"We've already got some interesting results," Mia said as she led him inside. "We'll go down to Cheon-Sa's obstetrics lab first, then my neuro lab next door after lunch. We have some time before the lunch delivery, maybe thirty minutes. We've had some subjects here all morning for observation, recording everything including hormone levels and high-res ultrasounds. Looks like two of them ovulated soon after arrival. Their bodies seem to know somehow to get ready for you. Still not sure how things like that are communicated. We're guessing something with the eyes, given what you discovered about eye contact already, so we're going to do some slow-motion video analysis. Anyway, we're pretty sure two of them ovulated. The actual egg is too small to see, but we can see evidence of its release on the ultrasound. One subject is a few days from her period and had already ovulated last week, but still was able to ovulate again this morning. That's not supposed to happen. Multiple eggs at the same time, yes. But days later, ovulating again? Never."

"So it's real," he said, instantly hearing how dumb that sounded. "I mean, you found something new happening to our bodies, it's not just in our heads, and not magic or a miracle."

She nodded. "My thoughts exactly. And that's not all. The post-ovulation muscular contractions of their fallopian tubes are far stronger and faster than usual. Those are what bring the egg to the uterus. Then they stop about an hour after ovulation instead of the thirty hours it normally takes for the egg to travel to the uterus."

"So that lets them go from ovulation to max fertility in an hour instead of thirty?"

"Yeah, sure looks that way. But again we can't see the actual egg, so it's guesswork. Cheon-Sa thought it was set to high-speed video playback when she first saw it. Said she's never seen a fallopian tube move like that."

"Wow," he said. This was what he wanted, wasn't it? Answers were starting to come. Real, scientific answers. Why wasn't it making him feel better? What was this feeling of rising dread? Just nerves, he told himself. Relax. Understanding all of this will help.

"Alright, here we are. Beyond one-way glass are two subjects who may or may not be the girls I've been talking about," she said as she led him into a darkened observation room. Cheon-Sa and Lanying were already there, greeting him with smiles. There was one-way glass on either side, with views of two different medical examination rooms, each with a beautiful college girl sitting on an examination table. Shihan and Ming-Yue, the doctoral students he had knocked up last night, were holding ultrasound devices to the new girls' sexy bare abdomens. They were wearing hospital gowns and underwear, with the gowns pulled up to their chests out of the way.

Cheon-Sa turned to Jim, asking, "Do you have a feeling about whether they're fertile, or will be soon?"

He took an extra few seconds to look them over as if trying to sense their fertility, but he was really just ogling them. He had no idea if they were fertile. But he was sure they were gorgeous, lovely sweet-faced tight young things with incredibly sexy bodies, recruited to his tastes with ever-increasing skill and selectiveness. Finally he shook his head.

"Alright, stand right here. Good. Now watch subject one," Cheon-Sa said, then pressed an intercom button. "Subject one, please read the first line from the eye chart."

The girl looked up, her eyes looking directly at Jim's, but she only saw the reflection of an eye chart from a monitor behind her. She read a series of letters out loud. God, what sexy lips, and what a sweet voice. "Still can't tell," he said.

"Ok, stand over here. A step right. Good. Watch subject two." She pressed another intercom button. "Subject two, read the first line on the eye chart please."

Same thing, perfectly lined up so that it was like she was looking into his eyes as she read, but he still had no feeling at all about whether she was fertile. "Still nothing."

"Ok, two-way eye contact seems to be needed, as we thought," Cheon-Sa said. "Shall we test that theory?" she asked, her eyes gleaming with excitement, her whole being loving this combination of her two greatest passions: scientific sleuthing and delivering new pussies to Jim. She pressed both intercom buttons together. "Phase two, helmets on, lights at max."

The two girls stood up, the exam rooms got a lot brighter, and the two doctoral students put helmets on the subjects with cameras attached, pointing backwards at their faces. Cheon-Sa put one on him too, double-checking the straps and tightening knobs to make sure the awkward heavy contraption wouldn't fall and would stay in position recording his face. She led him out and to the hallway outside one of the exam room doors. "I want to hear from you as soon as you feel something. Say 'mine' when you know she's yours, and say 'yes' or 'no' when you know whether she's fertile." Then she called out, "Roll cameras, max slow motion," reaching up to start his camera.

"Rolling," he heard from the intercom. Cheon-Sa opened the door and he saw subject one. Her eyes went wide and his whole being thrilled in response to that familiar gasp he could never get used to that meant she was his.

"Mine," he said instantly, confusing the poor girl even more as her brain struggled to process her sudden lust. Then a second later he added, "Yes."

Cheon-Sa led him to the other door. Subject one crept along behind, still very confused but just knowing she wanted to stay near him. Cheon-Sa opened the door and the other one was right in front of him. She too gasped and stared at him.

"Mine," he said again. And again, just a second or two later, "Yes."

They stopped the cameras. His new thralls were staring intently at him, breathing a little heavily. God, what a sight they were, fresh lovely faces full of lust, hot tight bodies squirming, wombs so ready for him.

