Maybe you saw this ending coming. Maybe you wanted this ending to happen...but it all comes down to this, in the final installment of this series for CertifiedGSD!
All grown up and getting ready to head off to college, Gertrude was a late bloomer all the way through her formative years, and even as an adult, she's a little late to a certain party. While her mother is out of town yet again, she finds herself in need of motherly advice as her first heat strikes...and even after several masturbating orgasms, she feels no relief.
Without another woman in the house to seek advice from, she goes to her father instead...but the bast laid devices of nature are more than she can resist. When Askim naturally resists, Gertrude reminds him that she has one wish left, leaving him between a wall and his own heated daughter.
What's a father to do...?

If there was any flaw in the family that Askim, Asker and Gertrude built, it was the fact that certain things would always be out of their hands.
Throughout their lives, Asker was forced to miss a number of important moments due to her career obligations, and naturally, Gertrude drifted closer to her father as a result of this.
She still loved her mother, and other than the occasional spat that one would expect in a growing family, they weren't ostracized...but at the end of the day, Gertrude was Daddy's little girl, even when she was finally all grown up.
Asker was fortunate enough to be in town for the graduation ceremony, where more than a few people mentioned how much Gertrude, now more often referred to as Gertie, looked so much like her mother. In the pictures that were taken of the proud parents standing on either side of their wonderful daughter, their family resemblance was uncanny.
There was a greater connection, however, that couldn't be seen in any picture. Underlying thoughts were creeping into the back of Gertie's mind as she grew older, and classes in school told her that such things were natural, but she'd always taken care of them on her own.
In that way, Gertie was glad when her mother left town; her father slept early, and that meant she didn't have to stay up too much later to know she could moan in delight as she dipped back into the world of self-pleasure.
"They weren't kidding...n-not one bit," she gasped, as her digits continued eagerly spreading her labia apart. A third finger dipped between and hooked up as she penetrated herself rapidly, but all in vain as she started toward a second orgasm. "No matter what I do, it doesn't quit...it...j-just doesn't fucking stop!"
Sexual education courses told a girl what would happen to her during her first heat, but most teachers were still loathe to encourage a growing teenager to seek out ways to handle the waves of desire that they'd be riddled with. Early in her teenaged years, Gertie didn't feel those sensations as much, and as she grew older, she never found a boy that she liked enough to give a chance to...but now, as a fully grown woman of 18 years, she found herself gasping and trembling in the covers as she tried to get rid of the insatiable desire to be fucked and bred.
Nothing was working, and forbidden thoughts were starting to flood her fantasies; she got that from her mother, completely unknowing that she was a product of incest...and that she was about to repeat the cycle.
She didn't believe what she was thinking, but she was already acting on it as she sat up from her covers. A puddle of her juices already stained the comforter, and the trail of desire followed her thighs as she stood upright and gazed down at herself.
She was _definitely_her mother's daughter, and for a moment, she quietly wondered if Asker had such a body when she was that age.
The right person to ask was lying in bed, pretending to be asleep...but he couldn't hear Gertie sneaking down the hall over the sound of his program. The light of the TV was the only thing illuminating his room, and his door was just faintly cracked open, allowing Gertie to sneak a glance at her father before she gave the reins over to her instincts.
He certainly didn't look his age, for a man in his 40's. She was sure of that much, even before the rose-colored lenses of passion forced her to see him as the only male within reach that was fitting to be inside of her.
Whatever bit of resistance she had left was completely dashed by the sight of her father's bulge against his briefs, the display certainly not meant to be an enticing one...but he didn't know he had an audience.
"D...Dad?"
His ear perked immediately, and he shifted the covers over his groin. "Heh, uh...y-yes, sweetheart?"
His eyes went wide, and his jaw dropped as Gertie pushed through his open door without a scrap of clothing on her body. Before he could realize his own modesty, he'd seen the trickle of fluid lust spilling down between her thighs, the sight of it burned into his mind before he blocked his vision.
" Gertie! Wh...What the hell are you doing? Put some clothes on!"
His reaction would have filled her with shame any other night, but she wasn't a little girl anymore, and even if her thoughts told her that taking a step forward was wrong, her body was determined to prove that she was ready for this.
