A new chapter in the slave's bisexual journey begins as Mistress introduces him to his first cock. In her femdom-pov, she humiliates him, making him worship her high heels, then forces him to service another man, his cock in his mouth, her commands echoing through the room. She watches, relishing his humiliation, then takes over, riding the other's cock while forcing the slave to lick her clit, training him in his new role as her bi-sexual slut.
