The more she stared at it, the more her willpower faded, as if just the sight of that thick cock was enough to start her change. Her fear turned to curiosity as her body started to produce a musk starting at the masculine member. She took one finger at dragged it down the length of her shaft and felt it pulse and throb, dripping precum down on the floor. Gina couldn’t stop herself, she had to stroke it, her mind was completely broken. Taking her entire hand, she pumped her cock quickly as the rest of the effects of the virus started to effect her. With her mind focused on rubbing her meat, Gina could do nothing as her hips widened a bit and a flesh colored tail started forming just above her ass. Her sweaty body started to get even warmer as thin, brown hairs on her body got thicker and longer, but she just kept stroking. Her face and teeth started reshaping first, giving her a more rat-like face. Her feet stretched out to be pretty large, going from her usual size 7 in women’s to a size 14 in men’s. Her fur kept growing as she kept pumping, turning her more and more into a rat with each inch in length. Her ears traveled up her skull and stretched out pretty far, giving her a more rat than human appearance. Her tail grew to be 3 ft in length before she felt her climax closing in. She let out a loud and wet belch as her tits and stomach inflated slightly, giving her a small gut with DDs. She opened her eyes wide as she couldn’t control her orgasm, spraying the bathroom wall with her sweaty, musky, rat jizz. Even her cunt dribbled femme cum down her furry legs and into her panties and jeans.
After calming down enough to think rationally, Gina looked at herself in the mirror. What she saw should’ve freaked her out, but with the virus affecting her mind as much as it was affecting her body, she got turned in by it. She actually lost a few inches in height, her thick pelt of brown rat fur made her look voluptuous, the pattern drawing her eyes to her luscious hips, bubble butt, and hefty rack. She traced her body with her fingers as her nipples stood erect. She watched as her now flaccid (still human-shaped) cock drooped down to her knee as her furry balls hung about halfway down her thigh. She stood and posed, the virus telling her she loved the new look, and wanted to spread it further. Pulling her wet panties back up with some difficulty, her spine tingled at the feeling of her juices rubbing against her moist pussy, coating her balls in her musky juices, and making her large dick hard. She slid her jeans up to her thighs and struggled to pull them up. She heard a loud tear as she finally got the denim past her voluptuous thighs, both the thigh and seat seams opened up wide, her panties and brown fur spilling out of the new holes.
“Man, I liked these jeans.” She said, unbothered by her new lewd appearance.
She walked out of the bathroom to see her daughter, Susie, who had aged up and turned into a white rat anthro, vigorously masturbating while covering herself in jizz. Just the sight of it made her thigh tears wider as she started to get hard again.
