I am a friend of a lovely lady who runs a fantastic rescue center, not to mention the many mousey people I know! I could probably foster a few myself as well.

I have to say take out the boys NOW! Also is your cage/tank suitable as a nursery cage? Any wheels should be removed and make sure there is plenty of bedding and different places for the girls to have their babies. Must say I am suprised you dont have more babies by now as mice are only pregnant for three weeks. My guess is sheer luck!! Also mice can get pregnant literaly right after they have given birth!

EDIT: Also dont be shocked to find them merging their litters into bigger groups or even eating their own, or others, babies if there are too many for them to cope with! It is possible you will have some deformed babies if your mice have gotten pregnant by their brothers, or some very small babies which may not make it. I hope none of this is the case though and any babies born are healthy and happy.
