Dr. Witt: No tampering with the test subjects! This is the perfect time and we cannot wait until she is ovulating again.
Both men stand back and admire their handiwork. A rattling sounds from the back room as the humanoid senses the pheromones of the ovulating female. Hannah starts to rouse and immediately attempts to scream around the gag.
Paul: Good idea with the gag.
Dr. Witt: Now calm yourself Hannah or else you will get no explanation.
Hannah visibly attempts to calm herself, taking deep breaths.
Dr. Witt: Good. As I'm sure you realized Paul is still my assistant. We needed an appropriate female test subject for our breeding program. We have been attempting to cross breed humans and fruit fly hybrids. However, female flies and human men are incompatible. So we have decided to try the opposite. After mutating genes of normal fruit flies and then that of their ever growing offspring, in a few decades we have produced a humanoid fly-human crossbreed. Congratulations, you are our newest test subject!
At the mention of breeding program Hannah starts to fight again. She looks about wildly as she comes to the realization she is in trouble and the good doctor is actually a mad scientist.
Dr. Witt: Now stop that or I won't elaborate on our plan. That's better. After I revealed my research to Paul he was inspired to take part, however not as active a part as you will play. In the interview process you had to submit to special testing, including DNA. According to your results the "useless" extra DNA in your genetics makes you more susceptible to being crossbred. You have won the genetic lottery! Don't look so worried this is purely for the sake of scientific advancement. Looks at his watch. You're going to be a mother at this time tomorrow! The injection I gave you was part tranquilizer and part gene therapy to induce some of the extra genes to kick in and help increase fertility.
After giving his spiel, he instructs Paul to prep the humanoid. Paul comes back leading him into the lab. No prodding was necessary as natural instinct kicked in and the humanoid was drawn to the copious feast laid out before him like a fly to honey. He scented her pheromones and was drawn ever closer to the lab table. Looking down on Hannah spread out for the taking his proboscis was working double time, complexly sensing her readiness to mate. Hannah started to protest the best she could, thrashing about wildly and further exciting the humanoid. Hannah attempted to close her legs as he stepped between them. The stirrups held them open as far as they could go, giving him perfect access to breed her. Sensing her unwillingness, the fly instincts told him to lap at her genitalia with his proboscis.
For this being rape, it sure felt good to Hannah. Adrenaline had started pumping as she had sensed the danger she was in. And that monster fly thingy licking her cunt lips and stroking her clit was starting to make her pussy drip with honey of a different kind. It was a good thing she was gagged or she might betray herself with incessant moaning. The two geeky scientists in the corner taking notes made this act even more embarrassing. Of course being the thorough scientists they are they recorded and taped the whole mating.
Dr. Witt: Notice his use of the fruit fly behavior of using his proboscis to encourage her to mate.
The hybrid gently pushed his proboscis into her pussy, lapping at the sweet nectar of the highly fertile female. His human instincts pushed him farther up her luscious body to burrow into her huge tits, allowing his almost human looking cock to come into contact with her pussy. This caused Hannah to squirm almost uncomfortably. His cock felt huge and thick, and she hadn't ever had one. As his proboscis investigated her nipples, causing them to become rock hard, his cock probed at her pussy, starting to push in. Being a fly hybrid, he knew nothing about virginity. And the two men of science, having no common sense, hadn't realized they might need to accommodate for the tightness. Encountering a barrier, he shoved his dick into her with more force, unintentionally hurting her tender virgin pussy.
She started to cry a little from the pain, shaking from the adrenaline rush. Her hymen breaking, blood covered the hybrids cock, spreading onto the lab table. The foreign invasion caused Hannah some discomfort, but it started to feel a little better. He started thrusting harshly into her pussy, still teasing her nipples to stand erect. It was starting to feel very good. Very good indeed. Her pussy was now sopping wet with her own juices and blood. It was all too much for her. Her pussy started pulsing, squeezing the huge cock inside her repeatedly as she came hard. After what felt like forever, the hybrid came as well. His cock in her as close to her cervix as it could get, he started to unload his ridiculous amount of semen.
His semen was one continuous coil, entering Hannah's uterus and folding over itself as it started to bulge her belly out. After a few minutes of continuous insemination from a member of the species with the record size for sperm, she looked about 6 months pregnant. Oh my, Hannah thought to herself, at this rate I'm going to look like the queen of sea cows. Along with the bulging belly Hannah's tits became tender, accumulating milk and becoming heavier. They had started out as 38 DD's. Presently they were somewhere in the H range and continuing to grow. Her nipples had been small and pink. They were now the size of small dinner plates and the color of an overripe tomato. The skin on her tits and belly was so overstretched it was shiny and covered in stretch marks. Her tits were so full of milk begging to be released that her nipples stuck out at least 3 inches. Finally the impregnation completed, the humanoid stepped back and admired his mate.
Paul: That was even hotter than any insect porn I've ever seen. Too bad I couldn't have rubbed one of really quick.
Dr. Witt: For all of your brilliance you sure are a pervert! We will leave the soon-to-be parents to recover and will reconvene in the morning.
Paul removes the gag from Hannah and exits.
