Otoko Mitai Datta Osananajimi no Inu ni Natta Boku.

Synopsis

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.
