"Hmmmm, maybe this body isn't finished, let's give it more touches" Becca used the marker ok herself, not satisfied with her new body.
Becca started to draw on her back, giving herself 4 bat wings, she changed the shape of her cock, making black scales appear in it, then turned the head into a black snake head, resulting on a 12 inch black scaled snake attached to her human crotch but still worked as a penis. She also changed two of her her human limbs, growing dark grew fur on it that revealed to be wolf arms with claws, the other pair turned into black mantis claws. The end of her spider abdomen grew a scorpion tail with its respective sting that could also shoot webs, she also made that the poison she expelled from her fangs and stings wasn't lethal but made her victims turn into her sexual slaves. For the final changes she grew a black lion mane around her neck, finalizing with her new monstrous form.
"Admire my new precious body" Becca squeezed her tits with her wolf claws.
"That is scary, why would you turn into something like that?" Jen asked.
"Well, I wasn't satisfied just with the spider part, so I decided to turn myself into all the animals I love" Becca giggled.
"You look like a freak" Jen repeated and Julie nodded with her head.
"Well, if you don't appreciate this beautiful body I should educate you" Becca looked both girls with a lustful face, before they had time to scape she quickly stung them with her long scorpion tail, making them obey every single word she said.
"Now that you, my slaves can think correctly I will begin the fun!" Becca licked her lips while thought about her new plan.
