[Hirowa Nagi] A Moment of Carelesness Brings a Lifetime of Pleasure ([Anthology] Inyouchuu + Inyouchuu Shoku) [Kuraudo]

When a shy schoolgirl’s suppression charm cracks, a parasitic worm bursts from her exposed anus, turning a simple slip into a night of relentless, worm‑filled torment. Bound and helpless, she endures the writhing invasion as the charm’s effect fades, driving her into a frenzy of pleasure and pain. The surge of the parasite delivers an orgasmic climax that fuses terror with ecstasy, leaving her forever changed.
