Work on the cure, and try to provide treatment and comfort.

You spend your morning at a laptop, scouring the available data. At the morning briefing, you ask what is known about vaginal delivery, and if data exists on the frequency of symptom anomalies, like nymphomania.

There is some data to use, it turns out that vaginal delivery is actually very effective, likely more effective than oral, but has not been mentioned publicly to avoid the risk of pregnancy. Also, it was thought that oral delivery could be done clinically, and non-invasively.

There is some good news at least, Kira was at least given an effective dose. You hoped they would have some data on her descent into what looked like sex addiction or nymphomania. But this was something to start on.

You work through to lunch and then head home to check on your daughter, stopping by a pharmacy to buy a small portion of plan-B pills on your way home.

When you get in the front door, Kira runs to you and smothers you in a hug, wearing her robe. Her beautiful form fitting robe.

It looks beautiful on Kira when it is covering her, as it is sleek and form fitting, but it opens as she runs to you, now showing part of her amazing naked body. Those amazing breasts, Jesus Christ those breasts are a gift from above.

She is holding her naked body directly against yours tightly, you feel her warmth.

"Hey daddy, I missed you!" She kissed you on the lips, and you feel her tongue in your mouth. You shut the door, accept the hug and return the kiss. You pull away finally, "Hey baby, how are you feeling?"

"Great so far, you ready to give me my afternoon helping?" You notice she is a bit sweaty, which is odd, the house is cool.

“Are you feeling ok baby? You seem a bit warm.” You ask, is she running a fever?

“I feel great dad, maybe never better, I am just horny, I have been all day.” She answers in a melodic tone of voice, “I have been trying to get myself off for a while today, but it isn’t working.”

"Let's have some lunch before we do that, And I picked something up for you at the store," you continue, showing her the plan-B pills.

Kira smiles and laughs, "Oh daddy, I don’t need that," she replies, "I am on the pill, I have been for a while."

"Birth control?" You stammer, "But you said you were not having sex!" Was she having sex? What the fuck, how much have you been working?

"It isn't just for birth control dad, it also helps to regulate my cycle," she replies. "It makes my cycle shorter and more reliable, which is good. It keeps me saner, and I have been on it for three years."

That was something you knew, but just hadn’t considered with your daughter.

At least you didn't already get her pregnant, that was something. You kiss her on the forehead and head to the kitchen to make some food, but Kira has other ideas.

You feel her wrap you up from behind, holding you tight. "I'm not hungry dad, not for food at least." You feel your cock twitch, and she felt it as well, as her hand is on your cock right now.

You turn to her and see she has dropped the robe and is standing before you naked. My god, she is beautiful, her mother would have been proud. "Kira, we shouldn't keep doing this," you say, looking down into her beautiful eyes. "You don't have to do this with me baby, I don't mind the normal delivery at all, I don't mind the glass, my needs don't matter here."

Kira gives you the best fuck me eyes you have ever seen, "Who said anything about your needs dad? This is about my needs, and I need you to fuck me."

She walks over to the sofa and bends over it, offering herself to you. Your cock is rock hard looking at her big muscular ass. She looks back at you, "I want you to fuck me dad, I want you to fuck me with that big hard cock, as hard as you can. I want you to cum deep inside of me.”

You walk up behind her, having picked up her robe, your intent is to cover her with it, but that is not what your hands do. Your hands betray you, they drop her robe on the way, and instead grab and squeeze the perfect ass presented before you.

“Fuck me dad, put that cock inside of me and fuck me,” Kira says breathlessly. “Cum in me, put your cock in my throat, do anything you want but please fuck me!”

You give her big ass a smack with your right hand, and marvel at the lack of jiggle, and the complete lack of any fat on it that you can see. Her ass is big and round, and somehow it seems to be solid muscle.

You squeeze her ass with both hands, and it is amazing, to look at, to touch, you imagine it bouncing against your pelvis. Fuck, what has happened to your mind?

Kira is on her hands in front of you, she didn't unzip you, but your cock is out and hard, and it is resting between her beautiful ass cheeks.

Soon you find your left hand is rubbing it against her wetness, probing the entrance to her body.

"Fuck me, daddy, fuck me with that big fat cock..." Kira says, and you find yourself doing it, your hands are now on her beautifully wide hips, guiding yourself into her and out of her. What the fuck is happening to you. This is the opposite of what you had in mind, why is your body reacting this way? Kira keeps talking to you, "Fuck yes daddy, give it to me, fucking pound me dad!"

You are now gripping her hips hard and you are giving her all you have, as hard as you can give it to her. Your skin is lighter than hers, and you are fascinated by the difference in skin tone. The tone she got from her mother, being half black and half Vietnamese is exotic and sexy as fucking hell.

