Why I Had Sex With My Older Sister
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?
True love and school life simulation with an immoral dilemma.
Freely enjoy the time between Golden Week holiday and Summer Vacation.
Study, pursue your personal interests, challenge various things.
Meanwhile, enjoy ecchi teasing with your big sister
and further your relationship with the girl at school.
Virgin loss, incest, assault, training, anal sex,
sex while pregnant, slave training, etc.
