In the animated world of Yuri and Rucka, these two schoolgirls find solace in self-pleasure. Yuri, with her long, dark hair and innocent eyes, tentatively touches herself, her fingers exploring her young body. Rucka, her best friend, watches with curiosity, her own hand slipping beneath her skirt. Their masturbation session is interrupted by a knock at the door, but they quickly hide, their secret safe.
