男みたいだった幼馴染の犬になった僕。

My childhood friend, who used to be like a boy,
turned into a strongly developed gal when we met again after a long time!!

Even though she was supposed to just be an old friend,
the man’s sad nature can’t resist the charm of that grown-up body.

The childhood friend who was my only companion has now become my master.

Because she’s of the female sex, before I realized it,
the childhood friend who used to be like a boy has transformed into a sexual superior,
and this becomes an adventure game where you serve her.
