They Were Happy to Become his Willing Slaves!
Frank and his wife Tami enjoyed living the alternative lifestyle of bondage and domination: he as dominant and she the submissive. Then Frank seduced two other women, Colleen and Zoe, and turned them into willing slaves.
This was easy, despite the fact that both women were married. But their husbands wouldn't engage in oral sex or role playing - anything but straight, missionary position sex - so both women were more than eager to serve Frank in any way he demanded.
But it had always been his goal to return Zoe and Colleen to their husbands - once the two men learned the necessity of fulfilling a woman's sexual needs and how to fulfill them! See, Frank had a special plan: one that would turn the husbands into masters, and have their wives happy to tell their husbands: "You own me!"
