Maria makes sure little time is wasted.

It doesn’t take long for you to be called out of the room, and you are lead to a new room by the cute young intern Joy, and you enjoy watching her ass sway in her too small scrubs as she walks. Maria chose well, this is a very pretty young woman.

And her scrubs are a couple of sizes too small, it looks really good.

“So, Joy right?” You ask as you get into another room, with Joy closing the door behind you.

“Yep,” she said with a perky smile, you imagine that this young beauty bounces around everywhere she goes. The envy of most women who see her. Joy knows it, she hit the genetic lottery.

“Good to finally talk to you, this was a tough program to get into, I was close until I caught Sperma Proclivitas,” she replies. “But Maria usually won’t take anyone who tests positive in the building, she is terrified of this disease.”

Beautiful, blond hair and blue eyes, a nicely symmetrical face, and a cute ass and nice tits that were well accented by a tight little set of scrubs. A lab coat would be a crime on this young woman.

Joy didn’t waste any time, as you we speaking she started to take off her clothing, and it turned out the scrubs didn’t accent a nice fit body, they were concealing an amazing body.

Taller than Kira, with smaller tits, but a body honed in the gym. Her abdominal muscles were well defined, she had nice shoulders, nice calves, and when she pulls off her top you see she is actually hiding a rather nice set of fake tits.

You know how she pays for medical school, you see it often. She might as well have Pole Dancer’s Proclivitas, this young woman made her living without her clothing on. But you knew she would be flexible, and you knew the pole on the stage would not be the only one she had practice on.

This would be fun.

When Joy is naked you really appreciate the view. Nice tan, she got her ass from the gym, she was really well put together.

You take off your shirt, and it looks like she enjoys the view, and then drop your pajama pants. “Are you dating?” You ask her, interested in getting to know her just a little bit.

“No, you know how it is doc, way too many hours at study for anything more than work and extra credit time with a professor,” she replies. “And with all the hours in the hospital and in the club, there is no time to date. You know what I mean, I’m sure it is why you are still single, being both fuckable and rich.”

“Extra credit time with a professor? What is that?” You ask.

She smiles and hesitates, you realize what she means, “you know what it is. You have never don’t it probably, but when you look like me it is a part of the deal.” Joy paused and then continued, “my grades are good but the old man made it clear what it took to make it into a good program. Extra credit, and he made it clear how I earn it.”

“Once a week I drop by his house, and he gets to fuck me,” she continued, worrying that she risked ruining this. “A condom is worn, no oral, no kissing, it is what it is.”

She seemed to be honest there, it always felt good to be around honest people. “So what would you like to do Joy? Sexually I mean? I think we have a day or two.” You ask, “and what stage are you? You seem lucid, early stage 1? Stage 1a?”

“1b actually, I am at risk for stage 2, which would end my medical career, at least until a cure is found. So I have an interest in helping here, I need this to work. I need for it to work quickly.”

She sits down next to you, and you admire her body as she begins to stroke your cock.

“And I have been ok with this thing so far, I love sex and I work in a strip club. I have access to a lot of cock,” she replied. “I enjoy pretty much anything, I wouldn’t mind a shot at your daughter if I were honest.”

That didn’t feel honest at all, she looked like a stripper, but you doubted it now. This was a character Maria cooked up, nice try actually, playing to his stripper fantasy.

“Do you present as an anomaly Joy? Have you experienced more than the normal symptoms?” You ask.

“Yeah, from the start,” she said, before smiling at you sweetly. “I have a lot of sex drive anyway, and this made me a bit crazy for it. It has made it easier to get my treatments.”

“Even here in your lab,” she says softly, looking closely at your cock, leaning in and putting a kiss on the tip, then smelling it and nuzzling it. This was real, she was dealing it. “I have been able to get enough to get by while we waited for my time with you. At least I hoped this would work out for me.”

She then puts your cock in her mouth and begins to suck it without any hesitation. Ok, that was really genuine, she is feeling it and she has sucked cock before. She is doing it like a pro.

You know that Maria chose Joy for fitting a fetish you have long held, the blonde stripper who falls for you. Her having a similar stage of Sperma Proclivitas to your daughter also increases the possibility of a positive result.

You feel Joy pushing your hard dick deep into her mouth, it might even be in her throat. The sounds she makes change as she keeps working her way down, before finally you think she has all of it, in her throat. That is pretty nice.

You want more, you want to take a little bit of frustration you have with this process and with Maria our on this beautiful young woman’s beautiful body, but science must come first.

You reach down and gently squeeze one of Joys big tanned breasts, and she means in pleasure. She seems to indeed be at stage 1b, she indeed needed help quickly.

Kira took her first two cumshots in her mouth, you are going to repeat that pattern. Results matter, and they need to happen soon.

Joy sucks you’re cock for ten minutes or so before you tell her gently, “Joy I am close, get ready.”

She looks at you, letting your cock out of mouth briefly, taking a quick breather as she strokes your long dick. “Bring it on doc, I need your fucking cum in my throat big boy...”

