It's an impossible command. At first, you think she wants you to duck away from her, to recede backwards. But the second she begins growing taller above you--her smile turning to a wide grin--you know your body is obeying Sara anyway.
"Oooooh my god, babe, it WORKED!" Sara says, practically shrieking, clapping her hands with giddy glee as your head dwindles past her bulging, huge breasts, down below her stomach. "Look at it! It's--it's really getting smaller!"
"Mmmmmm," Nicky says, stepping closer as you shrink beneath her breasts as well--just a bit smaller than Sara's, but proportionally, on her much smaller frame, they look bigger--especially now that each one is bigger than your dwindling head. "And you said you weren't sure about your potions. Look at it. Look at how scared it is."
Indeed, your eyes dart back and forth between Nicky and Sara, both of whom bend at the waist to look at you, as you tremble, feeling the boxes in the room begin to creep up on you and the carpet begin to snake up your foot. "I think I want to hear it talk," Sara says, smiling. "It's okay, you can say things."
"WHAT IS GOING ON?" you blurt out, stumbling backwards into a pile of boxes. "H-How are you doing this? What potion are you--how did you..." Too much. You spit out the easiest one. "I'M NOT AN IT!"
"Ummm, we said you are, though, so you are?" Nicky says with an eye-roll, and immediately you decide that it must be true. "You drank the potion, so that means you belong to us."
"B-Belong..." you spit out as you dwindle past the bottom of Sara's skirt, down her long legs, past her striped thigh-high stockings, trying not to stare at the looming bulge in her panties.
"It's simple, sweetie," Sara says, tucking her thumb under your chin--and around half your head--and making you look her in the eyes. "Nicky and I left that bottle for you to find. We expected you to just, you know, drink it. But hey, if you wanna come to us? Great! We don't have to go looking for you, and now, we have total omnipotent control over you."
"T-Total..." you repeat, grabbing her finger with your tiny hands, shaking. "O-omnipotent..."
"Whatever we say, you do," Nicky adds. She sits down on the floor right in front of you, putting her hand on your head as you shrink. "Even stuff that's, you know... impossible. We can change you into whatever we want, make you obey us..."
"Make you a teeny itty-bitty toy..." Sara giggles.
"We really wanted to do that one," Nicky says.
"And so we did!" Sara says, jumping up and hopping up and down, clapping her hands together with giddy glee. "So we're, you know, gods to you!
"Super gay gods," Nicky says.
"The gayest!" Sara squeals.
You can barely stand up as you brace yourself against the boxes, trying to breathe. You can't argue with them--not just because it's literally impossible, but because the logic perfectly tracks. Somehow, the two girls from down the street have gained total control over you, and you've dwindled down to the size of a toy at their feet--about three inches tall.
Your eyes fixate on Sara, who is massive now, hands on her hips, her high-top shoes looming just over your head. Leaning down so she can see you over her gigantic breasts, she smiles.
