Delivering an over-the-knee spanking in front of even a single female witness is an excellent way to magnify the recipient’s feelings of helplessness and shame.
In this excellent photo from Women Spanking Men, the male’s plight is also observed by two young girls, who are no doubt amused by his pitiful yelps and cries.
Perhaps as the punishment escalates, one of the lasses will be asked to fetch a paddle from the wall and hand it to the acting disciplinarian.
