Not very much at all.

The next day Maria is in her office, sitting in disappointment. They were a little over 24 hours into stage three and it had proved nothing, only serving to disprove potential theories.

John is enjoying his time with Joy, he is just a man and Joy is a beautiful blonde after all, but at no point does he or Joy go into the state he and Kira had been seen in repeatedly. The state where the genetic changes to their body happened, and where the disease is thought to mutate.

Joy and John both orgasm, but nothing happens, not what was expected.

Kira and Miguel are a testing failure as well. Miguel does his part well, and Kira has been willing to fuck him, but while willing has not been excited about it. Her body did not react to the lover Maria chose at all.

Kira had given Miguel a blowjob when they first started, as her dad had told her it was a part of the testing process, and had let Miguel cum in her mouth. And despite it not tasting good at all, she swallowed. Just to try and help her dad.

The trouble was that it seemed to give her an upset stomach, and she could not keep it down, she ended up throwing it up a bit later, as her body seemingly rejected it.

The second time Kira swallowed it wasn’t so hard on her body, but she obviously didn’t like it.

Miguel thoroughly enjoys his time with Kira, with him fucking the young and beautiful woman with all he had. Miguel also takes care to see to her needs, but it is one sided, as Kira’s body doesn’t appear to respond to Miguel cumming inside of her at all.

And he tried a lot, fucking her again and again. But it never worked as they had hoped.

Kira’s body does not seem to reject vaginal insemination, but there is no outward reaction to it. She seems to be somewhat bored, and a little sad to be doing it.

In truth she was a little sad. At one point she was lying on her chest and Miguel was behind her pounding away so hard she could hear their skin slapping, and she just looked at the observation windows.

Kira seems to feel ashamed at other people seeing her do this, as the team was monitoring what they do, and were watching, recording and taking notes. She had seems to have no shame at all when she did the same thing with her dad, that was different.

Maria then sent a different male nurse in, and asked that Kira give him a blowjob, for further testing. She hoped it would work for someone she had, but no luck. He loved it, but Kira again rejected the cum after swallowing it.

Maria needed a further test, was this her body rejecting Miguel, or her mind? They had enough data to know that Miguel would not do, but she wanted to test against it. She needed a control, she needed a sort of placebo to make sure it wasn’t mental.

She called for Joy, who came to her in just a robe, and instructed her to obtain a cup with his semen in it.

With John being comfortable with Joy it isn’t a problem. Joy disrobes and tittyfucks him, then brings him close to orgasm with her mouth, only to finish him in a cup. She then hands it out the door to an orderly who takes the cup, spending just a moment enjoying the view of Joy being naked.

Then Maria sends Miguel out of the room to clean up, and sends a nurse in with the cup. “This is another dose from Miguel, you two will be on a break for a little while, and this will help us to get some readings and data we need.”

Maria watches from the observation room, with a tablet in hand with the incoming data as Kira looks at the cup. Kira had tried swallowing cum from two different men other than her dad, and both had tasted terrible. She hated the idea, but she wanted to help her dad.

Kira holds her nose, and turns the cup up, deciding to swallow it quickly to avoid the taste, but as soon at it touches her tongue she halts.

Maria marvels as she sees Kira’s eyes open wide, and as they see her body temperature spike, and sees the young woman smile wide as she swallows, letting out a moan and struggling to balance herself as they see her orgasm.

Kira then hungrily cleans the cup with her tongue, and then her finger, which she cleans with her mouth. The young woman then lays back on the bed, and begins playing with her body, she doesn’t know it wasn’t Miguel. She still has the cup against her mouth trying to her more cum out of it.

Amazing, Maria thinks. She runs to Miguel, who is in the shower, “Get back in there right now!”

Miguel hurries back in, seeing Kira’s excites state and is hard almost immediately. Kira sees the man who she thought gave her the sample and has hunger in her eyes, welcoming him as he approaches her.

This time when she sucks Miguel’s cock it is different, she does it with even more effort, now even eye contact. He feels like she is trying to suck his balls out through his cock, fuck it is good.

Soon she lies back and presents herself to him with her legs wide, reaching out to him.

Miguel enters her body, and now Kira welcomes him inside of her, and as he pushes into her, she finally feels right about it. Tasting her fathers cum has really gotten her going.

Miguel pumps his cock inside of her and she quickly orgasms and he reels back from the heat, “Fuck, that is hot!” his dick quickly softening.

He backs away from the beautiful and orgasming young woman and exits the room to face a furious Maria.

“What the hell Miguel? Too much to ask for you to fuck a young, beautiful and horny woman? Get your ass back in there!” Maria shouts, she was about to answer to the CDC and the administration, she didn’t have time for this bullshit.

“Fuck it Maria, fire me if you want, I can get another job,” he replied defensively. “That shit burned Maria, it scalded my cock!”

Maria looked and saw what looked like a sunburn on Miguel’s rapidly driveling dick. “Well fuck,” Maria replied. “Go back to the hospital you were at, you are not needed here anymore.”

“After I get some ice for my dick Maria, a little burn treatment.” Mario replies harshly.

She went to the next option, an older orderly who close by, “You, get in there, we need someone else to fuck that young woman, go now!”

The orderly was in his fifties, and did not need to be told twice. He practically sprinted in, and luckily for him, Kira was a still coming down for the orgasm and did not reject him.

Even more luckily for him, her internal temperature had dropped, and it just felt hot as he pushed his cock into Kira, it didn’t burn him.

Maria watched in disgust, this was not a part of the plan, but she needed a man to cum in Kira a lot, really up until the government showed up and shut them down. He would have to do.

The orderly didn’t last long, but as before, Kira didn’t respond at all. That was three men from the lab other than John, and none of them succeeded.

This was a disaster, an almost complete disaster.

Maria went to check on the father and daughter she had brought in. They hadn’t been willing to do anything together, but Maria had chosen this man for very specific reasons.

His donor status was similar to Johns, his daughter was similar in age to Kira close to the day, and she was in a similar stage to where Kira was prior to all of this. Stage 1 anomaly, with sexual excitement when she was dosed.

And the father met another requirement, she had his browser history checked, and while he was careful to delete it often, that didn’t matter with the resources Maria has access to. He searched father daughter incest all the time, this guy was no better than that pervert John.

Maria arrived at the father and daughter’s room, hoping for a break.
