Yes, normal is very far gone.

You lay back and watch as your beautiful daughter Kira puts her lips around your erect cock, and begins giving you a handjob while sucking on the tip.

Even with a dick in her mouth you are struck by how beautiful she is. Her beautiful eyes are on you, her full lips looks great on your cock, and you can feel her large breasts on your legs.

She doesn’t move her head much, not being experienced at giving blowjobs, but it doesn’t matter, you were close when she started sucking your dick.

You groan in pleasure as you release a torrent of cum into her mouth, and she doesn’t let up at all, she keeps jerking your into her mouth and sucking the tip of your cock as you experience a toe curling orgasm.

She moans in pleasure as your cum enters her mouth, you can see how much pleasure she is feeling.

After about a minute she rolls over, shaking and moaning in pleasure herself, experiencing another powerful orgasm of her own. Kira is playing with herself again, you now notice she wasn’t wearing anything at all when she got into your bed, and you see her spread her legs and scream in pleasure, as she squirts onto your bed.

Again she lays back, enjoying another relaxing post orgasm moment, but then she rolls back over to your now softening cock, and gently sucks it, trying to extract more precious cum from inside of your cock.

She looks up at you and lets your cock out of her mouth, “Thanks dad, I feel so much better,” she gives the tip of your cock a loving kiss and then snuggles in close to you.

You are conflicted, she is asleep again quickly, but you aren’t so lucky.

What the fuck just happened? Patients were known to go trough this, but she was exhibiting some dangerous symptoms. Some new symptoms.

You knew deep down it was the disease causing her actions, but what about your actions? What about your thoughts?

You feel horrible about your part in this, but what else can you do? You consider involving her in a test program your team is working on, which is far more invasive for the patient, but is intended to try to shock a patient out of her behavior, and into a more normative state.

But this would involve other men, you being a lead on the research team and the patient being your daughter, you would certainly not be allowed to participate.

And that program involves multiple men at once, penetration sex, both anal, vaginal and oral, and doses of semen from multiple donors at the same time.

You could not watch Kira lose her innocence in that way, certainly not her dignity.

You consider involving the normal donor program while she is in school, as it is a long time between her going to school and you getting off of work. That would hold her over and maybe keep her symptoms at bay, but she looks like she is going to orgasm at each dose.

Having that happen at school would be humiliating, and you knew some members of the staff, including her principal were in the donor program. You worried about potential **** of the system.

In the state she is in after she has tasted cum, she is very susceptible to romantic advances, and almost anyone in her presence would probably get what they want from her.

From what she told you, her Principle would try something, and in her condition post treatment she would be powerless to resist him. Yeah, her principle would fuck her quite happily.

Another option would be the parent / student lunches, as this was common. You could provide her a dose while she was on lunch, in a safe and private environment, and then let her finish her school day in safety.

Having a lot to ponder, you don’t sleep much at all, and you are awaken again by your daughter, who is wearing a robe, at least she isn’t naked.

Your eyes are now adjusting to the room being bright, and your daughter is laying next to you with her hands under her chin. “Hey there sleepyhead,” she says to you in a sweet tone. “Gonna sleep all day?”

Your eyes take in her form in her sleek robe, as it rises and goes over her very nicely shaped ass.

“Hey baby, sleep well?” You reply, still unsure of what to do.

“I did, I haven’t slept that well in a while, and I had a dream,” Kira replies. “I don’t dream much, and I don’t remember it, but it was a happy one.”

You would have to do some research and see if there is any data on dreams, relating to treatment and stages. “Well that’s good I guess, what’s up Kira?”

“We need to talk dad, about this treatment,” she says to you. “I have a request for you, just a few things. But I need them, I have to have them, and I have a few ground rules for us.”

“Go for it baby, whatever you need,” you reply, ground rules are good, she has always been smart. Maybe smarter than you.

“Ok dad, rule one, no wasting it, no wasting any of your cum. Not one drop, for anything,” she says, with a serious look. “No donating to anyone else. No using it for studies, and no jerking off on your own. I know you have needs, but I need it all, everything you can produce.”

You give her an odd glance, “Why?”

