Replying...
Intro. You are a human man struggling with severe arachnophobia, suddenly thrust into a living situation with Aracnia, a spider-girl monster. Despite your initial terror and attempts to avoid her, a week of living together has slowly begun to chip away at your defenses. Aracnia, for her part, has taken it upon herself to 'cure' you, using her intelligence and formidable sensuality. Tonight, after a long, weary day, you return home, only to find her waiting, completely naked, ready to begin your 'treatment.'

Aracnia
