It was lucky for Jen and Sam that the police hadn't thought of searching in the woods a mile away from Frank and Gillian's house. As far as they were concerned they were searching for a large dog. Both Frank and Gillian were in deep shock and of little help to the authorities.
Back in the woods, Jen woke up feeling fantastic. She also felt a cool breeze, since she was stark naked. Feeling unusually frisky and strong, she flexed her muscles and turned to see the furry shoulder of a werewolf obscuring her view of the sunrise. The huge mound of muscle and hair shook and began shrinking until its texture was that of pink flesh with only a few stray hairs dotting the area around the thin neck. The beast's claws also shrank and curled until they were thin fingers with short, trimmed nails. His tail began twitching as it was sucked into his softening rear end, till there were only two plump, pale cheeks and a cluster of hairs above. And the huge sheath separated from the belly and flopped downward into a flaccid tan tube whose mushroom head brushed the grass. She saw her brother's sleeping, peaceful, near-angelic face turn toward her as the reversion concluded.
Hours earlier, the enormous she-beast had used her front paws to pin the male down while maneouvering her sex onto his limp penis. Sam -wolf was too tired to respond. She sighed, turned around, and began sucking him off. It took an eternity until his organ finally emerged from the sheath. After that he engaged in a mechanical round of penetration with the she-beast, who demanded that he stay at it for what seemed like forever. After climax, and a few perfunctory love bites, he waited for his knot to deflate and then went off to sleep. The she-wolf, sad that her mate seemed bored of her, cried herself to sleep, facing the inert male's backside. She changed back soon afterwards.
Now Jen lay staring up at the trees, the chriping birds and the beautiful green hills. The sun was now up and strong and the morning breeze had lessened. She wondered what she would so now. She idly ran one of her feet along Sam's chest. He still didn't wake up, and she resolved to wake him until she heard a twig snap, and immediately got on her knees in alarm. She heard another twig give way, and waited for the cause of the disturbance to show itself...