She then goes back to sucking your dick, but works it with both hands, while keeping eye contact. Your orgasm rises, and you cum hard in Joy’s willing mouth, and her eyes go wide.

She sucks eagerly, holding onto your cock like a vacuum, finally letting it out of her mouth with a light popping sound.

“Fuck John,” she says, out of breath. “That was different.” Her breathing is faster, she is flushed, and you can smell her body getting turned on.

“How?” You ask her, the details matter.

“I have never had cum in my mouth that hot. I know it is always around 97 degrees, but that was warmer, almost scalding.” She replied. “And it was a lot John, that was porn star volume, you should be proud of it. And then the taste, I can’t describe it, but it isn’t like any cum I have ever tasted.”

“Bad?” You ask her, hoping you weren’t putting Kira through something bad. “And how do your symptoms feel?”

“Not bad, just unique. Not salty, not bitter, not sweet, I can’t describe it for you, I don’t know how,” she answered, her eyes remaining on your still rock hard dick. “It is a pleasant feeling.”

“But I feel relieved, but I have been getting my doses on time, I wasn’t **** yet.”

“So they tell me that your delivery, inside of a woman, is a little bit different than most,” Joy asks, still eyeing your cock, and licking her lips seductively.

You wonder how Kira is handling her new partner, you hoped it was going well. Joy climbs on top of you, sitting on you and easing down on your cock, staring deep into your eyes with her deep blue eyes.

Fucking her doesn’t feel like fucking your daughter, but it is very nice and her body is fantastic. You would do about anything for science, but doing this for science and having it be good? Hell yeah.

Maria is happy that you are doing ok with Joy, but neither of you are all that excited, your temperature hasn’t spiked, it was just a normal orgasm earlier, no fireworks.

Kira has been cooperative, and Miguel does a good job with her in getting her going. He spends several minutes kissing and sucking her large breasts. Squeezing, licking, sucking, they are really quite wonderful.

Miguel then spends a good while performing oral sex on Kira. He really went at it, and Kira seems to enjoy it.

Miguel uses his fingers inside of Kira, and keeps playing with her breasts as he pleasures her. At one point he pulls his fingers out and holds them up to Kira, who licks them clean.

She doesn’t love being here, but she promised to try, and tasting her own juices finally starts to get her going.

Kira soon surprises Maria by returning the favor and sucking Miguel’s dick, but Maria knew that John had told her how important this was. “Good girl,” Maria thought.

Kira kneels before him, and starts licking his shaft up and down, before starting to suck it properly.

She gently squeezes his balls with one hand and works his shaft with the other. She does not make eye contact, closing her eyes and imaging her father’s cock instead.

Kira is really good at sucking cock at this point and the visual was amazing, so Miguel does not last long, cumming within five minutes.

Kira never stops sucking and swallows everything he had to give. She keeps sucking until Miguel is soft, as she does for her dad.

Miguel will need a few minutes, so he kisses her, and then goes back to playing with and sucking her large breasts. He could happily do this all day.

He then went back to eating her pussy out, sincerely enjoying both the taste and smell, not to mention the extraordinary body Kira possessed.

Soon enough Miguel is hard again, and moved between her legs and began to fuck her. She was warmer than a normal woman, but fuck did Kira feel good.

For Kira the sex isn’t bad, but it is not like her dad at all. Fucking Miguel actually feels pretty good, but it does not bring her to orgasm. Not even close.

Miguel however gives her his all, fucking her for all he is worth. Using her beautiful young body, knowing it won’t last forever.

He changes positions often, particularly enjoying doggy style, as the view presented when fucking Kira in this was in quite good. He finishes inside of her in this position several times, pinning her beneath his weight as he saw her father do.

That first day Kira swallows Miguel’s cum twice, and he came inside of her four times, trying to cause the reaction. And he loves every moment of it, but she never orgasms.

Kira was physically more beautiful than anyone Miguel had ever been with, and he gets to watch her beautiful ass shake as he fucks her, gets to suck on her amazing tits, and gets to watch his cock stretch her throat. For him it was great.

She allows Miguel to push his cock into her throat, Kira wants the practice for being with her dad again. And Miguel is a bit larger than her dad in cock size, so the practice should help.

Miguel really loves science right now, watching as Kira lays before him with her head slightly off of the bed, slowly pushing his cock deep into her throat. He loves watching her throat bulge and stretch, fuck this young woman is talented.

Her father is truly a lucky man.

The father and daughter she brought in had been a dud, so Maria quarantined them in the same room, and she figured that at some point the man’s daughter would be able to convince her father to be her donor.

Maria tells them there was is no donor available, and that the communication system is down, but it is a lie. Maria knows the girl is barely old enough to qualify for the program, that is likely a good thing.

She is likely going to be resilient being younger, not being too close to stage two yet, so maybe she has some time to wait.

If they don’t play ball she will send in a donor, but she wondering if she had a way to trick the man into fucking his daughter, or maybe she could get the man to donate and inject it in the daughter where she wanted it, inside of her to try to cause pregnancy. This was going to work out her way, it had to.
