Now that you are nice and hard I want you to either use a ball stretcher or string and do exactly like that little slut there. I want your balls pulled night and tight.
To my trans slaves out there, you will take clothespins, attach to your balls, add string and then tie the string to a water bottle filled 1/4 of the way. This will stretch your balls nicely for me. I know you can do this, because I've done it to other dirty little sluts.
