Before anybody else could say anything, Wendy spoke up suddenly.
"Hey Tina, get away from him for a minute, I think I understood how that thing works! it looks reaaally simple!" I shuddered in fright at what she said from knowing that she was right. The remote was incredibly easy to use!
Looking at my grinning sister, I saw her sit on the bed while backing away. Then, Wendy came crawling on all four near the bedside. smiling excited, she pointed the remote at me while trying to hold still from the excitement. Instantly, I felt a surge of energy run through my body as a beam exited the remote and hit me. It only was a short burst however but I still shrank to half my size and became 6 inches tall in front of the two still bewildered girls. Both watched my small form in awe before bursting in a fit of giggling. Looking at each other, their expression carried their excitement to the other with a wordless exchange. I decided that I had enough.
Turning around, I wanted to put as much distance between me and the two girls. So I began to run toward the huge doorway still open after I came in minutes ago.
"Hey look Tina, he's escaping!" I heard Wendy's voice behind me say still laughing. And before I could even cover half the distance to the door, I felt booming footsteps shake the whole room and a giant form appeared in front of me, closing the door, and blocking my escape.
Looking up, past the tanned legs, the firm butt and large breasts, I could see my sister's face grinning down at me.
"Where do you think you're going bro? Wasn't this what you expected when you came in carrying that marvel with you?" She asked taunting and laughing.
I couldn't believe the size of her. With a single step, she could crush me under her foot and that would be the end of me. But as I watched my gigantic sister standing proudly in front of me, a sudden jolt took me by surprise as I once again saw everything around me growing bigger. Tina's form doubled in size, her legs becoming longer, her butt higher and her breasts larger! I must have been something like 3 inches tall!
"Wendy stop it!" I yelled turning around facing the other giantess playfully zapping my body with the remote while still laying on the bed. Laughing, she got up, and put her feet right in front of me. Looming over me, I felt intimidated by the walking wet dream that was Tina's friend. Long blond hair, shapely hourglass figure, with giant breasts and a tight sexy butt. Bending over, she poked me hard in the chest, making me fall on my back, while she laughed.
"What was that little guy, I couldn't hear you from up there."
Seeing her point the remote at me again, I whimpered.
"Please Wendy don't..." But it was too late, the beam hit me again and I shrank for the fourth time today.
The gigantic girls became even more gigantic as I shrank down to 1 inch still laying on my back from Wendy's shove. The girls were still laughing up above and continue to do so for a few seconds more before calming down and smiling down at me. Tina then crouched down and pinched my little body between her fingers before lifting me to their enormous grinning faces.
