The bottom electrode was beneath my taut brown scrotum, the other electrode on the mauve thick glans above. I'd never seen my erection so strong, seeping translucent white liquid.
At first, the current going through my penis and scrotum was mild, like touching your tongue to a battery, but then one of the women came forward and turned the dial to 3. My whole body, spread-eagled against the bark of the oak tree, arched back and convulsed. I played it up, just a little. Caroline turned the dial back to 0, and I slipped back against the tree, my chest heaving a bit.
"Wow," said a mousy woman wearing a thin cotton dress, coming in closer to peer at me.
"Caroline, this is amazing. What happens when you go to 4?"
"No," I said. "Please don't." But it came out as gargling because of the ball gag in my mouth.
"Nice," said one of the women, who came over and cupped her hand on my scrotum, tightening her grip until I winced.
"What can we make him do?" the mousy woman asked, putting her finger on the ball gag.
"Anything," said Cicely, the blonde woman who had first begun blackmailing me. She came in closer to me and moved her hand over my pectoral muscles and down my flat abdomen to close loosely on my erect penis, lowering her hand down behind my scrotum, and then, slowly and disturbingly, inserting a finger inside me. I grunted. She pushed it forward into my prostate, so drops of white fluid came out, and my penis grew even more distended as it responded automatically.
"See."
"What shall we have him do, then?" asked the mousy woman again.
"What do you have in mind, Vickie?" replied Cicely.
"Well first, I want to turn it to 4. Can I?"
"Sure."
I objected from behind the ball gag as Vickie moved over to the box. I could see her nipples pointing through her white cotton print dress as she put her hand on the dial and looked at me.
The others gathered around to watch, several of them holding up phones to record video of me. One stood very close to me, holding her phone so that my erection must have filled the screen. Then Cicely told them to stop. She came over, and moved the electrodes so that one was on either side of my scrotum.
"There you are," she said with a leer to her friends. "A different way to try it. Let's see how this works." I shook my head no, but couldn't speak.
Suddenly I could feel the current beginning to rise, first like a tingle, then I was shaking, every muscle taut. The sunlight was golden on my skin. I closed my eyes. I confess I was a little theatrical about it. When it stopped and I opened my eyes, I could see the tip of my penis was flecked white as if with frost from dried lacy and fresh seminal fluid. I hadn't come, just was seeping from the stimulation. One of them was still filming me.
They paused, talking for a moment among themselves.
"Hey handsome, time to set you free," one of them said as they undid the ropes and I stepped out of them.
"But stay naked, or you'll have more."
"Or worse," one of them said, and a couple laughed as they walked away to their cars, carrying the box and wires and ropes, all back in the pink duffel bag. Several of them waved and one blew me a kiss as they drove out the driveway.

No one came by for a couple of days, and again I had the strange feeling that it had all been a fantasy, that nothing had actually happened at all. It was on the third day, in the early morning, while I was having my morning coffee and watching the news, when I heard the tires on the driveway and the car's engine stop.
I took off my robe, went to the door, looked out, and saw a hand wave from the car window, beckoning me. Reluctantly, I opened the door and stepped out into the cool morning sunlight, the air chilly on my skin.
"Come on over, handsome," the mousy woman Vickie said. I could see her filming with her phone in her other hand. "I see you're not hardโthat means you get punished again. How are your balls from the other night?" She smiled, with small narrow teeth.
"Can I offer you coffee?" I asked.
"Sure." She looked just a little sheepish, and like she wanted to say she'd like something else, too, but didn't.
I didn't say anything. She opened the car door, got out, and slammed it shut.
"It's so amazing to be able to come over here and have a naked man at my disposal," she said with a wry smile. "I haven't had sex with my husband for so long I can't remember. Are you going to invite me in?"
"Seems like I don't have a choice."
"You really don't," she said with a laugh.
The morning air was delightful, and I could hear songbirds in the background. It was surreal.
"Look," she said. "I'm sorry about the other day. I think when we girls get together we kind of get a hive mind."
"Yeah," I replied. "I've heard when Indians captured settlers, it was the women that were the cruelest to the captives."
"That's true, really. We are cruel, and crueler in a group. And it was exciting," she said. "I've never felt anything like that sense of power over a man. What a rush to put my hand on that dial!"
It was strange, but although I should have been angry, I actually felt attracted to her. Unexpectedly, even to myself, I reached out and touched her hair and the side of her face. She looked just a bit conflicted for a moment.
"Should I be the only one naked, here?" I said with a wry smile.
"That's how it should be," she said. She wanted to keep the upper hand.
"I would like something, though" she said, looking at me.
"OK," I said. "Coffee?"
"Yes." I had the sense she wanted more.
We went to the back porch, where she looked around.
"I don't know if I dare."
"Dare?"
"To be naked too."
"Why not? There's no one around."
She looked around again at the rural countryside, and slowly unbuttoned the top of her dress. She looked around again, still tentative, then unbuttoned it enough to let it fall from her shoulders to the ground around her feet. She stepped out of it.
I was surprised, as she was actually quite attractive, with small brown nipples, and a brown bush below.
"It feels weird to be walking naked out here, doesn't it?" she said. I could tell she felt a little sympathy for me from earlier, and that she felt very awkward.
We leaned in toward each other, and lightly brushed our lips, then kissed more deeply. Our bodies came in closer, then touched. I could feel her bush.
"Let me get some coffee," I said, "before it gets cold."
"We wouldn't want it to get cold," she said, brushing her hand against my erection and smiling.
