The orgasm was the most explosive one of my life.
It literally knocked me off my feet and caused me to see spots before my eyes. I ended up panting on the floor with my panties around my knees.
I didn't remember pulling them down, but I must have shimmied out of them to give my hand more leverage to fuck my molten sex. My skirt was pulled up above my hips.
I was dazed. I held my right hand up in front of my face. It was coated to the wrist with my juices. My thighs were also shiny with secretions. I could clearly smell my arousal in the room.
Earlier that morning, I had been informed that my best friend and neighbor, Karen Higgins, had been living as the secret sex slave of a most unusual plumber named Kevin Wilson.
Then, as I watched with binoculars from my own house across the street, I had seen a brief demonstration of her submission.
Even this short taste was enough to push me over the edge to orgasm as I finger-fucked myself standing in the middle of my living room.
As long as I could remember, I had secretly harbored the dark desire to surrender myself to a truly dominant lover. Here was my perky neighbor living out my fantasies in real life.
After a few minutes, I rose up on my knees and picked up the binoculars. I trained the lenses on the bay window across the street. The shades were now drawn. The show was apparently over for today.
I sighed. I was surprised to find I was still horny. Absently, I ran my finger through my sodden slit. I closed my eyes and pictured my friend Karen naked on her knees...
I almost screamed when the phone rang. I looked at the caller ID. The call was coming from Karen's house. I had no choice but to answer.
"Hello?" I answered uneasily in to the handset.
"Hello, Mrs. Hansen, " a male voice chirped . "This is Wilson Plumbing calling to confirm that your service call today went well and that all questions were answered to your satisfaction."
I pulled the phone away from my head and looked at it dumbly before pressing it back to my ear.
"Just kidding, Amy," said the plumber in his normal voice. "How did you like my show with your friend? Quite a performance, don't you think?"
"Where's Karen, " I asked hoarsely.
"I sent her upstairs for a minute. She should be back in two shakes. In the interim, I do have time to take some questions."
"What have you done to her? Why is she doing this?" I asked.
"Well, that's two questions, actually," he answered breezily. "What have I done to her? I've made her my sex slave. Why is she doing this? Because she likes it. Like you do, Mrs. Hansen."
"But she's married. She has a family." I protested.
"What does that have to do with anything?" he replied. "As I said, I have no interest in meddling in the vanilla lives of my sows. The two worlds need never collide."
I was breathing heavily when I spoke. I had regained my composure. This was madness.
"I don't know what arrangement you have with Karen, Mr. Wilson, or how you manipulated her in to this situation, but I can promise you that I am not interested in anything of the kind. Please do not call this number again."
I was about to hang up when he said, "We can talk about that when you get over here, Amy."
"What? Are you crazy? I'm not going over there. " I shouted in to the phone. I stood up awkwardly, my panties still bunched around my knees.
"Don't worry, Mrs. Hansen, your friend will remain blindfolded. She'll never know you were here. She's used to having guests coming and going during our little sessions."
"Are you out of your fucking mind? Don't you understand I want nothing to do with you? There is no way I'm coming over there now or ever when you are in the house with her," I hissed.
When he spoke again, his tone was conversational: "Well, Amy, either you come over here right now or I will tell her that the jig is up and you already know about her arrangement with me. Frankly, I don't think she'll be too happy that you rubbed one out watching us through your fancy binoculars."
I said nothing. My face burned.
When he spoke again, his tone was almost conciliatory. "Listen, this is a very delicate time, Mrs. Hansen. Karen doesn't know that you know about our special relationship and I honestly think we should try to keep it that way for now. Think about your friendship," he said soothingly.
My hand tightened on the phone. "Listen, you psycho, I'm not..."
He cut me off. "Give me five minutes to get her blindfolded again. If you're not here in seven minutes, I'll put all the cards on the table. It's up to you, Amy. The front door is unlocked. Don't speak when you get here because she'll obviously recognize your voice. Bye, bye."
The phone went dead in my ear.
Shit.
I did some fast thinking. Okay, so my friend and neighbor Karen was having an affair with her mentally unhinged plumber. I was a grown up. I understood that this kind of thing happened. There was a little extra kink involved, but so what? They were both consenting adults.
I knew how these things worked. Eventually one or both of them would get bored and the entire adventure would sputter out of its own accord. I could easily see us all forgetting the whole thing and moving on with our lives.
But if Karen was made aware that I knew all the sordid details and had even secretly watched her submit, it would change the dynamic of our friendship forever. In my mind, watching her through the binoculars had been a harmless voyeuristic thrill, but from Karen's standpoint, my actions could very well be construed as a serious betrayal of trust.
