When you lock a pair of sluts like Dixon Mason and Sasha in a cage together you have to expect that they will do what comes naturally eventually. If PD has given them a little bit of chemical enhancement to spur them on, it is just a coincidence. It takes some serious contorting for them to even get into position and before either one of them can really get off he has returned. He is going to make them do some work on the farm before he lets them finish enjoying each other. If they want any of the privileges he has to offer they are going to have to earn them.
