As Much As Her Womb Can Hold

A white, liquid line traveled up the hose. Lois Lane felt queasy just looking at it. The normal ejaculation was a tablespoonful. She wasn't vastly familiar with artificial insemination, but she was pretty sure it involved no more than would fit in a syringe. What was headed for her overstretched cervix looked like...a lot more.

"Don't worry," the nurse patted the reporter's stomach, leaving a wet smear of lube and pussy juice. "The treatment makes your uterus elastic as well. The last woman managed to hold a full half a liter. We're hoping you can take a couple of liters."

"Liters," Lois repeated.

The white line in the hose disappeared into her pussy.

The reporter found herself gripping her ankles hard. It just seemed so unreal. Overkill, certainly. Most women only released one egg at a time. That much sperm would probably ensure conception, sure, but it was still immensely wasteful...

"Ugh," Lois said as she felt something inside of her. A weight. Heat. Pressure.

"It's going to go really slow at first," the nurse said, soothingly. "Want to see something?"

One hand still holding the nozzle inside the reporter's cervix, the other waggled a thin tube between the reporter's legs.

"As the cum fills you up, it's going to displace some air and liquid that's normally in your uterus," the woman said. "Normally, that would be really painful. So this little tube is going to let all that escape. The computer's monitoring the flow rate on the sperm in the tube, so when you're packed full, it'll stop automatically."

Lois could feel the pressure build inside of her. It was a bit like...needing to pee. But deeper inside. She thought about pregnant women, how they'd talk about the baby moving inside them. There had to be nerves in there, beneath the muscle.

How big is a uterus anyway? Lois wondered. In her head she imagined a red balloon, slowly pumped full...and fuller...until it sagged beneath its own weight, ready to explode. Liters of black sperm in her pussy.

There was no way she wasn't getting pregnant.

The reporter lifted her head up, to keep the blood from rushing to her brain. Her palms were sweaty, her gaping pussy dripping down the hose. The pressure was building steadily now, and Lois shifted her gait slightly. It was a weird position for it, all that semen being pumped inside, and she almost imagined she could feel her abdominal muscles being pushed out from the inside, the elastic womb swelling to make room... Lois swallowed, her body shaking as the pressure built and built, instinctual signals telling her that it was too much, that she needed to squeeze, to bear down, to void herself. She imagined the sperm filling up her fallopian tubes and impregnating all of her eggs at once...though she knew that should be impossible.

The urge to urinate grew inside of her. The swelling uterus was putting pressure on her bladder. She shifted on her heels, feeling like she was six years old again, desperately trying to hold it in. Lois looked up and swore that she could see a distinctive bulge in her lower abdomen as her womb, packed full, was swelling further and further.

"I have to pee," Lois said.

"Just a little more," the nurse said, calmly. "Once your womb is nice and packed full, we'll put the cervical cap in place, and then..."
