The next day

The next morning, Harry was up early. He knew that he had to shower and get dressed before any of the other boys got up and saw either the cage or the panties he would be wearing that day. One quick wash later, and Harry paused, looking at the knickers in his hand. Was he really going to do this? Knowing that he had to make a choice before anyone woke up, he slowly stepped into them and slid them up his legs, his skin tingling with pleasure. As Harry finally tugged them into place, his legs quivered and his cock strained in his cage, trying and failing to harden.

Feeling slightly out of breath, he jolted as he heard the noises of someone waking up, scrambling into the rest of his clothes. The whole day, Harry found his attention wandering to thoughts about his current underwear. They were so soft and silky, and fit much better than the boxers that he had been wearing until now. As his thoughts wandered, the compulsion layered on the panties started interfering. 'They were so comfy, and they felt nice on his skin. They fit better, and make his ass look great.'

Decision firming in his head, Harry decided to keep wearing the panties, and to get more from the armoire. He would even get rid of most of his old, worn out boxers to save room. True to his new decision, that evening Harry went to his dorm and emptied all but a few of his boxers, leaving the new ones he would use when he needed to. The rest went into his expanded pouch, before he ducked under his invisibility cloak, making his way to the armoire.

Once there, Harry dumped out the pouch, his boxers making a small pile on the floor. A quick spell shredded the fabric past what a reparo could fix. Another one banished the remains under one of the rows of clothing, never to be seen again. Turning, he pulled open several drawers of underwear, pulling them out and making a pile on the floor behind himself. Briefs, thongs, tangas, at least one of every style joined the pile, in several types of fabric. Feeling elated, Harry started stuffing handfuls of them into his pouch to be put in his drawer later.

Stripping down, leaving him standing in just a pair of panties, he put his clothes into the pouch as well. With a giddy breath, Harry checked the booklet for the right phrase, and with a pulse of magic, started his second session.
