By the end of the second day after she arrived, McKinsey's heat was in full swing and Larry had seen to it that she had been thoroughly fucked into exhaustion and had fallen asleep full of his cum, with his cock buried deep inside of her to help ensure she would carry their child. By the time he had knotted her for the final time of the night the mixture of their fluids had begun to leak out around his cock, and it only made him want to replace what had been fucked out of her. Had he not been exhausted as well, he would have made the attempt to replace what had been wasted by leakage.
What had started as him flirting with the idea of keeping her pregnant, using her as his own personal breeder, was a real plan now as he dominated and controlled her body. She was so receptive and responsive to his actions and domination that there was no way he could let her go.
His other daughter Ally, the first experiment in control that got stolen away by his younger brother Vernon, had never been as eager and responsive as McKinsey was, and this omega seemed to be more in tune with her omega instincts. She was more of a natural omega than Ally, and now he was actually glad his brother had come along and taken out the trash for him. No matter what training he could've done, Ally would have never gotten anywhere near as perfect as McKinsey was for him.
She had surrendered to him all on her own, without years of manipulation, rewards, and punishments. Even her pussy had welcome him in its hot, tight embrace and dutifully milked every last drop of potent sperm into her fertile womb. Every time he took his little girl he could feel her pussy becoming the perfect fit for him; her body's own way of silently urging him to breed his new mate. Soon she would be his perfect cock sleeve, a day he anticipated.
He had thought he was bullshitting his daughter when he had told the omega her body knew who she belonged to but, every time he took her, the fighting came less and less until she had fully submitted to him. Her scent was so weak compared to his that his scent was already overpowering hers and combining with it to make a scent that marked McKinsey as her father's omega. Anyone who took a whiff would know for a fact her father was also her alpha, and that the pair were serious about trying to conceive while their cycles were in full swing.
Larry knew that breeding was easiest to achieve when both partners were in their cycle, as it meant they were both at their peak fertility, and he saw to it that she spent the rest of his rut on any surface they got horny near.
That was another area McKinsey differed from Ally. His previous omega had only liked sex in the bedroom, but McKinsey let him have her on any counter or piece of furniture he damn well pleased.
When he had been watching TV until she woke up from a much needed nap, he got a pleasant surprise in the form of McKinsey riding him on the couch as soon as she had woken up and left her room. He hadn't even been hard when she came out and knelt between his legs to suck his cock to life before impaling herself and riding him until he'd given her a generous cream pie, sealed inside of her by the thick knot she loved to squeeze and squirm on. When his knot had begun to go down she rode him again, all the while urging him to cum deep in her, to knock her up and fill her breasts with milk for their pup. She had let him lay her out on the kitchen table and devour her pussy as she moaned and begged for release, wanting her alpha to make her feel good.
Whenever he found himself needing a break he would secure his load inside of her with a plug, giving his seed the best chance at taking root. Sometimes even having her lay on her back with a pillow under her ass to help guide his cum where it belonged, while his fingers worked her clit and nipples until he pushed her over the edge into an orgasm that would suck his swimmers right where they belonged. And, much to his surprise and sick delight, she begged him to sleep with his cock inside of her anytime he could, needing to feel her Daddy filling her even when he wasn't actively fucking her. Though, good little slut she was turning into, McKinsey couldn't last long with her Daddy just sitting inside of her and soon she would begin to move and squeeze until he either came inside of her again, or pinned her and rutted into her to spend his load. It pleased him, more than she knew, that she was so needy and desperate for his cock. It was a nice change of pace from Ally just responding to her alpha's advances.
Unfortunately, because his rut had arrived days before her heat, they only had three days of being on their cycles together. That meant that when it was time for Larry to go back to work, McKinsey still had a day or two of being in heat left. But he was determined to make sure was pregnant before the end of her heat. He just needed to figure out how to get the next few days off from work to ensure he had her for the rest of her heat. After having Vernon steal away Ally while she was in heat, Larry wasn't all that willing to leave McKinsey alone at the house - it didn't matter to him that no competition was around, he was too paranoid. Not that he would ever admit it to himself.
