A quick test on Parvati

As their class was coming to an end, Harry decided to give something a try, which he had wondered about for a bit. He put the raygun into his hand and leans back, casually aiming upwards. Then he quickly pulled the trigger and blasted Parvati's pussy just for a moment. A gasp could be heard from her but Harry quickly pulled his hand back and put the raygun away again.

"Everything okay?" Lavender asked her friend, who had dug her fingers into the table.

"I ... I ... yeah, just ... I am okay," Parvati said but it didn't felt very convincing. Before Lavender could ask more, the lesson ended and Parvati was one of the first to rush out of the classroom.

"What wrong with Parvati?" Ron asked as Hermione, Harry and he got up themselves.

"No idea," Hermione responded. "Maybe she really urgently needed to hit the bathroom.

Ron shrugged and they left the room. Harry, who had hoped that something like this would happen, had packed his invisibility cloak and told his friends they should go ahead, as he forgot something. As everyone was out of sight, he pulled the cloak over his head and headed for the nearby girls' restroom. He could hear some very suspicious sounds from the last stall. As he expected, he found Parvati's bag in a corner in front of it. The door was only partly closed and in the right position, he got a good view inside. Parvati sat there, fucking herself with her wand while biting her lips to not make too many noises.

Harry took a mental note that the ray could be used focused too. Parvati hadn't changed physically, but she clearly couldn't stop masturbating. Just as he stood there, the young woman had an orgasm and managed to slow down a bit although still moving her wand in and out a bit. Harry stood there, trying to decide what next. Should he blast her more or leave it for now and see what other opportunities for testing would come up?