Kira has stopped talking dirty to you and is now moaning, something of a guttural growl, as you heard last night. You feel her start to shake again, and moments later you orgasm harder than you ever have in your life. Your balance fails you, but you catch yourself with your daughter's big ass. You see stars briefly and feel like you might have blacked out for a moment, and you feel something you never have before with another person.

You feel an emotional connection with Kira at this moment you never had with her mother, you feel her need for you, and her love for you. You can feel her fear at this disease, and her relief at this moment, both sexually and in having another preventive dose of semen inside of her. At this moment you want to keep your cock inside of her, and never take it out.

Kira's body is shaking again, as she is rocked by a powerful orgasm, she cries out in pleasure, and your voice joins in.

You have no doubts right now, Kira is yours and you are hers, and nothing can ever change that. You ease out of your daughter and realize that you are still cumming, and step back in shock, and try to catch it with your hand. Kira turns to complain and sees that cum is still coming out and dives to her knees and takes it in her mouth, sucking out the remaining cum. She hungrily sucks out the remaining life-sustaining seed that she had pulled out of you.

She moans as she tastes it and sucks you until there is no more, then she cleans your hand with her lips and tongue, and then gets down and licks the cum off of the floor that you missed. You keep a clean house, thankfully, and that is fucking hot.

Finally, Kira collapses on the floor, and you carry her to your bed, but you notice that your cock is still as hard as it was before. This is not normal for you, or for any man that you have heard of. You lay her down gently, and she rolls back onto her back, with the contented look you have seen before. "Oh my fucking god dad, that was amazing," as she says this she is gently masturbating herself. with a finger in her pussy, and the other hand playing with a nipple. "I love you so much dad," she says as she absentmindedly plays with her body.

Your cock twitches at the sight, you swear you have never seen a sexier image than this one. No porn could compare with your daughter, your little girl, all grown up and spread out for you.

You ease down and kiss her on the lips, tasting the saltiness on her tongue, you know what it is and you don't care. You go down and kiss her breasts, sucking and squeezing them, as if they contained a life-saving essence that she could give to you. You then look up at her, "Eat me out daddy, I want to feel your tongue inside of me." she says to you.

Your mind registers that you just came inside of your daughter, it will taste about like her mouth just did, but your body doesn't listen to your mind. You kiss your way down to her navel, then she spreads her legs and you see the most amazing looking pussy you have ever seen. Youthful, tight, with her clitoris visible to you. "Well she tasted herself when she sucked my cock after fucking her," you reason with yourself, but your mouth is already at work.

You begin to gently kiss and lick the outside of her pussy, and then you lick and tug at her clitoris with your teeth. As she begins to gyrate her hips, trying to **** your tongue to do her bidding, you begin to go deeper inside of her, but it doesn't taste like your cum, it just tastes perfect. Like the best dessert you have ever had, but better, one with a taste and an aroma you cannot begin to describe.

You eat out your daughter, and a few minutes later she orgasms, and she squirts, right into your mouth and on your face.

You again see stars, and your balance fails you. You almost pass out, feeling an intense wave of pleasure.

Kira pivots and kisses you immediately, and then hungrily cleans your face of her fluids. Without speaking you lay on top of her and enter her again, your cock easily sliding all the way into her, but as before it feels perfect like it was designed specifically to be inside of Kira. It feels warm and intoxicating, and perfect.

You hold a passionate kiss with your daughter as you drive your cock inside of her, again and again, you drive into her. You and your daughter say nothing during this time, however when you finally cum deep inside of her, you both are overcome by the power of your orgasms.

You hold your cock deep inside of her and steady yourself, and you again hear Kira howl in pleasure. You again see stars as you experience pleasure greater even than earlier. You were meant to do this, you were created to do this exact thing with this young woman.

And the world goes dark for you, as you fall asleep quickly, collapsing on her beautiful body.

You wake up later, in your daughter's arms, she is awake and playing with your hair. She is naked, beautifully naked. Wonderfully naked, physical perfection in your eyes.

“Good morning sleepyhead," she says joyfully. Fuck what time is it?

You look for your phone, and find it on your night table, it is 5:00 PM, how long were you out of it? "Fuck, I had work baby..."

"You are OK daddy, I texted them from your phone, I told them you weren't feeling great," she replied. "They said to enjoy the weekend."

Your mind races as you try to put together all that happened, you remember every detail, every single one. You can remember clearly every thing done between you as if you are watching a reply.

What is happening to your body? You are aware of Kira's sweet breath, you hear a bird flying, and then see one go by the window. How the fuck did you hear it fly? What is happening to your senses?
