The woods were dark and dense, the perfect place for a Pokemon like Ninetales to wander undisturbed. With his fiery tails and cunning mind, he was used to being in control. But today, he found himself faced with a proposition that would change everything.
As he stalked through the underbrush, Ninetales caught a glimpse of movement out of the corner of his eye. He turned to see a massive Arcanine, quadrupedal and powerful, with a striking 12-inch knotted cock. Ninetales' eyes widened in surprise, but he held his ground.
"Hello there," the Arcanine rumbled, his voice deep and commanding. "I've been watching you. I propose a deal: mind-blowing sex, but you would become my property."
Ninetales hesitated, intrigued but wary. He had never been one to submit to anyone, but the Arcanine's proposition was tempting.
"What would that entail?" Ninetales asked, his voice sharp and curious.
The Arcanine gestured towards his sheath with a paw. "Come closer and find out."
Ninetales approached cautiously, his heart racing with anticipation. He stuck his tongue into the Arcanine's sheath, tasting the precum and arousing the larger Pokemon. As he explored the depths of the sheath, his own cock began to awaken.
Suddenly, the Arcanine took one of his paws and forcefully inserted it into Ninetales' urethral opening. Ninetales cried out in surprise as the Arcanine scorched him with his fire-type powers, burning away the erectile tissue but leaving everything else intact.
Ninetales' cock remained hard, and the Arcanine used his precum as a lubricant, diligently stroking Ninetales' glans. After 5 minutes of rubbing, Ninetales released a torrent of pinkish precum.
The Arcanine admired Ninetales' modified cock, lifting it up and tasting it. Ninetales started to ejaculate, and the Arcanine savored the taste.
Ninetales' cock shifted, the knot receding, and the sheath closed up, leaving the modified cock permanently exposed. Ninetales' testicles transformed into ovaries, and he slowly became more feminine as he ejaculated.
The Arcanine lay on top of Ninetales, and stuck his cock inside Ninetales' new modified cock, causing incredible pleasure for Ninetales. The Arcanine humped Ninetales' cock, and filled it with virile semen.
Ninetales' new cock throbbed, and the semen remained inside until their next orgasm. Ninetales' new cock, filled with the seed of their lover, throbbed and elicited moans from Ninetales.
The Arcanine pulled out, and Ninetales' new cock remained semi-erect, holding the semen inside. Ninetales, now more feminine, expressed their willingness to fill the void inside their new cock.
The Arcanine, satisfied with his handiwork, complimented Ninetales on their new appearance. "You look beautiful, my dear. I'm glad we could come to an agreement."
Ninetales smiled, feeling a sense of satisfaction and belonging that he had never known before. He was no longer just a Pokemon; he was a creature of pleasure, bound to the Arcanine and ready to explore the depths of their desire.
"Yes," Ninetales said, their voice softer and more feminine than before. "I'm ready to be your beast."
