Contracting of FW

If a free woman would assure herself of her man’s love, she could not do better than, in effect, become his slave. She can beg of him, if she senses in herself the true bondage of love, an enslavement ceremony, in which she proclaims herself, and becomes, his slave. In their most secret and intimate relations thereafter she lives and loves as his slave. If a woman fears to do this she may, on an experimental basis, resort to limited self-contracting, in which her documents will contain stated termination dates. Thus, by her own free will, she becomes a slave for a specific period, ranging usually from an evening to a year. The woman enters into this arrangement freely; she cannot, of course, withdraw from it in the same way….
