#1 of Commissions

Part One of a commission. If you like my work, please consider commissioning me! The weird spacing is from sofurry; I still can't fix it :/


Friday was 'Fried Day.' Colin had never been fond of this little joke, but for as long as he could remember, his mother had been imposing it on him as a sort of mnemonic. It meant that they were ordering out, namely for fried rice, crab rangoons, and sweet and sour chicken: a golden trio of goodness. His mother claimed it was a "treat" to start the weekend, and it might have been if Colin weren't the one to have to pick it up after school and then carry all those boxes home, or if it weren't the same dinner served every Friday night for as long as he could remember.

"Are you really still doing all this crap?" asked Dusty, Colin's best friend and neighbor for five years. They walked home every day and he was well aware of the routine, but far be it from him to offer help with the burden when criticism was so much easier. "Were you not paying attention last night? The legislature passed! You're the man of your house now, legally, if you know what I mean. Tell your mother to go cook an actual meal, for once."

"You really don't get my mother, do you?" replied Colin. "She doesn't 'believe' in the government. She still acts like as long as she's hiding in the house, she has a choice."

Dusty shrugged. "So put her in line."

"Easy for you to say with one female in your whole household. I've got three, so they think they got me beat."

Dusty, one of six brothers, didn't even try to hide his disdain. "Yeah, and that's easy for you to say. You have two hot sisters and a MILF with a rack that could probably crush a man's bones. I've got my saggy ass mom and eight dicks competing for her."

"Eight?" inquired Colin.

"My uncle moved in last week, fucking leech."

"He moves fast," said Colin, and Dusty nodded.

The truth was that the entire world had moved very fast in the last week, but Colin had not. Dusty wasn't the first to tease him for not taking swift advantage of the new social orders set in place. Females were fast disappearing from public, except for the occasional public shaming. Teachers became public use for students as their posts were filled by qualified men, but Colin hadn't indulged in that either. He had been very patient until this day, even if it meant delivering just one more stinking bag full of greasy fast food.

As they approached Dusty's place, Colin could plainly see why he was unsatisfied. Mrs. Pruitt, a homely but shapely Saint Bernard, was attempting to do the dishes while getting ravaged by her eldest son. He could see at least three more in the window crowding the pair, and even from a glance he could tell they were jerking off with impatience. From their perspective, Dusty must consider Colin the heir apparent of a harem, and he was foolishly under-utilizing it.

"Well, see you around," he said dejectedly.

"Not for a while," Colin said. Carefully balancing the food bag, he retrieved both the mail and a small package from the mailbox. "Now that I've got this, I'm spending the weekend with the girls." He set the tightly packed box, a one-day priority-shipped federally-issued box of Eros Euphoris, atop the Chinese food tower. Right on schedule. It was nice for the government to occasionally fulfill its promises.

Dustin's ears perked up. "Oh hey, I forgot they were sending us that today!"

"I didn't. I'm hoping it'll make the transition go nice and smoothly for them. Call me a benevolent master," he ended with a flourish.

"Liar," Dusty teased. "I've seen firsthand what that stuff does. You're just making it easier for you."

Colin chuckled. "So sue me. I have to work smarter, not harder when it comes to my family."

They parted ways. Dustin had his dick in his hand before he got through the front door, but Colin was too busy balancing takeout and fiddling with his key. His family expected him home at the same time every day, but it was too much effort for them to keep the door unlocked, let alone help him with the food.

Colin had merely one foot in the door before a shrill scream pierced him in one ear. "FOOD'S HERE!" It was his older sister Candace, clear from the other room. Without even looking at Colin, she scurried off to fetch the rest of the family, shouting the announcement with every step like the local town-crier.

In the past he might have grumbled, "I'm here too," but instead he smiled. He obediently laid everything out on the coffee table as he always had, where they'd always been. He even set their drinks according to their favorite spots on the couch. Finally, with moments to spare, he broke into the package with a box cutter. Everything inside was laid out neatly.

Colin set aside half the contents and prepared the first dosage, the Eros. This one was meant to be ingested, and it was designed to be easily and surreptitiously left in beverages. He hastily did the deed. The pills dissolved in a fizzy blur, and within moments the other half of his family appeared. His mother, Allie, and Barbara, Candace's twin sister.

