2 minute man -- chastity slave has two minutes to unlock and cum!

Once a year on his birthday, this hole-slave is permitted exactly two minutes to unlock its chastity belt and cum. The timer begins with the belt locked on, so if the slave is able to disassemble the belt quickly, he might have the opportunity to handle his dick for a few seconds before it is securely locked back up for another year. Will he be able to cum in time, or will he be immediately re-locked without any relief?
