You flew down the stairs to the main floor and walked briskly toward the front door. As you passed the entrance to the living room you heard an all too familiar voice. “Hey, Little Bro!” You stopped dead in your tracks. Slowly you walked backward to discover where the voice had come from. Sure enough, Riley was sitting on the couch with a cup of tea in her hands and that infectious smile on her face. Your older sister Teresa sat right beside her with a cup of tea as well. “Hey, lazy bones. You’re off in a hurry after oversleeping this morning.” Teresa teased. “Uh yeah, I forgot that I have to meet my buddy, Steve.” You lied. You didn’t want to admit that your intent was to find Riley. A slight look of disappointment appeared on Riley’s face. Could she perchance have some feelings for you?

“Are you sure you can’t stay for a while with us? There is some leftover tea in the pot if you want.” Riley suggested. Since you didn’t actually have to meet up with Steve it was a no-brainer to stick around. The person you were looking for was sitting right in front of you. As you pretended to look at your watch, “I suppose I can stay for a little while.” You gave a wink as you headed to the kitchen to grab a mug for yourself. The girls whispered back and forth as you walked away but you could not make out anything of what they were saying. As you poured yourself some tea, your mind wandered back to the dream last night. The gigantic Riley staring at you with those piercing blue eyes through your bedroom window, the voice in the air that you didn’t recognize explaining that you now had the abilities to change the size of anyone. Was it true? Could you really have the capability to alter Riley’s size? You couldn’t wait anymore. It was time to try it all out.

You walked back into the living room with tea in your hand and sat in the chair across the coffee table from the girls. “How have you been? Haven’t seen you in a while. Keeping out of trouble?” Riley teased. “Yeah, no kidding.” You laughed. “Been keeping busy with work. That seems to keep me out of trouble… for the most part.” You responded. Riley laughed. Teresa began to regale Riley with the story of your family vacation that happened last month. Needless to say, there were plenty of awkward family moments during the trip to talk about for hours. As Teresa continued on, you examined the 5’1” Riley from head to toe. She sat quite ladylike on the couch. Riley wore a light blue blouse that showed off a hint of her cleavage. Her striped skirt covered the pale skin of her knees. Riley’s dainty bare feet barely touched the carpeted floor. She gave a brief glance over to you noticing that you were looking at her and smiled. You smiled back. She turned back to Teresa to politely pay attention to her. Riley looked up slightly to Teresa, who was 5’7”. Even Riley’s best friend made her look tiny! Now was the time to test out these supposed powers.

Not sure exactly how to utilize these powers, you pictured Riley taller than her current stature. Her head slightly rose and out of surprise, you stopped. Had she actually just grown? Or did she sit up straighter? No, she was already sitting straight. You swore she had to be half an inch taller! Neither of the girls seemed to notice. Teresa continued on about how terrible you were at giving directions on the highway and got lost for an hour. Once again you focused on making Riley taller. For a second time, her head ascended. This time you studied that change even closer. Riley’s legs stretched until her feet were planted firmly on the floor. Her toes slowly crawled toward you through the fabric of the carpet. Riley’s skirt was looking smaller on her as the hem receded to unveil her knees. Her ass appeared to be taking up more space on the cushion she sat on. You swore that her breasts were swelling up inside her blouse. A more defined line of cleavage was emerging. Your jaw dropped in awe of what was happening in front of you. Riley was almost as tall as your sister now!

“Hey did you hear me?” Teresa interrupted your focus. Riley’s growth stopped around 5’7” as you paid attention to your sister. “Hmm sorry I didn’t hear you. I was miles away.” You lied. “Sure you were, peeping tom.” Teresa dissed. You looked back to Riley and she blushed. You awkwardly smiled trying to pretend you weren’t staring. “Try being a little more subtle next time bro.” Teresa criticized. “But, didn’t you just see what happened?” You interjected. Both girls looked at you with confused looks. “What happened?” Riley asked timidly. “You just grew like half a foot!” You exclaimed. The girls looked at each other. Did they notice the change?
