Touma Ninden Haruna to Maya ~Inshokuchuu ni, Kunoichi Otsu~

Two kunoichi sisters headed off into enemy territory to asses the strength of the enemy troops.
However, they were ambushed by the enemy shortly after infiltrating their lands.
The sisters had been through countless battles before, but the enemy shinobi were simply too many, and they were captured before they could fight their way out.
Their enemy was not dumb, they realized that they could use both the sisters' strength, and the information they held. And thus the interrogation began.
And thus, the trampling of the two kunoichi began...

The actions were numerous and neverending. Assault, violation, gangbang, inter-species violation...
Will there be an end to the sisters' torment...?