On day four of her heat, Larry woke his daughter as he had every morning since she arrived, with his head between her thighs while he enjoyed his new favorite breakfast. He loved the taste of their combined juices leaking out of her, even more so when a flood of fresh arousal began mingling with the remnants of each previous night's breeding session. Her fingers tugging at his hair, and the desperate whines and whimpers he was drawing from her, pleased his primal instincts and told him everything he already knew. He owned her. He thought he might have to remind her as such once she was out of heat, but he would find that out the answer to that query in a few days. Until then, despite today being his first day off of his rut, he was an alpha on a mission to breed his omega and carry on his line.
McKinsey spread her legs wide for her father's assault, moaning loudly as his tongue stoked every fire in her body. She had already cum moments ago, but it was clear her alpha was determined to wreck her with another as he showed her body who made her feel good. It was proof she couldn't ignore, that no one had ever made her feel good, not at all like this. Every part of her felt like it was on fire, she was hyper aware of everywhere his hands were, and how good his rough calluses felt to her sensitive skin. The hand that held her in place, as if she would be stupid enough to try to get away from what felt so good, held her hip firmly as his other hand worked two fingers in and out of her soaked and abused pussy.
The fingers inside of her stroked back and forth over her g-spot until they achieved their goal and McKinsey arched for her father once more, screaming from the intensity of the orgasm being pulled from her already overstimulated body. The fingers stilled inside of her, but Larry's tongue continued to lap at her, making her twitch and squirm under his actions. Like the good omega she was for her alpha, McKinsey no longer stopped him when she was overstimulated and he wanted to keep going. She had learned her lesson that her pussy belonged to her alpha in every way possible.
Pleased with the panting mess he had turned his omega into, Larry moved up between her legs to cover her body with his own. His leaking cock smeared a streak of pre along her thigh on the way up, and when she gasped and still pushed her hips up to him, Larry wasted no time in lining up with her entrance and thrusting in. A deep groan left him as her wet heat welcomed him back inside with a tight squeeze that almost made him blow his load early. "That's my good omega," her father rumbled as he held his hips still while she desperately lifted hers, seeking to draw every inch of his cock deep inside, "you love your Daddy's cock, don't you?"
"I do." McKinsey gave a breathy moan when his cock pulsed inside of her, releasing another dribble of his pre cum, and she made a noise of agreement in her throat as her nails raked over his back. The action made Larry inhaled sharply in a mix of pleasure and pain. "I love my alpha's cock, and his knot...want to be his cock sleeve." She squirmed beneath him, turned on by her own words. "Please fuck me Daddy, need you to breed me."
It was alien to Larry, to not have to be in his rut cycle for an omega begging for his pups to turn him on, but McKinsey had sewn her own seeds and didn't even know it. Every omega he'd slept with he had to coax into eating out of the palm of his hand. But this omega had put up a fight and he had dominated her. He had even given her his mark when he'd fucked her awake two days ago, and it still made his balls ache when he saw the jagged but healing wound that claimed her as his omega. He didn't love her, but he did thoroughly enjoy how much of a perfect partner she was.
Even now as he took her with hard and deep, dominating thrusts that rocked her body below him, she was still clawing at his back in ecstasy and crying out to him. She begged for his knot, for his seed to be pumped deep and get her fat with his offspring. She called herself his slut, despite the way she had lashed out and tried to escape when he first took her. She had submitted to him, and she had the same stamina that he had, something Ally had never been able to keep up with. His younger daughter had taken his cock well, but McKinsey was practically made to be his toy with her ability to play as long as Daddy needed her, and she proved she was eager to do so. His release was achieved quick in his excitement, and even though his knot was plugging her before McKinsey had reached her own orgasm, he got the pleasure of watching her climax from being filled her alpha's knot.
