His cast was going to make things difficult but...."Charlie, go and kneel at the end of the bed, will you." Charlie got out of bed, went round and knelt down as I had asked. I slid down until my legs were hanging over the end of the bed and opened my legs so that my pussy was right in front of his face."Have you ever seen one of. Jean came over to Paula and I laughing.

Henry did the exact same process, but Markus happened tolook the exact moment the cum was squirted.
