This happened in Massachusetts, USA. My question is, why did she have sex in front of five people with recording devices, instead of somewhere in privacy?
Where did you read that she had sex in front of five people? They were somehow involved in recording and distributing the recordings. They did not have to be present to do that.
According to former Lowell Mass resident, Jack Kerouac, such things are not uncommon at a yab yum, no matter how sloppy it may be.
