I will welcome you as a nurse in the treatment room for your final appointment. I'll reassure you; you don't need to be nervous; it will go very quickly now. You have to undress and lie down on the couch. I'll prepare a syringe with the shrinkage serum. I'll explain that I'll give you a handjob after the tip so that your heart beats faster and the serum spreads through your body more quickly. After the orgasm, the shrinking begins.
After the explanation, I administer the injection. I grab a slice of cheese and start wanking your cock. The handjob doesn't last long because you're so nervous that you jerk off after a few seconds and get smaller and smaller. I grab you between two slices of cheese and eat you up with relish.
