## Description
I always liked my big sisters.
Not as sisters, but as women...

We were pretty young... we'd take baths together
and the girls would mess with my junk.
It was innocent, but it never really stopped.

When stress mounts, my sisters mount me.
They're experts at sucking my asshole and yanking me off.

One day I tried to confront them.
That's when we all learned the truth.

My take-charge big sisters are actually quite submissive... 

An incest adventure novel with two amazing onesans!
