Brenda had an obscene view of her father's tight ass, large balls, and long cock as he sawed his cock lazily in four-inch stokes within the tight-lipped sheath of her thirteen-year-old daughter's vagina. Carly's thin white legs, bent sharply at the knees and splayed out to the sides, gave Brenda a view of her daughter she never thought she'd see, as well.

Brenda's first impulse was to rush forward and drag her father off Carly. She could not understand what stopped her, or why she stayed rooted to the spot at the doorway, hiding, though neither could see her even if she were fully inside the room. Perhaps going four months without sex explained her inaction. Perhaps the sight of the largest, most masculine cock she'd ever seen fucking the cutest, most adorable pussy she'd ever seen, short circuited her motherly instincts. Only a flea riding on Tom's balls would have a better view.

The vision was so shocking, yet so erotic, that a primitive part of her brain seemed in control. Her eyes had a direct line to her clit as she followed the obscene in and out motion.

Carly's pleas of, "Please, Grandpa, don't cum in me again," and "Please don't get me pregnant," had no effect on Brenda. If anything those plaintive pleas helped lubricate her panties. Carly added, "Grandpa, I'll suck you. I've been good. I don't wear panties anymore like you want. I let Mom see my pussy. I touched her thigh high up on the inside, very close to her pussy. I'll touch her pussy next time, I swear. Please, don't cum in me."

Brenda's hand went up her dress, slid under the waist band of her panties, her middle finger sliding into the wet grove of her sex, as her father said, "You should have done as you were told. You should have thought of the consequences last night. Now it's too late."

He drove his cock in fully and doubled the length of his stroke. Carly stiffened and cried, "Please, Tom, I can't get pregnant. Give me another chance. I'll finger fuck her till she knocks me away."

Brenda finger fucked her pussy vigorously watching her father going for his climax. He pinned Carly's legs back by pushing against the underside of each thigh, pounding his cock in her cunt as Carly cried and flailed her head. Brenda found herself trying to send him a silent message not to pull out, silently saying, "Don't listen to her, Daddy. Don't pull out. Teach her a lesson. Flood her womb with sperm. She must know she's ovulating; I taught her how to tell."

She then heard, "Tom, don't, I'm ovulating. If you cum in me this time, I will get pregnant. I can't go through that again."

Brenda said inside her head, "Again?" She then smiled and frigged herself harder mentally saying, "Go for it, Daddy. Knock her up again. Don't pull out."

Carly's small hands appeared at her small white ass cheeks. They gripped handfuls of ass flesh and pulled as she begged, "Grandpa, fuck my ass. Please, fuck my asshole. Put your cock in my ass and fuck me hard, as hard as you want. Come in my ass, I'm begging you."

Brenda saw Carly's pink, wrinkled ring blossom and distort with the tremendous pressures being exerted from the pummeling cock. The thick mass moved inside the girl's small body, plowing everything out of its way, then tried to suck everything out as the cudgel retreated. Carly's asshole puckered out on the in- stroke, and sucked in on the out-stroke. To Brenda, a sudden withdrawal of that monster cock would suck the kids guts out with it; still, Brenda kept silently cheering Tom on.

As delightful as watching him fucking her ass would be, Brenda wanted to see sperm leaking from her daughter's fertile pussy. Carly's hands relaxed and dropped just as his buttocks squeezed tense. He pumped sperm into her limp anguished little girl. Brenda leaned against the door frame, humped her fingers, bit her bottom lip, and came with her father.

White frothy fluid bubbled and seeped from the tight seal of cock and cunt. Her father, having deeply deposited his load, paused with the head lodged just inside Carly's pussy. His thickly- veined shaft glistened. The creamy mass gathered at the base of Carly's pussy and began to flow over her anus and down her ass crack. He slowly sank his cock in to the balls, plugging her as he wilted, lying fully on her small body, making her strain to breathe before he rolled them both to put Carly on top.

Brenda sank slowly behind the door frame and listened. She heard her father say, "I don't think the threat of getting you pregnant is motivation enough for you, Carly. I'm beginning to think you want to get pregnant. I'd better see you advancing toward my goal, or I'm going to start letting out some of your pictures."

"Oh, no, Grandpa! No, god, I beg you. I'll do it, I swear. I'm sure she's interested. I can do this. I know I can. I just need more time."

"Your time is running out, Carly. If I don't get my pictures of you and your mother sucking each other's cunts, you're going to pay and pay dearly. As long as I have those doggie shots, you'll take whatever I dish out, and you know I can dish it out. I think your father might like a sample of your portfolio to keep him warm on those cold Turkish nights."

