Rudimentary device for securing a lose penis. To create this device, a string is tied around preferably the foreskin or head of the penis if foreskin is not present. The other end of the string is attached to an anal toy of some sort. When the anal toy is inserted in the user's anus, the string will pull the dong between the legs and across the gooch, securing the penis in place.
