"I'll bet Dad never did that to you, did he," Becky said, beaming approval as her Great Dane took a few tentative laps into the dilated vestibule of her mother's vintage snatch.
"He t-tried but… I would never let him," Eunice gasped, her eyes growing larger and larger with disbelief as the full impact of the dog scratchy tongue sent flaming arrows of perverted pleasure shooting through her loins. "Ohh, ohh… how can something so filthy… feel so g-good?"
"It is lovely, isn't it?" Becky chuckled with lewd delight. "But don't flip out yet, Mom, the best is still to come! Up, Buster! Into the saddle, boy, it's time to ride!"
Becky grasped the dog's collar, tugging upward as she reached back and took hold of his secretion-dripping, fully-erected penis.
"Woof, Woof!" Buster barked, rearing up on his hind legs. His forelegs pawed the air in a horselike manner as he hopped forward on his hind paws, allowing his mistress to use his peter like a handle as she pulled him into position.
"Oh, my stars!" Eunice whined, cringing fearfully as the fawn-colored form loomed above her. She clenched shut her eyes as the glossy-coated beast descended, his weight rocking the bed when he planted his forepaws into the mattress just below her shaven armpits.
"Relax, Mom. Buster won't hurt you. He might drool on you a little bit when he gets going good, but I doubt if you'll even notice it by then."
Eunice tried to take Becky's advice. But she was too terrified to relax, and too hot to back out. Fearing that this would be the end of her, the fallen widow lay there docilely with her eyes clenched shut and the hands of her outflung arms made into fists. She was shivering with a paralyzing mixture of fright and desire, feeling for all the world as if she was about to be sacrificed to some obscene, horned God of bestial lust.
Then she felt the forefront of her daughter's hand snuggling up to the hair-fringed flanges of het blood-engorged labia majora. She whimpered piteously and bit down on her lower lip.
"Get ready, Mom!"
Eunice steeled herself for the unnatural join of their human and animal genitals. A mental image of the Great Dane's phallus flashed before her, causing her to shudder reflexively. It was long, broad at the base and tapering down to about the size of a pencil eraser at the front, that reminded her of a ring sizer she'd once seen in jewelry shop. Only it was red, not metallic-colored, inflamed and angry-looking. The very thought of that wicked thing penetrating her struck new fear in her palpitating heart, and yet she could hardly wait to feel it thrusting into the burning, itching slot between her shaking, wantonly parted legs.
The tip of it touched the tiny opening of her crimson inner labia. Eunice sucked in her breath and turned her head to the side. She held her lungs full of air, her heart hammering wildly against her rib-cage, as her daughter's hand guided the pointed head of the animal's huge erection through cringing portal of her labia minora and into the lower region of her yearning vagina beyond.
"Ooohh… ooohhh!" Eunice sighed, letting her lungs deflate slowly as the tormenting itch of her insane arousal made her squirm about in sensual discomfort.
"Now, boy!" Becky yelled, and suddenly her hand was gone.
Just as suddenly the huge dog hunched forward, emitting an amazingly human-sounding grunt, and skewered the awesome length of his throbbing red cock full into Eunice with one powerful arch of his back.
"Nnnaaarrrhhh!!" she screamed, and then sucked in her breath raggedly as her body began quaking helplessly from the mixture of pain and pleasure which the deft impalement sent washing over her.
A pair of fuzzy nuts hit her in the ass. The dog's underbelly smacked down over her trembling abdomen. She'd never been so full of pulsating prick in all her life. The base of Buster's organ was at least as big around as the average man's, and because of its length – seven inches or more – the pointed head had rammed into the tender neck of her pear-shaped uterus and shoved the most feminine of all her female organs a good two inches higher into her abdominal cavity. The hairy mouth of her sex hole was forced open as it hadn't been for more than three long years, and the elastic walls of her inner sheath were stretched by the upward displacement of her womb during the lengthening of her vagina to accommodate the final inches of the tapering ramrod which had reamed her to size.
It hurt to have so much hard meat rammed up her so swiftly, but it was a good hurt. A damn good hurt! Huffing to catch her breath – the rough penetration had literally knocked the wind out of her lungs – Eunice thrashed about like a rabbit that'd been run through with a sharp stick while Buster settled down onto her and clasped her torso with his forelegs, getting himself into position for the long ride ahead.
"Well, Mom, what do you think of this stud hound now?" Becky cackled with glee.
"Who the hell… ooohhh… can think at a… mmmm… time like thisss?!!" Eunice hissed, gritting her teeth and batting her eyelids as the Great Dane began stroking it to her in an unhurried, almost lazy manner.
"Yeah, I thought you'd like it once he got going. You do, too, don't you?"
"Yes, yes!" Eunice admitted. "I can't… aaahh… help but like it! Oh,shit… ooohhhh… fuck me, you beautiful beast! Nnnn, God, that's good! Oh ohh! Just what… aaahh… I… neededdd!!!"
"Do my ears deceive me?" Becky asked with giggle. "Is that MY mother I hear talking dirty? Out of all the times I listened through the wall, I never heard you say anything like that while Dad was balling you! You must really be hot!"
"I m-must be crazy!" Eunice wailed, beginning to grind her well-padded posterior in a jerky circular motion as the increasing pleasure of the dog's red pecker shuttling within her pulsing pussy made it impossible for her to lie still a second longer. "But, Lord, forgive me, I… just… don't… caarreee!!!"
"It's good to hear you testify, Sister Murphy," Becky chuckled with lewd amusement, as if they were in church, but the pained expression which her mocking remark brought to her mother's face wiped the silly grin off Becky's. "I'm sorry, Mom. I shouldn't have said that. I'll shut up now and let you enjoy your fucking. Just relax, dear, and let it all hang out. You've got a climax coming that you wouldn't believe right now. You'll thank me when this is over, wait and see."
Becky lit a cigarette and climbed onto the head of the bed in a cross-legged sitting position. She leaned back against the headboard and made herself comfortable. From experience she knew that Buster was just getting warmed up. He'd shot his first load fairly quick because she hadn't given him a workout in about a month. But he was working on his second cum now, and that would take considerably longer. She smiled to herself. Her mother was in for a good long ride. At least ten minutes. Once Buster started humping away, there was no stopping him until he shot off.
"You're going to get some of that fat bottom fucked off of you, Mom," Becky said under her breath. "It'll do you a world of good, too. Maybe you won't be so uptight after this."
Widow Murphy didn't appear particularly uptight now. Beads of perspiration were beginning to pop out on her plump torso. She was breathing rather hard. Her toes and the balls of her feet pushed down at the carpeted floor. It was getting good to her. She was trying to work with the huge dog, as she'd seen her more experienced daughter doing, but Eunice's upward lunges were jerky and uneven whereas Becky's had been smooth and rhythmic. The fatty undersurfaces of her fleshy thighs hung down somewhat, swaying and quivering as she strained to hump her pleasured puss up to the steadily thrusting Great Dane.
"Ohh, good… good… it feels… soo goooddd!!!" she panted, timidly stroking the powerful shoulders of the regal animal above her.
Now that his forelegs were locked beneath her sides, most of Buster's underside was in contact with her body and she was supporting perhaps half of his 150 pounds. The firm pressure of his gently rocking form was pleasant to her in her current condition of mind-fogging passion. She especially liked the feel of his warm, furry body rubbing against the moist surface of her creamy-textured human skin. It was so different from the feel of her deceased husband, who'd always supported his weight on his knees and elbows at her request, because too much bodily contact when they were having intercourse had made her feel as if she were being smothered.
