It is not okay to involve children in this.
I’m not kink shaming, but bringing your kids into this is no longer kink. It is ethically and perhaps legally wrong to do.
As others have said, please keep this to your selves and allow kids to grow on their own without being overly burdened by the FLR dynamic between the parents.
Hello, you sound very interesting. Playful but controlling may be attributes that mesh well with my personality. Please send a note if I have piqued your interest. Thank you.
