Nina Hartley here with guest Sarah Blake, for Lesson #105: Submissives are Fun! Sarah lets me put a collar on her, and does whatever I want her to do, for an entire hour-plus chat with our fans. My fans know me, I'm one mature pornstar who still needs to get off, every day if possible! Sarah is a smart cookie, and if she stays this horny, she'll go anywhere she wants in this industry!
