Story: Werehorse Fingering Herself While She TFs (Patreon)

The moon was out, a cosmic spotlight hanging in the sky and blasting into her room, and she felt it. A tingling sensation began at the base of her spine, crawling up her body, a clear sign the transformation was about to kick in. Her skin felt like it was buzzing, like every cell was suddenly wired to an invisible power grid.

She locked her bedroom door. The horniness hit her like a truck; it was raw, primal, and she decided to embrace it. Her hands, still human enough, moved with purpose, exploring her body as it began to change. Her fingers crawled towards her pussy.

But then, as she started to finger herself, her face started to shift. Her nose and upper lip stretched, morphing into a massive snout. Her nostrils flared with each breath, moving more air as her nasal passages enlarged.

She kept touching herself, the changes to her face only increasing her adrenaline. The room was filled with the sound of her breathing heavy and snorting through those enormous equine nostrils, each inhale and exhale producing a hot blast of air. Her windows were heavily fogged.

Her pussy began to change, the skin around it darkening, taking on a velvety texture more akin to a horse's hide than human skin. The shape altered subtly, her labia majora becoming more pronounced. Her clitoris swelled and grew even more sensitive. The sensation was intense.

Then, her anus started its transformation. It was throbbing and growing into a puffy ring shape. The skin around it darkened, toughened slightly, yet retained a peculiar softness.

Finally, her tail began to grow, a dark, whip-like extension from the base of her spine, adding to the surreal experience. It moved with a mind of its own, enhancing the bizarre transformation of her lower half.

While all this was happening, her fingers were busy exploring the changes. Each touch seemed to encourage the transformation, her pussy and anus responding with a sensitivity and pleasure that was both alien and exhilarating.

As the transformation reached its peak, she felt an overwhelming wave of pleasure building within her. The sensations from her newly horse-like pussy and anus pushed her closer to the edge. Her fingers, now well-acquainted with this strange new terrain, moved with purpose.

And then, it happened. The wave crested, a surge of pleasure unlike anything she'd ever felt before, human or otherwise. She orgasmed, her body convulsing with the intensity of it, the sensation radiating from her transformed areas to every part of her being. Her moan was a mix of human and beast, a deep sound that filled the room. Her tail swished wildly, almost like it was celebrating the climax with her.

She lay there, her breath now coming in long, slow huffs through her large nostrils, pondering the duality of her existence in post-orgasm clarity. Here she was, part human, part horse, living a life that was both ordinary and extraordinary. A smile, or what passed for one on her horse-like face, spread across her features.
