Daniel stepped into the transformation chamber, his bare skin prickling with anticipation. The door sealed shut behind him with a soft hiss, and Dr. Laura's voice crackled over the intercom one last time.
"Beginning transformation sequence. Just relax, Daniel—let the instincts take over."
A warm mist filled the chamber, swirling around his body. At first, it just felt like a pleasant tingle—but then, the heat deepened, sinking into his bones. His muscles tensed, then melted, his frame shifting, reshaping. His waist nipped inward as his hips flared dramatically, the curve of his body becoming unmistakably feminine.
"Nngh—ah!" His voice hitched, already higher, softer.
His hands flew to his chest as his pecs swelled, flesh bubbling outward into heavy, round breasts—plush and sensitive, his nipples stiffening into pink peaks. A shiver ran down his spine as his skin grew smoother, softer, a fine layer of downy fur spreading across his arms and thighs.
Then—the tail.
A sharp twitch at the base of his spine made him gasp. Something long and flexible sprouted, furred and twitching with new nerves. It lashed behind him, restless, alive.
"Oh—oh fuck—"
His ears itched, then pricked—shifting higher on his head, morphing into velvety feline triangles. They flicked at every sound, hypersensitive. His fingers tingled, nails darkening into small, retractable claws. His feet arched, toes curling as they reshaped into padded paws.
But the worst—or best—part was the heat.
A deep, aching need coiled in his belly, his new sex throbbing, dripping. His tail lashed, his ears pinned back.
"M-mate—" The word slipped out before he could stop it. His mind was fogging, human thoughts dissolving into something simpler, needier.
The chamber door slid open.
Dr. Laura stood there, smirking, holding out a collar with a little bell. "Well, well. Look at you."
Daniel—no, not Daniel anymore—dropped to all fours without thinking, her tail high, her body burning.
"Meow~?"
Laura chuckled. "Good girl. Let’s get you to your enclosure. There’s a very eager tomcat waiting for you."
The newly minted cat-girl purred, her instincts singing. This was going to be purrfect.
