A restless night.

Sarah woke up to a loud thump from the direction of the guest room. "John, what are you up to?" she thought to herself. He's probably still trying to get that repulsive thing off his penis. She had a sudden surge of sympathy; John would do anything for her, and she was treating him like some kind of pariah in his hour of need. Even getting rid of that ring was something he was doing for her.

She walked quietly to the guest room and cracked the door to peek in. John was lying en flagrante on the bed, tossing and turning with his partially-erect cock flopping from side to side; he appeared to be in pain, but the moonlight shining through the window clearly revealed the dark band at the base of his shaft. What a complete turn-off.

Sarah sat on the edge of the bed beside him; after all this was her man, and he was going through something. He cried out in pain and there was a strange ripping sound. She checked him up and down to see what was wrong and saw the cock ring split and fall off him. But that wasn't all.

John's skin rippled and writhed as he flailed about, but what held her attention was his dick. It was thrusting and growing, not just to his normal erect six-and-a-bit inches but bigger; like, double the size. And it was sprouting hair, just like the rest of his body. His fingernails and toenails grew into claws and muscles piled on muscles. His legs partially bent so they looked more like animal legs and his face was stretching and distending into a wolf snout.

She scrambled away from the bed. This wasn't John, it was some kind of monster! A werewolf? The wolf-man that used to be her husband sprang into a crouch and watched her with an intense focus.

"Don't eat me, John!" she screamed.

He leaped, claws out and forward. Sarah whimpered, but instead of tearing her flesh the wolf-man ripped away her nightgown. A huge long tongue lapped out and circled one breast, spiraling inward until it reached her nipple. Then it repeated the movement on her other breast. His warm wet nose smelled and snuffled the space between her breasts as she lay on her back helpless under his weight.

"John?"

Wolf-John licked her from her navel to her neck, making long soft strokes and thrilling her with every touch. Fear began to give way to passion at the firm but gentle touch of the beast.
