Obey - Billionaire's Dungeon New Adult BDSM Romance, #3

When Becca arrives at billionaire David's estate for a third session, she's surprised to find Nick, a fellow submissive playmate, already in attendance. David lets her know that Nick has done something bad, that he will be punished... And that it's Becca who will be doing the punishing. There will be a strap-on toy involved, and a part of Nick's body that is familiar with being used for pleasure. Becca's innocent no more, but she's never done anything like this.
Still, Nick's eagerness to please has her heart beating fast. And of course, Becca must obey what Master commands.
