Tell her about the book, but ask for it back

Grinding your teeth in frustration, you consider the options. You definitely don't want to just give her the book- you really wanted to sell that. The question was whether it was worth more than your armor and weapons- you obviously weren't about to just let her leave you there, naked and defenseless. You couldn't help but also consider what she could do with the book - it didn't appear that there was anything related to combat prowess, but there might have been something more useful in there, your mind thinking back briefly to the final page.

"M'lady, I believe that the enchantment latched onto the occult book I grabbed from deeper in the cave - A leather bound tome with silver filigree." You let out an audible sigh, still going back and forth in your head between your clothes and the book, but eventually give in to your greed. "Use it as you wish. I want it back when you're done though."

A glint goes through the old hag's eyes, excitement spreading across her face. "Oh, ho ho ho, you found Gil's old grimoire? Now that is quite the prize! Ten minutes is more than enough for me, I'll be happy to let you go with your prize and clothes afterwards- maybe you'll even enjoy the show!"

Waving a hand in the air, the witch conjures a glowing, purple circle, floating in the air in front of her. Reaching in a single arm, the circle almost appears to cut off her hand and wrist, but she still moves around her arm as if rummaging through an unseen space. "Ah ha!" with a quick exclamation, she retracts her arm, which reappears with the book in tow.

"Now, then, let's see about these ten minutes. Feel free to take a seat, if you'd prefer." More purple magic flows from her arms, the tome suspending in the air in front of her, rapidly flipping through pages until she settles on the one she wants. "Time to reclaim what time has stolen from me!" A massive smile crosses her face as she begins the incantation, the words flowing outwards. tirips ruoy mialcer, kcolc eht kcab nrut

Bright red and purple sparks combine to encircle the witch's body, her form lost in a mist of colorful magic. You hear her loud cackle throughout the process, but it seems to shift, becoming much clearer and brighter in tone. At one point, the rags that she was wearing fly out of the whirlwind, landing on a rock near you. After almost a minute, the storm starts to slow, and you watch as a young woman walks out, no older than her early twenties.

She's about the same height and build as you, slender but well curved, with long, flowing blond hair. Her face is best described as beautiful, fair and well-rounded, and her skin is fair but slightly tanned. As expected, she's also completely naked, and her breasts are just slightly bigger than your own, with pleasant teardrop shapes and topped by a pair of puffy nipples, the areolae extending fully from the rest of the skin. Her eyes, however, confirm that she is the same witch who stripped you, as they're the same bright, piercing green. The book continues to hover in the air in front of her, suspended by the same purple magic.

"Well, that's much better, don't you agree?" she asks, twirling around in a circle as if showing off.
