You are going to be part of a medical trial, where we fill you up with cum, hundreds of guys will brutally fuck that hole of yours whilst you are strapped 24/7 to a gurney. The idea is that all this cum is going to make you even more virile and your own cum will be like super spunk. You will be hooked up to a milking machine so we can measure the quality of your cum over the duration of the trial. Now, face down, legs spread and take your medicine!