"They're in the wash," Gertie lied, her tail lifting a little bit further and starting to wag as she drew closer to her own father. "Won't be ready for a while, I'm afraid...but I've thought of a really fun way to pass the time until they're done."
Askim knew her scent well, and his canine senses were picking up on something that he'd only ever noticed on her body in passing. Like a proper gentleman and a good father, he ignored the extra hint of lust on her natural aroma anytime he noticed it...but this time, it was flooding the bedroom and leaving him desperate to smell anything else.
"Gertie, you are not yourself, sweetheart. I...I know what you're going through," he tried to sound like a knowledgeable parent, even as her ripe, fertile body drew closer to the bed and leaned over it. Her open palms spread over his sheets and tugged back at them playfully as he slid back toward the headboard, fearful of what he might do if they touched. "It's perfectly natural that you're seeking out relief, b-but...but I am not the right person to come to for that!"
She never slowed. Where Askim gave up his grip on the covers, Gertie kept pulling until her father's boxers were exposed again; even without an erection to tent them, his bulge looked particularly delicious that evening, such that Gertie licked her lips as she put a knee on the bed and began to crawl.
"And I suppose you'd rather have me out and about, sleeping around with all the guys my age?" she asked, her hips swaying eagerly behind her as she crawled further still. "None of them would be able to do what you can do, Daddy. Who knows how many of them I'd have to go through before I was satisfied?"
"Sweetheart, t-that is n-
"All the trouble I could get into," she carried on, "All the risks I'd have to take...you don't want your little girl going through all that, do you?"
Askim felt like he'd gone back through time, looking at the spitting image of his wife in her younger years. The resemblance was so strong that her paw was all the way on the inside of his thigh before he reached out to grab her wrist and stop her.
He knew it would be his last chance. "Gertie, we can't do this. I know your first heat is difficult, but this isn't how you should deal with it! You need to develop a good sense of willpower now so that you can handle yourself when your mother and I aren't around to help keep you distracted!"
"Willpower, huh?"
Gertie snapped free of her father's grip and pushed the heel of her palm against the slowly growing bulge in his briefs. "What's that you were saying about willpower, Daddy?"
He couldn't help the physical response to her scent, or the sensual touch of her paw. He sucked in a tight breath as her digits smoothed over the growing shape of his covered cock, the last fibers of his logic and reason tearing slowly like the final strands of a life-saving rope.
"Listen, Gertie...I...I'm your father. You're my daughter. We just can't do this; do you understand?"
A quick tug allowed his growing member to spring free from his briefs, the canine flesh dripping as she admired it hungrily. "You are my father," she agreed. "And you still owe me one more wish."
In the heat of the moment, Askim didn't believe his ears.
"You could use that wish on anything you want. You're my little girl, and I'd never deny you a promised wish, but this...n-not this, Gertie."
"You said anything I wanted," she repeated the words, "And...I know why you're hesitating. I know it's wrong...you're being a good father...but I'm scared, Daddy."
He was floored by her honesty. "Scared?"
"I've never felt anything like this. I feel like if I don't do something about it soon, I'll make a mistake with someone that I really regret, someone that I don't love," she confessed. "But if you see me through this, I promise I'll learn to control myself. I mean it."
Gertie was a strong, young woman, so much like her mother that it was just a little eerie for Askim.
All that being said, he couldn't help being proud of her, and though he knew it was wrong, he was flattered to be the subject of her final wish.
"N...No one can ever know about this," Askim finally replied, his voice riddled with pleasure as his daughter began stroking the base of his shaft. " Ever."
Gertie nodded. "I understand, Daddy."
"Good," he replied. "Then stop stroking my cock."
"Huh?"
Demonstrating the shape he was in, even in his 40's, Askim pushed Gertie over, prompting a giggle from her as she landed flat on her back. She thought it was going to happen then and there, but like the loving father he was, he scooped her up in his arms and stood up from the bed before grabbing something from the nightstand and carrying her up to her room instead.
It only seemed right that her first time would be with someone she loved and trusted, in a place where she felt safe.
"I can't believe we're really doing this," she whispered into his ear, her arms wrapped tight around the back of his neck.
