The next night

The next day, Harry made his way through his classes feeling much better than he had last week. Despite still being locked, he thought it would only take a week at this rate to get it back off. Then he could vanish the cage and get on with life. First, though, he had to get through classes. He would check the RoR that evening. Maybe his nipples would stop hurting by then too.

After making sure that the room was locked behind him, Harry quickly made his way to the armoire and directly towards the box of toys. Fishing the instructions out, he flicked to the page the last activation phrase was on, and sure enough, it had been replaced with a new one, as grey as the last had been. Looking below to the section labelled 'Pre-requirements', he stared at in disbelief.

Wear panties for at least eight hours directly before session two

Even if he put them on right this second, it would be morning before the eight hours would be up, and he would never get away with a session then. His best option, then, would be to take a pair with him tonight and wear them through classes tomorrow. He could keep a pair of boxers tucked away in his bag and swap to them after he was done. After thinking for a few second more, Harry decided that no matter how tired he was after each session, he would at leat check the requirements for the next. No point wasting a day like he had this time. Quickly finding the knickers he had chosen last time, thankfully fresh and clean, he stuffed them into his pocket and made his way back to his dorm to hide them away.