Dusty's words may have been uttered in jealousy, but they were true. The tigress twins, Candi and Barbie, were every inch of eighteen years old. Their fur was practically luminescent, but Colin knew how many hours they sunk into it every day, and he had stopped being impressed. However, summer was getting on, and they were reduced to Daisy Dukes and torn crop tops without even a bra underneath. In this heat! Their melons bulged underneath with perfect obliviousness for present company. They both happily crashed into the couch and their tits both jumped for joy, and Colin saw everything through the thin white fabric.

His mother, Allie, looked like an artist's rendering of the twins in ten or fifteen years. She'd had them quite young and still retained plenty of her youthful glow, plus the impeccable ass that accompanies all devout yoga moms. Fresh from a shower, her amber hair was still damply cascading down her shoulders. Her breasts only appeared to sag slightly from age; they actually sagged slightly from weight. Unlike the twins, Allie avoided form-fitting shirts that sculpted her breasts, and opted for shaggy blouses and muumuus to hide them. It was an impossible task, as they were mountainous mounds and protruded through even the most conservative garments.

Of the four, Colin was the only tiger in the family with white fur and hair. Even his father, long out of the picture, had borne the same striking burnt orange as his daughters. Colin had always supposed that that must make his parents recessive carriers of the gene, and he always wondered whether it had passed to the twins. Either way, his fur marked him as the black sheep he was in the family. He was looking forward to that changing.

Allie pulled her hair back so she could eat, and she absently said, "Hi sweetie," when she saw Colin. She only glanced at him; her eyes were on the food. "How was school?"

Colin wasted no time pressing her buttons. It was a confidence he'd gained only in the past few days after all the changes. "The last changes were implemented today," he said. He bored into her with his gaze, begging her to meet his eyes, but she wouldn't. She did less and less, these days. "All of the girls who haven't dropped out were stationed at our desks today. We learn while they give us blow jobs. It's supposed to help stimulate the brain or something."

"I heard about that from Jenna," interjected Candace, a gob of fried rice already lodged in her cheek. "It's disgusting! I'm so glad we already graduated!"

"Honey, we chew, then talk," Allie corrected sharply. Then, directed at Colin, she said: "I've asked you not to bring these things up."

"Well, mom, that's just what's happening in the rest of the world. If you don't want to know, don't ask me about it."

The twins rolled their eyes with comical similitude, but Allie's cheeks flushed. "Colin, I won't tell you again," she scolded. "This house is the last bastion of sanity your sisters and I have left. Do not bring that filth in here." When she finished she took a sip of her drink, and Colin's chest tightened. The countdown was on!

"He's just trying to get a rise out of you, mommy," Barbie said with an icy glare at Colin. He hardly noticed her; he was watching Candace take a nice, big gulp of her drink, watching the way her lips tightened around the bottle neck. "He's bragging about how the only girl he can get is one assigned to him," she sneered.

"Well, actually, I didn't take one," Colin informed her. "A desk girl, I mean. There weren't enough to go around in the first place, and anyway, and I think it's more of a distraction."

"Good," said Allie in her discontented way. Whatever she said, nothing was ever good enough. "Good. I'm glad you see it that way."

Colin excused himself as the girls dug in. Even now, they treated him like some house pet. They didn't even thank him for the food he brought them every single Friday.

The girls finished their food and drinks over nature documentaries (his mother forbid the news, as it depressed her) and Colin pretended to do his homework. In secret, he observed them as carefully as the researchers onscreen. They were clearly experiencing some of the early symptoms as soon as five minutes after ingestion; he saw beads of sweat gather at their hairline before trickling, and he watched them each start to fan themselves frantically with the takeout menus.

"Colin, can you up the A.C.? Please?" Barbie whined.

"We can't afford to run it anymore," said Allie. "Buck up, hun. It'll pass soon."

But of course, it didn't. As they squirmed, Colin beamed. What an excellent product! Now they could all enjoy themselves instead of rigidly obeying a fool matriarch.

Colin, ever patient, waited the full recommended thirty minutes before approaching his family again. They were quite different; they had all but melted in the heat. Allie's sharp posture devolved to her sprawled out, her legs uncouthly parted. The twins tied up their tank tops, baring their midriffs, and fanned themselves aggressively. He saw their little flat tummies heaving and their perky breasts leaping from all the exertion.

