"Ashley," said Joshua slowly. "I knew you didn't need any help in biology. I tutored you for the same reason you asked me to... I just wanted to spend time with you. There's always been something very beautiful about you. I'm... not very good at speaking my mind. I was afraid that you would reject me if I said anything."
Ashley was nearly crying with joy... his words touched her so deeply that she almost forgot about her heat. "We don't have to be afraid anymore," she said, reaching out to hold him gently to her naked body in an embrace. "We don't need anything anymore, anything at all, except each other."
"So... um... what do I have to do?" he asked, obviously summoning up his courage.
"Are you ready now to say goodbye to your human life?" asked Ashley. "Once we begin... you can never go back." Joshua nodded, not without some thought. That pleased Ashley... she knew he would make an excellent werewolf, and that he would have no regrets. "Take off your clothes," she said.
Joshua turned beet-red. He reached for his shirt and slowly pulled it off, revealing his unremarkable upper body. "I know I shouldn't care, but..."
"You'll need to say goodbye to everything you knew as a human," explained Ashley compassionately. "And I want you to do it willingly. I also want to see my mate's body... his whole body."
Joshua removed his pants and socks without incident. Ashley looked down at his underwear, where a protrusion marked his clear arousal. She smiled in approval, and gently urged him on: "All of your clothes."
Deeply embarrassed, Joshua finally shed his last piece of clothing and stood erect and naked before the equally unclad female. "Are you... going to bite me?" he asked. "Will it hurt?"
"I could," answered Ashley. "But I know a better way to turn you." Stepping forward, she kissed him deeply on the mouth. One of her hands reached down to caress his member, and another reached around to gently rake her fingernails down her back. Her heat was overpowering, and Ashley shivered in the kiss, knowing that, at last, her heat would be satisfied. The kiss was enough to make him like her, and she would give him more than a kiss.
Ashley pulled Joshua to the floor and began to lick his erect shaft lovingly. Joshua groaned in more than just passion... she could feel his body heat rising as he began the first stages of the change. His muscles rippled and became more defined, his shoulders becoming strong, the muscles in his arms and legs flexing as they gained mass. His physical blemishes were disappearing, his body becoming that of a lord of beasts. Ashley continued to lick his penis and caress his body as he changed. Eventually, Ashley registered a new scent... the scent of a male werewolf, virile and ready for mating. Her lust went into overdrive and she found it impossible to remain in human form... her teeth lengthened into fangs, her ears became pointed, and her fingernails began to lengthen. Shuddering in ecstasy, she turned away from him and got down on all fours as six more breasts emerged from her torso, quivering as they swelled. "Enter me," she said in her deepening voice. "Fill me. Become."
At last, she felt his weight on her back. She felt his fingernails now lengthening into claws, grasp her offered waist, and at long, long, last, the white werewolf bitch felt a thick penis enter her burning vagina. She had needed this since her forced transformation earlier today, and now, at last, she had it: a male mounting her, thrusting into her with bestial vigor again, and again, and again. She felt the massive, thrusting form atop her grow silky fur even as her own fur grew in, tickling every inch of her body, and heard Joshua's moans of passion turn to growls even as her own neck elongated slightly and her vocal chords changed. Looking at their reflection in the living room window, she saw Joshua, exactly halfway between human and werewolf, thrusting powerfully into her. With a crack, his legs shifted to digitigrade, allowing him to rest atop her much more comfortably, and his clawed hands, shaking with the heat of his first transformation, reached around to grab her still-swelling rows of breasts. Finally, she watched his face push out slowly into a lupine muzzle, causing him to whine in pain and pleasure as his large, furry balls tightened and he released his seed into his mate. Ashley shut her eyes against her own reforming skull and screamed as she clamped down hard on him, her body desperately grasping for every ounce of his precious semen.
After the blinding orgasm which overpowered her senses finally receded, she was aware of him gently licking her ears with his new long, soft tongue. Her tail wagged as she realized that his transformation was now complete. Joshua was no longer human... never again would he wear clothing, being perfect now in body, mind and spirit. He was free from all fear, and ready now to join her as the Male Alpha of the Wolves of the Light, his fur as snow-white as her own, his eyes a beautiful silver. He lifted her up, still impaled on his member, and she turned to face him, loving the sight of him. The two licked and nuzzled each other lovingly for a long time, and mated twice more, once against the wall and once with her lying on her back and licking his muzzle as he filled her, before they left out the back door and into the fields and hilly woods of the hinterlands of the town.
