A first submission so please don't treat me too harshly. Short but heated :)

It was during a nasty thunderstorm that he arrived at the cabin. He was tired from the long drive, yet the moment he opened the front door his ears perked up. There was a smell that he recognized, from walks in the forest. He remembered her running, just visible in the corners of his eyes; calico fur darting between the trees. He had had a hard time forgetting her last time. It was several months ago now, he really needed to get out here more often. He had to forget about her, wolves normally would not mate with felines.
Her scent was here though, in his cabin. How had she gotten inside. He put his suitcase down gently and got on all fours, sneaking quietly, following his nose. His sensitive wolf's nose could scent right away that she was not yet aware of him. He also knew she was in the bathroom, around the corner of the hall. As he heard flushing he darted into the living room, hiding from sight. He had forgotten about his suitcase.
He saw her leave the bathroom and pad softly on two feet through the hall before stopping and turning to the door. He could smell her fear rising and another scent, one he didn't immediately recognize. As she faced the door he quickly charged up from behind, and took a hold of her. He shoved her further, until she was pinned against the door.
"What are you doing in my cabin little cat?" He could feel her trembling against his muscular body, small against his larger wolf stature. She didn't reply fast enough for his tastes; he growled next to her ear. There was a small whimper in return and the mysterious scent increased. He inhaled slow and deep, trying to catch more of it to identify what it was. The realization surprised him; the bitch was getting excited.
Here he had been, trying to forget the feline for weeks before. Now she was in his cabin and, judging by the smell, wanted nothing more than to be filled with a load of wolf cum. He had to make sure, one of his hands released her wrist while a growl urged her not to move. He moved his free hand to her cunt. It was wet. Not yet dripping but, it could very soon be. He snickered, the smaller form of the cat shivering against his body.