"How are you all feeling?" he asked pleasantly. "You all look a little off."

And in that instant, Allie knew. Something, perhaps simply the instinct of a mother, drew the conclusion for her. Fixing her judging gaze on him, she asked, "Colin, did you do something to us?"

He liked that she was looking at him now. He wondered if she was getting horny yet, and if she had started considering her options for abating her horniness. "I haven't done anything. The decision was made for me."

"What decision?"

Colin, however, was having none of it. "Mother dear, you know exactly which decision I'm referring to," he said, sternly waving a finger at her.

"I know nothing of the sort."

"Well, I'm happy to explain." Colin turned off the nature documentary. Neither of the twins protested; they were more concerned about themselves.

"Mom, he did do something," Candace whispered fervently. "Jenna told me about this too! She said -"

Colin interrupted. "Jenna is a slut who is now too busy spreading STDs to spread rumors. I passed her on my way home from school. It's finally happening. No, it's not just happening; it's happened. The world is changed."

Both Candi and Barbie let out a wide-eyed, breathless little "No."

Colin took great joy in asserting, "Yes." And he took a step towards them.

"Colin, don't you touch my daughters." Allie tried to dash to her feet to protect them, but she couldn't support her weight. Instead she fell and barely caught herself on her hands and knees. She was one step away from Colin, and when he took that step, she was face to face with his groin. His jeans were tented so tautly she could see the threads strain. She took in a breath and was flooded by his hormones, the alluring scent of which was amplified by Eros.

"First, your pituitary gland is reprogrammed to vent constant hormones. Some chemical reactions happen, you enter instant heat. Your judgment, gone. Impulse control, gone. Fine motor skills? Well, you tell me, mother," he said, grabbing her hair and shoving her face into his crotch. "Can you stop me?"

"Colin, don't you dare," she said, half ordering and half begging. Candace was too stunned to react, but Barbie reached out to help.

"Please don't hurt her!" she cried.

"I'm not hurting her; I'm helping her." Colin unbuttoned his jeans and boldly stepped out of them. He held Allie's hair taut, and she didn't even flinch. "I love your hair, Amber," he whispered.

"Fuck you," Allie spat. "How dare you have the nerve to call me that."

"I know it reminds you of dad, but your hair is so lovely! It's inspiring," he added, and he ran his fingers through her lengthy strands.

Allie said, "Colin, I know we disagree on some things, but -"

"No lectures today, please," said Colin. He pulled his mother's potato sack over her head, and she didn't resist, nor did she even try to hide her exposed breasts from her son.

With the rational approach shut down, she promptly swapped to an emotional one. "Why are you doing this," she sobbed. "What have I done to make my boy this way?"

Colin shushed her and tenderly stroked her cheek, and then gently trailed down to stroke her boob. "It's okay, mom; it's not your fault. I'm here to take care of you. It'll be better this way."

She spat, "How could being enslaved and raped by my own son be better?"

"Better than what? You got knocked up at 13 and clung to mommy and daddy for support. Then you did it again at 16, except this time you married the dirtbag and then divorced him so fast I got whiplash in the womb! You haven't done shit with your life," he sneered.

"I brought three children into this world and spent my life up until now sacrificing everything to keep them well," she said. She clearly meant it as her 'last word,' but Colin just smirked.

"Oh, not everything."

The twins were either too weakened by Eros or too shocked to move, so they sat dumbly on the couch as Colin brushed aside the food cartons and then gently laid their mother across the coffee table. He stripped Allie nude, and she lay placidly as he crawled over top of her.

"Stop him!" cried Barbie, shaking Candace.

"Mommy, get up," Candace yelled. "Why aren't you fighting him?!"

"She knows she can't," Colin said. "You'll never be an overbearing control freak again, mom! How's it feel to be so out of control, for once?" He flexed his cock and let it gently bob against her clit. She retracted in disgust, but Colin forced her down and ground his dick against her slit. She was leaking full force now, and the tender wet lips of her labia shamefully throbbed and gripped him with each pass.

"I'm your mother!" she screamed. "Why would you want to rape your own mother?"

