That's really something you'll have to work out for yourself violetgem- you don't need anyone to tell you it won't be easy!

It depends too on what your situation is- do you all live in the one house, or just what?

Do you have a pecking order- is one girl more important than the other?

Most importantly of all, do you all have good communication.....

Edit: That post by mastersgem sounds pretty much on the mark to me- I push my luck enough having a wife I live with & an online D/s relationship.
