Thunder - One Size

Felix was a young man with a heart full of adventure and a spirit as wild as the landscape that surrounded his home. His best friend, a mighty Anthro-Horse named Thunder, so large that his mere presence would leave even the strongest trees in awe. What set Thunder apart from others, however, was his unique ability to satisfy the deepest, most primal desires of his companion.

On a warm summer afternoon, as the sun painted the sky with fiery passion, Felix was drawn to the stables where Thunder was lazily lying of a bag of fresh hay. Felix curiosity had been aroused when he was once again cleaning the big stable and caught a whiff of a distinctly masculine scent lingering in the air.

As he approached Thunder, he noticed that there was indeed something strange about his equine friend. Between his powerful hind legs, where a horse's tail usually sits, was the soft, velvety protrusion of his penis. The sight made Felix's own member throb with curiosity. He cautiously stretched out his hand, which trembled as it touched the warm, flexible Shaft.

“Go on,” Thunder murmured softly.
Encouraged, Felix became bolder and stroked and caressed the velvety shaft with a gentle touch. As he did so, he could feel his own arousal increasing and his mind was racing with thoughts of what might be. Thunder grew larger and firmer under his touch, reaching a size that surpassed even the most exaggerated stories he had heard in the village tavern.

Without another thought, Felix opened his pants and released his own erection, feeling it throb against his stomach with arousal. Felix looked him in the eye to ask for his consent and received an unmistakable look of understanding
and approval. His warm, fragrant semen was already dripping from Thunder's penis. With a deep breath, Felix pushed his penis into the warm, inviting opening of the horse's cock.

The sensation was unlike anything he had ever felt before. The velvety softness of the Thunders penis enveloped him like a warm embrace, and the feeling of the pulse echoed through his own body. He began to penetrate, slowly at first, savoring every inch of the touch, feeling the horse's cock stretch and conform to his human form.

As their rhythm intensified, the barn echoed with the sounds of their passionate mating. Felix's mind swam with pleasure as he felt himself
approaching climax. He gripped the Thunder's powerful flanks, his fingers digging into his muscles as he quickened his pace. And then, in a moment of pure ecstasy, he climaxed, his semen spurting deep into Thunder's cock.

The world around them fell silent, the only sound the panting of their labored breaths. From that day on, their friendship deepened even more, and their secret was only shared between them.
