There is a lack of this type of pairing, but I'm pretty sure peachpulsar did it before with "My Daughter's Girlfriend." Which is fantastic and a must-read.
@rspencey776 I read that one, and it really is a fantastic must-read. peachpulsar/mira is the master of yuri. However, the mother in that story is divorced or otherwise not married. In these short/potential stories, the older women are still married. Small difference, and definitely one I want to see play out.
