After my encounter with the wolf cub things got a lot better. I felt like an actual living being again rather than an empty sex machine. When I went to the patients after her, I started actually paying attention, noticing their little quirks and charm points. Though I often still had to overpower somewhat unwilling participants, I was able to keep hold of the fact that I was doing it for their good, which made the work lighter. I actually enjoyed myself, sometimes.

Everything was fairly normal for a while until one night, when my patient was a small bear cub. She seemed to be younger than most of my previous patients, and fairly plump. I'm no expert on this or anything but I've heard that the start of puberty is triggered by body mass among other factors. I wondered if perhaps that had something to do with her getting Early Onset Heat faster than most other cubs.

Or, perhaps the Syndrome was spreading to younger and younger cubs as time went on. That wasn't for me to speculate on, but I'd be sure to let the scientists running this program to know so they could think it over.

She was pretty out of it, smiling at me dreamily with half-lidded eyes as I crossed the floor to her bed. Her rich brown fur was a bit mussed, probably from laying in bed for a while, and she was only wearing some soft purple pajama bottoms so her bare tummy poked out like a little muffin top. Her physique meant that, oddly, despite being the youngest of my patients she was the least flat-chested. I wondered what it would be liked squeezing her soft fatty breasts between my fingers while I fucked her.

Since she wasn't curious I didn't bother expaining myself. I got right to work, crouching down to slip her pajama bottoms off. I was just working her thick, light-blue training panties down when I heard the front door slam open.

I stood and turned. It couldn't possibly be the parents, right? Maybe they forgot something?

But in the time it took me to think these thoughts I heard thundering pawsteps racing down the hall toward the room where I was. There was something about them that made my mouth dry with terror.

Whatever instinct that was, apparently it was right on the money.

The door crashed open, practically flying off its hinges. In the frame stood a massive male bear, a full head taller than I was and muscled like a bodybuilder. His eyes were full of wild rage and he was panting, sweat and foam flecking his face and neck.

His eyes took in the scene, flicking first to the cub on the bed, and then to me. Then he roared so loud I thought the windows would shatter, and stepped forward.

I didn't have time to think or dodge or do anything. The roar paralyed me with instinctual fright and then his arm blurred in a backhand strike that hit me like a truck. I heard and felt a loud crunch as I hit the bedroom wall and crumpled to a heap on the floor. I must not have hit my head, though, since I didn't immediately black out.

Perhaps the bear thought I was dead, because he paid me no more mind. Instead he turned to the cub and knelt by her bedside to hug her. It would have been touching if one of his paws didn't immediately start working off her underwear and stroking her bared crotch.

"Oh cubbie cubbie don't you worry, papa's not gonna let anyone else lay a paw on you. You're daddy's little cubbie. Yeah, that' right," the bear growled nuzzling his face against the cub's.

The cub responded in kind, tilting her chin up to nuzzle him happily.

"Daddy~" she murmured, sleepily.

I had seen family photos on the way in and did not remember seeing this bear in any of them. An estranged ex? The cub's original father? Fuck, how had he found out about the heat treatment? Or had he just heard she was in heat and rushed over to fuck her?

Fucking her was apparently his intention because when he pulled off his jeans his massive erection was already shiny with precum.

He wasted no time in lifting her off the bed and sliding her down onto his throbbing cock. She let out a squeal that turned into a moan as she settled down as far as she would go. He, too, let out a long, sighing breath of pleasure as he felt his daughter's pudgy body wrapping around his shaft.

When he pulled her up the coppery smell of blood wafted through the pheremones in the room. No matter how stretchy or lubricated she was by the heat, there was no way she was taking her father's massive dick inside her without quite a bit of tearing.

She didn't care. Unlike when I tried to get my infirtile dick inside these cubs, this was the real thing. She was in heat and she wanted cubs in her belly, and her beloved papa was going to give them to her. Her hooded eyes were intoxicated with love and desire. Her little paws clutched at his shirt as she pulled herself up, helping him ram her up and down on his rod.

Their panting breaths - his guttural and hot, hers sweet and gasping, filled my ears, along with the wet sucking noise of her thirsty virgin pussy demanding his seed.

It didn't take long.

With a grumbled moan of "Oh cubbie, cubbie my baby girl~" the bear sank her as deep as she would go on his cock and I saw his muscles clenching through the thick fur on his ass. She overflowed in an instant, spurts of his thick cum spilling out around his shaft as her already plump tummy seemed to grow just a little plumper.

When he pulled out his dick was followed by a thick stream of cum that dribbled onto the floor and the side of her bed.

