With a Vibrator

"S-sure." Said someone on the front row, a red-headed guy in a football shirt of some sort. "Just what do you have in mind, though?"

"Good question!" David said, gesturing towards him with a grin, his face a mask of anticipation. "Very good question. Now, let me see...Ah yes! I have a good idea!"

He reached into the bag that he had been given by Anya, Lisa watched with trepidation, wondering just what he would bring out for her now. Her body felt cold, she was shivering, all of her hair was standing on end as David palmed through the contents of the bag. After a minute or two, he seemed to find what he was looking for, he withdrew, looking to her with a grin that made her spine tingle. Almost against her own better instinct, Lisa peered at the object in his hands, trying to find out what it could be. It seemed to be a thick plastic rod of some sort, coloured black, and with a space to insert batteries clearly already used and full. She felt her mouth turn dry as she realised what it had to be.

"Here, ****." He tossed it to her suddenly, making her jump and reach for it, snatching it out of the air only barely. The sudden motion meant that she bared her body, making several of the boys present smirk or cackle. The device felt rubbery in her hands, with a layer of metal below that. She was sure now that it was a vibrator of some sort, but could find no way to turn it on or off.

"Put it on." David said. She blanched.

"E-excuse me, M-master?"

"I said put it on." He said. "Or in, as the case may be. What, is it too big for you?"

Lisa felt her hands trembling as she looked down at the device. the fact of the matter was that yes, it was too big for her currently. Though, she usually got off on this sort of thing, her current situation was far too horrifying for her to be enjoying it. As a result, she wasn't the least in the mood, and her pussy was not exactly in a state to just have a length of rubber shoved into it.

"Well?" David said. "What's the problem?"

"Um..." Lisa stuttered, trying to figure out how to phrase her request in the least humiliating way. "Uh, y-you may not know but we girls...we uh...we need to get ready for something like this... that is to say..." Her cheeks were flushed red now, and her eyes were darting across the room, trying to find somewhere, anywhere to look but David. "We can't really go in dry..."

"Is that so?" David said, stepping closer to her. "Is that so?"

Lisa resisted the urge to shield her naked body as her master stopped inches from her. One of his hands moved out to grip her collar, twisting it back so that her back arched, and she loosed a growl of shock and displeasure. At the same time, she felt his other hand probing her mound. Her sensitive skin flared with life as his fingers sweep over the soft skin of her Mons Pubis, and then down towards her labia. David was rough, fumbling, his skin rubbing against hers with excitement and naked lust. She felt her legs twist and writhe as one of his fingers entered her, then another. The **** intrusion made her grimace, especially now it was happening in front of everyone.

"Ah!" She cried. "P-please!"

"Not what you're supposed to call me." David said, ignoring her cries as he probed deeper, his fingers roughly filling her up in an unpleasant way. She twisted her head back and forth, fighting against the feeling of his probing. In fact, he seemed to be going harder on purpose. Making her gasp and whine with each entry, there was no subtle touch to this, no gentle pressure. It was rough, deep, and uncomfortable, making her try to twist her body away only to be anchored by the damn collar.

"Ah!" She growled. "M-master, please!"

"Better." David said, withdrawing from her for a moment. Lisa sighed, sagging as she feeling was removed. He held his fingers up to his eyes for a moment, and then nodded.

"You're right, ****. You're as dry as a log. Well, we can't have that, can we?"

He held up his phone, a clock app already open. As she watched, he marked out five minutes, and then turned to her.

"You have until this alarm to make yourself as wet as possible. However, you're not allowed to use your hands."

Lisa felt the first pings of panic.

"B-but master, then how am I supposed to...?"

"I am sure someone in the audience will help."

Bastard. Absolute bastard. She tried to glare at him, tried to muster her rage and anger, and throw it at him so he knew how much she despised him right then. He just smirked on through it, then hit the start button on the watch.

"Time's running out, ****."
