@Dawnaxis said in Yuri Advice:
Seriously Seeking Sister! Ultimate Vampire Princess Just Wants Little Sister; Plenty of Service Will Be Provided!” as yuri, but I haven’t read them yet so I can’t comment any further.
It's a good story, but much more like Kuma Kuma Kuma Bear or FUNA's Abilities Average than Sexiled. You can probably find a yuri subtext if you look hard, but it's low key.
