Sis x Para -Sister Paradise-

"Thanks to you, big brother, I can attend that school. You can do whatever you like to me."

With the onset of our parents' business trip, my sister and I have lived together.
Within the months and years that have passed in our parents' house, I've seen my sister become grown up.

(Sis, you've gotten this cute?)

It's been years since I've seen my sister's sleeping face.
My heart begins to flutter for that sleeping face, which faintly drifts with loveliness.

---

Tormented with the weight of the crime I've committed, I head to the kitchen where my sister, who always seems the same, is preparing breakfast.

"I guess you were tired. Not just from school, but from your part-time job and my own welfare."
"So until you can get a girlfriend, big brother, I'll give you myself instead."

From this time on, the story of the strange life of my sister and I begins.
