Warning: This story does contain sexual coersion and stuff that would be deemed sexual abuse on a teenager. She is not hurt, and I have used every tag warning I can think of. If there is one I missed that you would suggest, please tell me. I apologize now, but you have been warned.
Secondary Warning: Because of this story being about an alpha that's using drugs to alter their chemistry, I want to state now there is some derogatory talk around it, only informational, and I mean absolutely NO offense whatsoever to anyone who is undergoing any kind of hormone therapy for a trans situation. I have total respect for that community and mean no ill will towards them, this is entirely fiction. I don't know what kind of tag I could use to warn against that, but there it is.
Disclaimer: No one in this story is real, the two characters are not in any way based off of real people, no one was hurt in the writing of this. It is not based off of any real events that I know of.
------
Derek had watched his young daughter grow into the smartest little whip he had ever seen. She was only a smart ass when playing, but Rebecca could sass with the best of them and still be respectful when she needed to be. He was sure any alpha that got their hands on her would have to prove they could handle her if they wanted to deserve her. At seventeen, she had yet to present as any classification but she would definitely be an omega or a beta... So he thought.
It was very rare for a female to present as an alpha; any female that did present as alpha would be useless to males because they couldn't whelp.
Then one of the mornings that he woke up to make breakfast for them, she angrily threw her plate to the floor, shattering it and sending food and plate pieces flying all over the place...all because her bacon hadn't been the way she preferred it. They had both stared at the mess in a shocked silence as it sank in what had just happened, and then she looked at him, eyes wide and already filling with a mixture of confusion and regret before she knelt down and quickly started cleaning it up. She repeated apologies over and over, also repeating her confusion at what had come over her.
He had helped her clean it up, speaking in a soothing tone for her while he let her know it was fine. He let her know that he was taking the day off work so he could take her to the doctor and hopefully get some answers; see if this was a warning sign of her first rut coming along or just teenage issues.
Another problem with female alphas was that their rut was just as aggressive as a male alpha's rut, however they were unable to knot anything. Their clits were slightly larger than an omega's or a beta's, which meant more pleasure at least-as if nature felt bad for the cruel prank-but they couldn't properly satisfy the urge to knot an omega. And because of this it was often that female alphas got in trouble for their behavior. The only other option would be for them to go on medicine to calm their tempers.
There were experimental drugs, but they were illegal and only able to be found on the black market. They were illegal because the drugs drastically altered their hormone balance, tilting the scales far from the alpha side until the omega side was nearly on the table. The drugs were also known to cause prolonged heats, infrequent heats, and sometimes heats without a preheat warning; they just wake up burning and desperate for a knot. Their sexual appetites were also affected, ranging from just overly aroused to insatiable until the heat wore off; random over sensitivity of the clit was a frequently documented side effect, and could also lead to orgasms brought on quickly in the bedroom, or orgasms that were completely touch-free. That would be a bonus...not, however, if an important business meeting happened to coincide with the sudden orgasm...
Despite the legal risk, and the risk of the side effects, Derek found his way around the darkest corners of the internet and got his hands on the drugs. The one condition he had was that she had to promise to stop taking them and let her balances hopefully even back out (very few cases could be corrected during the medicine therapy, none had been corrected after) if it got to be too much for her to handle. She agreed, and after three miserable weeks of waiting the drugs showed up at their door. When the summer between her Junior and Senior years finally rolled around, and she had finally turned eighteen, she started the meds.
At first she didn't notice anything, aside from the fact that she was less likely to want to punch a wall, or growl at her father. She had always been close to her father and she didn't like how this rut crap was making her act towards him when he was always able to keep a level head with her even in his own ruts. She wanted to stop feeling aggressive urges around him and go back to their calm, relaxed relationship. In her eyes she had the best dad around, and she didn't want her being an alpha as well to impact what bond they had.
