Kyonyuu Fantasy 5 -Ouji Leen | 巨乳ファンタジー5-王子リーン-

The protagonist, Lean, is the third prince of the Regalia Kingdom. Although a legitimate prince, he is excluded from the succession race because of his mother's questionable origins.

Upon turning twenty, he is dispatched as a count to the borderland, the Barony of Bolondo. On his way to Bolondo, Lean encounters a female sorceress who has lost her donkey and is stranded. Lean gives her his horse. In return, the sorceress gives him a "magic lamp".

It was said to be something to use when he felt lonely… but instead of a wish-granting lamp, it was a convenient item that summoned succubi, famous for being dancers.

Summoned by the magic lamp was a succubus daughter—Berber. Lean's fate begins to change drastically with his encounter with Berber…