"Did 'yes' mean right now, or sometime soon?" Cheon-Sa asked.

"Right now," he said. He gazed hungrily at them, soaking in and returning their lustful looks, fixing them in his gaze before continuing. "These two couldn't be any more fertile," he said. They gasped at his words, then they both nodded their agreement. They knew it too.

"Well then," Cheon-Sa said, "Would either of you like to volunteer for a study of impregnation?"

"What?" breathed subject one. "You can't be serious."

"Oh god," subject two gasped as Cheon-Sa nodded.

"We're studying human reproduction and especially Jim's reproduction. There is something special about him. About his babies."

She paused and the two staring girls both gulped at these words. Special babies. They both felt how true it was, deep down, so very deep down, all the way in their wombs. Jim could make the most unbelievably special babies. He could do it for them. In them. Right now. And he wanted to. They knew he really, really wanted to. His tented pants and his eyes made that so very crystal clear.

"Whatever is going on with Jim, it's new to science, and we want to understand it. If you agree to participate, you and your babies will be very well taken care of. We have some generous donors providing trust funds to support Jim's babies and their mothers, all the way through the babies' college education."

"Right here? Right now? With him? In front of you?" subject two asked, at first trying to sound incredulous, but utterly failing, the words coming out instead sounding breathlessly excited, hungry, each syllable even more drenched with lust than the last.

"Yes, we're hoping you'll let us watch," said Cheon-Sa. They gasped, looking shocked. "I mean that as a scientist of course. I mean I hope to be able to watch it happen using our instruments, like the ultrasound and those face cameras. It is a very important thing for science to understand better."

"Oh… Oh my god. I can't believe this, but I…" The girl he only knew as subject two trailed off, clearly about to say yes, but having a hard time getting the words out. She was squirming in place, panting.

Before she could finish, subject one blurted out, "I'll do it!"

Subject two looked like she was about to cry until Shihan leaned in and whispered something to her.

"He can? Like, right away? Two in a row?" she asked.

There was giggling and emphatic nodding all around.

They led Jim and subject one back to her exam room and closed the door. The two quickly shed their clothes. Their face cameras were turned back on. There was no way to kiss with those helmet-mounted contraptions sticking out in front of their faces, but he settled for holding both of her hands and gazing at her, then caressing her lovely but very nervous-looking face.

He stopped, feeling strange continuing without knowing her name, among other reasons. "I'm Jim," he said. "You don't have to tell me your name if you don't want to. But I'd hate to forget anything about this, and a name would help me remember you."

"I'm Zhao," she said, smiling sweetly. That really seemed to help. Lots of things still made it weird: the helmets, the medical setting, the others watching, but none of that mattered much anymore. No longer strangers, she finally relaxed, then gasped in pleasure as he began to caress his way down her now nude body, appreciating every inch of her and following his hunches about how to touch her just right. What a gorgeous slender feminine shape, tiny waist and wide hips, long shapely legs, large thigh gap, delicate, silky smooth everywhere, and that utterly angelic sweetheart face. Just amazing. An elite university was a pretty awesome recruiting pool, and they were fucking great at recruiting for him now.

He was spiraling in toward her pussy. She widened her stance to give him access. Even her pussy was beautiful, pink and perfect and glistening. He wanted to go down on her, but it wasn't possible with the helmet. He teased around it with light caresses, closer and closer until she was gasping and bucking out towards him. She was so wet when his fingers finally arrived, moaning with such urgent desire, and when he felt her tight entrance clenching on his fingertip, he couldn't wait either. So he didn't.

He stood up and laid her back onto the exam table, legs spread wide. He lined himself up, rubbing his tip along her slit and teasing her with it just a little before lodging it in her entrance. Oh my god, that felt good. Just that tiny hint of the embrace of her pussy right at the very tip of his shaft, so incredibly pleasurable already, the sight of it so sexy, her body all stretched out below him on the exam table, yet another sexy fertile hottie offering herself up to him, dying to get him inside her. He paused, savoring the anticipation and desire, soaking it in, while Cheon-Sa noticed he was bending his knees slightly and pressed a button on the side of the table to raise it a couple of inches.

He locked eyes with her again and began to slide into that gorgeous body, loving the reaction on her face, stunned, overwhelmed with the pleasure of it, eyes going unfocused at the delight of feeling him stretching her open, filling her, taking her. God, what a rush. It just never got old. That first moment of penetration. A new pussy spreading around him, embracing him. The pleasure of each new millimeter of it, the feeling of conquest, her incredibly sexy gasps and moans, her tight sexy body bucking and squirming, squeezing him, welcoming him, urging him on, needing him so badly deep inside where they both knew her fertile egg awaited.

Cheon-Sa turned the ultrasound screen so he couldn't see it. "Jim, stop and tell me when you get that feeling that you're at the most fertile spot."

He finally bottomed out, deep inside her, fully joined with her. He repositioned slightly, changing the angle, pressing around in there until he found that perfect spot that always gave him an extra jolt of pleasure. "There," he said, holding still.

