I realized the only way to make sure the exercise worked was for Mitch to achieve a nice hard-on. I massaged his taint which seemed to start him up. I asked him to relax and to just simply enjoy the feeling. I dropped to my knees and took in all of his still juicy uncut cock. I sucked it so that his foreskin would move back and forth with every thrust. His dick was so good I got hard again and started to stroke my dick again. As soon as he saw that, I knew this kid was ready to bust it. I loved feeling his load spray and drip on me.  Guess it was a success!
