Mahou Shoujo Naiti Miruku Nakama ni Uragirare Shokushu no Toriko [Project Valvrein]

A pure‑hearted magical girl, Naiti Miruku, is violently seized by a tentacled monster that bursts from her rear, forcing her into anal intercourse and overwhelming pleasure as she battles to retain her holy resolve. The chaotic scene shifts to her companion Cocoa‑chan, who is similarly overwhelmed, her body contorted in ecstatic agony while the relentless tentacles pump and squirt, driving her toward an intense climax. Ultimately, the struggle culminates in a desperate attempt to purify the corrupted energy, culminating in a vivid ahegao finale that blends double penetration, impregnation, and the raw intensity of magical girl heroism.
