**Author's Note: So this is clearly my first foray into a story exploring this particular kink, so, go easy, but feedback is appreciated!
Dave was frozen in shock, his hand still holding the door knob to the bedroom he shared with his wife, Chrissy.
They had been married for almost 2 years now; and Dave was still awed that she had chosen him. He wasn't exactly the most attractive man; he was tall, so at least he had that going for him; a whopping 6'3" was usually enough to get him at least a few dates. His brown eyes were covered by glasses, he was on the scrawny side, and his personality was definitely nerdy. He liked his video games, his numbers, and his Star Wars. And Dave was man enough to admit that his cock wasn't very, well, man enough. It was a little smaller than average, and not very thick. But he liked to think he made up for it in other ways; using his fingers and tongue more often than not. And he knew he made his wife come, so at least there was that.
His wife Chrissy, on the other hand, was a hard 10. Absolutely. She was about 5'6", and had long, blonde beautiful hair. Her icy blue eyes were piercing, and if you weren't drawn to those first, you were drawn to her big, perky breasts; they were 34DDD, and so sensitive. Dave could play with his wife's tits for hours, and had before. The rest of her body was pretty perfect as well; slim stomach, well-toned ass, great thighs. She kept her pussy waxed, and it was always so wet for him by the time they were really getting down to business. His wife had such easy triggers. Some heavy making out, some rough nipple play, a neck filled with erogenous zones. And then there were her feet; Dave loved his wife's feet. So dainty, and arched, and she always had her toes painted because she knew how much Dave loved her feet. He loved sucking on her toes, licking the heels, rubbing his dick against her feet. He even would paint her toenails for her.
Chrissy could have any guy she wanted, and she had chosen Dave; and Dave tried to never let her regret it. His wife had gotten progressively more kinky as their relationship and marriage grew, and Dave tried to accommodate her every desire, so she wouldn't be tempted to look elsewhere. When she wanted to add toys- dildos and vibrators for her and cock rings for him - he was game. When she wanted to play strangers in a bar with him and fuck in a relatively public place, he was hesitant but eventually willing. And when Chrissy wanted to use her dildos on him - she was kind enough to start off with the smaller ones - he agreed to try it once, and didn't hate it, like he thought he would, and wound up doing it a few more times. He even came from it.
But there had been a recent fantasy of hers that made Dave particularly uneasy. It was a fantasy that as a man, he shouldn't be drawn to. It was demeaning, emasculating, a little humiliating. And what made him particularly uneasy was how appealing this idea did actually sound.
She had shared her fantasy of cuckolding him.
"Now, Dave, I would never do it," she had assured him, "unless we talked the hell out of it. Pros, cons, looking at it from every angle. I don't want you having any regrets, or feeling like I'm not totally happy with you. But... don't you think it would be just a little hot to come home from a long day at the office, not finding me anywhere until you came into the bedroom? And there I'd be, bent over our bed with some other guy fucking me? Is that at all appealing?"
Dave had squirmed a little, unsure of why the idea was a little thrilling. "I don't know, babe... I mean, it could be, but... I don't... What if you like his dick better than mine? You know I'm n-not particularly, well, g-gifted in that area-"
Chrissy had put her finger to his lips to stop his stammering. "I love YOU, Dave, that would never change. And I'm not asking you to do it, baby, just maybe... explore the fantasy with me? We can take it slow, see how you feel about it after every step."
So Dave had agreed to keep an open mind; he didn't think he had to worry about it for a while. She had so many other fantasies and kinks she wanted to explore. She wanted to do something more in public, she wanted to buy him panties, she wanted all sorts of things. So surely this fantasy would take a place in line closer to the end.
Turns out, though, he had been wrong.
The sight that greeted him when he had opened the door to his bedroom, after a long, hard day at work, was jarring; and yet so fucking hot, Dave's cock was already hardening in his pants.
His wife was spread eagled on the bed, completely naked. She had one hand mauling her breast; Chrissy enjoyed the rougher treatment on her breasts; pulling and pinching her nipples instead of rubbing, twisting instead of licking, gently nibbling instead of sucking.
And the other hand was fucking a large dildo in and out of her cunt. She was so wet, he could hear it; that juicy slide in and out of her wet tight cunt. Her hips were fucking that dildo, and her mouth was open on a silent moan, her head arching a little as she slammed the dildo harder into her pussy. It was a huge dildo, too; it had to be at least 8 or 9 inches, and looked to be stretching her tight box.
Dave finally made a noise; it probably sounded like a strangled moan. Chrissy's eyes opened slowly, and she looked over at her husband. Licking her lips, she gave him a sultry smile as her eyelids fluttered, trying to stay open as she drove the dildo into a spot that seemed to just rub her right. "Hi, baby," she greeted breathlessly. She arched as she drove the dildo into her twat with a little extra force, moaning loudly.
"Wh-what... what are you doing?" he sputtered, his cock already so hard he could hammer nails with it.
"What's it look like I'm doing, baby?" she crooned. "I'm getting fucked." She reached for something to the side of her - Dave saw that it was another dildo, a little smaller than the thick, long one in her cunt, and she stuffed it in her mouth and worked the toy in her pussy faster as she moaned and gobbled on the other. She slid it in and out of her mouth, licking up and down the sides, before shoving it down her throat and purposefully gagging on it. She pulled it back out of her mouth and Dave watched as she licked it clean of her spit.
"It... It seems awfully big, don't you think?" Dave responded. His own small cock was twitching in his pants, looking at the lewd display his wife was presenting him with; the big fake cock was spreading her twat open, and it was getting deep, places Dave had never been able to reach himself.
Dave had to rub a hand over his crotch at the thought. His wife hadn't had anything but his cock for years - two years of marriage, a year and a half of dating - but it seemed like her pussy wasn't having any trouble with the bigger toy.
"Yes, it is awfully big," she moaned as she pushed it in as deep as it would go before bringing it back out and fucking it back up into her again. "It feels so good, baby," she looked Dave in the eyes as she said it. "Take out your cock, Dave," she commanded.
