At the end of the work day, Laura took her pills. She had phoned ahead to the Mayim Clinic this time to check they were necessary, and Amy had responded that yes, they absolutely were, and that Laura would be in the chair again tonight.

The chair! Laura’s pussy was drooling at the thought even before the pill. She knew it was silly and slutty to think that way – it wasn’t the chair that had made her happy, it was just that she’d been on the aphrodisiac pills every time she’d be in it – but still she associated it with immense levels of sexual pleasure.

Laura made her way to the Mayim Clinic with her twat throbbing. She must have looked strange as she walked, surreptiously trying to rub her thighs together with each step to stimulate her cunt. She wanted so badly to just stop on the sidewalk as she walked and dig her fingers into her fuckhole, but she was getting better (she thought) at controlling her slutty pill-induced urges and anyway she knew the release of the chair was coming.

At the clinic, she was ushered into the changing room by Amy and didn’t even care that Royce watched her disrobe. His eyes roving over her naked, bare tits and her shaved cunt didn’t bother her. She just wanted to feel that vibrator inside her.

Amy escorted her into the room with the chair and bound her into the device. Laura’s arms were strapped to the chair, her legs to the stirrups, her waist held in place, and then Amy pushed the anal plug against the entrance to her ass, and slid the dildo into Laura’s wet, welcoming pussy. Laura sighed sluttily as it went in.

Amy wasn’t done yet, though. With Laura strapped in place, she approached Laura with a set of wires terminating in sharp-toothed alligator clamps.

“What are they for?” asked Laura nervously. She realised that in her haze of arousal she hadn’t even asked what the purpose of today’s work was. Amy had already said they didn’t need any more calibrations from her, so why was she in the chair?

Amy ignored Laura, but Laura soon got the answer to her question anyway. Amy clipped one wire to each of Laura’s nipples. The sharp teeth of the clamps bit into Laura’s titflesh, and she squealed in pain. She jerked back and forth, but there was no way to move her arms or escape the chair, and therefore no way to remove the hateful barbed clamps from her breasts.

“Ow! Amy, stop it!” Laura yelled, still wiggling.

“This is the next phase, Laura,” said Amy. “Conditioning. Don’t worry. You’ll probably even get to enjoy the clamps soon.” Amy still had wires in her hand, though, and it turned out these were for Laura’s labia. She reached between Laura’s legs and clamped one on each side of the dildo in Laura’s twat, the metal teeth biting painfully into Laura’s cuntflaps.

“Owwww….” whined Laura.

With no further explanation, Amy stepped back and started a video on the big screen. At the same time, the vibrator in Laura’s cunt began to hum and buzz, and Laura discovered Amy was right – the pain was unimportant next to the pleasure from the stimulation of her pussy.

The film was heterosexual sex, Laura saw to her disappointment. In fact, it seemed to be entirely blowjob porn. Each scene was more or less the same. It would show a kneeling, naked, big-titted woman. A naked man would step into the frame. The girl would open her mouth, and then the man would grab her by her hair, and push his cock into her mouth. The woman would suck on it for a while, and then the scene would change and repeat with a new slut and a new cock.

Laura was grateful that she at least had a good view of the sluts. She could see them kneeling, their tits presented prettily, and fantasise about kissing them or licking them. And when the women took the cock in their mouths, Laura could pretend it was her strap-on dildo. She sighed happily as the vibrator continued to pleasure her twat.

Then something different happened. A man was stepping up to put his cock in the mouth of a girl, but the girl turned away and closed her mouth, rejecting the cock. The tip of the penis bounced against her lips, blocked from entering.

Several things happened simultaneously. On screen, the man slapped the girl hard across the face. And at the same time, an agonising jolt of electric pain exploded in Laura’s vagina and breasts.

Laura shrieked and bucked in the chair, trying to get loose, but the straps were too tight. Her private areas were in overwhelming pain. She felt herself crying. She felt her bladder loosening and a trickle of piss running out of her pussy and dribblilng onto the floor.

And then, on screen, the slut, appropriately disciplined, finally opened her mouth and took the cock into it, and at the same time Laura’s pain stopped.

What had happened? Laura tried to think straight, but thinking through the aphrodisiac was like thinking through a blanket of fog. The girl had rejected the cock… and Laura had felt pain. What had Amy said? Conditioning. Laura was being conditioned to accept cocks in her mouth….

That was silly. Laura wasn’t going to turn straight just because they zapped her pussy. She was born a lesbian; that wasn’t a choice.

And anyway, her pussy felt so good again, being buzzed by the vibrator. And the girls on the screen had such very nice tits….

