You have been selected for my clinic's new medical trials. The instructions to participate were easy. You simply had to not masturbate for a week. I can tell you followed the instructions based on how horny you are! This trial is to test my new cum milking machine. I will mercilessly drain you of cum. For the next two hours, you will be strapped down to my medical table as you are milked again and again. I put my machine on you and you cum almost instantly! The suction feels so good on your cock. You are already aching for another orgasm. Not cumming all week has you feeling desperate to participate in my experiment. Now lay back, relax, and get ready to cum until there's nothing left!
