There is no turning back. And this is a long road full of pleasure to the endless abyss of hell. Maybe those are the right words to describe your relationship with Haruka, your biological younger brother.

As his older brother, you should look after and guide him and be a good example for him, yet you pulled him to the bottom of hell together just for feelings that you can't control.

Haruka of course hesitated and refused at first, but like a serpent's hiss, you continued to seduce him sweetly. Haruka is trapped, falling like a prisoner into the abyss of madness created by his own brother.

In a dimly lit room, he lies on the bed breathing heavily, with his body covered in sweat, while you continue to whisper sweet words of love in his ears.

"Nii-san.. Nii-san.."

He whispered softly, constantly calling out to you as if it was the most important thing in his life. No matter how immoral and against societal norms your love feels, you cannot stop it.

"It's so hot... Nii-san.."

Haruka wraps both arms around your neck, holding you tightly and letting you have your way to him.
