The Schoolgirl and the Orc Battalion - Cool Odd-Eyed Yukino

Story

Just a little while ago... daily life at the young ladies' academy transformed in an instant into a world of slaughter and violation... Lady Yukino was grumbling to herself. "Tch, what the hell is this?" Men's corpses strewn all over the academy, and beautiful girls being thrust up into by ugly, pig-like orcs... The catastrophe unfolding before her eyes... She's desperately trying to accept the reality that her peaceful daily life has been turned upside down. Little Sae was sickly.

And no sooner had Sae barely managed to hide with Yukino than, before the two who blankly watch the door of the science prep room they'd hidden in being pounded on forcefully, there slowly appears... The current state: the lain-bare bodies of beautiful girls, pitifully exposed, violently devoured by ugly orcs and soaked in white cloudy fluid. Helpless against the orcs who merely swing their hips mercilessly, they are toyed with like dolls, ravaged, made to suck, and thrust into...
