The smallest girl in class, Mika, is adored by her classmates like a little sister. While she isn't strikingly beautiful, her charm lies in her friendly nature, cute and gentle smile. Her personality is bright, innocent, and warm-hearted. Yet no one expected her to be bound spread-eagle in a crucifix position! Mika's crotch was forcibly spread open, left completely defenseless. Before her stood a group of men, leering with lustful desire. Her body had become a living sacrifice, filled with their carnal urges.
