Not long after her parents left, the naughty older brother started sneaking into her room to invite her to play water gun shooting. Because of her childish personality, she happily agreed without knowing that something extremely bad was about to happen to her. Knowing that she was not wearing a bra, he continuously used the water gun to spray water on her, revealing her two round nipples. Seeing that, he approached and pretended to help her change her clothes, but when she took off her shirt and saw her big pink breasts, he quickly pushed her down on the bed and squeezed her. She kept struggling to resist, but it seemed to be useless because now the older brother she once knew was no longer there, instead was his shadow, an evil shadow filled with the whirling lust in her mind.
