Description:Mistress Nikki decides that her slave needs to be trained to be a good bisexual whore for her. The first step is trying to loosen up his very tight virginal asshole, as it will be needed for slut duties. Nikki fingers his tight hole before slipping in a small strap-on cock. The slave's hole is so tight that he struggles to take even such a small cock, so Nikki decides to focus on training the slut's mouth, bringing in a huge real cock for him to suck and worship while she fingers his ass.
