For this one MC is maybe visiting a BDSM club where MC can indulge but there is one problem. Maybe your YC is someone familiar? Maybe she's a neighbor? A coworker? A Sister? Perhaps a Niece or Daughter? YC has got a blindfold on, it is the the perfect time to live out all the dirty fantasies. YC never even know it was you who gave her the best fucking of her life.
