This story begins with Cassie, in her workout gear, feeling bloated after an ab workout. She has to go and finds herself straining while pushing out turds, getting her asshole quite dirty. Despite this, she feels determined to get back to her exercise routine. Unbeknownst to her, the pushing has caused her to wipe ineffectively, smearing shit up her crack and across her cheek instead of cleaning it up properly.
Feeling frustrated by her constipation but eager for a proper workout, she pulls up her panties and shorts. Unaware of the skid marks she's left behind, she continues with her routine, showcasing her jiggly, flexing ass. As she steps into the shower, she notices the smell of shit and realizes she needs to clean her panties, kicking herself for not doing it properly before.
Despite being annoyed at herself, Cassie sets about cleaning her panties. The sight of her dirty underwear only serves to turn her on further, and she can't help but wonder what it would be like to leave them like that on purpose – for someone else to find and use. This thought arouses her, and she finds herself becoming more and more turned on as she cleans up the mess she's made.
As she finishes cleaning herself up, she can't help but feel a sense of pride mixed with shame. Pride because she's managed to workout despite the discomfort, and shame because of the mess she's left behind. But beneath it all, there's an undercurrent of excitement – the thrill of knowing that she's just taken a massive shit and left evidence of it for someone else to discover.
