The last presentation before Isolde's was met with bated breath.
Everyone had heard about the new Cease-Fire Testicular collar, and it was quite exciting.
A professorish dude of about forty-two came up to the stage, accompanied by a young blonde girl with spiky rock star-ish hair, bright violet.
"I'm Nelson Giessbuhler" the professor guy said,
"And this is my assistant, Tinsel."
Tinsel was sexily clad in a tiny suede minidress, and her cleavage, in the hefty C range, were a sight to behold.
Tinsel gave a big shiny lipsticked smile.
Tinsel appeared, to Isolde to be in the alternative music scene just for the clothes, as the somewhat large, vacant hazel eyes looked as if they would only be attentive at a Katy Perry concert.
"My invention, the Cease-Fire Collar, is perfect for stopping a submissive's erection just before ejaculation, after extensive teasing." Nelson said this, with a tug at his ginger beard.
As the various kink distributors watched, Nelson removed his nerdy sweater-vest and unbuttoned his shirt, taking off the rest of his clothing fairly rapidly, enduring a giggle from Tinsel, and more than a few from the audience.
Finally, Nelson was standing naked on the stage, and Tinsel, who was holding a small box pulled out a small black loop with a plastic gadget attached to it.
"So, like usually Mister Giessbuhler is in his chastity device, but we took it off in the car?"
Tinsel smiled, waving the little loop around on one long magenta tipped nail.
"Hey, Connor, Biff which one of you has the handcuffs."
Two guys, also in punk rock regalia, one with a Mohawk, came up on the stage.
Isolde noticed the dramatic contrast between the naked little inventor with a small penis and a sweating pot-belly, and the muscular young men in their military boots and considerable tattoos.
"That's right, Con, just lock his hands behind his back. Mr. Giessbuhler gets squirrelly, you know?"
Nelson smiled, with more than a little blush, at the crowd.
"Well, I can take my share of teasing and punishment, Tinsel, I've been in the scene since before you were born, m'dear."
Suddenly the Mohawked chap slapped Nelson across the face, hard.
"She's Miss Tinsel to you, you sissy. Look at him, he got toenail polish on, it's disgusting."
Nelson looked at the floor shamefacedly.
Tinsel smiled apologetically at the audience.
"He forgets sometimes? Biff is a little hard on Mr. Giessbuhler."
Tinsel bent over and locked the little black loop around Nelson's ball sack, tightening it so the scrotum bulged a bit.
Conor took Nelson's ear and shook it.
"I know you want to show off your fuckin' invention, but you treat Tinsel with respect. Apologize to her right now."
Somewhat dazed, Nelson apologized.
His penis was getting somewhat larger and very swollen, enjoying Tinsel's locking on of the device.
"So I'm not real useta public speaking?" Tinsel said to the crowd with a brilliant, but clearly vacuous smile.
"But this is a real good invention. We hope you buy it. I didn't want to come?"
A horny old sales rep shouted out "We're glad you did, Tinsel!"
"Right. The boys told me that since I'm the one who gets Mr. Giessbuhler so worked up, it would be good if I showed you, as his tease-"
Suddenly Tinsel looked lost.
"Teasetrix my dear. You are my teasetrix."
Nelson said helpfully shrinking from somewhat threatening look by Conor.
"Yeah. You can call me Trixie."
Overcome by her own wit, Tinsel's glorious breasts shook in the suede frock, and the boys and Nelson smiled tolerantly.
Behind Isolde, Mistress Joely of Hampton, Maryland coughed. "No stopping this little moron."
No, Tinsel went on...
"Yeah, I help Mr. Giessbuhler in the lab, and also I um, teasetrix him a couple times a week."
She smiled.
"Now I'm gonna tease his Willy, and then you can see how the gizmo thing works. Normally Mr. Giessbuhler gets an orgasm every two weeks, but we wanted to show how intensely horny he can get, and how fast-"
"Too much information, my dear."
"What'd you say to my sister, you shit-head faggot?"
Biff unbuckled his belt, which had a death's head buckle.
