Mistress never made it with any of my or our friends. We always tried to keep her adventures discrete and distinct from our "normal" lives. Curious of any of our readers have gone in that direction. We do have a friend here who we've speculated about as a potential partner for Mistress. But a number of reasons have kept us away from that.
As far as the "morning after", I was always happy to serve coffee in bed to Mistress and J when there was a sleepover. Crazy turn on form me.