The changes did come though... And she was blindsided by how good her father suddenly smelled, and how their hugs had started being too short for her liking. Figuring it was a side effect of the meds, but thinking she still had everything under control, Becca didn't say anything to her dad. Their relationship had lost its strain, and they were hanging out more again now that she didn't have an issue being around another alpha. If she had known what was going to happen, maybe she might have told her father she had started smelling his laundry before loading it in the washer...or that there was a reason she quit caring about whether or not he was sweaty when he came home from work and hugged her.
The event that really changed things for Becca happened the night she got home from going to her friend's birthday party.
She knew her father had to work in the morning so she had taken a rideshare home and snuck in as quietly as she could, figuring he would already be asleep. She had almost made it to her room when she heard a noise from his room. She stopped, thinking she had woken him by coming in, but when she heard it again her eyes went wide with the realization that she had heard him moan. Becca knew she should keep going, but she was eighteen, a little drunk, and the drug therapy she was trying had something inside her curious enough to take a peek through the barely open door.
Laying on his back in bed, Derek had one hand holding his phone while his other worked his cock, stroking and pumping, sometimes squeezing his head. He worked his way down his shaft to his balls, moaning as he gave them a squeeze. "Fuck yes..."
Becca realized her mouth was practically watering at the same time she noticed she was clenching as if she had him inside of her. She licked her lips and swallowed the need to whimper as she watched his hand squeeze at the knot that was forming as he got close. Her eyes focused on the knot and her clit throbbed hard at the thought of how it would feel to be split open on such a thick cock, and then be stretched even further by a knot. No cum could possibly leak out around it even now, and it looked only half formed. The female alpha squeezed her legs together as her clit throbbed again at the image of her father stuffing that knot inside of her and pumping her full of his cum.
Female alphas didn't have the anatomy to handle a knot, and no drugs could form the space omegas had that gave way for knots, or the slight space betas had. If he did knot her it would hurt, but the thought of such a delicious pain, of her father claiming her body in such a way, had the female alpha soaking her panties with her slick as she watched his hand suddenly moved quicker on his dick.
In his room, Derek threw his head back and moaned as he covered his stomach with thick ribbons of cum, his cock bobbing with the force of his ejaculation. He let his hand drop from his length as he used his other to squeeze and milk his knot, drawing more moans from himself as he rode out his orgasm.
Out in the hallway, Becca made the mistake of squeezing her legs together even more as she watched her father get off. The sudden increase in pressure on her over sensitive clit worked with how aroused she was and set off an orgasm that had her giving a startled, quick moan. Her legs couldn't handle the sudden orgasmic rush and gave out on the poor, drunk girl. She landed on her hands and knees with a yelp as she tried to keep her face from smacking the carpet. Yeah, it was carpet, but even she knew that carpet stopped being soft from certain heights. She blushed and wanted to move when she heard her father cuss, and then what sounded like him scrambling out of bed, but she was too drunk and confused-in so, so many ways right now-to make her body listen to her.
In another second her father was opening the door in a pair of striped pajama pants and kneeling down by her.
"Rebecca, sweetheart are you okay?" Derek asked, half worried she caught him, and half worried she was hurt. "What happened punkin'?"
Poor Rebecca, who was flushed a bright red, couldn't look at her daddy. "I-I uh, I tripped. I tripped..." Fucking christ please think! She mentally begged herself. "I drank too much at Hadley's, I'm sorry Daddy I didn't mean to wake you."
Derek, who was just relieved that his daughter hadn't caught him jacking off, and could focus on the alcohol later, carefully helped her to her feet. All the while he was trying to keep her positioned to where she couldn't see the evidence of his still swollen knot. Pajama pants are notorious for being good tenting material after all, and it's not like there's an off switch for knots. Great when you want to stay inside a sexy lady, not great when your daughter might have an emergency. He shook his head as he realized he mildly envied beta males for their lack of knots and added that to the list of things he never thought he would envy.
"It's okay you little shit." He grinned at her to show he was being playful. "I'll forgive you this time but next time bring me home a shot so I can get back to sleep right after you wake me." He helped her to her room and let go of her so she could lay down on her bed. "Seriously though, you okay? Sounded like you took quite the spill in the hallway..."
