Robin felt her heart pound. What she had in mind to do was wild beyond her wildest dreams. Yet, she had to convince her mother of the truth – before it was too late.
She couldn't remember being so close to her mother in ages. Certainly, never this intimate, never undressing her.
She couldn't help drawing in her breath in appreciation when her dress puddled at her mother's feet. Her tits were bare. Her panties were transparent little blue things that didn't hide the deep, shadowy cleft of her ass or the cunning little pout of her pussy-lips.
Robin rolled those down, too. Her mother drew in her breath and opened her mouth as if to say something, but no words came out. She stared at Robin as if looking at her, and yet her eyes focused a long way off – somewhere in time.
Christine was remembering. The other night, on the sofa. While he was fucking her. While he was drilling into her hot, yearning cunt with his big prick.
There'd been something not quite right then – something indefinable, something nebulous. But she'd been so hot she hadn't thought about it. Not until now.
His prick hadn't been quite right. It had been big and stiff and erect. It had entered her cunt and done its job. But it hadn't been steely-hard.
Not until the last, just before he'd come inside her and flooded her juicy cunt with his sperm. Not until the moment when she'd opened her eyes very slightly and had looked at him through the narrow slits.
She'd seen him. He'd been looking off to the side. If she hadn't been so hot, she would have wondered why, but that, too, had escaped her notice. Until now.
There was a quality about a prick when it was fucking you. She'd learned that with Carl. There were times when his cock seemed like a bar of tempered steel – so utterly hard it would have shattered if she'd tried to bend it.
There were other times when it was more like a bar of lead – so pliable that it was ready to go soft with the heat of her pussy rather than harder still.
Those were the times when she knew he was preoccupied, when his heart hadn't really been in the fucking he was giving her.
Logan's prick had been like that the other night. At first. All the while he was reaming her. Until the last, when he'd been looking off to the side.
Then, his cock had hardened and swelled inside her cunt and bucked wildly as it spat and spewed. She'd wondered why at the time. So fleeting had been the impression that she'd forgotten it. Until now…
She turned her head slowly and oddly. She looked at her daughter. She opened her mouth again. "The guest house?" she croaked hollowly.
"It's the truth, Mom. Pete watched. He can tell you it's true. I thought he'd come in to fuck me. Here, Mom – get up on the bed like this, and I'll show you what really happened."
Christine was pliable. All Robin had to do was position her mother, and it was done. She rested on her elbows and knees, her naked, sweet ass sticking up and back.
"Your picture…" Christine whispered. "That was what he was looking at. That was the only thing he could have been looking at. Then his cock went hard. All the while he fucked me, it was… it was… you! Your picture! Oh, my God!"
Whether it was because Robin had snapped her fingers at Midnight to get him to leap up on the bed behind her mother's upthrust ass or whether it was because she'd finally fitted the loose pieces together in her mind, Christine's eyes came back into focus.
She lifted her head. She looked straight forward and saw the pink, open maw of her daughter's pussy as Robin knelt in front of her and held her shoulders down firmly with her young weight.
"No!" she cried. "I can't believe it! I just can't believe it's true!"
Robin didn't respond. She wasn't sure what her mother was talking about, but she could guess. She shifted her position, stretching her legs out on either side of her mother's body, bringing more strength and weight to bear.
"Robin, what are you doing? Let me up. Why do you have me this way? Why are you trying to hold me down?"
"Because I'm going to show you, Mother – just what I learned to do from Logan. Up, boy!" she commanded, snapping her fingers again.
Midnight didn't even pause to sniff at the pocket of pussy-meat flaring back at him from between Christine's open thighs. After being scolded a moment ago, he was willing to be the most obedient dog there was anywhere.
He fairly leapt up over Christine's naked ass, standing on his hind paws between her parted legs and wrapping his front paws around her slim waist.
He pulled himself up against her round, tight butt with a quick lunge, his prick already scarlet and thrusting from its sheath, hard and darting and slippery.
The pointed tip shot forth again and again, stabbing and spearing from under his black belly, a brilliant red lance that gleamed and throbbed alarmingly.
"Ohhhhhh, my God!" Christine cried, her head stretching from her neck, her spine arching. "Get down! Midnight, get off my ass! Ohhhhh, what are you trying to do to me, Robin!"
She struggled wildly for a moment, heaving her shoulders against her daughter's strong grip. She tried to fling her ass around to get from under the hot, furry blanket of Midnight's belly, but the big dog held her ass with surprising strength.
He hunched closer and closer. The tip of his prick now stabbed against Christine's thigh, then slid between them, then poked into the deep crack of her ass.
"Yaaaaaah! Make him stop!"
"He did it to me, Mommy!" Robin cried, gritting her teeth as she held strongly onto her mother's bucking form. "Logan made him fuck my pussy and then made me suck his cock off. That's how great a guy he is, Mommy. That's how much better for you he is than Pete is for me!"
"No! No, you're lying! He'd never do a thing like that! God, let me up! Ohhhhh, his prick is hot! It's right – OH, MY GOD, ROBIN!"
Christine's eyes bulged from her head. The cords stood out on her neck as she tried to stretch her whole body forward away from the probing stabs of Midnight's cock. She nearly pitched Robin onto her back with the sudden lunge.
"Don't worry, Mother. It doesn't hurt. In fact, it feels pretty good to get fucked by a dog! It's better than not getting fucked at all, Mommy. Just think of all the hot times you've missed in the last three years. Isn't it a shame Logan couldn't have shown me how to get Midnight to fuck us three years ago, Mommy?"
"Ahhhhhh!" Christine shouted, shaking her tight ass. "Hot! So hot! His cock's so hot! It's in my pussy! Robin, he's fucking me! Ohhhhhh, my God!"
"Don't cry, Mommy. Don't think of what Daddy would think if he knew. Daddy's dead. He can't know. What matters is what Logan would think if he could see you now."
"Oh, God! Oh, God!" Christine cried, her body pitching back and forth under the powerful thrusts of Midnight's body.
"I'll tell you what he would think, Mommy. I know. He'd think it was neat. He'd think you were a real kinky bitch. He'd love it. He'd ram his prick down your throat while he watched you getting fucked. That's what he'd think, Mommy!"
"Noooooo!" Christine moaned raggedly, shaking her head, her tits dangling from her chest, her hair hanging around her face and brushing silkily over her daughter's spread thighs.
"How is it, Mommy? Midnight's a pretty good fucker, isn't he? Can you feel his knot? Can you feel how his prick swelled up inside your pussy and made everything so tight he can hardly fuck his hot, throbbing prick back and forth inside you? See? I know what it feels like, don't I?"
"You… Ohhhh, how long have you…"
"I told you the truth, Mommy. Since yesterday, that's all. I can't help it if Midnight learns fast. But he sure learned well, didn't he? You must think so, too, Mommy, because your tits are all hard, and your nipples are red and spiked."
It was true! Christine felt the firmness of her tits as they jiggled back and forth under her chest. She felt the wetness growing inside her pussy as well and the way her cunt muscles were beginning to squeeze around the dog's mighty shaft.
