looking for GMILF

[kk2extreme]

MILFs are common, but awesome looking GMILFs are rare, e.g.

Spoiler for clannad after story:

sanae

any GMILFs with quanlities that match clannad's

[Guardian Enzo]

Ah, Stacey's Mom, eh? Isekai no Seikishi Monogotari might fit the bill, though as with any Tenchi series the issue of just who the GF is is never an easy thing. Kare Kano springs to mind as well.

By GMILF do you mean grandmothers?
If that's the case this women has a daughter with an adopted daughter.

This is from Mahoraba Heartful Days

Their is also Miko Shibuya from Kyo Kara Maoh who has a son with an adopted daughter but this might be cheating since he's not old enough to be her real mother.

There's one in Abenobashi Mahou Shoutengai, though by telling you that I just spoiled the entire story.
