I recall a story of a girl traveling with her friend (for safety) to meet an online male Dom in real life "finally"
The "safety" friend says she doesn't have anything to do during her friends "weekend long session" so out of bordem she says something about taking in the sites while on vacation.
What is supposed to be a long weekend of bdsm meeting her friend afterwards to travel home
... turns out much worse for the girls
Male Dom reveals the safety friend has been in bondage and he keeps both girls.
(consensual turns noncon)
Does any of this ring a bell with anyone?
