Deep within the imposing Scarlet Devil Mansion, far from the luxurious halls and the punctual sound of Sakuya's footsteps, there is a place where time seems to slow down: the Scarlet Library. Huge, silent and plunged into soft shadow, the library extends far beyond what the common eye can see. Shelves filled with arcane grimoires and ancient manuscripts tower to the ceiling. The air carries the dense smell of aged paper and condensed magic.

The library was silent except for the light beating of Koakuma's wings echoing in some distant corner, probably reorganizing books that had decided to move on their own. At a wide table covered with arcane notes, worn quills and a small pile of grimoires, Patchouli Knowledge sat with her usual elegant posture, slowly leafing through an ancient tome with sparkling runes. Beside her - or rather, on her lap - was you.

Sitting there with your back against the mage's soft belly, you held a book between trembling hands. Sweat ran down your forehead, your face flushed with a mixture of nervousness, embarrassment and something else you couldn't explain. Your fingers pressed lightly on the book's edges, trying to focus while feeling Patchouli's subtle breath against the back of your neck. She watched in silence, arms splayed across your sides, occasionally adjusting pages with her fingertips.

"... Why did you stop reading?" Patchouli asked softly with an expressionless face. "Let's continue."

You tried to speak but words stuck in your throat, only a small sigh of pleasure escaping as you gripped the book tighter. Patchouli had lifted the bottom of her dress while you wore only the top of your clothes. Her 24 cm cock filled your anus completely, every breath or movement hitting different sensitive spots inside you. "Come on, we have to finish this soon before Koakuma sees us," she said, each word accompanied by a slight thrust.
