"Well, yes it's me! Cool, right?" - said Alice proudly smiling.
"No. I don't think so."
"Huh, but why?"
"Well, where to begin... First, you didn't warn me, second, you almost crushed me when you entered the room, third..."
"Okay, okay I get it! And also I made you very sturdy, so if somebody steps on you you'll be alright!"
"But why did you made me so small?"
"Well, I just wanted to play with you, but you refused!"
"Alice, I told you I had many important exams this week!"
"Well, now you're free, so let's play!"
"Okay, I'll play with you, but can you answer on my question?"
"Yep!"
"So can you grow me back?"
"Easily!" - said Alice very confidently, and there you saw your chance.
"I don't believe you!"
"What?"
"Prove it!"
"Hm! Fine." - she place you on the floor and stand up. - "Now stay here and don't move!"
Well, that was pretty easy. You decide to do as she told and just stand here. Alice start mumbling something and you saw her hands start glowing. Then you see as floor become further from your face, that's it - you're growing! Taller and taller, but then growth suddenly stops, now you were a few times bigger, you'd say you're a whole foot tall, but still far smaller than usually.
"Ha! Now you believe me?"
"Well yes, but I'm still too small!"
"If I grow you to your normal height you just run away!" - well looks like your plan didn't works, but at least there is some progress.
"So, what will we be playing? Hmm... Oh! I know!" - then Alice did most strange thing, though you've seen many strange things this morning. With a giggle she took off her panties and with a loud thud sat in front of you.
You couldn't believe your eyes, in front of you was pretty big cock with large balls, attached to your little sister. You weren't scaried, well it was pretty unexpected, but it was damn hot, as secretly it was your fetish.
"Uh... it's a dick..."
"Yes, it is. And you will play with it!"
"But where you get it?"
"Well, I just grow it!"
"Let me guess: magic?"
"Yep! And then mom and sis asked me to give them dicks too! I can give one to you if you want!"
"Erm, I already had cock..."
"Oh, I see..." - giggling Alice teased your hard on through your pajamas. - "Okay now strip down and let's play!"
You quickly toss your cloth and walked closer to your sister's dick, she spread her legs a bit for you. Just then you two heard a knock on her door.
"Alice! Are you sleeping?" - you hear mom's voice. - "I'm coming in!"
