魔界プリンセスフィリーネの優雅な搾精ライフ～打ち止めなんて許さないわよ～

You died while protecting a voluptuous girl from an incident.
She turned out to be the princess of the spirit world, and wants to extend her help to you now, if you will become her manservant.
What that means is, she will live upon your sperm!
Your new life as a pleasured cum-giver from morning to night begins!

[From English DLSite]
