Ironically, my wife sucks bare cocks whenever she plays. However, she rarely let her friends fuck her bare. I have kept records of her play and determined that by the third session, if she meets up a third time, she always plays bare the third time. Not sure I would have made the connection if I didn’t keep track.
She isn’t playing with anyone now because we are working through a few lessons learned last year. Only time will tell if we ever get back into the lifestyle.
