She couldn't believe she was actually doing this...but in the moment, her curiosity overrode her embarrassment. There it was on the shelf: "The Illustrated Guide to Pleasures of the Flesh." The spine was cracked...it looked well-used. She shuddered, but after glancing to see if anyone else was around, she reached for it anyway...
As she picked up the book, something from behind it fell forward with a rubbery plop. A dildo...someone had "booby-trapped" the book to reveal a big, purple dildo. Gross...as if she'd even touch it without knowing where it had been...
She turned her attention to the book. Even the cover illustration made her blush. Again she looked around to make sure no one was watching...she flipped it open.
Right from the start, on the mostly blank dedication page, the book had been defaced. Some juvenile idiot had scrawled "U R A PIG" in marker across it. "No I'm not," she said aloud, quietly. "I'm just...just curious...and horny..." As she thumbed through it, she was surprised the library had even kept it in this state, pages were torn, some were stuck together, the faces on the lurid drawings were circled or X'd out...still she continued, almost feeling ravenous for more of what she was seeing...and initially oblivious to the changes taking place in her body...
By the time she noticed the bulbous snout before her eyes, it was too late...she gasped and flung the book aside, looking down at the bloated ruin of her body. She squealed, then remembering she was in a library, instinctively lowered her volume to a concerned grunt. Whether it was due to the pictures she'd been ogling, circumstance, or some unknown magic...almost without thinking, she snatched up the dildo and plunged it into herself, her eyes rolling back into her head in confused ecstasy. She dropped to the ground and began rocking back and forth, reveling in the new sensations, unable to focus on the horror of the pig creature she'd become, or to wonder how she might change back...
