FANZA和Melonbooks上是[もちもちたいよう (森田♀ハニー)]
但我是DLsite买的，上面是[ふわふわソーダ (森田つみれ)]，我就这么写了
On FANZA and Melonbooks, it's [Mochimochi Taiyou (Morita Honey)]
But on DL, where I bought, it's [Fuwafuwa Soda (Morita Tsumire)], so wrote I.

[Synopsis]

The story begins with the heroine's past and despite enduring countless humiliations from her father, she is now once again a commodity... a plaything for other men.
Sensing something strange about her older sister, the younger sister sets out to help but is defeated and ends up following in her sister's footsteps.
