リリス&リリム

Legendary Succubus Sisters that were sealed 500 years ago by a Hero. Incredibly strong Succubi, they are treated by other Succubi as their savior. Top-class Succubi, they work together to indulge a man in ecstasy. Entangling their bodies together with the man’s, they take turns mating with him all while rubbing their bodies against his. To tell them apart, the older sister with smaller breasts is Lilith, and the younger sister with larger breasts is Lilim. The two consider themselves of the same flesh, and cannot bear to part with the other for longer than a few moments. [From In-game Monsterpedia]
