Confused, shifted your weight on the couch. Wasn't the infernal chastity device supposed to come off on its own? you lifted up the waistband of your sweatpants, and could just make out the tiny electronic timer showing six hours left to go.
Well, whatever. If it needs to be removed professionally, you weren't going to take the chance to have it on even longer. THREE months with an experimental chastity device was already over your limit, especially since you only agreed to two months at the start.
However when Lily from the clinic found out your "glandular responsiveness to arousal mechanics" was too low and she insisted on extending it to 3 months, you at first agreed, but now regretted that decision. Not that the actual time was the major factor, but that she upgraded the device so that the cage portion surrounding the head of your neglected cock was tortured with smooth ball bearings. It made it that every time you got aroused, the head of your cock would try to expand, causing the ball bearings to glide and shift around the head, making it feel like you were entering and pulling out of a soft, warm orifice.
