You were an inflatable sex doll just like Bryan. Instantly Matt felt himself getting lighter. His skin is rubbery, and his body begins to swell. He is growing taller and more muscular. Catching a glimpse of himself in the mirror as Don shoves his cock in Matt's rubbery rear, Matt sees that he has become Bryan's identical twin. Don sits on Bryan's rubber dildo prick impaling himself as he pumps his body up and down simultaneaously stimulating his cock in Matt and his butt on Bryan.
"Double my pleasure, double my fun," Don chortles.
He is lost in ectstasy and does not hear the footsteps or gasp of the person who walked through his open door.
