My little sister has loved me since we were little. As time passed, her body became voluptuous, and she grew to have huge G-cup breasts and a huge ass. She shows off her plump breasts defenselessly, revealing her cleavage, her nipples, and her panty lines. Is she trying to seduce me? Or is she just a natural? I can't stand the sight of her, so I attack her. Raw sex, titty fucking! She gently begs me to cum inside her, saying, "Big brother, cum inside me...", and I lose my reason and cum inside her vagina every day.
