He thought he was onto a sure thing and he would soon have these two beautiful women running around after him as his slaves - their forfeit if they lost the bet!
He agreed to let them transform him and pretty soon the things they were doing became more and more permanent. They were turning him into a hot trashy she-male slut and there seemed to be nothing he could do to stop it.
It didn't take him long to realize that he was going to lose. It wouldn't be the two women as his slaves, it would be him as theirs! They would have a pretty female slave running around after them!!
