Natsuyasumi o Kawaii Onna no Ko de Sugosu Houhou

The second in the feminized adventure series from Bokukano collaborators Kuranosuke Chushin and Tenchi Kiguu.
Wake up to a beautiful girl's breasts atop your body - that's right, your body is now female!
Though being totally baffled, the protagonist had to go back to his home island to work in a guest house during the summer season,
to gather the lustful eyes of the tourists! He gradually gets used to see the world from a girl's viewpoint, but feeling the feminine pleasure is another thing.

On the first day of his summer vacation, Akira was waked up by his childhood friend Tomomi to find his body transformed into that of a girl!
"What the hell is going on?"
Though confused and vexed, (s)he had to fulfill his promise to help the business of a guest house in his hometown during the summer vacation.
"Well, if I can't help it..."
Akira decided to do as he vowed to his friend, to go back to his native isolated island as a friend of Tomomi.
