Marc 16: Chastity’s Challenge.

I feel a bit cucked as Chastity takes on three other guys while I watch.

I viewed the king-sized bed through the mirrored one-way window, standing with Dr. Lance Morris and Dr. Paul Fredricks. This is a science experiment, but it feels a lot like a peep show.

Still, Chastity had agreed to this enthusiastically.

She entered the room already stripped naked for action. The only marring on her flawless skin, was three wireless test pads attached to the back of her neck, her lower back, and between her breasts, over her heart.

“We should be able to monitor a full range of reactions here,” Lance said, pointing to multiple computer monitors on the desk before the window.

“This feels so wrong,” I said.

Paul shrugged. “You don’t have to watch, but Chastity wanted you to so you could write it up in one of your stories.”

I chuckled. “It’s not that I don’t want to watch, it’s just that…” I couldn’t put my feelings into words.

Paul nodded. “I get that.”

Three men entered the room beyond. They were all in their early twenties, fit, and similarly tagged with sensors on their naked bodies. They appeared hesitant, probably because they knew they were being observed and recorded.

Talk about performance anxiety.

But Chastity handled the situation…literally.

She approached the group, taking a hardening cock in each hand while going to her knees in front of the third.

There were some beeps from the computer, and bar graph levels begin to fluctuate up and down on one of the monitors.

“Feed it to me,” she said, gazing up at the man in front of her.

He took his cock in hand and guided it to her mouth.

As she sucked him in, she began to ride her fisted hands along the other two cocks, jacking them hard.

One of the men at her side reached out to fondle her breast.

“Mmm-hmm,” she rumbled around the shaft in her mouth.

“Oh, God,” the man she was sucking on said. He clenched his teeth and shut his eyes tight.

I chuckled. “That guy has no stamina at all. He’s ready to shoot already?”

Lance chuckled. “They’re all at the point in their therapy where every nerve ending is extremely sensitive. None of them should last long with someone like Chastity enhancing every sensation.”

The man pulled out of Chastity’s mouth with jism streaming from his cock. At the sight, the other two men came as well, coating Chastity with stream after stream of hot cum.

“Alright, guys, on the bed,” she said toweling off. There was no doubt who was in charge in there.

Lance smiled. “Chastity was my lab assistant before I had to move her and the other Psylons out of the complex.”

Gasping hard, all three men sat down on the edge of the bed.

Despite the fact that they had just ejaculated, two of the three were already hard again.

“Okay, a different kind of stamina, I guess,” I noted.

“That’s the Psylon’s feedback loop in play,” Paul said. “The hunger is only fed by their sex partner’s orgasm. Richard is bisexual, so he and Chastity received some hunger relief. The other two, being straight heterosexual males, did not, because Chastity didn’t climax.”

“It’s that complicated?” I asked.

Lance nodded. “The brain is a complex sex organ.”

“You.” Chastity pointed to one of the two that were still hard. “Fuck me. Make me come.” She tumbled onto the bed.

The man beamed a smile at her. “No problem.”

He crawled over to her and began sucking on her breast, as he palmed the other, rolling her nipple between his fingers.

“Oh, yes.” She arched her back.

As his hand slid lower, toward her crotch, Chastity took over tweaking her nipple. She was so wet her folds were glistening, and the man’s fingers slid easily into her.

“There,” Chastity gasped. “Right there. Now, use your mind to stimulate that area.”

His cock pulsed with need, but he held out, manipulating her with his fingers and, evidently, with his mind.

Chastity quivered in delight.

He moved in with his mouth, kissing his way down her torso to suck in and capture her clitoris.

“Argggh!” Chastity clenched her teeth as a climax rippled through her.

The man working between her thighs sighed and drew back, though his cock still remained at full mast.

On the computer screen, another bar on the graph dipped into the safe zone. I had to assume that the one still in the red belonged to the lone man sitting watching the action on the bed with his cock still erect.

I pointed at the screen. “Didn’t he get any relief from that?”

Lance shook his head. “It appears not. That’s part of what we’re testing today. Chastity’s climax doesn’t appear to have had any effect on him.” He spoke into a microphone. “Jerry, go!”

The man rose from the bed and hurried from the room.

“Where’s he going?” I asked.

“I’ve got two women primed and ready to administer to his needs in the next room. His hunger is peaking, and he needs some relief soon, and I don’t think Chastity has time to set up another climax for him.”

Primed and ready? That sounded interesting. There would be some questions to ask after the experiment.

In the room beyond, the other man was kneeling between Chastity’s thighs. He thrust his cock deep inside her.

Richard, the third man, stood to the side, observing. His cock had slowly risen once again to full staff. The corresponding bar on the computer monitor was also on the rise.

As the man between her legs began to piston hard, Chastity motioned Richard to her.

He crawled onto the bed, and she took his cock in hand.

“This should prove interesting,” Lance said. “Now that he’s involved in the act, he should receive relief from both of the others when they climax.”

Chastity came first, pulling Richard’s cock from her mouth to cry out in ecstasy.

Both men’s bars dropped on the computer display.

The man fucking Chastity came soon after, burying his cock balls-deep, and crying out. “Arrgh!”

Chastity’s and Richard’s bars both dropped.

Chastity pulled Richard’s cock back into her mouth in time to catch his load as he pumped her mouth full.

Her bar didn’t have much left on it, but that made it bottom out.

I noticed Jerry’s bar was also much lower, so those primed and ready ladies in the next room must have done their jobs.

As Lance started typing on the computer keyboard, going over the data that had been collected, Paul turned to me. “So, Marc, do you feel up to helping us with another experiment?”

I wasn’t about to say no.