Crap.
Calm down, I told myself. Nothing irreversible had happened yet. I was confident I could talk my way out of any further entanglements.
A plan began to form in my mind.
I would simply go over there, keep my mouth shut and string things along for a while. After all, he couldn't make me do anything against my will, could he? I would simply be a spectator. At the back of my mind, a small voice chimed in that I might actually enjoy it.
All I needed was a little breathing room, I rationalized. Then I could find a way to disconnect from this psychotic plumber and be done with the whole business. Karen would never even have to know that I was aware of her little dalliance.
I pulled up my panties and adjusted my skirt. I didn't have time to wash, so I would smell like pussy, but who cares? I would be amongst friends, right? I opened the door and jogged across the street to Karen's house.
The morning sun was warm on my face a I crossed the street. I felt as if I might be going a little crazy.
I arrived at Karen's house and silently opened the front door. I slipped in to the familiar foyer. My heart was beating mile a minute. I thought I heard someone talking in the living room.
Quiet as a church mouse, I crept past the kitchen and entered the large vaulted space where I had attended so many cocktail parties over the years.
Wilson was sitting in an upholstered arm chair, fully clothed, with his feet up, sipping a bottle of water.
He was using Karen as a footstool.
She was on all fours in front of the chair and he had his feet propped up in the middle of her back. He was still wearing his heavy work boots, which he crossed casually as I walked in to the room.
Wilson saw me and put his finger to his lips. He motioned me over to the side of his chair. I silently crept up, then stood watching the bizarre scene before me.
Karen was still naked. Her eyes were covered by a thick black leather blindfold. Her heavy breasts swayed beneath her. She had a look of profound serenity on her face.
Here was my best friend of over 15 years, suburban wife and mother, collared and naked on all fours, acting as a piece of furniture in her own home.
I looked her over more carefully. I have to admit she looked good. She always worked out just a little bit more than I did and the results showed. She had no body fat at all and curves in all the right places. Her arms and legs were taught with muscle. Her blond hair was pulled back in a pony tail. As my eyes took in her well-shaped ass, I noticed for the first time that she had a large black rubber plug protruding from her anus.
I had read about such devices in online stories and seen them in pictures, but this was the first butt plug I had ever seen in real life. I found it momentarily fascinating that my friend had willingly shoved this large object up her ass.
As if sensing my thoughts, Karen reached back and touched the plug lightly. "I think I'm getting used to it, sir. It doesn't hurt as much. I can't believe you finally got it in."
She sounded proud of herself.
Wilson picked up his feet lightly and sat up in his chair. He reached over and worked the plug in and out slightly, making sure it was seated properly. Karen groaned. I saw that it had a bulbous head that tapered down to wide base. From what I could see of it, the head looked absolutely huge.
"That's nice, cunt. Let's keep it in a while longer. I want that ass nice and ripe for later."
She wiggled her ass seductively, then actually purred.
Wilson slapped her smartly on the rump.
"Cunt, we have a guest with us today," said Wilson.
She stopped wiggling immediately and picked up her head as if to look around the room, despite her blindfold. I thought I saw a brief ripple of apprehension skitter across her face.
"Is there something, wrong, cunt? You've served many of my guests. Is there a problem today?"
There was a slight pause, then Karen seemed to collect herself. She looked straight ahead as she spoke.
"No, master. Forgive my rudeness. Thank you for allowing this sow to serve your friends. May this slave ask if the guest is a man or a woman, sir?"
"She is a woman, cunt."
Karen continued to look straight ahead as she said brightly, "Welcome, ma'am. I look forward to serving you if that is your wish."
"That will be up to her," said the plumber cryptically.
He continued. "Our guest is from a prominent family on the other side of town, cunt. She is considering acquiring a sow of her own. I invited her over to see how a fully trained slave comports herself. "
"Of course sir. I won't disappoint you." she said resolutely.
"I know you won't, cunt," he replied.
He paused and looked over at me as I stood beside his chair.
"Inspection!" he barked.
Without a word, Karen jumped quickly up off of all fours and stood facing us. Her hands were clasped behind her head. Her knees were wide apart. As I watched, she thrust her breasts and pelvis out in front of her as if to place them on conscious display. The plug remained firmly lodged in her ass.
Wilson stood and began circling Karen slowly, then he paused and motioned me over to her side.
I walked over and was soon standing only a foot away from my friend and neighbor.
I realized my pussy was tingling again. I was vaguely aware there was something wet was dripping down the inside of my left thigh.
I was breathing heavily and tried not to show it.
