Teach me to suck cock

I found a great big purple cock in my sisters room!

First I tried to put it in my pussy, but it wouldn't go in no matter how hard I tried!

I've been practicing and practicing sucking it like I've seen my sister sucking her boyfriend.

I like to watch! She makes all sorts of slurpy noises, but not as many noises as her boyfriend does. giggle

I want to learn to be a good cocksucker just like her, and I like doing it too! Especially when I put the little one I found in my pussy at the same time.

Can you teach a little girl how to be a good cocksucker?
