I'm sick of you telling me what to do, just because you're older. Always bossing me around. Well that's about to change. I put something in your dr1nk this morning, and it's going to make you younger than me. It's already starting to work! I didn't think it would happen so quickly. Look at you! Your body is starting to get smaller, you're getting shorter. Your clothes look too big for you! Your body is getting smaller and smaller! Your clothes are falling off of you! Hehe look you're naked! You look like you're about 12 years old now.That means I'm 5 years older than you. How do you like being the younger sibling? You have a hard on! I thought you said that I was your annoying little sister but now your cock is hard for me! I want you to start jerking your little dick for me.I'm the one that it's control from now on. I did this to you little brother. You're going to have to do what I say. Now start stroking that dick for your little sister. Look how horny you are for me, I know what's going to drive you really crazy, my ass. Do you want to see your now older sister's ass? I want you to blow your little load for me. Hehe it's such a small cumshot. You're starting to get even younger! This stuff is so strong. I've regressed you so far back that now you're just an 1nfant. Now you're just a little baby. ou look hungry. Are you staring at my boobs? I guess I can breast feed you, I did get you into this mess. Hehe. Look at you, sucking on your little sister's nipples. You're such a cute baby. In this clip I give you the bratty treatment you deserve big brother while giggling and tormenting you.
