These ladies all seem to be amused or entertained by the helplessness of their chastity slaves. I can hear them laughing out loud as they make a victim's plight worse and his chastity longer... and longer.
Well, at least two of them are amused and entertained by the helplessness of some OTHER girl's chastity slave. I'm quite interested in the whole idea of when does a girl reveal to her girlfriends that she keeps her boyfriend's dick locked up. Hmm, actually I could also explore when a girl decides to reveal to her girlfriends that she keeps a guy's dick locked up when he ISN'T her boyfriend ... interesting concept.
