Eventually, she found the instructions. "WARNING: Do not take off any individual part of the catsuit. Doing so will make the outfit impossible to remove safely."
Selina panicked. She was now trapped into this latex suit, and she was terrified. How was she supposed to live her life as a cat?
Then it hit her. She flipped through the instructions, but there was no mention as to whether or not putting the mask back on would allow her to remove the suit. Still, it was worth a shot.
Moving around slowly and quietly (not difficult since her hands and feet were now covered with soft pads), Selina managed to find the mask and put it back on her face. But when she felt for a zipper, she felt a tremendous flash of pain shoot down her spine, causing her to yelp like a cat. Her boyfriend, still asleep, woke up.
"Selina, what's happening?!!"
"I don't kno-" Those were the last words she spoke before a fine coat of black-grey hair began to sprout from the latex and cover her body. Before the mask merged with her face, leaving her with whiskers, a cat's nose, cat eyes, and ears perched on the top of her head.
Selina stood up in horror. She thought of that one episode in the original Batman cartoon where some mad scientist had turned Selina Kyle into a literal cat-woman. Now she knew what that felt like.
"Selina, you're a cat!!!" The boyfriend jumped out of bed, his hands held in front of his face.
"Mark, please...please don't be afraid. Please don't leave me." Selina's eyes were incapable of shedding tears, but the pain in her voice was enough. Mark let his guard down. He ran over and threw his arms around her.
"I'm a freak, a monster."
"No, you're still as beautiful as the day I met you, Selina. We'll get through this." He tried to force a smile. "You know, I always had a bit of a fetish for girls with tails and fur."
"Really?"
"Really. Mind showing me just how freaky a cat woman can be?"
Selina, overjoyed, practically threw Mark onto the bed. She could feel him getting hard as she rubbed her fur against his crotch. Eventually, she let him slide right into her latex pussy.
"Selina, you're so soft! My dick's gonna burst!"
And it did. After a few minutes of hard mating, Selina felt her boyfriend ejaculate, releasing all of his sperm into her. It went on for a few glorious seconds. But then Selina noticed that Mark's cum kept flowing in.
"Mark, I think you need to pull-"
The yellow eyes of a fierce cat man stared right back at her.
"No, I'm not finished, Selina." His balls, covered with the same black-grey fur, were pulsing furiously as they churned out more sperm. And Mark, with his powerful new muscles, kept Selina from getting off. And his cock didn't feel soft anymore. It felt long and squishy, almost like it was made of...latex???
"Mark-"
"Shut up!!! Take the rest of my seed, Selina!!!"
With one thrust, he sent a river of semen right into her womb. Only then did he pull out. His latex dick remained hard as a log, with drops of cat sperm dripping from the tip.
Selina felt nauseous. Mark's sperm was already fertilizing her eggs. She was going to have a litter of kittens soon.
