Mistress Kawaii has a surprise for her slave. Today, she really wants to test his limits. She wants to do this because she wants her slave to truly submit. Kawaii bounces high and hard onto the slave’s face with her full weight. The slave really struggles to take it, even at the start, and Kawaii smiles. She slaps the slave’s face over and over with her curvaceous ass. Kawaii decides to bounce hard on the slave’s abdomen, right over most of his vital organs. She nearly cracks one of his ribs! The slave tried to call ‘red’ and end the scene at this point, but we wouldn’t let him. We insisted he take a few more. The slave was completely terrified, but we had him in a bind. Kawaii does more full-weight butt drops onto his ribs, knocking the wind out of him each time. Then, she lays on top of him, pinning him down beneath her completely. Kawaii gives him one final intense butt drop, then strikes a victory pose.