"Grandpa, you wouldn't! You couldn't. I'll kill myself if you do that. I swear, I will. If I do, I'll write the longest suicide letter anyone ever saw. I'll tell them all the things you made me do for your stupid porno collection."

Brenda heard a hard slap and a pained squeal, then, "Bitch! Don't you ever threaten me. You've been threatening that suicide shit for three years, ever since I made you suck off your dog. Well, you're still here, still sucking your dog's cock. He's fucked you more than I have. You aren't going anywhere, and we both know it. You're going to do as I say, when I say, and how I say, until I get all the pictures I want."

Brenda's brain sizzled under a steady flame of arousing images as Carly slowly stopped sobbing. Tom's voice became softer as he said, "You're almost there, kid. Don't fuck up now. All we have left is the mother/daughter series, and the mother/daughter/dog series. After all the cocks you've fucked and cunts you've sucked, after all the vulgar and disgusting shit you've done, I'd think these last two would be a cinch for you."

"Grandpa, she's my own mother. You know pussy makes me gag, especially big hairy grownup pussy. Even that little girl's pussy made me want to retch."

"Carly, you know damn well your mother's pussy isn't big and hairy. Ten to one she shaves or keeps it trim, and you know she keeps it clean like everything else on her."

"I know. I'm sure I'll like her pussy. It's just... she's my mother."

"Carly, she's a woman. I told you, just look at her as another female. She's a hot, sexy little fox that loves attention being paid to her body, and she'll let anyone worship her vaginal shrine. I could fuck her myself, if I'd lick my way up her legs and kiss her fucking ass."

Brenda removed her panties and leaned back resting her shoulders against the wall with her feet widely planted and her skirt pulled up around her waist, listening intently as Carly said, "She's not like that at all. She'll let you fuck her, but she won't respond to crude come-ons. You can't just throw her down and fuck her like you do me. You have to make love to her, softly and gently. She's like a rare flower, and she likes to be treated that way."

Brenda softly said, "Yes, Carly, keep talking to him."

Tom said, "You're probably right, but I can't keep a hardon making love. I want to fuck her, knock her down, pin her ankles behind her ears, and fuck her brains out."

Brenda quietly said, "Oh, god yes, Daddy! Shut up, Carly."

Brenda reached down with both hands and framed her aroused sex as she imagined Carly kneeling before her with those big blue eyes peering up over her mound. Brenda moved her cunt forward and pictured her labia lips flowing over Carly's upturned nose as she gently rubbed her pussy on her daughter's nose from the tip to the bridge. She could feel Carly's soft pink tongue reaching for her hole whenever she brought it within reach. She held that image and heard Carly say, "I can get her into bed. I can eat her pussy, and get her to eat mine. That part will be easy. I just need a little more time to work on her. She liked my shaved pussy. I could see that in her eyes, but she'll freak when I bring the dog in. I know she will."

Brenda began humping and grinding her cunt in the imaginary face, fighting hard not to cry out. Brenda had a new image: Carly on her hands and knees licking her cunt with Skipper, their big black lab, clutching Carly's slender waist while hunching his back and humping his long cock into her daughter's pussy. Brenda strained to hear more.

"Not if you do it just like I told you. Carly, we've been a good team. I've never given you bad direction. You're falling apart on me. I haven't come this far to see everything fall apart at the end. I don't want to be mean to you, and I don't want to ruin your life, but god damnit, I will if you make me."

"All right, Tom. I'll do the dog thing any way you want it done. It won't work, but that won't be my fault. Let me get Mom my way. I now know chicks, and I know my mom. I know both better than you. And stop coming in my pussy. I'm tired of the fucking abortions."

"I am too. This next one, you'll carry to term."

"Oh God!"

"My capstone picture will be you being mounted by Skipper in your ninth month."

"You said these were the last two series."

"They are. This will just be one picture worth a thousand words."

Brenda strained against the wall and bit her lip to silence her orgasm. After a powerful climax tore through every cell in her body, Brenda melted, sliding slowly down the wall to sit, bare- assed on carpet with her knees splayed, staring at the opposite wall and the family portrait thereon, another thousand word picture with her husband centered and Carly before him. Annual family portraits lined the hallway, and Brenda stared at the latest edition. She and the other four kids formed the fringes and background. They even had the family dog in the damn thing.

Brenda could not help but smile when she pictured her husband, Frank, setting up the next family portrait eight months hence, after his return from Turkey. Perhaps she and Carly would change places. Carly's big belly would not be seen standing behind the boys.

