The heroine this time is Makoto, a pretty average, if not well-endowed girl. The story starts with her getting confessed to during a sunset. She accepts the confession, but things don’t progress past a kiss that evening. Her newly appointed boyfriend walks her home, where we’re shown her adoptive brother looking at them from his window with an evil grin.

Meet Chisato, a seemingly typical young girl who only thinks of dating with her senpai. 
 
Normally a quiet, docile girl, she’s nevertheless going through her rebellious period and the target of her outbursts is typically her uncle. He’s distraught that the sweet little girl that always played with him has grown to be so foul-mouthed (though he doesn’t mind some other parts of her that have grown). 
 
One day, Chisato catches her uncle rummaging through her underwear drawer while she was not supposed to be around. Enraged, she lets out a torrent of verbal abuse and threats. 
 
Hearing that, the uncle finally snaps. Realizing that he’s beyond the point of no return, he decides to take matters into his own hands and take a more active role in his Chii-chan’s upbringing...
