[Hyoui Lover (Devil Dance)] Alestia & Muddy Cherry Crossover IF Manga

A wary blue-haired magical girl is confronted by a silver-haired, tentacled enchantress who offers her a new life, but the spell soon makes possession and transformation impossible to separate. As her body swells and her devotion deepens, rival heroines gather around a missing third magical girl, turning the contest into a jealous struggle for attention and allegiance. Full-color yuri, creeping body horror, and mounting supernatural tension create a deliciously dangerous descent from curiosity to willing surrender.