Brenda shook her head to clear the image. She heard movement in the master bedroom. Quietly, Brenda turned to get on her knees. She grabbed the panties and crawled to the end of the hall before standing and slipping out of the house.

She saw no reason to return to the office with the computers down for the afternoon, but she had two hours to kill before she could return home at her usual time. She could have simply waited outside for a few minutes before making a loud entrance, but Brenda wanted to give her father every minute alone with Carly she could. She had resisted the idea of taking Carly out of school to sit with her sick father, but he feared having another stroke with no one at home to call for help. Brenda was now sure he never had the first stroke, and Carly was a virtual sex slave to him from eight to four, five days a week.

Brenda realized just how accommodating she'd been. She gave up the master bedroom so he'd have room for his photographic equipment, his hobby. She broke her husband's firm direction not to allow the dog in the house. Her father showed her a magazine article that praised the healing effect pets have on the chronically ill. Skippy became a house pet and they had to live with his embarrassing erections, crotch sniffing, and leg humping. Skippy was relentless in his pursuit of Carly. He would actually jump on her, tackling her. Brenda and the boys had to jump to Carly's aid. Brenda wouldn't even smack Skippy because her father found this upsetting. She had to smile at her gullibility and his cleverness.

Now that Carly couldn't wear panties under her short skirts, the inevitable coupling would surely take place. That was Brenda's first thought when she saw the flash of naked pussy. The flash was intentional, and several more followed over the course of the evening. Brenda interpreted the display as a bold gamble on Carly's part that essentially said, "Mom, you better get that dog back outside where he belongs, or there's going to be trouble."

Everyone knew that Carly was dead set against letting Skippy indoors. The dog was hers, and she should have had the say. She cornered each family member lobbying her cause, but Brenda made the decision. Brenda understood Carly's anxiety. Skippy made her life indoors a constant battle to preserve her dignity and modesty. Her four brothers were no help. They'd jump in to assist their mother, but Brenda knew they never would if she weren't around.

A wicked thought struck Brenda, a thought that sent her finger diving to her cunt. She frigged herself on the highway. Surely there had to be a brother/sister series, a brothers/sister gang bang series that included the dog.

Brenda pounded her pussy at the nasty barrage of images flooding her aroused brain. Her sons' virile naked cocks raping their kid sister, holding her for the dog to mount, posing her for Grandpa's cameras. Brenda ignored the eighteen wheeler that would not let her move ahead or fall back. She stopped trying and kept frigging, thinking about the previous weekend she left them all alone while attending a seminar. Yes, that was the weekend they did the series. She was now certain. She had felt the dirty secret they all shared. She noticed the change in Carly most of all. She did not fight Skippy after that weekend, and her modesty seemed a moot point to her.

She saw the change in her boys as well. They did not get excited or move to rescue Carly from Skippy's assaults. Their eyes did not bug out at Carly's shameless exhibition as she would have expected. They looked, but with the look of familiarity. Brenda knew something big happened in her absence, but she never dreamed anything this big. She climaxed over the images in the brothers/sister/dog series.

Brenda slipped off the freeway and lost the trucker in traffic. She stopped at a shopping mall and wandered the cool mall aimlessly, thinking unthinkable thoughts. There had to be a mother/sons series. There just had to be. What pornographic collection could be complete without one, or a father/daughter series. He'd need that as well, and Frank was out of the question. Why weren't they mentioned?

And then it hit her. Carly wouldn't be needed for either. If her father managed to get a photo of his own daughter having sex with a dog, he'd get his father/daughter series. Brenda looked for a place to masturbate, a rest room, or store with dressing rooms. Her eyes found the Pampered Lady Boutique with the front window filled with sexy lingerie where young boys gathered to gaze upon near-naked manikins or pressed their pimples to the window glass to try and spot customers inside.

Brenda made a direct line for the door and smiled at the grinning boys as she sashayed by with a sexy swing to her hips. Brenda expected a young sexy model in skimpy attire chewing bubble gum to step forward. Instead, a tall, distinguished older man with a pencil-thin mustache emerged from a rack of teddies. He said, "Good afternoon, Madam. I'll just run those boys off, then I'll be right with you."

He started angrily for the door, but Brenda impulsively caught his elbow. He turned with a question in his eyes. She said, "Don't run them off on my account."

He immediately relaxed his facial features as a wry smile formed. He said, almost smiling, "As you wish. Now, how may I help you?"

