"Take my cock slut!  You KNOW what you are now!  TELL ME!  SAY WHAT YOU ARE!" Master screams...

"I'm your slut Master!  I love cocks and cum!  I am yours to use forever!  Fuck my ass PLEASE!!  FUCK ME MASTER AND MAKE ME A SLUT FOREVER!!"

Feeling Masters cock twitching, Kevin feels the spurts of Masters semen fill his ass, and his form lock forever into a female.  His new pussy orgasms and drools onto the sheets as images of pleasing men fill his mind, locking up Kevin and creating Kelley, Master's new slut he'll put on the streets.
