"We are going to be testing formula 525 variance two today" the doctor said.
Riley rolled up her sleeve and watched as Dr. Verenden emptied the large vial of liquid into her arm.
"Ok riley, you have free reign of this apartment today. We need to keep you here for a bit to make sure there are no adverse side effects. there is food in the fridge and the T.V. you know about have fun!" the doctor said as he walked out the door magnetic lock engaging behind him.
Riley thought to herself "why did he lock the door does he think I'm going to leave without my money?" as she sat down on the comfy couch to watch a DVD.
The doctor walked into the large observation room that spanned two sides of the room to keep watch on Riley's reaction to the formula. sitting at a desk with a laptop and a camera monitor he could keep his eye on riley as he took notes.
11:32 A.M.- injected formula 525 variance 2 felinis familiaris- approximate gestation: 1-2 hours
half an hour through the movie there was a hot sex scene. riley could feel her face beginning to flush and noticed her pussy getting wet. she nonchallantly walked into the other room and grabbed the blanket off the bed and went back to the common room and sat on the couch.
11:58 A.M.- subject seems to be chilly. effects from formula 525?
riley watched as the couple on the T.V. made love. her body began to tingle as she reached under her skirt and rubbed her pussy through her panties under the covers.
12:42 P.M.- first signs of change are apperent; subject's breathing is becoming more rapid. hair is starting to grow where there was none before.
the couch had begun hurting riley's tailbone she spread out on her side one leg lifted so no one could tell she had begun fingering herself.
1:00 P.M.- FUR has increased, much thicker on neck and face her ears have begun to come up in points. she has begun to quietly moan and she seems to be shivering under the blanket we provided. she seems to be suffering some discomfort from the look on her face and the fact that she has repositioned herself. no other feline features are apparent.
riley was starting to notice the sound of purring and was geting hot and itchy. she casually raised a hand to itch her face. the look on her face changed from amorous to shock as her hand felt a soft fur on her cheek. she pulled off the blanket not realizing that she would bare her moist pussy to the cameras, but she didnt care at that point. she was covered in a short milk white fur. she sat up and began tearing off her shirt not taking notice to the pain in her tailbone.
"HOLY SHIT!" riley screeched. the fur covered her once very sexy stomach. she took off her red lace bra, her perfect quarter sized nipples weren't covered.
she had seen enough and wanted to tell the doctor of her horrible side effect. she walked up to the window and said "hello is anybody in there something is happening to me!" she became aware that her panties were getting tight. she took them off and realized she had a long white tail. her pussy looked the same but instead of skin she had white fur surrounding her pink folds.
riley was still horny but wanted to leave now.
1:25 P.M.- changes have not progressed for five minutes. process is complete. formula 525 variance 2 resulted in feline appearance fur and feline tail.
riley was looking at herself in the mirror and noticed how sexy she looked. she noticed herself begin to purr as she thought about going back to playing with herself.
