Toy time

John was enjoying himself but the kinky part of him wasn't quite finished. He bounced Mel on his cock relishing her tightness and savouring the feeling of the warm water against their naked flesh. He was also enjoying something else, how smooth she was. Melanie was fast losing any hair not on her head. Her skin becoming smoother and less fleshlike every second. His little sister kissed him but as she did so John could feel her mouth becoming wider and less defined by the second. His sister was getting lighter, flesh and skin turning to rubber and plastic, her innards and body transforming into air. Her eyes, still vivid blue now displayed absolute arousal and surprised horror. The more he fucked her the less human his sister became. A living sex doll for her brother's immoral pleasure.

"That's a good doll," he groaned squeaking her fake tits as she squeaked around his cock her belly now bulging with each push. He loved the feeling erupting in her fake cunt. marking her as his property. Would he keep her like this? Explore her other holes? Maybe make her into a different toy.
