This was so much easier in the old days, as they had wine and wild parties, however nowadays they had to be a bit more... thorough. Today, a nymphs would do the legwork, seducing him with their incredible bodies, while the satyrs would provide protection and beat any interlopers to death.
The nymphs wasted no time in attacking Julian, their lips and tongues travelling up and down his body. He felt like he was being devoured, but the lips and tongue were those of a goddess.
He let out a wail that was a mixture of horror and pleasure. A pair of them licked and kissed him for a few minutes more, before one nymph claimed him. She crawled on top on him and began to work her magic.
The nymph began to rub herself against him, wrapping her long fingers around his arm and guiding it to her lips. She kissed the underside of his arm, before moving up to his shoulder and kissing there. She kissed her way up his neck, leaving a trail of pleasure-filled kisses along his jawline and up to his lips.
There was a dull pain as Julian began to feel his jawline strengthen, becoming sturdier and slightly more square.
His teeth were starting to sharp, his canines growing longer and pushing forward. The nymph straddled him, grinding herself against him and kissing him. He could feel more changes rippling across his flesh.
His body hair was beginning to sprout, his legs becoming hairier and hair growing from his arms. His chest, however, remained bare and pure. It, when fully developed, could titillate Innocence, and insnare would-be invaders of the woods. However the hair was greenish brown, like a plant. It was knotted with small specks of pollen.
Around his member, his pubic hair thickened until it grew thick and wild. It was filed with tiny flowers, which were white and beautiful. His hair thickened and curled, also taking on the green colourisation. It grew various small leaves and small flowers, all the while the final change erupted though Julian.
He could feel it, his humanity, slipping and pumping away.
His hips thrust up, and he could feel a tearing pain, like his member was being torn apart. It grew two inches longer, gaining a greenish hue. His member itself was thick and veined, and ready for action.
His testicles, two beautiful orbs of green, forever a bit larger as this plant green spread further.
His chest and limbs grew into a ethereal green, began to thicken with lean, and yet strong and defined, muscle.
His skin kept its youthful touch, but yet became rugged and sturdy. His veins grew wider and became a darker green, like a leaf. His strong, athletic form boomed with strength and purpose. The muscles became defined, their contours better placed and more solid.
"You look magnificent," The nymph spoke, staring at Julian in pride.
"Thank you." He said, feeling the magic shifting and forcing the final marks of his humanity fade.
He blew his load, flushing away what was left of his humanity.
He relaxed, spread across the grass, spent.
"Well then, you're a new man." The Nymph smiled, and stepped back. The other nymphs applauded themselves, overjoyed about a new member to join their ranks.
The satyrs shrugged, and decided to move on. They had a celebration, a new member to join their little group of fauns and nature spirits.
