You go in for routine outpatient surgery; little thing on your leg that your dermatologist wants lopped off and biopsied. They'll do it under light sedation; you'll be home in time for dinner; no big deal. And then . . . When you "come to," in post-op? You know immediately that . . . a little more than skin surgery has been performed on you. You can feel it: a sting, a burn, a subtle lump . . . in a part of your body that shouldn't be lumpy. Your wife? She's simply-terrifyingly!-radiant. Now? She has a phone app that both lets her read your . . . physical state and behavior, AND allows her to administer . . . corrections-which turns her on to just a frightening degree. Plus-the pain and humiliation notwithstanding-there's also some part of this that . . . turns you on, too.
