I'm conducting an experiment into male sexual frustration and its effects on the size of a cock. My hapless volunteer has already suffered through months of chastity, but my aim is to prepare him for a full year of unrelenting denial, with his genitalia securely locked away in one of my many chastity devices. Naturally, I need to add many layers of rubber restriction on my bondage bed in the BDSM Laboratory before teasing and stroking him to the edge over and over again. What will this do to his shaft? Might it make it longer and harder, or will it start the process of shrinkage that is needed to get him into the device? Maybe I'll give him one "final cumming" before his long-term chastity torment begins?. Or maybe not?
