I've also heard of it. It's essentially like a thruple relationship but it's lot harder to find people that are comfortable with that. Plus, from my experience little's in general tend to need more safety and emotional security, so I would think it would be harder to maintain those needs then a traditional relationship if trust is broken, even accidentally. If it's you're first time entering those kinds of relationships, it's more likely that accidental occurrence will happen, unless over communication happens to make sure everyone feels comfortable with all the boundaries and expectations before entering that dynamic. I would say if you're debating that look into thruples and see how they function before committing to that.
