"This is so...weird..." said Ethan.
"But you're okay?" asked Ava.
"I guess so. As okay as you can be after being unexpectedly turned into a catgirl."
"Do you want to try out your new body?"
"Huh?" asked Ethan. Then it occurred to him that Ava's hands were still on his chest. "Do you have a lesbian catgirl fetish?" Ethan asked, surprised yet aroused.
"Not that I was aware before, but I might now" Ava said with a sly grin that she punctuated by caressing Ethan's breasts, which elicited a moan.
Ethan leaned in for a kiss and soon the two catgirls were caressing each other's bodies, hands roaming everywhere for several minutes until Ava intentionally slid off the bed. She spread Ethan's legs wide.
"This is your first time like this so this is my treat for you" said Ava. "But you owe me one." She slid down Ethan's body to his crotch.
"I could take care of you when you're done with me" Ethan offered.
"Oh no, I don't think you'll be in any condition to do that."
Ava tongue slid into Ethan and he soon realized she was right. He couldn't imagine what this was like until he experienced. Ava meanwhile slid her hand down to her own crotch and began fingering herself, slowly building up her own climax as she drove Ethan to one. Waves of pleasure swept over Ethan's body until he began to shudder and finally let out an inhuman sound before collapsing on the bed. Ava followed shortly after him, collapsing on the floor and breathing heavily. She found the energy to climb back onto the bed and nuzzle up to her feline lover who had already dozed off. As Ava faded off to sleep she thought about the ways her and Ethan might have fun as catgirls. Then again, part of her wanted Ethan to mount her.
Sometime later, Ava was the first to wake back up. She examined her body and found herself back to normal, but when she wrapped her arms around Ethan she found him still covered in fur. Her hands explored Ethan's body and confirmed what Ava suspected: while she had regained human form, Ethan was still a catgirl! Had her bite caused a permanent change?
