As I stepped into the bathroom, my heart raced with excitement. I had never done anything like this before, but the idea of exploring my scat fetish was too enticing to resist. My gorgeous girlfriend, Galaxxx, had suggested we try it together and document everything on camera. I closed the door behind me, locking myself in. The tile floor was cold against my bare feet, but it only added to the thrill. I positioned myself over the toilet bowl, my heart beating wildly in my chest. My pussy was already wet with anticipation. Slowly, I eased myself down and spread my legs wide apart. The cool air on my cunt made me shiver slightly, but it only served to heighten my desire. With my ass raised high and my pussy exposed, I felt incredibly vulnerable yet turned on at the same time. I lowered myself further onto the toilet seat until I could feel the cool metal against my ass cheeks. Then, without hesitation, I began to push. At first, nothing happened - just a few small, unsatisfying gasps. But then, gradually, the pressure built up inside me. I closed my eyes and let out a long, tortured moan as the first wave of shit forced its way out of my pussy. It felt so good - so debauched - to be filling the toilet bowl with my own excrement. My pussy clenched around my finger, milking every last drop of pleasure from the act. The sensation was overwhelmingly intense as the shit continued to flow. It gushed out of me in huge, glistening globs, coating the insides of the toilet bowl and dripping down onto the floor. I couldn't help but grind my hips back and forth, fucking myself with each passing wave of wet shit. As the pressure eased up, I reached between my legs and began rubbing my clit furiously. I caught glimpses of myself in the mirror, sight of my ass cheeks gaping wide open and my face contorted in ecstasy. It was a powerful aphrodisiac - seeing myself like this, so totally submissive and depraved. I came hard as another torrent of shit erupted from me, coating my thighs and dripping onto the floor. My cries of pleasure echoed through the room, mingling with the sounds of my own body betraying me. Finally, spent and exhausted, I managed to empty my bowels. I sat back on the toilet seat, my legs shaking with the effort of holding up my weight. A mountain of steaming shit piled up around me, a testament to the incredible intensity of the experience. With trembling fingers, I reached between my legs and wiped away any remaining traces of feces from my pussy. Then, gathering up my courage, I looked down at the mess I'd made. A trail of fresh shit led from the toilet bowl to the door, where Galaxxx was waiting with a camera in her hands. "Well," she said, smiling proudly, "that's one way to start our scat journey together." I couldn't reply - all I could do was nod in agreement as the realization dawned on me: this was just the beginning.
