[Match Hakase] Jinken Hakai Koujou ~Kanzen Hakai Manual~ [Penguin Piper]

A panicked woman is thrust into a living machine that floods her with relentless tentacles, promising a 'complete destruction manual' as she fights to survive the invasive assault. The tension escalates as the device's cruel design turns pleasure into pain, forcing her into bondage and anal torment while the surrounding apparatus records every forced reaction. The story blends graphic bondage, anal, snuff, and tentacle themes into a chilling atmosphere of mechanical domination and forced submission.