"Yes, good. Hold on a sec," she said, clicking with the mouse at the ultrasound computer, taking measurements. "Another angle," she said to Shihan, who moved the ultrasound device around. More rapid mouse clicks. "Got it," Cheon-Sa said. "Ok Jim, you can move, then whenever you want to, try that again and tell me when you feel you're there."

He began to thrust, slowly, deeply, savoring the incredible sensations, gazing over her body, caressing her, playing with her lovely breasts, showing her with his eyes how gorgeous and special he thought she was, and soon they were both able to almost forget about the strangeness of the setting, the helmets, the ultrasound machine, the eyes and devices observing them. All of those distractions were nothing compared to the pleasure. They couldn't take away from this, make it less special. It was important to her and to him. The fact that it still felt so right and so perfect despite all those distractions was just another amazing thing about it.

He pushed deep on the next thrust, quickly finding that perfect spot that felt so right and holding there. "I'm there," he said.

More mouse clicks from the ultrasound computer. Shihan changed the angle again. More clicks. Then Cheon-Sa turned the screen to show him. "Bullseye, again. Exactly centered on the cervical opening. Impressive. That's all we need on that. Proceed."

He resumed his thrusting, again quickly forgetting about the medical setting, and was soon stroking powerfully into her body as she squirmed and bucked in pleasure, his fingers strumming her clit just right, her moans growing higher, both of them feeling their orgasms approaching as their heads were filled with thoughts of the perfect baby they were about to make.

"Wait, what's that?" Cheon-Sa asked. "There, behind the cervix. Zoom in. Hold still a second, please." He groaned but complied. He was so close, just barely holding on. Zhao was close too, clenching on him, giving a high-pitched whine of frustration when he stopped. The others were all gathered around the screen, looking close, so he couldn't see.

He was using all of his control to hold back his orgasm, but Zhao was already over the edge. She squirmed slightly on him as her orgasm broke with a sexy gasp and moan. He resumed strumming her clit as she rode it out, trying to keep still. God that was sexy, watching her come on him, feeling her orgasmic spasms, and it was also weirdly fun to see those spasms in the ultrasound. They had zoomed back out to wait for her orgasm since it was causing too much movement to see whatever they had wanted to zoom in on before.

He never knew the cervix could move so much. Neither did Mia. "Is her cervix pumping?" she asked.

"Yes, exactly," Cheon-Sa answered. "That's normal. The female orgasm makes the cervix pump semen into the uterus."

Oh god. That thought almost did it, almost broke his control. He could see his tip in the ultrasound, right there, right where her cervix was pumping, milking, sucking at him, so thirsty for his seed, working so hard trying to pull it inside where her egg awaited. But he held on somehow.

Finally, her orgasmic spasms subsided and they were able to zoom in on something just inside her cervix. A speck, a little blob floating in there was all he saw before they crowded in close around the monitor again, blocking his view and talking in hushed, intense voices as they zoomed in farther.

"Still waiting," he reminded them through gritted teeth.

"One second," Cheon-Sa responded, her mouse busily clicking. "Ok Jim, proceed but if possible try to minimize movement."

He groaned. He was close, but could he really come without moving much? He started doing very tiny, very gentle thrusts, just pulling out a few millimeters then pushing back in, holding tight on her hips to try to avoid moving her body. It was exquisite but slow, agonizingly slow, the pleasure building ever higher but not breaking. With every tiny thrust, his tip came back to that perfect spot, each time jolting him again with pleasure. He thought of her spasming cervix, so hungry for his seed, right there in front of his tip, and the beautiful baby she would make for him, and then with one slightly harder thrust he felt his orgasm begin to break. It happened in slow motion, his cock swelling, that agonizing moment of peak pleasure drawing out forever, his breath stopping, his whole body shuddering, then finally, finally he released, spurting deep inside her fertile body, pulsing out his seed, breathing again in gasps, seeing stars, the slow-motion waves of pleasure going on and on, but still managing to hold mostly still as his cock continued to spasm in her.

"Is it moving? Hold really still, you two. Oh my god, it's moving."

"Propulsion! How? Are there cilia? They'd be too small to see."

He still couldn't see the screen. They were all crowded in, talking excitedly.

"It's in the cloud of semen now."

"It's pulsing."

"Like it's breathing, or drinking."

The scientists' voices were giddy, breathless. They were beyond excited. They all seemed to be having like the science version of an orgasm.

A gasp from Zhao. He looked up at her and knew.

"Now," he said. "We just got that feeling she's pregnant." The joy was welling up, beautiful perfect bliss, his eyes locked with Zhao, sharing this unbelievably special moment, only slightly distracted by the contagious excitement of the scientists.

"Pulsing has stopped. It's retreating. Follow it, don't lose it. Hold still you two. Shihan, I'll take over, get the hysteroscope."

Shihan moved out of the way and Jim finally saw the screen. He gasped. In the center was a pear-shaped blob with braided strands coming out of the fat end. Grainy and...
