Just read a pretty new book called "Male Chastity Play for Modern Lovers". You can get it on Amazon Kindle. It is a good book, very good for vanilla wives. It talks about using male chastity in a loving way to help husband not masturbate and have a more loving relationship with his wife. It is not written like BDSm or being cruel. Good read for someone newly interested in male chastity.
It seems there a number of chastity and or submission related titles available free to those with a Kindle and a Kindleunlimited or also on Audiobooks account or subscription whatever it is. Is anyone in a position to comment on any of the available titles ?