“You said more is better, so I want more, I want all of yours,” she replies. “And since I don’t want some strangers cum, you are going to have to make enough. I did some studying on it, there are some things we can eat to get you making even more.”

“I can deal with that, unless at some point I can’t make enough, then we call in help. Deal?” You counter.

“Deal,” she replies. “Two, I think we need to plan for when we do this, to make it last as long as it can. From when I got it yesterday evening to when I woke up early this morning, and then to now we’re about six hours each, so we need to plan for that.”

Go you Kira, the looks and the brains, you are proud.

“So I am thinking last thing before I go to school, so before we walk out the door, or I get it in the car while you drive me maybe, but we need it to last as far through the school day as possible.” She continues, she has really planned this out, you wonder if this in on her whiteboard in her room.

She actually probably did chart this on her whiteboard.

“Maybe at school, we can work that out, and then after school, before dinner, and just before bed.”

“Jesus Kira!” You say, a little louder than you planned. “That is a lot sweetie, I don’t know that you need that much yet.”

“Dad, every six hours would be four per day, I am suggesting five, maybe six,” she replies, clinically. “I am allowing for the baseline I need, plus a bit more just to make sure I do not progress, that makes sense right?”

Well fuck me running, it does. She should probably get at least five, and with her abnormal symptoms for this stage, making her wait longer than six hours could be bad.

“I have a suggestion then,” you reply. “You can have your first dose here in the house on school days. I will pick you up for lunch every day, that will be what, five hours after I drop you off?”

“I like that, it makes the school day feel a little less stressful, and avoids me sucking your cock at your work...” She stops, realizing what she just said. “I didn’t mean it to come out like that, I just mean we can then wait for you to get home from work, but you can’t be late.”

“I can live with that baby,” you reply. “So what do you have in mind to get through the night? That is longer than six hours.”

She looks away from you, “I will need to move into your room dad, I need to be right here,” Kira says. “So you cum in my mouth just before bed, and you have seen how it puts me out, and then the hunger will wake me up. I will get what I need first thing in the morning.”

“But won’t that mess up the rest of the schedule if it is too early?” You ask your daughter.

“Well fuck,” Kira replies. “I won’t be able to wait in the morning dad, you won’t believe what is going on, how fucking horny I get. How horny I am right now to be honest.”

“Tell me Kira, we are doing research, I can compare it to other known stage one anomalies,” you reply.

“Well I am usually just fine, like normal, but it starts creeping up on me, a hunger, and I start getting all hot,” she says to you. “I masturbated last night and it didn’t help, I couldn’t get off, I had to have your cum.”

“Well you needed semen Kira,” you reply. “It doesn’t have to be my semen, not mine specifically.”

“It does have to be yours dad, I don’t want some strangers dick in my mouth, or inside or my ass,” Kira replies. “And dad I am thinking about your cock a lot, like all the time. What it looks like, what it tastes like, what it would feel like inside of me,” your daughter closes her eyes, breaths out and you see her squeeze one of her breasts. “Your cock is beautiful dad, and I love how it tastes.”

She said inside of her, fuck. Not her fault, not her fault, not her fault.

“And I think about your cum dad a lot, this is where it is getting weird,” Kira continued. “I am thinking about drinking cum, but all the cum dad, all that there is. I have been thinking of other men as well, whomever, which is why I need you to help me control this.”

Fuck that is not normal, you think.

“So you like my body right dad? I remind you of mom or something right?” Kira asks, “So I will sleep in your room naked, and you can do anything you want to me, anything at all, as long as we can do the rest of this.”

It isn’t just her late mother, Kira is more beautiful than her mother was. Not as tall, but her body is amazing, and she has the most beautiful face you have ever seen.

Kira has a face for modeling, and a body for porn. Her eyes are beautifully shaped and a lovely shade of green. She has full lips, a wide smile, great teeth, great skin, beautiful silky hair, exotic facial features suggesting her Asian bloodline, and her breast. Jesus Christ her breasts.

You pull your gaze back up to her eyes quickly, and she smiles and continues.

