You decide that stealing the book will be easier and faster. The paths to the mountains are dangerous and full of terrible creatures. However, the road to the farms is close to the city, and there are no monsters around.

You also have the element of surprise, and the wizard trusts too much in his invisibility shield.

You memorize the map and start your journey to the south, walking for almost the whole night. You arrive without any issues.

You stay awake until the first rays of sunlight strike the stones of the tower, and you finally see it: a huge tower, visible for only a few moments, just enough time to get inside through a window.

You maybe didn't know... but stealing from a wizard is hard, very hard.
As soon as you climb through the window, your body starts to move slower. Something is affecting you... some kind of spell.

Then, a giantess notices you. She's slow, but so are you under the effects of the magic.

The giantess tries to strike you and the fight begins. You only manage to leave a small wound on her arm before she grabs your body and crushes you in her hands. Just as she's about to break your neck, an imposing voice sounds in the room.
You tremble, with blood in your mouth. The giantess immediately stops.
"Don't kill him!" the voice orders.

A spell is cast, and your body is trapped inside a cage.
The wizard walks closer and looks down at you.
"I want to know everything. Who are you? Who sent you? And much more..."

You don't say a word, and he laughs "Sooner or later you will talk"
And then, he orders the giantess to put your cage on the basement.

You can barely sleep, and the cage is solid steel with no doors... a magic prison.

The next day, the wizard speaks to you again.
You try to explain who you are and what happened, but he only wants to know who sent you.
You resist the interrogation, but after a few days, you become so thirsty and hungry that, in exchange for a single glass of water, you reveal that someone in the city sent you.

He's not satisfied, and says that he will come tomorrow for more information, maybe you are not thirsty and hungry enough.

However, the water is mixed with a potion, and you don't notice it until it's too late.

Suddenly, you start to think that the wizard is your friend, and that you should help him.
The next day, you talk with him for a long time, giving him every detail and explaining everything you know. Satisfied, he banishes the cage and says that you are free.
"I don't want to kill you. You're just a foolish adventurer who was manipulated by another wizard."

But the potion affects you differently. You are not from this dimension, and magic affected your mind and body.
You don't want to leave and you start to serve them. The wizard starts to research about this strange effect and is fascinated with the magic working on your body.

The giantess is gentle and helps you all the time, and you start to feel something inside you... you find excuses to touch her skin, and to work close to her.

One day, you climb into her bed and kiss her large lips. It's a little difficult because of the difference in your sizes, but you manage to share a passionate kiss.

The wizard approves of your relationship and continues his research without paying any attention to you. He's not interested in love... he only cares about magic and knowledge.

Days later, you are sharing a bedroom with the giantess, and an intimate moment arrives. She taking off her clothes, and you stop her...

You are too embarrassed because of the size difference, after the potion or penis is smaller and she's too big, with your little thing you can't satisfy her...

She comforts you and says that love is more important than size, and that you can express your affection in many other ways... like your mouth and even with your ass.
When she takes off her clothes, you are surprised, instead of a vagina, she has a huge cock.

You don't care, you love her, and you use your arms and mouth to satisfy her sexual desires, the only issue is that when she cums, you are bathed in cum... the taste is sweet and it's hard to swallow, but you want to do it for her.

The cum from the giantess also affected your body, after a few days your body hair dissapeared and you breasts are bigger and your penis even smaller...
To avoid being ashamed, you start to use a special device to hide your penis.
A month later, you begin to use feminine clothes.

One day, she offers you a special healing potion that can regenerate your body... she explains that if you drink that, she will be able to penetrate you for the first time.

It's hard, and it take hours, but with the help of the potion, you survive and you don't feel to much pain, but your little hole is ruined forever...

After that... the piercings and you dye your hair, now you are a total whore, working during the day on the tower and having a highly active sexual life with your new girlfriend.
She loves your little breasts and, even with your chastity cage, you manage to cum when she penetrates you.

You have a long happy life, but you never returned to your world.

THE END
Bad Ending: "My girlfriend the giantess"
