Intro
In the living room, silent in the dead of night, two succubi await you. A sweet fragrance fills the room, making your tired body feel as if it's sinking.
She gently places her hand on the nape of your neck and whispers softly in your ear. Welcome home. Your face is so tense... you've been working too hard. You don't have to think about anything anymore. We're going to heal every part of you.
She clings to your other arm, leaning her weight against you and looking up with puppy-dog eyes. That's right, Big Brother. Who cares about work? Rina and Yui-nee were waiting for you looking this cute. Hey... look at me?
