He gets too much attention for that

"You see, just with a little bit of cardio and a few simple exercises each day you'll be able to tone up your body and work up your stamina. My favorites are…" K-T was starting to zone out of what Lily was telling him.

It was already a very hot summer day and with all the machines running it was even hotter in the laundromat. He was sweating profusely which was kinda embarrassing while sitting naked right next to the girl he liked.

But there was something else distracting him from her workout tips. One part of his anatomy wasn't sharing this heat. The portal device had been set up right on a cold metallic surface and of course his balls were sitting on it, hanging loose from the edge of the device.

"... even if you don't do a lot of them, a few crunches will help you define those abs," she said, running her fingers on his stomach. He was rather slim but didn't have visible muscles there. He could feel his cock twitch at the touch of her fingers in a place that would have been so close to it if it wasn't for his sister's accursed device. "Girls like this a lot, you know."

K-T blinked a few times. Until very recently everything was rather innocuous and could just be considered as two friends going for ice-cream and talking about exercising. But it really felt like she was flirting with him.

"I'll… I'll try to start doing some, if my sister doesn't take too much of my time…ouch" he mumbled in response. Someone had yet again grabbed his dick and moved it a bit, except this time they had not sat it down correctly and a bit of the loose skin of his ball sack was pinched under the ring like device, pressed down by the weight of it and of his cock. It wasn't very painful yet but rather uncomfortable and he hoped it would not be left like that for too long, as he had no way to communicate with whoever had his junk right now.

"I'll talk to her. Just because she's your boss doesn't mean that she can stop you from getting in shape, better yet it could be useful to her in her experiments if you were a bit more fit. I'm sure she will understand." K-T was a bit anxious about her talking about it with his sister. Her first reaction would probably be to inject him with some sort of serum or zap him with a body altering ray of some kind, no doubt with the most embarrassing side effects for him. He knew that the work that she was doing had some world changing outcomes, but it always felt that more than half of what he was testing or helping with was specifically designed to or made in a way to embarrass or humiliate him.

Something was being poured on his cock, quickly followed by a pair of hands rubbing it. At some point some sort of sponge got involved and K-T understood that they were washing it after it had traveled inside a jar of his pee. Still it was hard to keep a straight face and listen to Lily while someone was basically jerking him off without her knowing.

He was pretty close to cumming when everything stopped and a spray of lukewarm water rinsed him off, he couldn’t finish but it wasn't cold enough to calm him down, leaving him even more on edge than he had been for all of the afternoon.

Then the poking started the now sadly recognizable round end of the sort of electrode stick his sister liked to poke him with during her tests (despite the fact that he was convinced that her handheld scanner was a lot more accurate since she always got to it after the poking). The simple contact of the rod was giving him some weird buzz, not really an electric shock, but a continuous eerie feeling.

From the regularity of the contacts and different feels while being handled, K-T was pretty sure than more than one person handling his missing genitals, hopefully only girls from what he could guess from their hands.

It continued for nearly twenty minutes. Thankfully he had been moved around and his ball sack was no longer pinched under the device. Still he felt that they were paying an awful lot of attention to his dick and balls for people supposed to be studying the portal device attached to them.

He did his best not to shout or flinch too hard every time he received electric jolts in his balls or on the now very sensitive tip of his hard cock.

Suddenly things worsened, what K-T had feared just happened. Someone entered the laundromat. A blonde lady probably in her forties, with huge tits and wearing a floral pattern short summer dress that looked one or two sizes too small for her came in carrying some empty bags, no doubt coming to retrieve her clothes from the machines.

"Heya, laundry day for you too?" she asked with a smirk. K-T had had the reflex to cover his crotch the second the door opened and she had not yet seen the weird device or missing bits between his legs. But there was absolutely no doubt that he was completely naked.

"No K-T just had a little accident, thankfully this place was nearby." while trying to defend him by implying he wasn't stupid enough to put all of his clothes in the laundry, what Lily said could let someone think he had simply peed himself in public.

The lady walked until she was just in front of them and suddenly bent down at the hips to retrieve something on the ground. Even before her remarks about it being laundry day her choice of clothing left little to the imagination, the very small dress was clearly not something she was wearing often and the lack of a bra underneath was showcased by her ample cleavage. Still K-T wasn't ready for what came next. Her lack of underwear didn't stop at a bra and bending down like this flashed her bare but and shaved pussy to Lily and him.

By a struck of fate it happened while he was yet again zapped in the balls and it pushed him too far and made him cum. Not a full orgasm since there wasn't any contact or stimulation on his dick, but he had probably sprayed a good part of the lab area in copious amounts of jizz (the researcher or lab assistants being possible collateral victims.).

Still in a daze, he tried to see what she was trying to pick up while confused by some very weird feelings after that last zap.
