A yuri scene between Velvet and Eleanor from Tales of Berseria. Character references here: External External

As for the actual posing, this is a good starting point: External but a bit more from the side. Velvet should be on top. They should be locked in a deep kiss and Eleanor should have her arms behind Velvet's neck. Velvet should be holding onto Eleanor's ass to emphasize that she is "taking" her (one hand or both hands is left for the artist to decide). Both of their pussies should be wet and squished together, maybe a bit more than the reference picture. The scene should clearly express love and gentle passion.
