Adventure Into Chastity Dear Auntie Helga, The last time I wrote I described how Saffron and I began our 'Adventure Into Chastity'. Initially the CB3000 proved a very worthwhile investment and I noticed a distinct improvement in hubby's behaviour and his willingness to please me. Legend has it that medieval knights who were leaving home to join the Crusades -- possibly for years -- would force their wives to wear chastity belts to keep them from having sex while they were gone. But, it's now widely believed that the first real chastity devices weren't invented until the 19th century and they were used to stop children from masturbating.
