Kim and Lisa sit together on their slave. Kim in the beginning on his face and the bigger (heavier) Lisa on his chest.
Kim is the girl who want more action, she ginds and bounces her ass on the face, the nose must go deep in the asscrack.
Then she ask Lisa to sit on her lap, so she has the double pressure with her ass to the poor face.
They change positions, kneel and make some buttdrops on him... Kim mostly on his face.
