The Experiment That Got Away

I've been with Sarah for five years now, and we've always had an open relationship when it comes to exploring our kinks. Last week, I suggested we try something new, roleplaying as mentor and student in the bedroom... It started off innocent enough but soon escalated into something more intense than either of us expected... Now I'm not sure if this is going to affect how we view each other or damage the trust between us... Should we just let it go, or talk about it more? What do you all think?