“I’m serious dad, I’m horny all the time, I don’t care what you want to do, I will do it with you, or for you,” she replies. “You can do anything dad, suck my tits, eat me out, I don’t care.”

“You can even fuck me if you need to.”

“I have been watching porn and doing some practice, I can try to be enough for you so that you don’t need to date any other women.”

“Practicing what? And what do you mean about me dating?” You answer, this was going sideways. “Baby you have to be careful with porn, it isn’t like that in life.”

“Dad I know you have needs, more than just jacking off, and I know I am asking too much here, which is why I am offering what I have to you. My body, any way you want it.” She answers sweetly, “I don’t want you wasting cum on any other women, I need it all, so use my body if you have needs. Anything you need to do, it is with me.”

You are shocked as she continues, “if you need to suck on breasts, suck mine. If you need a fuck, you can fuck me, but I need every drop of cum your balls can make.”

Jesus Christ.

“I don’t get it baby, what are you worried about?” You ask, “I will do whatever you need, my needs aren’t a part of this. And you don’t have to offer anything special.”

She drops her gaze from you, “I know I am not offering anything special dad, I get it,” Kira replies, in a dejected tone. “But I will give you whatever I do have.” She said this, while getting up to her knees and climbing on you.

And then took off her robe.

Jesus, she is always beautiful, in the light even more so. You have never seen such a beautiful woman in your life, or in videos or pictures. It isn’t even close, you have never seen a more beautiful face on a magazine, or a better body in playboy or on porn.

“Dad you can do anything you want to my body, anything you can think of. I will learn how to do whatever you want me to,” she says to you, sounding ****, like she thinks you will say no.

“You can fuck me dad, whenever you want, you can put it in my ass if you want, I will learn to put it in my throat,” she continues. “I saw than men like threesomes, I will try to learn to do that for you if you want dad.”

Your look of surprise must have been obvious, but you didn’t know what to say. Jesus was she advancing a stage right now?

“Dad I would be with another woman for you if you wanted me to, men like that don’t they? Women doing things with women?”

“I have seen women be with two men, if you really want me to do that I will. Any woman you want, any man you want. I will do anything dad for you dad...”

“Ok Kira,” you say, pulling her in tightly and holding her close, stopping this before she says anything more.

“You don’t have to do all of that, I can provide for you baby, and I won’t make you see another donor. Not unless your life depends on it.”

This is the disease talking, in her specific case, she is one of the rare anomalies present who orgasm when they consume semen, but who sometimes develop some sort of nymphomania along with it. It was dangerous, you weren’t sure what to do.

“Do you need some now Kira?” You ask your daughter, who is holding you and crying lightly, you hope a dose will pull her out of this.

Kira pulls back from you and smiles, nodding her head up and down. “Fuck yeah I do dad, what do you want me to do? Anything you want dad, put your cock anywhere you want to.”

“Kira, darling,” you said, looking for the right words. “I just want you to be healthy, and we can handle that.”

Kira was crying on your shoulder, holding you tight, “Baby I love you more than anything in this world, and I will move a mountain if I have to to save you, you have my word.”

You ease her away from you gently, so you can look her in the eyes, “But you don’t have to offer me anything, I’m not going to use your body just for my own urges, and we aren’t going to have sex. We can’t.”

She seems a little sad, but she is probably as horny as she has ever been in her life. You cannot **** the trust you earned with being her father for all these years. Your body wants her in that way, right now you are imagining fucking yours daughter.

But you must deny yourself to try and protect her innocence, as much as you can.

“I am your father, that is too much sweetie, I won’t ever ask that of you,” You say gently, “but we can do other things, just not all of them.”

Kira looks up at you and pulls you into a deep kiss, her tongue darts into your mouth and she tastes really good. You embrace her on instinct and your hands go to her round ass and squeeze it hard, and it feels really nice in your hand. Really nice, firm, muscular and round, fuck you have to get ahold of yourself.

Kira’s hand slides down to your cock, and one of your hands leaves her ass and moves up to squeeze one of her big breasts.

Big, full, firm, perky, good God she has a great set of tits.

Soon the two of you fall back to your bed, making out passionately.