Slinging her down on top of her pillows, the bear hunched over the cub and started again, doing her canine style, hands gripping her thighs to pull her hard into each thrust. His giant furry ass obscured most of my view of the penetration, so I could only watch the cub's little face as she gasped for breath between sweet pants of pleasure and moans. Each thrust by her father sent his giant balls slapping against her plushy butt, and the force of their mating shook the bed and the room itself.

When he got close he lifted his cub up off the bed and held her from behind, hammering her up and down, making her fluffy butt cheeks bounce with each thrust.

"C'mon lil' cubbie daddy's gonna give you his babies so you'll never forget, even if they take me away. You'll always remember daddy, right? You'll raise daddy's babies up to be beautiful little cubbies like you, right?" he growled, his voice cracking in the middle as he moaned and came inside her.

He embraced her in a tight bear hug as their bodies shook with his orgasm. The force of his thrusting or the pressure in her uterus must have been too much, as I saw a stream of urine burst out from between the cub's legs. Her squirts of piss made a pattering sound as they splashed all over her bedsheets, and the air was full of the powerful musk of her heat pheremones.

Despite the pain in my body and the situation, the pheremones were enough to give me a massive, throbbing erection. The cub's father, not having any calming drugs in his system, got hit by the full force of this fresh blast of heat scent. It drove him crazy.

Throwing his cub onto her bed and raising her leg, he began to pound her again. She moaned weakly as cum squirted out of her full vagina with each of his thrusts.

"Oh~ daddy~ give me your babies~," she said between pants and moans, her voice weak and exhausted.

I don't know how long it continued. Fully erect and alert, I watched as if hypnotized as the bear reamed his daughter again and again, spurting gushes of cum that had no place in her already distended uterus. Each time he pulled his massive cock out it was immediately followed by jets of cum as her body tried to reject the excess.

He was so desperate for relief he didn't always get into her gaping vagina. He pounded her little asshole more than once, leaving her entire crotch area a mess of creamy white and stretched holes. He jacked himself against her thighs and rammed himself into her mouth, hairy ass twitching each time he sprayed her with his seed.

She stopped responding after only a few rounds with him. Her eyes fluttered closed and she slumped in his arms, but he didn't stop. For one insane moment I thought of telling him that her falling asleep was a sign the heat was satisfied and she didn't need any more, but I was fairly sure he would kill me if he remembered I was there.

After he fucked her once or twice while unconscious, I was afraid he was going to do some real damage to her. But I could still hear her little huffs and gasps of breath each time he slammed her down on him, so apparently she was okay, just completely exhausted.

By the end of it, the end of the big bear using her entire body as a fleshlight and cum rag, she was practically plastered head to foot with his sticky seed. Her fur was stuck flat or brushed up in odd configurations all over her body, and it would probably be an absolute mess when it all dried. Her stomach was bloated, filled from all sides and holes with his cum. White drool dangled from her mouth as she snored quietly on her bed.

Her father, after fucking her unconscious, had apparently also fucked himself unconscious. Rather than finishing, he just leaned forward and collapsed onto the bed in mid-fuck, his dick slipping out of her loose hole and spewing wads of cum onto the carpet of her bedroom floor.

I let a few moments pass in silence, waiting to see if it was safe, then I gingerely stood up. My body screamed in pain when I moved, but I bit my lip and bore it. Everything inside was telling me to run the fuck away but I at least checked to make sure the sleeping bear wasn't going to smother his daughter under his bulk.

Luckily he had missed her when he slumped over, and the two were curled up in a stinking, sweating, cummy, furry mess.

I got out as quietly as I could and called for my extraction.

---

In the end, I wound up in a shady government laboratory hospital being patched up by some of the scientists on the Syndrome team. Apparently that one blow from the bear had broken a few ribs as well as my arm when I hit the wall.

When I was resting, one of the government intelligence agency goons came to visit. He didn't look happy.

"We had to eliminate the father," he said, right out of the gate. "We promised this family we'd take care of their daughter and then THAT happened right under our noses. Now the docs are going to have to figure out what the fuck we're going to do with the cub, especially because the parents are against abortion."

I don't know what he expected me to have done against a bear almost twice my size who had broken half of me with a single hit, but I did feel sorry for the cub. Considering she had basically taken a bath in her dad's cum I doubted there was much chance of her not conceiving. So young, too. Damn.

"We've got a shitton of cubs out there suffering with the Syndrome and despite there being a fuckton of cubphile assholes like you, we don't have an endless supply of nonviolent offenders," he said, then fixed me with a steely gaze. "But if you make us clean up another mess like this I'll take you out back and shoot you myself."

With that happy message, he left.
