"Werewolves."
Ty felt her anticipation surge. Werewolves had been one of the few ways he'd allowed himself to experiment with his sexuality before he changed. Their handsome furry animal-like bodies pounding into a girl just turned him on way more than he knew it would.
"Is that OK with you?" he asked. "We don't have to if-"
"N-no, it sounds hot!" she assured him. "Is it OK if I change you first?"
"Please do," the handsome man smirked. Ty focused and willed her lover's body to transform. Before she knew it, his hairy muscular skin had begun to ripple and sprout a thick pelt. His pants of pleasure turned to guttural growls. His scent seemed to turn deeply unfamiliar, yet just as intoxicating to the young woman he lay atop.
His skeletal structure began to alter, and she heard his muscles and bones convulse as they became more animal and stronger. His hands and feet formed paws with sharp claws, and his face began contorting into a snout and grew thick lupine hair all over. She saw his teeth sharpen into an intimidating shape, though she knew she could trust him not to use them on her.
He whined as something at the base of his spine gave, and Ty saw him wagging the tail that emerged from his back. She felt his wet nose sniff loudly at her as he drank in her feminine scent, asserting to him this was his brood mare.
Fittingly, the last part of Eileen's human body left- his thick dark penis- altered into its lupine counterpart. He groaned as it thickened and lengthened, the tip honing to more of a point while the base expanded to form a knot. Ty stared intently at her lover's phallus and balls, sensing them tingle as his lycanthropy altered the millions of sperm within him.
The werewolf lapped at Ty and she whimpered as she felt it rub its newformed tip against her clitoris. Fuck, this wolf would breed her...
