Marina was sitting on the edge of her bathtub, her knees pulled up to her chest as she rocked back and forth. Her delicate fingers worked together, rubbing against one another as she closed her eyes and took a deep breath. She was just eighteen years old, recently graduated from high school and on the cusp of adulthood. Her body was still young and untouched, but her mind was racing with thoughts of the dirty things she'd been learning about lately.
As she bent over to grab a bar of soap from the side of the tub, her smell hit her first. It was a rich, earthy scent that made her gag a little bit. She knew it was her own shit because she'd been avoiding the bathroom all day. She hated using public toilets, preferring instead to hold it in until she could get home to her own private bathroom. That meant that sometimes, by the time she got around to going, her bowels were full to bursting.
Gingerly, she slid one finger inside herself and began to massage her entrance, feeling the tightness of her rectum as she moved. She bit her lip and moaned softly, her breath coming in short, quick pants. Her fingers pressed deeper inside herself and she squeezed her eyes shut as she felt the first twinges of pleasure. She began to move a bit faster, her other hand finding its way down to her lower region.
She spread her cheeks apart, revealing the piece of toilet paper that was sticking out from her asshole. It wasn't much, but it was evidence of her recent bowel movement. She worked herself up into a frenzy, her breath coming in pants and her body shaking with every passing moment. Her fingers dug into her slit, her nails digging into her sensitive flesh as she tried to find the spot that would send her over the edge.
And then, she felt it. A sharp pain as her body released itself onto the toilet paper, a hot wave of shame washing over her as she finally relieved herself. She cried out, her voice muffled by the glorious feeling of release. Her body convulsed, her fingers digging harder into her flesh as she continued to masturbate. The feeling was overwhelming, but in the best way possible.
When she finally came down from her high, she let out a long, shaky breath. She felt sticky and gross, but also thrilled by the experience she'd just had. Tentatively, she reached between her legs, feeling the sticky mess that was her cum and shit. She couldn't believe she'd just done that, but something deep within her craved the dirty, taboo feeling of it all.
Feeling dirty and exhilarated, Marina decided to sit in her own filth for a while longer. She was learning to embrace her naughty side, and after all, she was barely legal. Who was going to stop her?
