Trevor Best was a werewolf. He was born a werewolf but lived his childhood like a normal human. Then, on the day of his 18th birthday, his father set him down and told him about their family secret. Trevor didn't believe him, at first. However, that night when the full moon was high in the sky, his first transformation occurred, entirely against his will. Luckily, his father was there to guide him. In the form of two wolves, they ran across the nearby forest on silent feet, tongues lolling, yellow eyes shining. They made their first kill - a small deer - and shared it. Afterward, they hid in a cave his father had found, where a spare set of clothes was waiting, tucked behind a rock. When morning came, they dressed and walked home as men. Trevor felt their bond couldn't be stronger, after that.
That is, until he brought his first girlfriend home.
Trevor's father took one look at the prim and proper blonde, and pulled him aside.
"She's not the one for you, son," he told him. Trevor did not listen to him. He was young, he was horny, he wanted to fuck her. So, he did. Everything was going swell, until the first full moon. Then, he discovered that she was scared of him. Worse, when he tried showing her his secret, she freaked out so bad, she threatened to oust him.
She was almost out of the woods, before his father caught up with her and ripped her throat out.
Things were not the same, between his father and him, after that night. Still, his father was always there for him when he was needed, and Trevor had no real reason to hate him. If anything, he was grateful to have someone with experience helping him. One day, after dinner, he waited for his mother to leave, before quietly asking his father, "Does Mom know?" To which his father said, "Yes, but we never mention it. Wanna know why?"
"Why?" Trevor asked, dumbfounded.
"Because, my son," Trevor's father said, slowly, "she thinks I can't remember anything I do, when I'm a werewolf."
"But that's not true," said Trevor. "You should just tell her."
Trevor's father looked at him long and hard.
"Son, when you've mated for the first time as a werewolf, I'll ask you if you still feel that way. Till then, please reserve your judgment and don't say anything to your Mom."
Again, Trevor was dumbfounded, but he realised there was something about the werewolf mating that he did not know, and that his father wasn't comfortable telling him. From that day on, he decided never to be with a girl on the night of a full moon. His life continued as normal, with many girls coming into his life and leaving it, none the wiser. None of them could keep his attention for more than a few weeks. This was fine by him and fine by his father. Only his mother sometimes complained.
"I wish you'd find a nice, steady girlfriend, Trevor," she would say, sighing. Trevor didn't have the heart to tell her the truth, which was that he planned to remain single until his dying days, and so break the cycle of the cursed werewolf gene, once and for all.
***
Three years after his first night as a werewolf, Trevor met the love of his life.
Her name was Laura Edwards, and she was the daughter of a priest. One could hardly imagine a more inappropriate match for Trevor, who by now had a real reputation as the ladies' man. Nonetheless, from the moment he first laid eyes on her and inhaled her scent, Trevor was hooked. He stalked her without her knowing it, day and night. The only time he stayed away was during the night of the full moon. But even then, he thought about her, in his wolf form, and when he did, his wolf cock would emerge, all big and hard and with a giant knot at its base. The first time Trevor saw his wolf cock, he was horrified. Then he got used to it, maybe even a little proud.
The truth was, his wolf cock was twice the size of his human cock. Of course, he never planned to use it on a girl. Especially a girl that he truly liked.
Trevor remained steadfast in his resolve for many months. When he began dating Laura, he came up with a good excuse as to why he would need to be absent from her one night each month. It was his night to go out with the boys, he told her. She believed him, for a long time, and without question. Then one day, over dinner at his house, Trevor's Mom happened to mention how much of a loner Trevor was. Naturally, Laura smiled and said, "Except for the night he goes out with his male friends."
With that, his ruse was blown. His mother knew nothing of any male friends and said so. Laura looked at him with narrowed eyes, before reverting back to her charming self. Later, of course, she questioned him at length. His answers failed to satisfy her. When the next full moon came, he saw her following him as he left the house. She thought he did not see her, but he could smell her from a mile away. Werewolves had extra sensitive sense of smell, even in their human form. So, he watched her out of the corner of one eye, and he ran through the forest to get away from her.
The foolish girl followed him and promptly got herself lost.
