In Jenner's Quarters by @Kooshmeister (Bill Hiers)

How far is a mouse mother willing to go to save her children? Enough to become the slave of the one rat capable (she thinks) of helping her? Of dressing as he chooses and becoming his whore? That's exactly what Jenner is in the middle of trying to find out.

"How badly do you want to save your children, Mrs. Brisby?" the seductive voice of the rat hissed softly as he gripped her leash tighter. "If you submit to me and do as I command, I'll ensure that they're rescued from the tractor and well looked after here with us in the rosebush..."

She's allowed him to tie her up and dress her like a slut, and even put a collar and leash on her, but, for the sake of poor, sick little Timmy and the others, can Mrs. Brisby take the next step...?
