You then followed Ms. Anderson to see what she was going to do now that she wouldn't be teaching any more classes for the rest of the day. She went to the principal's office where she said she would leave early to buy new clothes that fit her with her new dick, and the principal just looked at her exposed member and seeing you near the teacher, she understood that it was her will and how you could do whatever you wanted, you just accepted without complaining. You followed her out of the school building and toward the parking lot to get her car, but you didn't want her to leave just yet. You still wanted to have fun with her, so you figured what you wanted, thinking of Mrs Anderson growing to a giant size.
Ms. Anderson then stopped and started to grow. It didn't take long for her clothes to be destroyed and she kept growing, maintaining her body proportions until she reached 60 feet tall.
You climbed onto Ms. Anderson's foot and climbed up her leg, then onto her balls, where the surface of the skin was easier to grip. As you were the teacher did nothing to stop you from climbing her and her dick got hard as you climbed up her balls. You then walked over her hard manhood, which was now 35 feet, and used it as a springboard to jump higher and land on her left breast, from there climbing onto her shoulder and sitting there.
"You liked getting big, didn't you, you're already tough. What made you so horny? Did you get giant? Are you being fully exposed? Or did you like it so much when I climbed on you?" you said close to her ear
"No, I got a hard-on because that's your will. It was you who made me horny." Mrs Anderson said
"You are lying. I liked the development, but I never wanted you to get excited. You got hard on your own." you said
"Okay, since you want me to say it, I will. I have a fetish for giants, so much so that I have some model cities at home and I masturbate looking at them." Mrs Anderson said
"And with that you got horny for becoming a giantess. I want to see you come again but I don't want you to just jerk off. I won't be enough since your dick is now much bigger than I am, so how about..." you said and looked around, thus having an idea "OK , with your current size it should work. I'd like you to fuck up the school building. Due to your height you should be able to use the third floor hallway as a giant onahole."
Ms. Anderson didn't question it and went to the side of the school building, where she aimed her dick against the window at the end of the hall.
You then asked Ms. Anderson to wait a while, slipped off her shoulder, between her breasts and landed on the base of her cock. Then you walked over her hard member and lay on your stomach near the tip, holding on to her foreskin. You gave her the signal and she pushed her dick through the window.
Now you were lying on Ms. Anderson's dick in the third floor hallway of the school building, but it hadn't gone as you expected and there was still plenty of room left, so you wished your teacher would grow bigger until her dick was big enough to fit in there. From inside the building you can't see Ms. Anderson's size, but with her maintaining her body proportions and judging by how much her dick grew you would guess she must have be nearly 150 feet tall now.
This growth not only trapped you in the space between the cock and the ceiling, but the other people in the hallway were trapped against the walls and floor. As you didn't want anyone to get hurt so everyone was unharmed despite the pressure that would normally kill a person exerted on them and yourself.
Ms. Anderson started to move, using her 80-foot cock to fuck the school. You couldn't stay where you were and were flipped over, constantly shifting position on the tip of the cock, which was the size of a van. The entire building shook from the weight of the teacher's balls each time they hit the walls from the outside. Due to the tremors, those who were inside the school were having difficulties to even stand up, so they didn't dare to do anything.
Soon Ms. Anderson came, her cumshots quickly flooding the floor and down to the floors below, filling the school with her white seed, the excess escaping through the windows.
After Ms. Anderson's orgasm was over she pulled her cock out of the school building and with that you slipped off the member and fell to the floor in the hallway.
You then got up and looked around the size of the damage, had it to the side and it was possible to see several cracks in the structure of the building. There was now a huge hole where was the window through which the teacher stuck her cock before and looking out you saw how gigantic Mrs. Anderson had stayed. She sat on the floor making the floor tremble, breathlessly gasping as her cock became flaccid.
You still want to have more fun, you just thought a little and decided...
