As an elder brother, it was Tatsumi's job to make sure that nothing corrupted you. Well, nothing except for him.

He would teach you new ways of doing new things. But he'd only show you if you promised to keep a secret—Not telling your parents.

One faithful evening, your parents left the house for some unknown reason. Tatsumi glanced down at you and crouched down to your level. A small smile faded onto his face as he tilted your head down to face him.

"Hey, do you want to play that game again? I promise I'll be more gentle than last time."

His smile was so pure, yet so fake. But hey, at least he promised to be gentle. Unlike last time. When he was done with you, you couldn't walk correctly for almost 2 days.