"It's pretty simple, I guess. I need to fuck, mother. I've told you this. But you've never given me that, have you? Instead you tried to stop me by throwing out those dirty mags and grounding me when I took your panties. You couldn't even at least let me have that, could you?"

"You're a demon," she whimpered.

"Why would you withhold something I need, mother? Your own baby boy? Even if it's something you obviously need, too." He leaned into her, cupping her breast with one hand and gingerly thumbing her clit with the other. Allie bit her lip and tensed up, but her clit throbbed eagerly under his touch, especially when he roughly began teething at her nipples. Her boobs were suddenly as sensitive as her clitoris, and she squirmed with every callous squeeze from her excited son. "How long has it been since you had a good dick? You're always working, and you don't even have any friends; I'll bet you haven't even seen a dick since high school."

"Please don't do this."

"Fuck, has a man ever even made you cum? I mean, really. Do you wanna know what it feels like?"

"No - " Colin pinched her clit, bulbous and stiff, and Allie couldn't help but gasp. Her breathing was rapid and shallow; it was clearly getting harder to speak. "If you're going to rape me, do it. But don't delude yourself into thinking I'll enjoy it."

"I don't have to delude myself; you already are enjoying it. But thanks for the permission to fuck you, anyhow."

"No!" she yelped, but it was too late; Colin's penis had naturally come to rest against her yielding hole, and ever so slightly, he pushed forward. His head pierced her and a primal cry erupted from both of them: his of pleasure, hers of pain.

"No, no!" Allie would have never imagined that this mammoth erection belonged to her young son, but he couldn't let her forget it; Colin made sure to look her straight in the eye as he kept on splitting her in two with his dick, deaf to her cries.

"Wow," he said. "I'm ashamed of myself."

"Why? Because you've just crossed a threshold of depravity you can never step back from?" There she goes again, he thought. Prose and sentiment. It was too bad she'd walked right into his trap.

"No, I just can't believe I thought you'd have more trouble taking that. I was actually worried I was too big, but your pussy is so loose! Maybe you're more of a slut than you let on, Amber."

Allie didn't reply. Her teeth were grit tight enough to crush boulders and her knuckle bones were bulging from her grip on the sheets, but she could not resist the truth. Colin was right; the pain had struck once and never returned, not even when, faced with a cervical blockade, he had poked and prodded like a battering ram until achieving surrender. She felt every inch of cock stuffing her from labia to womb, even the quivering trails of veins against her walls, and all it felt like was pleasure. In moments he was grinding some disgusting noises out of her, and somehow the pleasure began to override the disgust. Perhaps it was merely the helplessness of the moment; if there was nothing left to do, she may as well enjoy it.

Colin's free hand squeezed her delightfully fleshy boob. She gasped, and he took the opening to kiss her. She only resisted for a second or two before her situation caught up with her, and then she merely refused to kiss him back. Colin ground his hips at a nice, calculated pace and took her tits in both hands. His tongue lapped at hers and coyly bit along her lip, pressing her, chastising her chastity, until she further gave in, and responded to him.

Every time he squeezed her tits, she made the shyest face of astonishment Colin had ever seen. It was as if no one had ever touched her so roughly before, at least not since her mammaries had swelled after childbirth. Colin had sometimes sucked the tip of his finger at night, imagining it to be a tender erect nipple, but nothing compared to the sensation of his lips finally embracing one. It wasn't like how his dick got hard; even though the nipples appeared stiff, they were actually quite soft, and when he pinched and twisted them, it thrilled Allie, and he knew it because he felt her pussy throb around him as he did it. She could hide nothing from him.

Soon, Allie was humming contentedly into Colin's lips with each stroke. She even lifted her legs and her hips to stabilize him, and she pulled his waist tight into her. Whenever she could speak, she begged him to stop, but she never let go of her grip around his waist and shoulders. She clawed into him as she leveraged against his cock, grinding in time with his deep thrusts, and still she plead for mercy.

"I need to stop, please stop, no more, oh god," she moaned.

"Why? Are you getting close? So am I." With that, he doubled down on the table, and picked up the pace. Allie continued protesting, but the table was slippery, and she was weak.

"Colin, please, don't, don't cum in me! Please, don't - !"