"I was just advising that she proceed with the demonstration-"
Biff grabbed Nelson by his handcuffed elbow and used the belt, hitting Nelson's skinny buttocks thirty-two times before Conor and Tinsel were able to pull him off.
Nelson was now weeping bitterly. Staggering around, his rear looked as if it had been toasted on a fire.
Isolde wondered why the organizers had not stopped the display, but sadomasochists are a weird lot.
Remember, Isolde said to herself, You are a perv, too!
"Okay, okay, Mr. Giessbuhler."
Tinsel held the sobbing inventor's head, cradling it between her breasts as Biff, bored now, lit a Marlboro light.
Conor blew his nose the old fashioned way, shooting it through his left nostril onto the platform while having his thumb pressing on the right one.
"Remember, Nelson." Tinsel said, after giving Nelson a big, wet kiss.
"You're going to make a lot of money today, sellin' the shocker thing. You paid us five grand each to help with this, so you know you're going to make big bucks."
"I-I love you, Miss Tinsel."
"Whatever. Anyways, lets get this show on the road."
Tinsel reached down and began stroking Nelson' cock which had softened considerably after Biff's whipping.
But then it began to bulge. Fairly wide.
Isolde, who had dated men till her early twenties inwardly commented that this chap was probably a "shower" rather than a "grower."
Behind Isolde, the proprietors of "Mom N' Pop Submissive Shop" began chatting quietly.
"I'm going to use that, Lila, my dear. No matter how much it costs."
"Master Grant, the 'Cease-Fire' is for male slaves, sir."
"Yes, I was thinking of Thaddeus, our bookkeeper."
After about five minutes, Nelson's penis was straining, almost on the verge of breaking open the Cease-Fire Testicular thingie.
Clearly, Nelson was trying to get his manacled hands loose, and his legs were knocking together.
"Want to see my titties a little bit? The nips?"
To the audience Tinsel confided, "I don't let him see me naked or anything. It would be a violation of the employer-employee thing, I don't want to be a member of #MeToo. But this is a treat."
Conor snorted.
"That's right. This wimp's never seen her naked. He picked Tinsel up when he was teaching community college in Milwaukee, and we all moved in with him, and he's never seen her with nothin' on."
Nelson blushed, but was very distracted staring down Tinsel's cleavage.
"Okay, I kept him real, real chaste and teased him four times a day, so you can see not much would get him to go soft-"
"Right, usually I whip his dick with the ariel from my '77 Mustang to calm him down if we gotta lock him up so we can go to a show or something." Biff said merrily.
"But this is so much easier." Tinsel said, giggling.
"I mean Biff's my brother and Conor's my fiancΓ©, and we have a life to lead what with Conor's band and all-
And so this can calm Nelson down real fast. Are you ready to cum, Mr. Giessbuhler?"
Nelson's dick was streaming precum as Tinsel's nails rubbed it, and her soft forefingers played with the frenulum, the sensitive underside to his perspiring cock.
"Y-yes. Forget the demonstration, please just let me cum, It's been months and-"
"Okay, Conor, press the doozie."
Conor pulled out his cell phone.
"See, it's like a phone app. Perfect for the busy dominant homemaker to reel her guy in."
Conor touched a button.
Suddenly there was a silent quiver, and immediately, Nelson's penis went completely soft. No noise, though.
"You can do it at the opera or somethin." Tinsel giggled.
"I was bored when I went to the ballet the other night, but it was real dark, so I gave Mr. Giessbuhler a hand job, and then when it was time for intermission, I just shot off the Cease-Fire. It's awesome!"
Several more times Tinsel jacked Nelson to full bulbous, pulsating erection, and Conor zapped him back into tininess. At one point, Nelson burst into tears, but no one was worried about emotions.
"And if you have a phone and live in your sub's house, you can zap him whenever." Tinsel said vaguely.
Tinsel pressed the button and Nelson jumped, and then Conor pressed his phone, and Nelson jumped again.
"There's also a vibrator that will milk his cock without letting him cum, in case you're bored. Dr. Giessbuhler calls it "Electronic Edging."
Isolde had to admit she was somewhat impressed.