He knew that her words were dripping with a lust that she couldn't control; he was still getting past his own hang-ups, but the moment he touched her naked warmth, he knew that he wouldn't be able to stop himself.
He set her down gently on the bed and saw the messy puddle that she'd left before, prompting not only further arousal from him, but further compassion.
"We certainly are," he murmured, easing his briefs down as the full length of his canine member grew erect from the sheath. "My poor little girl is struggling with something, and her father has a wish to grant that will fix everything for her."
Gertie would have been suspicious that her father seemed so into the idea of an incestuous coupling. She had to get over weeks of shame at the fantasies she'd been having, fully unaware that she was the product of such an act in the first place.
In the midst of her heat, however, every fetish was a turn-on. "Is it really that simple, Daddy?"
"Not quite," he admitted, as he kneeled over the edge of the bed and revealed the object he grabbed before. The foil wrapper of a condom was discarded as he slipped it over the tip of his cock, and Gertie watched with lustful eyes as the pulsing length drew closer to her eager, quivering folds. "But getting knotted will help your body pretend that it has what it needs...you'll be able to relax until your next cycle comes."
A nervous gulp was hidden behind an uneasy, but eager smile. "Knotted...? You mean it?"
"It's the only way to be sure," Askim leaned all the way between her spread thighs and slipped his arms under the small of her back, pulling her hips up. The very tip of his length kissed against her parted folds, and each of them sucked in a gasp as they sat at the point of no return. "And you'll love it either way, trust me."
She nodded with feverish desire as the warmth of a real, flesh-and-blood cock teased at her womanhood. Her heat demanded a hard, deep penetration; her knowledgeable father eased his length forward instead, feeling out the first couple inches of her passage with his tip and learning her body before he dared to go any harder.
The first touch, subtle as it might have been, was enough to shatter Gertie's world completely. "D...Daddy..." she whispered breathlessly as her smaller frame was pulled up gently into his own. "How c-could anything feel t-this good?!"
"That's simple," he eased a little further in as her breasts touched to his chest, their bodies nearing the apex of penetration after a few slow, easy thrusts. "This is as close as you can be to someone that you truly love, Gertie. To share something l-like this...how could it not feel amazing?"
Her parted folds delicately bounced, and then settled against the fuzz upon the edge of his sheath as she took the whole of her father's length with a soft, pleasuring thrust.
She knew he had to pull back to keep going, but her arms flew to his shoulders and grabbed on tight, wishing that she could feel so completely full until dreams carried her off to sleep.
"Makes perfect sense," she tried to sneak the words out, rushing them before a heavy gasp left her fighting for air. She sucked in tight and clenched her inner muscles on her father by instinct alone, and though it nearly pushed him over the edge, he kept gently bucking forth on his knees, knowing that he'd already gotten her close. "Fuck, D-Daddy...please go a little h-harder!"
Waiting for the signal and finally receiving it, Askim was shifting from a caring father to a cautious lover. Keeping her hips lifted for the perfect angle of penetration, he planted his knees firm and bucked forth against her, his full, swollen sack bouncing against her inner thighs as he gave her the first real thrust of the evening.
Her eyes shrunk down to tiny pits as pleasure like she'd never imagined left her entire body tense around him. Where she would have hesitated to draw things out, he just kept going, pumping his hips again and slamming into her with such force that her breasts heaved against his body, her tender nipples brushing through the fur upon his torso and adding a new element of delight to the act.
She was certain that she'd just gotten off, but her entire existence felt fluid, as if she'd transcended the restraints of her physical form to reach a new, higher pleasure. There was a relief that she'd never known possible through climax, but her father knew that she needed just a little bit more than that to be truly satisfied.
Her heat was persistent, and he was determined to quench it for her.
"Hard enough for ya?" he asked, his voice tainted with a new sense of ferocity as his own canine instincts began kicking in. Her inner muscles fluttered at his shaft, squeezing and milking it whenever she could, but as his pace picked up, her inexperience kept her from getting a grip.
She could only cling to her father in desperation and revel in a pleasure that only he'd ever been able to bring her. Her arms were getting weak, but even when her grip slipped and she fell away from him, he didn't give her an inch to breathe.
