As they drove away from school, Kendra had to fight the urge to rip her clothes off. She was burning up both with desire and also the impending feline transformation that she had been trying to hold back. Gripping the seat in front of her, she let out a loud caterwaul as her tail began to grow outward from her tailbone, curling uncomfortable under her dress.
Sitting next to, Tammy watched with fascination. She'd transformed plenty of times, but she'd never done so in front of a mirror or watched someone else transform. It was turning her on, especially with the feedback loop going on. Kendra's arousal made Eddie more aroused which in turn made Tammy more aroused.
Eddie desperately tried to concentrate on driving. Not on his raging hard-on. Not on the two girls in the backseat that he'd both had sex with in the last 24 hours. Driving. Get to Kendra's house first, and worry about everything else later.
Kendra couldn't take it anymore. She glanced at Tammy and was surprised to find her watching intently. Was she getting some thrill out of this? Kendra decided she didn't care and reached up under her dress, one hand caressing one of her lower breasts, the other going between her legs. Tammy was still watching and leaned over toward Kendra. The two girls looked at each other, each asking unspoken questions of the other. Then Tammy pressed her lips to Kendra's.
Eddie glanced in the rearview mirror and his gaze lingered a dangerously long amount of time. He forced his eyes back to the road, but wondered about the possibility of driving with one hand. In the meantime, he tried to drive faster.
More kisses followed the first. Kendra had never kissed another girl before, but Tammy had. She reached up and rubbed Kendra's ears, eliciting a moan. Kendra could feel the hair spreading over her body. The hand she had been using to caress her breasts went to one of Tammy's now pointed ears and soon Tammy's tail was sliding out under the back of her dress. The two catgirls soon moved their attention to each others breasts, each reaching up under the others dress to fondle ample breasts while their tongues danced together.
Eddie was never so relieved to arrive at someone's house as when he parked in Kendra's driveway. As soon as the car was off, he quickly confirmed nobody was around then turned to look in the back seat. The two catgirls were horizontal on the seat, making out and groping each other. Tammy was on top and Kendra's tail trailing off onto the floor. Both were fully transformed - tails, ears, eyes, claws, hair. Eddie had to take a deep breath to avoid blowing his load right there, but while he staved that off he felt his tail growing, uncomfortable now the second part of his anatomy uncomfortably confined by his pants.
"Kendra, Tammy, can we....can we take this inside?"
They stopped their fun and slowly returned to their seated positions, both breathing heavily. Sitting up revealing Kendra's dress had been ripped down the front by Tammy's claws, exposing her heaving breasts.
"We're here" Eddie said. "Let's get inside before someone sees us."
They nodded in agreement. Eddie got out of the car first, unlocked and opened the front door, and checked again to make sure nobody was around. He waved to the two girls who practically tumbled out of their respective car doors and sprinted for the front door, nimble as the cats they were, Kendra with her arms crossed over her chest to hold her dress together. Eddie closed and locked the door behind them.
The three stood for a moment in the living room, facing each other. Then Kendra released her arms and let her torn dress fall to the floor, revealing herself in all her feline glory. For the second time today, Tammy reached back, unzipped her dress, and let it fall to the floor. The two horny fully transformed catgirls stared lustily at Eddie, who realized he'd hit the jackpot as his transformation overtook him and turned him into a werecat like the others.
