In general, freedom is worth a lot. So, if a common mature friend divorces her husband, then close friends simply cannot fail to celebrate this event. In order to celebrate, women go to Vegas and rent a room there for cool relaxation. Nearby men flock to drunk women like flies to honey and soon a private bachelorette party turns into a gorgeous group sex. And if someone says that there is only drunkenness and debauchery, then it is not so. Its just a great way for a divorcee to choose a new husband ... well, or at least a lover!