He knew she was ready. His paws shifted to her hips and held her tight, keeping her body from sliding back in the least as he started to pound into her deflowered sex like the lust-driven beast that he was. A half-smile graced Gertie's muzzle as her form bounced and heaved with his every pass, her mind and body content to ride out the ongoing waves of ecstasy as Askim did his best to breed her.
"It's p-perfect," she moaned, her voice like a distant memory to her father as she looked up at him with pleading eyes. Even when the impressive weight and girth of his knot began stretching her labia, she looked as though she was riding a high that she'd never come down from, and her body did just as it was meant to, accommodating his bulb with a tight and eager pop.
She was so lust-drunk herself that she hardly noticed the way her father was trembling against her, until he was leaned over her body, his hips trembling but unable to move back as thick, virile cum poured inside of the condom and filled it to capacity in the first couple throbs. She was greedy in her own pleasure, her body limp against the bed as he bit down on her shoulder, muffling his own groans of delight and reducing his voice to a powerful, rolling growl.
I can't ever undo this, he thought. I can never look back from here, but she looks so happy...was it really that wrong?
The thought danced around in his head as they panted against each other, neither one quite sure what to say as her heat began to subside, and his knot slowly deflated. He made sure not to spill his own mess, and Gertie widened her eyes at the sight of his voluminous yield as he tied off the condom and tossed it away.
"I...I bet it feels really good to let that happen inside, doesn't it?" Gertie asked, finally breaking the awkward silence between them.
"It's pretty amazing, yeah," her father agreed.
"Could we ever...y'know...do that?"
Askim was so convinced that this would have been a one-time occurrence that he didn't stop to think how much he would have enjoyed it, and now that it was done, he had to reconcile with how much his daughter enjoyed it.
With her mother gone so often, there was no doubt that temptations would arise again.
"When you're off your heat, if you really want to try it that badly, I guess we can."
To see such a genuine, affectionate smile from his daughter brought joy to Askim, but something else happened when her paws cupped either side of his muzzle.
Her kiss was more than he could resist, and just as his length was starting to retreat into his sheath, it immediately throbbed and began pushing forth again, until it poked Gertie's inner thigh.
"Mmn..._mm..._Oh!" she broke the kiss as she felt the delicate touch, giggling up at her father and giving his cheek a soft caress. "I'm sorry, Daddy. I didn't mean to rile you up again...I just couldn't help myself."
He smiled bashfully. "That's okay, sweetheart. I'm sure you're still a little riled up yourself."
"I am," she paused, giving his side a gentle nudge. She couldn't have turned him over on her own, but getting the idea, he willfully rolled onto his side, and then his back as she moved to straddle his hips. "And after what you just did for me, I think I owe you a little favor."
Askim never would have wished for something like this to happen, but as his daughter unrolled another condom and began sliding it over his growing length, he was suddenly glad that he didn't have to.
**
"So, who's the new target?"
Askim was slaving over the stove as Christmas dinner was getting started, and Gertie was quick to run up and hug her father from behind. Strolling in a bit more nervously was Felan, the aforementioned target.
"Oh, Daddy...Felan's a nice boy, I promise!" she told him as she kissed his cheek. She released him so he had a chance to turn back and gaze upon not another canine, but a snow leopard, the long, heavy fluff of his tail completely puffed up with nerves. "He's treated me so well this year, I just had to invite him to meet you guys!"
"A feline, huh?" Askim couldn't help playing the tough dad roll as he pointed to a chair. "Why don't you take a seat and tell me what your intentions are for my daughter, hm?"
Asker strolled into the kitchen just in time to tug Askim's ear. "Oh, no you don't!" she scolded him before greeting Felan with a warm, welcoming hug. "It's so great to finally meet the boy that's captured my daughter's heart. Let me fetch you a drink, dear!"
Silent and dying of nerves, Felan took a seat at the dinner table. He could see how close the Shepherd family was, but he missed the sneaky, narrowed gaze that was shared between father and daughter before Gertie sat next to him.
If she was sure enough to bring Felan to Christmas, then Askim had finally gotten a wish back from his daughter: that she'd meet someone who made her as happy as she made him.
