True love and school life simulation with an immoral dilemma.
Freely enjoy the time between Golden Week holiday and Summer Vacation.

Daily life was peaceful but busy:
You were deeply involved in school, and were dating a transfer student.
Then you had that sweet, dangerous night with your sister.

The secret thrill led to another incident. And another.
Each day the perversion escalated a bit more.

Two heroines, two lives and developments.
Forbidden incest and a dream school life.
Which will you choose?
