They do, they are a good two days.

Maria turns and walks out of the room, not wanting to see this at all. Monitoring was needed, but the wireless monitors were applied and that would have to be enough. Cure or no cure, this was offensive to her traditional sensibilities.

Maria would analyze results, but she would not be made to even watch the thermal scans of the event. **** was was wrong as it gets. She secretly hoped you would end up in prison for how she believes that you corrupted your daughter.

You turn back from Maria to your daughter, who has already stripped off the garments she wore to bed, some tight boy short panties and a tight little t-shirt that barely covered the bottom of her large breasts. She looked good in them, she looks better naked.

Kira is standing in the light, fully naked, and as beautiful as ever. Now you see a hint of her abdominal muscles, and if anything her waist looks thinner, and her breasts larger.

Christ those breasts were going to kill someone. Large, perky, full, firm, beautiful nipples which are perfectly round and wonderfully positioned on her breasts.

Other lab staff are less concerned than Maria, and you see people watching through an observation window. You can feel the men and women’s lust as they look at your daughter’s naked body.

“Who cares,” you think, “this isn’t for them, this is for you and your daughter.”

Kira looks beautiful as always, and drops to her knees before you as you take off the comfortable clothing you have been wearing, a pair of pajama pants you like and a comfortable t-shirt.

Your cock is freed from your clothing and bounces up to attention.

Your daughter begins to suck your cock, savoring a taste she has been denied for almost a full day. She takes it out of her mouth and looks up at you, with a loving look on her face, “I have missed this dad, god you taste so fucking good!”

Your beautiful daughter goes back to hungrily sucking your cock, her head bobbing in and out in rhythm with her hand, it is exquisite.

After a few minutes, you put your hands on her head to stop her, drawing a complaining stare, “we will get to do plenty of that sweetie, as much as you want, but you aren’t the only one who is hungry here.”

You pick up Kira and lay her down in the bed, and move down between her legs. You cannot miss her scent as you kiss your way down her inner thigh, the wonderful smell of her arousal.

You feel like you get as much pleasure as she gets when you perform oral sex on her, and you do so now with gusto.

Kira writhes in pleasure, squeezing her large breasts and holding onto your hair tightly. You hear her vocalize as she gets close, and she howls in pleasure and you taste her orgasm. The flavor is wonderful, and you continue to work your tongue inside of her, trying to enjoy as much of it as you can.

She then smiles widely as you rise up and kiss her, lining your cock up with her, then gently inserting yourself into her waiting sex. It is just as warm as before, almost hot, but it doesn’t hurt at all, it feels glorious, like it was always meant to be there.

No sooner are you pumping your clock into your daughter, then she rolls herself over on top of you, now riding your cowgirl style. She bounces up and down on your cock, aided by your hands on her hips, and with you trying to match her by thrusting up into her with your hips.

It is a perfect symphony of eroticism. Your amazing daughter, with a body that appeared to be getting even better by the hour, was bouncing on your cock hard, her large firm breasts bouncing gloriously.

You cannot resist the visual, and you squeeze her tits as she rides you, slowing her down to gently fuck her while sucking on one and then the other nipple. You think they might have gotten just a bit bigger.

You lay back down, and she lays down on top of you, gently working herself over your cock, and kissing you deeply. Your tongues probe deep inside of her, and you use your hands to help her hips do their work.

Your daughter has never been fat, being involved in athletics, but with her big breasts, wide hips and big muscular ass she has never really been lean, but you feel an even more firm ass than before at your finger tips.

You wonder if a side effect of this new strain changes metabolism and musculature as well, perhaps it is where your endurance has improved recently, as you found yourself able to perform sexually for longer periods of time with less rest than ever before.

Kira pulls up above you, and lets you know she is ready, as you begin to get close to orgasm, she knew before you did. As you find release, you again hear the long slow moan from Kira, she arches back and squeezed one large breast, while rubbing her clitoris, and your again see stars as you deliver your seed deep inside of your daughter.

It is a beautiful agony you both feel, the warmth, the passion, the pleasure, the physical love you are expressing to each other. But you both know it will be over soon, it never lasts long enough.

You are not out of breath, but you again fall into a post-coital slumber, you and Kira in each other’s arms, your cock still inside of her body.

Maria has been following your vitals, and is amazed by the results. Your body temperatures, your heart rates and oxygenation are all way out of the normal range. Way above normals.

And the temperature inside of her is something surprising, it might be warm enough to cause discomfort for a man, but you seem not to have noticed at all.

The other staff who observed from the observation room sits in silence, processing what they just saw. Some are bothered by the ****, most are aroused. Even the people bothered by the **** are for the most part aroused, Kira is that beautiful.

The male nurse who has been tending to Kira, the beautiful man she chose to be her partner for her test for his resemblance to you as a younger man, is dumbstruck.

Kira looks like a pornstar. Big breasts, tight waist, wide hips and a big muscular ass, and now her leg muscles and shoulders are finding tone.

The young man is excited by his upcoming duty, and cannot wait for his turn, he get’s to have two days of Kira just to himself. She just has to accept him, he is sure he can manage that.

He will do whatever he has to, and he will make the most of his two days with her. He is going to fuck that young woman like he has never fucked anyone before.

Maria is engaging in a little social engineering here. She chose Miguel for him looking a lot like a picture of you at around twenty, when she first met you. Maria had him leave a little facial hair as you did then, she has him wear a necklace similar to yours, use the mouthwash you do, and she has him use just a little of the cologne you tend to very lightly apply.

Her hope is that Kira will accept Miguel, allow him to penetrate her sexually, and hopefully draw the same physical reaction.

She wants to know if you started the change in Kira or if she started the change in you. Was it possible to extend this strain to other people who were suffering from the disease. Could Sperma KirasProclivitas be spread and save lives.

Maria felt the job was easier for you, you being a man, and chose a young intern in the program, a beautiful little blue eyed blonde. About your daughter’s height, and with a great build named Joy. Maria knows this intern is paying her way through school as a stripper, and knows she recently contracted the disease. Both should do just fine.

Both Miguel and Joy are eager to take part, with Joy having no complaints with the vaginal penetration. Both are hoping to advance their medical careers.

Maria and her staff process the new data as you and Kira sleep, based on interviewing you and Kira, she knows this might take a while.