The next series of girls all accepted the cock into their mouths like good girls. Laura tensed up a bit on each, worried they were going to be disobedient and cause Laura to be shocked, but they all obeyed. Laura noticed during this period that there were variations in the intensity of her vibrator. The closer the cock came to the girl’s mouth, the harder it vibrated in her pussy. When the scene changed and the male was offscreen it basically stopped altogether. Sometimes the men would take a while to get around to putting their cock in the slut’s mouth, and Laura found herself mentally urging them on, wishing them to put their dick in her mouth as soon as possible.

During this series, Laura had her first orgasm, and it was wonderful. It felt even better than the ones she’d had on past occasions, and she wondered if it was becuase of the teasing from the variable speeds of the vibrator, or maybe even from the interruption she’d had from the electric shock.

She was still thinking about this when another slut on the screen refused to suck cock. The stupid blonde bitch shut her mouth and pulled her head away from the cock like it was disgusting. The man on screen promptly slapped her, and once again Laura felt electricity course through her tits and beaver. It was shorter this time – the girl was faster about getting the message and sucking on the dick – but afterwards Laura was surprised by the hate she felt for the bitch as she watched her suck the cock. The stupid little whore had made Laura get hurt. Why couldn’t she just suck the dick like all the other good sluts and make Laura’s pussy happy?

The pattern continued that night for hours – longer than Laura had ever been in the chair before. Girls paraded across the screen, most of them sucking on the dick they were given but some rejecting it. Every time a girl rejected the penis, Laura got a shock. Some girls took longer to come to their senses than others, and during the longer interludes Laura found herself begging the girls out loud to suck the dick. At least she thought it was out loud – it might have only been in her head. Between the pain and the pleasure the whole experience became surreal, like an erotic dream or a horrible nightmare. Laura lost track of how many times she orgasmed. At one stage she became aware her bladder was empty and realised it was because she’d pissed it all onto the floor over the course of successive electric shocks.

Finally it stopped as suddenly as it had started. The vibrator shut off and the screen went dark. Laura bucked her hips, trying to get another orgasm out of the device, but to no avail. Amy came over and began removing the device from Laura’s pussy.

“Amy please let me cum let me cum Amy please,” Laura mumbled.

“That’s not what you say, Laura,” Amy reminded her.

“Amy thank you for letting me cum. Thank you for putting a vibrator in me. Thank you for watching me cum like a slut,” Laura babbled. She remembered more. “Royce thank you for looking at my slutty pussy. Thank you for watching me fuck the vibrator. Thank you for looking at my big slutty tits.”

“What about the shocks we gave you, Laura? Aren’t you going to say thanks for them?”

“Thank you for hurting my pussy, Amy,” Laura said. Maybe if she got it all right Amy would let her cum again. “Thank you for shocking my titties.”

“Good girl, Laura,” said Amy. She was holding something in her hand. It was the vibrator that had just been in Laura’s cunt, stll dripping with Laura’s cunt juices. She moved it towards Laura’s face and pressed the tip against Laura’s lips. WIthout even thinking about it, Laura opened her lipsand took the dildo into her mouth. It tasted salty and cunty and Laura sucked on it enthusiastically. And as she did so, from out of nowhere she felt another orgasm wash over her. It washed through her body from her pussy, leaving her shaking and weak. She looked up at Amy with a look of pathetic gratitude in her eyes as she suckled on the plastic vibrator.

Laura realised Royce was standing between her legs. He was unfastening the clamps from her. A boy was touching her tits, was unfastening clamps from her labia. This was wrong, but Laura couldn’t move and anyway she was so confused. And it was good to have the clamps off. They had hurt so much.

When Royce was done his hands were moist with Laura’s sticky cunt slime. He reached forwards and wiped his hands clean on Laura’s cheek. Laura just let him, still suckling on the dildo. He looked at her and smiled, and then deliberately reached back down and stroked her cunt again, wiping his hand along it to coat his skin with as much of her fuck nectar and possible, and then deliberately reached out and squeezed her tits, smearing the juices all over her large funbags. Laura moaned and writhed. This was wrong. It felt good. It was slutty. There was nothing she could do about it. In the end she just let Royce do it, squeezing her tits and wiping cunt honey all over them.

When Royce had had his fun he stepped away and unbuckled her from the chair. Laura took the plastic dick out of her mouth and climbed unsteadily to her feet.

“Say thank you Laura,” said Amy again.

“Thank you for taking the clamps off, Royce. Thank you for letting me out of the chair.”

“And?” prompted Amy, looking meaningfully at Laura’s breasts. Laura was confused. She didn’t need to cum as badly now. Surely she shouldn’t thank Royce for that? He’d effectively been molesting her. But everyone was looking at her expectantly and she was so tired, and needed a drink of water.

“Thank you Royce for putting cunt juices on my tits.”

“Good girl,” said Amy again, and Laura beamed with pride. She had gotten it right.
