Intimate Days with My Tsundere Sister v.1.0.1

She and I are left utterly alone in our quiet house.
In the dead silence of the residence, a sweet, dangerous tension begins to thicken the air.
She, usually so cold to me, reveals a completely different side of herself when it's just the two of us at night.
Her lovely sleeping form, wrapped in loose pajamas... The soft swell of her chest and smooth, white skin peeking out--the sight makes my groin ache and my pulse hammer in my throat.
With every one of her defenseless, sweet breaths, the forbidden desires I'd long suppressed began to throb with a raw, desperate need.