"Ooh, mom," Colin moaned. "That's so hot! I'm gonna cum, oh mommy I'm gonna -"

"No!" she screamed, but her legs were wrapped tightly around his hips and she couldn't unlock them. The second she realized she might become pregnant, if it weren't almost certain, her vaginal muscles began violently contracting around Colin's dick. Over and over and over again she came, as if her entire reproductive system were screaming with approval at just the thought of being bred, regardless of the sire.

Colin nuzzled in her shoulder and bit her throat with a hearty groan as his peak hit, and rather than thrust he allowed his mother's orgasmic thrashing to coax him to orgasm as well. Involuntarily, she flexed her hips and squeezed his dick until his seed bloomed in her with one continuous gush, and her innards hungrily milked him deep into her womb. Everything about her body was screaming 'yes,' and still she had the audacity to continuously whisper, "No, no, no."

"Are you worried you might get pregnant?" breathed Colin. "Don't worry. Even if you avoid it this time, I won't stop cumming in you until I put a baby in your belly." He grinned. "Hell, I won't stop then, either. There's plenty of room in your fat pussy alone."

"Please no..."

"You're such a filthy liar! Your pussy is still throbbing; are you still cumming? Was my meat that good?"

"I - I can't help it." Her expression was beautiful: mortified lust was the only way he could describe it. It made his cock twitch, and he relished in the face she made as she felt it jump inside her. "I don't know why I came; I didn't mean to."

"I know, mom. It's okay. This is what you're meant to do; you don't ever have to worry about anything else again."

"Please take it out." She was panting hard; her legs had begun to shake violently from the longevity of her contractions. She was still going.

Colin said, "Stop cumming and I'll take it out."

"Stop..."

"Did 'getting raped' turn you on that much?"

"I can't..."

"Jesus," he laughed. "I'm not even fucking you, you slut; I'm only half-hard." This was quickly becoming a lie; his mother's inability to control herself was too much.

"I can't -!"

"You can't what, mommy dearest?"

"I can't stop cumming!" she cried, and Colin couldn't help but snicker when he heard his sisters gasp at the lasciviousness of their mother's call. He beheld his mother: eyes glazed over, drool just accumulating at the corner of her mouth, and a numb but contented expression of orgasmic bliss.

"Don't worry," he assured them. "You both will get your turn."

Colin extracted himself from Allie. Unplugged, her cunt was still shuddering as it dripped a steady stream of semen on the wood. One hand thumbed her tender breast and the other went straight for her snatch, frantically rubbing and fingering her empty aching cavern. She knew her son was not only watching her, but enjoying it, and yet she couldn't keep her hands off of her pussy. She was begging for her orgasm to stop while flicking the bean with maddening intensity.

"God, what's wrong with me?" she gasped.

"Nothing's wrong," said Colin. "You're progressing along schedule. I told you, remember? This is what you're meant to be and what you always have been: a mother."

"It's just the drugs or whatever he gave me. It's just the drugs. It's just the drugs." Perhaps she meant to say this privately, but she said it aloud, and Colin teased her.

"It's so easy for you to blame me, isn't it? All you have to do is lie there and cum and tell yourself you didn't do anything wrong. You should be thanking me. Do you have any proof I drugged you? How do you know this isn't just who you are?"

Allie didn't reply, but she continued fervently masturbating. She would be useless to him until she recovered, Colin decided. That was fine; his harem contained not only one, but three beautiful women after all. He never felt more grateful for being the only male in his family. He thought of the poor Pruitts having to share their mom, all six of them, plus father and uncle, and thought maybe he could extend a favor to them by offering cheap admission to his sisters. There was no need to be greedy.

Barbie and Candi, drugged, dazed, and in shock from witnessing their little brother raping their mother, did nothing to stop Colin from ripping off their shorts and spreading both of their legs at once. He knelt between them and confidently felt up each of their thighs, Candi's right and Barbie's left, until he reached their exposed genitalia. Like their mother, both sisters were already wet, and it plainly distressed them to realize this.

"I'm not actually turned on! Sometimes it just gets wet down there. It's hot, and I've had a long day!"

"Like mom said, you gave us some weird drugs. Who knows what was in them? It doesn't mean anything."