Brenda boldly said, "I've heard there's such a thing as crotchless panties. Do you sell them here?"

"We sell quite a few, but rarely to a lady as lovely as you."

Brenda coyly blushed and smiled. She said, "I'd like to try some on."

"We have a strict policy that panties can't be tried on without being purchased... for sanitary reasons. In your case, I'll make an exception. I think any woman would be honored to wear panties you had next to your intimate flesh, but found unacceptable."

Brenda's smiling eyes tried to convey her thought: "I'm yours, you silver-tongued devil. Lead on." What she said was, "I will place myself in your capable hands. I want you to pick three pair that you think will best compliment my intimate flesh."

"In that case, I suggest you try them all and permit me to examine the fit."

Brenda smiled and said, "I trust you'll be thorough."

He led her to the rear of the store after grabbing every pair of crotchless panties, three dozen in all. The store was not empty. A few customers browsed the racks with a sexy middle-aged women in skimpy attire following. The woman gave him a look that said, "Nice score."

The bank of three red velvet-padded and mirrored dressing rooms lined the back side wall. They were bright booths with louvered salon doors that blocked the view from knees to chin on most women, unless someone stood close and could peer over the top. He stood close, resting one elbow on the hinge and said, "I think it best that you remove everything except your heels."

Brenda said, "Of course." She then began a slow sexy strip, while facing the man. When she stood naked in her heels, she smiled to return his smile.

He said, "If you would like to walk around the store, you may, but the mall policy requires something be worn top and bottom if customers can see you. A small half-cup strapless bra would serve that purpose. It won't hide your breasts, the bra simply presents them, nipples and all."

"I would like to see how the panties feel walking about. If I must present my breasts, nipples and all, to satisfy the mall, I suppose I must."

"I understand, but I suggest you stay in the back half. We wouldn't want a larger crowd than we already have."

"I'll try to be discrete."

"Please, don't be discrete. If I could, I'd place you in my window as a stiletto heel model wearing only a smile, and the heels, of course."

"You flatter me. I would gladly pose for free, but you would have to tie my hands behind my back to keep me from making a shameless exhibition."

He watched her hands converge on her crotch and her fingers slip inside the wet puffy folds of her sex. He smiled while staring and said, "Yes, I can see. Binding you wouldn't work anyway. Those stiletto heels come from Hong Kong. They'll dissolve in liquid. I'd have to plug you as well."

"I like being plugged."

"I'm sure you do. I'll bind your arms if that would please you."

"That would please me immensely if you are not the gentleman you appear to be."

"I am not, I assure you. You stay right here and keep playing with your cunt while you still can. We're closing the store for an hour. You should have ten minutes alone with your hot pussy, but no more."

Brenda leaned back against the wall, and threw her right foot up to brace against the door frame by his elbow. She peeled back her cunt lips to show him the leak that needed his plug, then entered her wet hole with two fingers of her left hand, fucking herself slow and sexy while keeping her lips open and rubbing her clit with the fingers of her right hand. She said, "Take your time. I'm in no hurry."

He was in a hurry and tore himself away. Less than one minute later, the woman's face appeared looking over the door, looking down at wet busy fingers, then up to say, "You adorable little slut. Don't you dare stop, and don't even think of going anywhere."

Brenda said, "The thought never entered my mind. If you're staying, he couldn't chase me away with a stick."

The woman's face lit up. She pushed through the swinging doors and cried, "Oh, you fucking little bitch!" Then threw herself on her knees and buried her face in Brenda's neglected beaver.

Brenda was surprised by the woman's impulsive assault, but pleasantly so. She ground her cunt on the madly sucking mouth and flailing tongue, mindless of the two female customers looking in through the still open doors. The man was with them and turned to see what startled them. His face went red with anger. When they stormed off, he came running and grabbed the woman by her hair, yanking her to her feet, yelling, "You stupid cunt. What the fuck is wrong with you? Couldn't you wait two god damn minutes."

Brenda brought her leg down and suddenly felt terribly naked. The distraught man addressed Brenda, saying, "They may be getting mall security. You'd better get dressed and leave." He handed her a pair of panties, choosing one at random, saying, "Here, take these. Come back in three days if you still want to play. We have to let this blow over."

Brenda put the panties on and hurriedly dressed. She almost ran from the store, and did run through Ellington's department store to lose the boys. She was still panting when she got to her car, but seconds later, while safely seated behind the wheel, she burst out in nervous laughter. When she calmed, she drew up her skirt and looked at the strange feeling panties she had on.
