"All wired up?" Christina teased her friend, admiring her handiwork. Vanessa's naked chest rose and fell with her deep breaths. Her nipples were erect. Well, one nipple. The other one was hidden behind an electrode that was stuck smack in the middle of her breast. She wiggled her bare feet, conductive pads attached to the soles as well.
"I guess", the girl replied nervously, struggling in the stocks. "I just... I've never done this before. Are you sure it's safe?"
"Don't worry", Christina laughed as she connected the wires to a control box. "I've tried it on myself. You'll be fine. I'm going to use the lowest setting. I mean, if you're worried about it being _painful_, there's something we can do."
"What is it?" Vanessa asked. Christina rummaged around in her bag and produced... a massive red rubber ball gag.
"Open wide!" Christina smiled. "Don't want any neighbours calling the police." She forced the gag behind Vanessa's teeth, distorting her face. Christina buckled the straps behind her neck and, smirking, ran her fingers down her skin, across her pointed nipple, down...
"Mmph", Vanessa replied, her eyes following Christina as she walked around the table and connected the wires to a battery.
"We're ready". Christina put her hands on the control box. Her expression suddenly changed. Playful to sinister and... hateful? "Time to suffer, bitch." she grinned.
"Mpphah?" Vanessa's eyes widened. Christina picked up the control box, showing it to the girl. "Thought I'd forget what you did with Max, slut?" She turned the dial up, watching as Vanessa shook her head in panic, wiggling and trying to free herself.
"I haven't even turned it on. What are you worried about?" "Mphpmmh" the girl looked at Christina in panic, with pleading eyes.
"Too late." Christina put the box down. "You're going to pay for what you did, you dumb whore. Couldn't keep your fucking legs closed. Maybe I'll teach you to not fuck other girls' boyfriends ever again."
