History grad James Sheridan thinks his biggest problem in life is trying to find a suitable outfit for his upcoming Ph.D. candidacy exam. That is, until he accidentally texts a changing-room selfie meant for his fashionable sister to his ex, the domineering Professor Carson.James and Carson haven’t seen each since James fled their power games two years ago. Back in his undergrad days, Carson was his Professor, and not just in the academic sense: a man of unusual tastes and extreme sexual demands, James had been happy to sate Carson’s savage appetites. Too happy, in fact. He never could trust himself not to let Carson push too far.Now James is older and wiser, and sharing some seriously flirtatious vibes with a cute menswear rep. When Carson replies to James’s errant text, ready to pick up where they left off, James can’t help being drawn back into Carson’s control. It’s only when Carson suggests involving the salesman that James has to ask himself how far is too far, and whether he’s willing to go there with Carson again.
