Pressure Gauge Christmas Challenge (x3 KOs)

Description: Can my slave take my squeeze for one minute at 20%? 40%? 60%? 80%? 100%?! if he does, i reward him for a minute in between the next squeeze pressure increase for some pleasure in a pain sandwich. if he doesn't, i punish him by giving him no break after he wakes up from ko only to himself being squeezed at an even higher pressure. there is no escaping in this challenge.
