Riley and Chibi are both Littles, but Riley is Big Step-Sis and likes to torment Lil Step-Sis sometimes. She straps Chibi onto a door and begins to pinch and tease her before taking out her paddle and spanking Chibi's ass so hard that it ripples. When it's time to bully Chibi's insides, Riley pulls out a huge black dildo and slams it deep into Chibi's guts over and over. She can't stop thanking Riley every time she cums, over and over and over
