Try to stop her before it's too late

Slowly but steadily, you take your thumb off the plunger while looking back at the doctor. "No, I can't do this... you see... I'm not even supposed to be here, it's..." you explain with slightly slurred words, only to be interrupted by the much older doctor. "Leap of faith, Mrs. Richards" she repeats and begins lowering your thumb back down. "No, no," you interrupt, only to feel your thumb touching the rippled surface of the plunger. "Stop," you add quickly, only to watch the vile contents of the syringe being depressed into the lower half and compressed for a brief moment before the beige fluid begins traveling into the attached tube downwards.

"Lady, please," you beg as you watch the goo traveling down the tube resting on your chest, going past your midsection and sliding within the thin plastic prison past your hips and then closing in towards your thighs.

The door to the room suddenly swings open and one of the nurses pops her head inside. "Oh I didn't know you are still in the middle of a procedure. Please, there's an angry patient and she-" the nurse explains only to be interrupted by the doctor who grumpily stood up and approached the nurse. "Yes it's fine, show me," she replies and the two of them leave the room. Saved by the bell! You lean slightly to the side and take a closer look at the extremely thin tube, spotting the gross liquid trapped within it. Jesus christ that was far too close. You exhale sharply and lean back to try and relax some after so much stress.

Relax... and relaxing you do. You wake up a few minutes later to a nurse entering the room and being surprised to see you seemingly abandoned. You stifle a yawn as she approaches you, your vision still a little blurry. "I believe the procedure is over, congratulations on the baby!" she explained as she began cleaning up the tray and putting various tools back into the intended drawers while you sleepily rub your eyes. Somehow, you managed to get out of that dreadful situation.

After a while of putting the sterile equipment away, she walked up to your side and took the heavy syringe out of your hand. Upon noticing that it was still full of the lifegiving slime, she once again showed a surprised expression. "Well that's odd," she mused as she flicked a finger against the plastic container, agitating the live sperm within and making the unpleasant fluid shift around.

Looking back down at you, she gives you a reassuring smile. "So many brave lil' soldiers still in there with nothing to do. Let's find these guys a new home, shall we?" the nurse offered with a kind smile, her thumb sliding up to the plunger and without further warning she began to press down, hard. "Wha? Wait, nonono!" you complain in your tired state as you look back down to the tube by your thighs. The entire mass of beige slime was rapidly beginning to move forward again and making a sharp turn as it disappears behind the blanket that still blocked the view at your genitals. You quickly try to shut your legs, but find your feet to be completely stuck in the stirrups.

There was a reassuring pause during which nothing happened, until suddenly and with high pressure, you could feel something slippery squirting against your belly from within. Unlike a man's ejaculation, this was a constant stream of goo as it was being delivered swiftly into the deepest parts of your womanhood. The mature woman's thumb applies more pressure while you lower your hands to your taut, flat belly.

Just like that and with peak efficiency, your brother's sperm had been safely transferred from the medical syringe into your nubile, healthy body. The entire process had taken maybe two or three seconds at most. "Is it... did you really...?" you ask her in confusion, still waiting for something more to occur, for your shock to be justified, but nothing happens. "What's... going on?" you ask her and she reassuringly pats your shoulder. "Don't worry if you can't feel anything unusual. The syringe was in your hand the whole time and reached your body temperature Mrs. Richards. Don't worry. All that sperm is now safely stored inside you," she explained while giving you a soft pat on your belly, just below the navel. "No, that... can't be," you say with a confused tone, while she rolled her chair back around to your crotch. Glancing back over to the syringe that now lay on the tray, you find it to be completely empty, even the attached tube was mostly clear once again.

The nurse's hand briefly snatches a tissue from underneath the exam table and inserts it into your still stretched womanhood. "I assure you it's in there. Your cervix is even drooling a little, as if it's really trying to spit that sperm sample back out, but," she explained as you start feeling her press the tissue against your delicate insides, "don't worry, it's all plugged up again. We'll give it twenty minutes or so to do its job, and then we are done here," she explained. "I recommend wearing a pad when going to sleep tonight, and for tomorrow. There is usually a good amount of leakage to be expected. However don't be alarmed, you're only leaking the empty seminal fluid. All the actual sperm will be safe and secure inside you for the coming days. Given your age and overall health, I am absolutely certain we won't have to repeat the procedure. I wish you a nice day," she said clinically before leaving the room without even remembering to close the door. To make matters worse, you're growing aware of a particularly pungent smell. After a quick look around, you realize that it's the vile scent of your brother's semen now that it's exposed to your receptive flesh. A few drops of it were still managing to leak out of your clamped cervix, creating a couple slippery trails along the inside of your 'virginal' womanhood.
