The thing that most surprised Jeanne was not how easily she fell back into her daily routines, how casually cruel her son was to her or even the increase in her bust size (she’d gone from a C cup to a D cup in a the week and a half since taking the pills, and was fairly certain her cunt had tightened significantly), but how much she had begun to enjoy herself. If she closed her eyes and let her mind wander, she could concentrate on the sensations of Jack’s cock in her cunt, the intensity of his balls slapping her clit as he rammed her every night, instead of the fact that he was her son. Jack (with the help of the pills) brought her to new erotic hieghts daily. The weekend had been the worst; the effect the pills had on her finally reached a crescendo, and she needed to swallow Jack’s cum every four hours or she began to lose herself again. Jack hadn’t been kind about it either.

No, Jack had taken advantage of her most desperate times by making her do things that would once have disgusted her, but now only aroused her. The thought of fingering her daughter Cassidy made her wet after hours of Pavlovian teasing and indoctrination. She was made to repeat how much of a slut she was and how much she enjoyed being used by her own children for thier perverse sexual amusement. The worst part was how easy it was. Jeanne had come to accept that her new life was as Jack’s slut, and Jack’s slut would do anything for his sweet cum.

It was Wednesday morning, which meant that after Jack’s morning blow job she’d need to cook breakfast before Lily woke up. Jeanne silently opened the door to Jack’s room, walked to his bedside and pulled back his covers. The sight of his cock was both beautiful and terrifying, but she was instantly aroused. She could feel her mouth salivating at the thought of tasting his cum, but she knew that Jack liked her to suck his cock nice and slow, and as she was often forced to repeat “What Jack likes, Jack’s slut gets him”.

She took him in her mouth and slowly, wetly moved up and down. The taste of precum as his cock hardened was glorious. She shuddered in orgasm, and remember that Jack had said that the drug was out of her system, but her brain was already permanently rewired to respond to his semen. There was no escape, and that just turned her on even more. Jeanne placed her hand around the now-ridig shaft and began slowly stroking the cock as she pumped her mouth up and down on it, her spit and slobber making it slick and slimey, her speed increasing with Jack’s breathing.

As he approached orgasm she felt Jack’s hand grab the back of her head and force it down as far as it would go, almost gagging as Jack’s dick made it’s way into her throat. She felt it twitch and unload, spurts of cum sprayed directly in her throat and in her mouth as he let her up. Jeanne didn’t dare stop sucking until the very last drop was taken from the member, for fear that during the day when Jack wasn’t there her cravings would begin again and she’d lose herself, falling back into the wanton behavior that she so desperately had tried to hide from Lily, her youngest daughter.

Cassidy was already another slut in Jack’s stable (a fact that Cassidy herself was fond of reminding Jeanne of, usually as she forced her mother to lick and suck her pussy) but Lily was still untouched and innocent. The mother had avoided her youngest daughter since the previous weekend, when Lily had heard her masturbating loudly for hours and went to stay at a friend’s house for the night. Neither had mentioned it since and it was now a source of tension between the two. “That’s enough. You can leave.” Jack groggily grunted as he turned over and went back to sleep.

Jeanne stood, smoothed her dress, and headed downstairs to begin breakfast. By the time the bacon was cooked and the eggs were frying, Jack had dressed and arrived downstairs. Without saying anything he approached her from behind and lifted the hem of her dress. She felt his cock, already hard again, press against her cunt. “You’d better make me cum quick, before little Lily comes down,” he whispered, leaning in next to her ear as he forced his way into her. As always, Jeanne was sopping wet and stood paralyzed. Jack had forced her to stop wearing panties or bras so he had easy access.

“Wh...what do you want me to say?” Jeanne asked as he slowly pistoned in and out of her, “What would turn you on?” Jeanne knew she needed to be quick, and didn’t have time to guess.

“I need something new. Something wrong. I want to see you be the ultimate slut,” Jack increased his speed, frantically entering and exiting her cunt. “I want you to help me fuck Lily,” he said.

Jeanne stiffened. “No. She’s too young. You can’t, please-” Jack stopped. He pulled out of her and waited. “I—I’m sorry Jack. Mommy will be a good slut. I’ll...I’ll do it,” she said in abject surrender, “So long as you fuck me, I’ll do it.” Her son slammed back into her.

“Yes...God, YES,” Jeanne shouted, unable to control herself, “Fuck me and I’ll help you, I’ll make a little slut out of her, just for you!” Jack plunged into her a final time and filled her with seed. Her knees practically buckled. Cassidy, dressed in an extremely low cut black top under a sheer fishnet blouse (something she would have flipped out about had Jack not tamed her to his will) was leaning against the refridgerator watchin.

“Jesus Mom, what a slut!” Cassidy said, looking down on her mother. “And now you’ve got Jack’s sights set on Lily. You’re willing to sell out your own daughter just to satisfy your lust. Fuck whore,” the girl spat in disgust. She nuzzled up to Jack, who placed a roaming hand on her skirt-covered behind.

