It's so hard to find good representations of lesbianism in animation. Stuff for kids avoids it since apparently two girls kissing because they love each other are equivalent to people having their guts bursting out of them in the eyes of the censors. Adult works usually just use it because it solves the problem of having an "ugly" guy getting in the way of the action.
Still, there are good ones out there, and one of my favorites is the Lyrical Nanoha series, with Nanoha and Fate falling in love and, as adults, even adopting a kid, Vivio. They're a really tightly-knit family, and they have a lot of cute moments, which fanart thankfully honors. This here is an example of such, alluring on the adults, but the kid keeps it cute and reminds us that this is just an ordinary family. Just be careful not to get soap in her eyes, girls!
