Eddie and Kendra both felt entranced, unable to take their eyes off Tammy's/Tommy's erect cat cock. They felt warm as the fur began to spread on their bodies. Eddie felt cramps unlike anything he had ever had before. He staggered to Kendra's bed and collapsed there, clutching his stomach. Something felt very strange, and his chest and crotch felt warm. Eddie fumbled with his clothes, trying to undress as he struggled against the gutwrenching sensations. Kendra's transformation felt normal, but she was worried about Eddie. When Eddie finally got his shirt off, he found his chest seemed swollen. Kendra touched it, and Eddie realized it was very sensitive...almost like... Kendra and Eddie exchanged a glance and knew they were thinking the same thing. They got Eddie's pants off and found what they had both expected by that point.
"I'm turning into a catgirl!" exclaimed Eddie.
Eddie the catgirl turned to look at Tammy the catboy. Eddie's mind told him this was all wrong, that everything was backwards. But her transformed body told her otherwise. Eddie felt Kendra's hands on growing breasts, all six of them.
"Is it wrong I want to watch this?" Kendra asked as she nuzzled her boyfriend-turned-catgirl.
Eddie felt warm and wet. Kendra positioned Eddie on the edge of the bed, legs spread wide, as she continued to caress and nuzzle.
"Tammy..." Eddie said, the longing evident in his voice.
Eddie felt penis slide into vagina and the barbs take hold. Kendra released Eddie, sliding over to the corner of her bed and began masturbating as Tammy thrust into Eddie. Now Eddie understood why Kendra and Tammy had been so eager for this. It didn't take much to push the new catgirl over the edge and soon Eddie felt another strange sensation as Tammy's seed spread into him.
