Summary

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? [From DLsite English]
