushing deeply, she held her underwear up as she walked slowly back to her desk, collapsing into her chair. She could certainly cross that off the list now, she thought, rubbing herself now more gently through the gusset, feeling now just how wet the fabric had gotten. She would have to remember these later, if they was any left by the time she got out of this chair.
