'Legacy Sentence'. What a great term. And what a terrible fix to be in. At the mercy of any girl who knows your secret. If she decides to loan you out or offer you for rent, tough luck chastity boy. Imagine having to spend a weekend serving a strange girl or two, your services exchanged for a bottle of wine or the price of a large pizza.
Well, 'Legacy Sentence usually means the victim is no longer in contact with the girl. But letting out the victim's services is an interesting idea ... may have a look at that in the future.
