Sister Teases His Small Dick In The Bathroom Then Craves More

She barges in while he is about to shower and demands the tub for herself then yanks his towel off to mock how tiny he looks. Her playful insults quickly turn into curious touches that make him grow rock hard in her hand. Soon she is bent over the sink begging him to fuck her deep and discovering she cannot get enough of her stepbro after all. They both finish shaking and agree to keep this new game between them.
