"Look, I'm just here for the sex, so let's get this over with." Nick sighed, and breezed past her towards the stairs. He began climbing the thick carpeted steps, getting higher and higher as he neared the fourth floor. "Yes..." Annika whispered to herself as she started up the stairs, "Let's get this over with..."
At the top of the stairs, Annika lead Nick down a dark hallway. He could hear strange sounds coming from behind the doors in the hallway, and shivered. After turning down two more hallways, they arrived in front of a huge white door with large "A" stamped on it in gold lettering. "Are you ready, big boy?" Annika whispered in Nick's ear, and he moaned. His pants were getting tight. She grabbed the handle and swung the door open wide.
Annika's room was large, with thick cream-colored carpet and many shelves lining the walls. She had cleaned up the magic supplies that usually adorned her shelves and floor that afternoon as not to draw suspicion. A huge window next to the four-poster bed with a purple comforter overlooked the misty grounds of the mansion. Nick stepped in, surveying the room. Closing the door behind him, Annika put her hands on his shoulders and whispered into his ear, "Get them off. Now." Nodding eagerly, Nick undid his belt and threw it into a corner. He took off his pants, jacket, and shirt, until he was just wearing his black boxers. Meanwhile, Annika had stripped completely.
"Black... how appropriate..." Annika whispered, then got down to her knees and pulled down Nick's boxers, allowing his huge, stiff cock to flop out. "C'mon, to the bed..." she said, getting to her feet. He started towards the bed, but she stopped and kissed him once on the check. It stung for a moment, and for some reason, he suddenly smelt a primal, savage scent. Shaking his head, Nick advanced to the bed, where Annika was on her hands and knees.
"Doggy style... never thought of you as that kind of girl..." Nick said. The sight of Annika's cunt sticking up in the air, waiting for him, caused him to moan and jizz on the carpet. He didn't notice that it was thicker and darker in color than usual. He climbed up on the bed and positioned himself behind Annika. He was so lost in a lustful haze he forgot to put on a condom. "Ready, you rude boy?" Annika asked from below him. "Ready..." Nick moaned, then shoved his dick into her.
Instantly, they both started moaning in pleasure. He humped harder and harder each passing minute. Juices from him and Annika ran down their legs and puddles on the bed. After a few minutes, Nick started to go into overdrive. He opened his mouth and moaned so loudly that his face stretched out into a short muzzle. His teeth grew outward into huge fangs. Sleek, jet-black fur started growing on the sides of his muzzle as whiskers pushed out of his cheeks. His nose got dark and wet as his whole head got engulfed in the fur, which was rapidly spreading down his neck.
His ears grew rounded and moved to the top of his head as his forehead was pushed back and slanted while his muzzle pushed out even farther. His eyes glazed over and turned yellow. His thickened, rough lounge lolled out of his mouth, and he snarled in pleasure as his neck thickened with muzzle and pushed his head out farther. As the fur traveled down his stomach, back, and arms, his shoulder blades were pulled closer together, causing his arms to be splayed out in front of him. His arms bulged with muscle under the black fur as his hands popped into huge, three-toed paws with wicked sharp claws at the end.
His back cracked and forced his spine to straighten out, causing his legs, which were now swamped with sleek black fur, to splay out over the side of the bed. The fur covered his entire body now. His back broadened as his stomach and chest pushed out hugely. His thighs and butt bulged with muscle, increasing in size exponentially. His Dick got attached to his stomach in a sheath, causing him to slip and fall onto Annika's back. His feet lengthened as his huge thighs shortened, feet popping into huge three-toed paws with claws on the end as well. His hips widened as they merged with his huge butt, becoming haunches. A sharp prick came at the base of his tailbone, and a huge, thick black tail squirmed it's way out of his gigantic hindquarters, snaking and bending as it reached over three feet in length. Opening his muzzle, Nick let out his first truly animal sound: a loud, pleasure-filled roar.
At this point, Annika was being humped by a gigantic black panther. Reaching her hands back, she shoved it out of her and Nick let out a yowl of terror as he tumbled off the bed, landing in a heap on the floor, unsure of his new quadrupedal position. Looking himself over in shock, he finally became aware of the changes and yowled in terror. Nick turned to run towards the bedroom door, but tripped over his huge front and back paws and his tail. He rolled and landed against the wall in a heap. By this time, Annika had already put on a sweater and some jeans.
She walked over with a glowing silver collar in her hand. Yowling, Nick squirmed to get out of her way. "Quit resisting or I'll turn you into a panther cub." She snapped as she clipped the collar around his huge, muscular neck. Instantly, Nick got to his paws and looked at his mistress for orders, but unwillingly. Internally, he was screaming. She bended down and looked him straight in his feline eyes. "This is your punishment for being a sexist pig." She said simply. "And for that, you get to guard my room for who knows how long. If I'm generous, a week at most, If I'm not, well, you'll never see your family again." She snapped. "Now, go get me some paper towels. You made a mess, you horndog ."
She opened the door and Nick bounded out, padding down the hallway towards the bathroom all as he tried his best to resist, but Annika's magic prevented it.
