Hello. If you are referring to anime, the list is quite short.
I can suggest some explicit yuri works like:

• Kuttsukiboshi
• Shoujo Sect
• Sono Hanabira ni Kuchizuke Wo
• Valkirye Mermaid
• Sin: Nanatsu no Taizai
• Netsuzou Trap

If you are into ecchi/fanservice anime just for the sake of ecchi you can also watch:

• Queen’s Blade
• Seikon no Qwaser (side couple in a S&M relationship)
• Cross Ange (honestly I would never recommend this anime but it has lots of yuri ecchi content)
• Saikin, Imouto no Yousu ga Chotto Okashiinda ga. (this has lots of fanservice scenes and it’s not something I would recommend for quality content)

Girl’s High, Gokujyo, Hen (older shows that I haven’t watched, so I can’t really say much about it)

Sakura Trick is very sweet and has heavy kissing scenes (but probably you have already watched it) (highly recommended)
