女系家族の犬になった僕

Yuuki Shimazaki finds himself in the care of an all female household after his parents die.
They all seemed so kind at first, but something perversely changes.

He can't help but lust for them. Their hot bodies, their beautiful legs and arms, hair, clothes, even their excretions. Pride lost, he can only find excitement in the different in level between himself and them. No matter how hard he works, no matter how much money he has, it won't measure up.