“Don’t worry Cass,” Jack said, “I’ll get to you once we get to school. As for the bimbo here, let’s leave it to her to decide how to get these to Lily.” The boy brought out the container of ‘Vitamins’ that she hadn’t seen for so long. “Use as many as you need to, but I want her begging me to take her virginity. And soon.” He started to sit down, but then looked up. “Oh, one more thing. Don’t take any more. My friend says you run the risk of breaking your mind, and leaving nothing but a slut and a few personality traits if you take any more.” The thought made Jeanne instantly wet again. She stood and hobbled to the table, still recovering from her brutal fucking, and picked up the bottle as Lily skipped down the stairs.

“Hiya Mom! Morning Cass, morning Jack,” the blond said enthusiastically. She was wearing her cheerleading uniform (she had just gotten accepted onto the team), and filled it quite nicely. Her breasts weren’t as large as Cassidy’s drug augmented globes, but Jeanne could tell that she’d soon be breaking hearts all over school. Or she would, Jeanne thought, If I wasn’t such a weak little slut With that, she slipped one of the pills from the bottle into Lily’s eggs. God forgive me.

Lily inhaled the eggs without noticing, barely pausing to notice that all eyes were on her. “What? Ish there shomthing on my face?” she asked, mouth still full. “I’m eating fast cause I’m late...”

“No dear,” her mother responded forlornly, “Finish your breakfast and go to the bus.” Jeanne waited until all of the kids finished, and kissed each goodbye in turn. Lily got a quick peck on the lips and headed out the door, Cassidy leaned in and gave her a kiss on the cheek, lingering long enough to say “Tonight, you’re going to lick my clit while Jack fucks my cunt,” and grab her ass before walking on. Jack waited until Lily was out of site, then grabbed Jeanne’s face and brought it to his lips, forcing his tongue into her mouth. “We’re going to fuck Lily’s mind, then fuck her body,” he said, then walked out.

Jeanne sank to her knees and began to cry, both at the horror of her situation and the frustration from her constant arousal. After a few moments to collect herself, Jeanne stood up and began going about her day, her arousal increasing steadily as she did. The first couple of hours at home were spent worrying about the horror of corrupting her daughter, the next two about justifying it in her mind and since then all she’d thought about is how hot it would be. She couldn’t wait to turn her daughter into a slut, making her eat Cassidy and suck Jack. The thought of fucking her own daughter (and worse, fucking her mind with those pills) drove her crazy. The mother’s hands found their way to the now familiar landscape of her lower lips and began drawing slow circles.

Concentrate, Jeanne suddenly thought to herself in a moment of lucidity, You can’t do this to your daughter! If you keep giving her the Vitamins she’ll be turned into a wanton slut, fucking anything with a cock and letting Jack drill her, pumping in and out of her tight little cunt until he sprays her with cum and makes me eat it out of her dripping pussy... Jeanne’s moan was load and her orgasm strong, the last thought in her mind before she passed out a resolution that she was going to do Jack’s dirty work, but she’d do it so well that Lily wouldn’t mind being fucked. In fact, before Jeanne was done with her, she’d be begging for it...

Lily opened the door to her house and stepped inside. At this point, she was used to putting up with the sour attitudes of her horn dog brother and sister, especially with Cass’ new found sleaziness. Lily hoped she wouldn’t get so obsessed with sex like Cass is. The younger sister could barely put up with all the dirty talk and innuendo. Recently it had just got out of hand.

Cass tried to teach Lily how to suck a cock when they were on their school bus by sucking on her finger, but it was just too gross. When Lily finally stopped giggling, she wasn’t very interested so Cass left her, going on a ride with Jack that she said was “for adults only,” when Lily asked to come with. “Learn to suck a cock and maybe he’d give you a ride too”. Lily shuddered at the thought of sucking her own brother’s cock as she had when Cass had said it, but...something about the idea interested her. She’d been feeling funny all day today and when Cass had started talking like that...well, she began to see the appeal.

The house was unnervingly quiet. Usually the sounds of her Mom in the kitchen could be heard over her sunny greeting to the kids. Lately, ever since Lily had heard those weird noises from Mom’s room, her disposition had been a little darker. Hoping for some much needed food, Lily entered tke kitchen and was stunned by the sight of her mother, passed out with nothing but an apron on, her skirt (she had been wearing shorter and shorter skirts lately, with tighter and tighter blouses) draped around her right knee, her blouse undone and hanging from one arm and bra unlatched on the floor.

Jeanne’s legs were spread, her pussy exposed and shining from moisture still leaking down her leg. The sight frightened and disgusted Lily, but something about it also effected her profoundly. She felt warm, slick and funny. Lily began to be concerned her mother would wake up with her here, and she fled to her bedroom. The young girl opened the door as quietly as she could, and closed it behind her with just as much silence. Sitting on the edge of her bed, she silently thought about what she had seen. For some reason, she just couldn’t get the image out of her mind...
