Some testing

Harry spent the afternoon wondering about the ray gun but with him not having a chance to return to the dormitories, there was little he could do besides checking on Hermione for any strange behaviours. She seemed to have noticed that her chest had gotten a bit bigger, especially when she managed to knock over some bottles during their potion class.

Finally, the evening arrived and the friends gathered once again in the great hall for dinner. After they were done, Harry excused himself and quickly headed up to the dorm rooms, where he pulled the ray gun out from under the bed. "How do you work?" he wondered and pulled his wand out, tipping it against the outside of the raygun. Nothing happened and he felt a bit silly. Then he had a little idea for the next day. "Diminuendo!" he said and tipped once again against the raygun, which started to shrink a bit.

While he put it into a pocket, he wondered if it still had the full effect or not.

The next day was Friday and while the class waited for spellcasting to start, most talks were about the upcoming weekend and everyone's plans. Halloween was also in the following week, giving them Monday and Tuesday off too. Harry himself wondered if this was a good time to give the bimbo ray some more testing.

Then the class started and he focused mostly on what Prof. Flitwick was saying. But towards the end, the urge to try the bimbo ray out more was overcoming him once again. He pulled it out of his pocket, carefully so nobody was seeing it. Then he casually looked around, seeing who was around him. Next to him obviously Hermione sat, still with her blond strain in her hair and her bigger chest. Ginny earlier had suggested that she sees Madame Pomfrey about it, but Hermione had told her that she didn't mind it at all.

In the row behind him sat Parvati and Lavender, their row a bit higher so Harry thought that he could reach behind him and zap them from below.
