Susan sat on her ass stunned as she looked up her changing boyfriend, it wasn’t supposed to be possible but before her very eyes her boyfriend was changing before her eyes. His t-shirt began to rip as he grew at least a head taller than he had been before. His jeans which where around his ankles because she had been giving him a blow job had been reshaped to take on a more animal like trait and was covered with grey/white fur with black spots on it. A long bushy tail was moving back and forth behind him as more fur began to appear on the front of his legs and on his arms.
“My God.” Said Susan as she stood up and prepared to scream but before she could do anything, Tim was upon her. She felt a gentle wetness on her belly button, she had been wearing a top which had shown off her midriff a bit and now her boyfriend was kissing it as his hands held the back of her legs. She knew what was coming next but it still felt so wrong yet strangely so right as her boyfriend pulled down her pants and underwear to show her womanhood.
She couldn’t see it but already snow-white fur was beginning to grow around her womanhood as her boyfriend’s now cat like tongue licked her.
Her scream for help died right then and there, replaced by a moaning purr as he began to pleasure her like she had done to him.
Her hands reached down and grabbed the sides of Tim’s head to attempt to pull him away only to pull him closer as his face became fully covered in snow leopard fur as his ears changed into more cat like ears sticking out of the sides of his now pure silver hair. His shirt ripped down the middle of his back and fell away as the snow leopard fur covered his whole back even as his tail grew ever longer
Her changes took on a more rapid rate than Tim’s had thanks to the larger amount of the virus she had gotten. Her face began to shift a bit, her nose taking on a more cat-like feature while her teeth became fangs. Snow white fur began to grow around her mouth and down the front of her neck. Her hands now graced with cat claws moved away from her boyfriend’s head and ripped off her top at the same time her bra snapped, freeing her now larger breasts which grew at least a cup size if not more. White fur ran down her neck over her now larger breasts before thinning to a point ending her womanhood. Her black hair remained the same, however orange fur began to grow on the rest of her changing body, darker tan spots with black around them began to grow as well. Once her top was off she reached back and snapped the band holding her long black hair back in a pony tail letting that fall around her draping her shoulders, she often did that during sex and this was among if not the most pleasurable thing she ever had experienced.
If she hadn’t been so lost in pleasure, she would have known the pattern of the fur which now graced her body.
A Jaguar.
She felt her climax come as she let out a quiet roar, she still had enough human mind within her to know she had to be quiet. She could now smell and hear things around her that she couldn't before, she may be lost in pleasure but danger was near.
When her eyes reopened, she wasn’t afraid anymore instead she stood there a fully transformed jaguar women looking into the eyes of a fully transformed Snow Leopard man, her mate, the remains of their human clothing on the floor.
