If you're a good slave for Me, your balls are the heaviest they've ever been. There's no more room for a single drop of the boiling semen that your crotch wants so badly to produce -- and wants even more badly to release. But there cannot be a release. You know it in your heart. If you cum any time you want, you're nothing more than a mindless monkey ... an ape with no brain, that I have absolutely NO use for. So buy this. Stroke nicely. Caress that swollen sack -- and KEEP IT FULL! Trust Me, you'll feel better that way, mmmmm.... ;)
