Carrie grabbed John's hand, dragging him away from the street.
"What the hell?" he asked, glancing back at the still changing trio.
"Don't..worry about them..." Carrie said as she dragged him into an alley. She wanted him, she wanted the change...but not in front of everyone else.
The alley was deserted, lit only by the moonlight that poured down upon the two of them. She grabbed John, kissing him fiercely as she struggled with her top. She pulled away, grinning with a combination of lust and mischief.
"What the hell's gotten into you?" John asked. "The show's back that way."
"You want a show, love?" Carrie asked, holding the shirt closed with her hands. All she had to do was let it fall open, and the magic would start. "I'll give you a show that's ten times better than the one we just watched."
She tilted her head up at the moon, staring at it for a moment before pulling her shirt wide open, discarding it with a gasp. Immediately, her nipples stood rock hard as she trembled in the first embrace of the moon, her body beginning to succumb to the magic of the costume.
She grew increasingly and immediately wet, hiking her skirt up, flashing her shaven pussy in the moonlight. "OHHHHRRRRRRR..." she moaned, beginning to growl as her hand quickly went to play with her clit.
"Ho...Holy shit..." John muttered, staring at his new bride getting herself off as fine brown hairs began to blossom around her mound. Her pussy was twitching and jumping in the light, shifting with undeniably pleasurable effects.
"John...John..." Carrie growled, grabbing his hand, leading it to her vagina. "Feel my heatrrrrrr.." She pulled him to her, and John felt her boiling pussy twitching under his fingers, spilling cum and musk down his hand. He began to massage her himself, at first reflexively, more out of habit, and then with purpose, as he realized it made her change more.
Carrie rocked against him as her tits shrank back for a moment, with complementary sets growing on her torso. Her ears streched upward, growing pointed, and she licked at his neck, wondering what might happen if she bit him. She continued to growl and moan, and their lips met in a sloppy and passionate kiss as her nose grew blackened and leathery.
John was ragingly hard and ragingly horny, though he was still unable to explain why this was so hot. Their eyes met, and John was struck by how attractive he found her like this, covered in fur, her face starting to stretch into a muzzle. Spinning her around, he bent her over, knowing she wanted it, and wondering how much more attractive he'd find her in her full werewolf form.
Slamming his cock in her willing and accepting vagina, he began to say, "Change, change for me!" He pulled her hair, fucking her roughly, sending Carrie's transformation into a final overdrive. With every thrust, her bones snapped, her muscles swelled, her muzzle grew out a little further. Carrie went from gutteral growling moans to howling ecstasy quickly, and as John erupted into her, he no longer was fucking his wife, but a full fledged, sexual werewolf woman.
As they separated, she let out a howl, rising back up to two legs.