Try as they might to excuse away their overt arousal, neither of them tried to flee from his tender administrations. They were even more sensitive than Allie, especially when he finally got a finger in each of them and their vaginas both clamped down with some force. Fingering both of them at once allowed them both a chance to get them ready, and him to reach a decision: which should he fuck first?

Colin lapped up the lewd but bashful expressions of his sisters as his fingers pressured their g-spots with persistent roughness. They squirmed at his touch, not away from but toward, and with no reservations. Soon their eyes rolled back and their nipples pulled taut at their tank tops. He couldn't believe the improvement! Given more time, he was sure they would each become obedient sluts happy to serve him.

"Here's the deal, girls. The first one to cum gets fucked first," he said. "And if you don't cum, then I don't fuck you. That should be easy if you aren't enjoying it."

Candi and Barbie both knew that they did not, in fact, want to be fucked by their little brother. However, Colin was already knuckle deep inside each of them, and they had mistakenly allowed themselves to creep far too close to the edge. The mere mention of orgasm sent a tingling all along their lower half.

A repressed and sober part of Candi tried to crawl away, but that moment or two without Colin's determined fingers left her feeling so empty that she willingly pushed herself back onto them moments later.

Colin, however, withdrew his hand from her pussy. Instead, he took up massaging her tits, and while it felt amazing, it wasn't the same as getting fingered. Of course, how could she complain? It was less invasive for him to touch her boob, or so she thought. She hadn't realized just how close she had gotten, or just how stimulating and tender her tits were.

Her genitals kept winding and winding up, and her legs curled, and when Colin began pinching her nipples and pulling at them, Candi closed her eyes and howled as the orgasm ripped through her, fast and dirty and over far too soon, nothing like the prolonged pleasure Allie was still recovering from.

"Barbie, if you're still not convinced you're meant to be my harem, look at your sister. I didn't even have to finger her for her to cum. Was it just from anticipation? Or is she just trying to get fucked first? Which is it, Candace?"

"You were fingering me before you stopped," she whined. "And you...you were touching me..."

"Mhm, so you admit I made you cum not just from anticipation, but from fingering you to that point."

Candi flushed red, bemused and ashamed, and then Barbie begin to whimper like a young kit, for Colin had begun manhandling her clit as soon as Candi came. She had no chance. It was very short work to draw out an equally quick but powerful orgasm, Candace gazed enraptured at her jerking hips and curling toes, and just like Allie, she too absently reached for her own cunt and began masturbating with both hands.

"Oh, I see," said Colin. "So you came from watching your sister get off, is that it? You must've already been all hot and bothered after watching me fuck those hot screams out of our mom." Now finished with Barbie, Colin turned Candi over on her knees. She was putty in his hands, still shuddering, pussy dripping. "Either way, since you came first, I guess that means you get my dick!"

"Candi, why?" Barbie cried.

"I don't know. I feel strange."

"You're just not used to your new normal," he assured them. "This won't seem so strange once you get used to it."

Colin began to situate himself behind Candi, and she spread her legs, revealing her puffy red sex to him and him alone. She didn't have a single quip for him. He held his tip to her entrance and rubbed his blunt head against the hot flood until his length was well lubricated. One glance, and he already knew it wouldn't be as easy with the twins as it was with Allie. His sisters weren't exactly petite, but their sexes were clearly smaller, and his fingers had already confirmed they were tighter.

Still, he thought, even if he could only secure a few inches in them, that would be enough to inseminate them. He could train them afterward to take him, and with any luck, they'd enjoy it.

"Alright, Candi," Colin said, patting her ass genially. "Since I'll be busy using your cunt, how about you get Barbie ready for me?"

Neither of them moved or replied. They were each shaking and avoiding his gaze, and Colin impatiently humped Candi for a response. "Just let her sit in front of you and eat her out," he pressed. "Candi, do I have to get rough with you?"

At that, Allie clumsily shambled over, legs weak and streaming with semen. She was gingerly fondling her breasts, and Colin licked his lips at the sight. "Colin, can...can I get Barbie ready?"

The twins looked vaguely horrified, but Colin was pleased. From his perspective, Allie wasn't bargaining or sacrificing herself; she was just helping because she had gotten too horny to just watch. Her progress really was astounding.

"Well, since you asked so nicely, I guess you can. I'm a reasonable guy."

Barbie protested, but her mother swiftly held her down. "It's for your own good, dear," she said.

