Hey there, I think a new rule either a dom having you as their pet and you domming a NPC, I think it would be nice where there is a rule to either limit you or the NPC to be able to fuck and have relationships with others.
Like the Dom NPC set a new rule to you that only said NPC will be the only one fucking you and no one else, and there will be punishment if you dont follow, of course if she knows.
Same goes for your submissives.
