[Erimaki Kenkyuujo (Chlamydo)] Anata no Nioi ga Kieru made [SCANMTL]

An anxious demon girl with horns presents a seductive spell that promises heightened pleasure and a gradual transformation of a human companion into a succubus, as indicated by the dialogue about mana drain and sensitivity. The spell's chaotic activation unleashes tentacled sensations, causing the human to gasp and the demon to revel in the overwhelming climaxes and mana drain displayed in the panels. The tension escalates as the barrier shatters, the human's resistance wanes, and the demon taunts with mischievous laughter, hinting at a mind‑break scenario that culminates in an intense, shared sensory experience.