"Mommy, why are you helping him?" she sobbed.

"I'm not, dear. I'm helping you. Your brother is very big," she said, and Colin swelled at the hot flush in her cheeks as she said this. "He might hurt you if you aren't ready. I'll make it feel good, honey."

"Mom, I don't want you to -" Allie's head ducked between Barbie's thighs. Her dexterous tongue first found and assaulted her engorged clitoris, twirling and suckling the bulb from the hood and Barbie, not fully recovered from Colin's fingering, came instantly with a shrill scream. This second, sweltering flash of pleasure left her dumb and blind for an agonizingly long moment, and when she came to, it was to the sight of her sister getting nailed from behind by Colin. She couldn't respond; she gaped at Candi and weakly mewled, "Mommy, I don't wanna cum anymore, I, ahh..." as her mother progressed to eating out her pussy with ravenous abandon, and then she couldn't speak.

"Good job, Amber," Colin said after Barbie's fourth consecutive orgasm. He and Candi watched them all; he made sure of it by pulling her hair to keep her head up. "That's really hot. If you keep that up, I might just have to reward you. Candi likes it too; I can feel her pussy quivering every time you moan, Barbie. It's like she's cumming in sympathy with you."

Candi, by this point, did not merely like it; she was voracious. Colin had underestimated his mate. She couldn't fit more than seven or eight inches of his cock, but she took what she could well, and to his great delight she wouldn't stop trying to stuff more of it in her. She clawed the couch and slammed herself into each thrust, grinding against him and pushing until her tongue and eyes were practically bulging out.

Colin probably would have already cum had Candi not obviously wanted him to continue so much. But all good things must come to an end, and Colin finally ended Candi's first fuck by spraying her cervix with his pent-up load. Candi, craning her head to watch, could see what remained of his rod pulsing with each squirt. She wasn't afraid of the warmth filling her, or what it would inevitably do to her; she was just disappointed that this meant her brother wouldn't fuck her anymore, and feeling full of his hot sperm was making her unbearably horny. She clenched down on him to keep him still, but Colin managed to unstuck himself simply by softly cupping her breasts and pulling at her nipples until she melted into the mattress.

Allie and Barbie had twisted into a sixty-nine by the time Colin came for his last bitch. She was laying on her back and sucking her mother's taint, cluelessly allowing her thoroughly-used pussy to spill semen all over her face. She was also unaware that Allie had stopped returning the favor, and was instead peeling apart Barbie's labia to give Colin a target. She sat on Barbie's face to keep her still, and Colin grabbed her hips and gingerly aimed his fat head against her yielding hole until it took.

Again, Colin couldn't get much more than halfway inside. But this time Allie was hovering over her daughter's pussy, alternating between tonguing her clitoris and staring at the sinful union while enthusiastically squeezing and flicking her nipples. Barbie continued lapping up her brother's sperm from her mother's thighs, and Candi, not remotely sated, was masturbating while watching. The family had come together at last, Colin thought as he finally emptied his nuts into Barbie. She filled up quickly, and he allowed his cock to slip out and let loose a few rogue squirts on Allie's face before he grabbed it and aimed it into her mouth, which she opened tacitly.

"How's it taste?" he said gruffly. "Mom? Barbie? How does my cum taste?"

Neither of them answered, but Candi also wanted to know. "How does it taste, mommy?"

Allie let Colin's softening cock drop from her mouth. Cum trailed down her chin to her tits. "Good," she said in a daze. "It tastes so, good dear. So good."

"So good," Barbie weakly repeated. "Oh, my fucking god it's so hot!"

"Give it to me," Candi whined. "Mommy, give it to me!" Candi pushed Allie to her back and began licking up the cum trails on her breasts. Colin just stood back and enjoyed the sight of his sisters both swarming their mother's breasts for his fresh seed, much like his cubs would soon swarm to theirs for milk. From the look on Allie's face, their suckling was getting her close. She longingly gazed at Colin's limp penis and didn't even look away when he caught her stare and held it. It was, after all, her turn.

It was the final symptom: an addiction to semen. That meant it was time to deploy Euphoris, although Colin was in no rush. He already had his very difficult family under control and, with any luck, impregnated. The rest of their transition would go smoothly indeed.
