While I am happy to talk about this, or even issue tasks IRL I would prefer to roleplay. I said FM but it could be FF.

You have been together for a few years, but that is the problem, after a while you both eventually learn what the other likes and dislikes, the sex has become boring as you both wish to be more submissive so the dominant person gets bored and wants to switch. You both love each other and don't want to break up. Eventually one of you comes up with the idea to serve the same dom, to put out a post on reddit requesting one, each person posting their likes and dislikes, and what they think they want out of this relationship. Each wants to serve next to the other.

I would want to start at the beginning and work my way into your lives. Starting with just a few messages back and forth with as a group, and with each person individually before meeting up. The meeting place would probably be the house you two live in, where I can come and visit for the fun, or move into after a while to keep up the training, and submissive behaviors.

Another idea is you lost a timebomb. The flash drive you lost contained everything. Pictures of you two (clothed and nude), your phone number, e-mail, passwords to social media anything and everything to blackmail you with.

Or your Idea

This can be magical, or futuristic.
