Author's Notes:

As promised here is the first chapter of a nine chapter romp base on a prompt from atavares that she would like 'Hey, a mouth is a mouth when your eyes are closed or are busy watching your hot fiance getting licked by a really hot brunette?' to happen, even just as a one shot. I got carried away and end up with a bit of a longer story.

I thought it sounded fun as well, but couldn't see it for where H/C are as a couple in the 'His Little Girl Is All Grown Up' and 'Becoming Us' timeline. So I set this story up as a possible scenario in that universe eight or nine years into it's future. It's not a commitment to that story working out this way at all, but this could happen for our favorite couple in my universe and it made it easy for me to settle into the story having my other works providing a convenient background. You don't have to read either story to read this one. At the end of the day take it for what it is, a naughty bit of smut, with a little DaddyHouse fluff on the side.

I've got all but the final chapter written we are working our way through proofing them now as I put a bow on the story. A huge thanks to atavares and like-waves-on-the-beach for helping me tame the grammar beast and deal with the massive name vs pronoun evil that comes with writing a story with lots of characters and an ever changing POV! I hope to publish one chapter every day or two until done, just to tease you a bit and to give time for the ladies to beta and then I am back to 'Becoming Us' and my neglected unpublished work.

So a few things you should know:

This is set maybe 1 to 3 years from now. House no longer limps. He's had a breakthrough treatment that was developed and tested in 2014 that regrows missing muscle using stem cells and pig bladders. (oh yeah, it is a real thing, and it is so very cool, google it) I don't talk about that in detail, but I mention he had a procedure a couple of times. So as you picture him, toss the cane. His leg will still be scared, but he will have regained a large percentage of his strength and mobility back and will no longer be in constant pain.

Warning:

This story is a heavy MA and there will be lots of sex and sex acts. If you are offended by any of the following, run away now and save yourself:

Graphic depictions of sex

Girl on girl anything and everything

Guy on guy kissing, stroking, and oral as well as suggestion of anal sex

Group sex

Anal play (you know me, the beads are back)

The idea of a 'normal' married couple working as prostitutes with normally monogamous couples as a way to reignite their sex drive.

Having to pack a change of underwear to work because you are too naughty to wait and read this at home (you know who you are)

…

An Indecent Proposal

Neither could believe it had been seven years.

There was a time in his life Greg House would have never admitted that he wanted this life. A life as a husband and a father. A life with Allison. She was sometimes still in shock herself. The gruff man she had fallen in love with was still there on the surface, but the person she had wondered might be underneath, the part she had almost given up on, had been there too: the man who had woken in the middle of the night to tend their children as infants; the man who now sits with them at night to help with their school work, or to give them music lessons at the piano. The man who now loves her so openly and completely.

Everything had changed; changed mostly for the better, but, as with all things, there were changes that both wished hadn't happened.

The changes in their sex life being the biggest of those things. Everyone told them it would happen. They had thought maybe they'd be different somehow. They were so great together, for so long, but the inevitable did happen. They had gotten used to one another; out of sync in their sex drive. On the occasions they found themselves in sync, their attention for one another seemed to be constantly usurped by their children. Greg joked that sex radar was their superpower because, nine times out of ten, an insertion of his penis was quickly followed by a knock on the bedroom door and a needy child on the other side.

As their seventh anniversary approached, Allison began getting a glint in her eye. She had been doing a little research on ways to spice up their love life and, quite by accident, came across something most intriguing. The thought of it excited her, and she was fairly certain it would excite him as well. She wasn't sure if she could really go forward with it, but she also wanted desperately to rekindle the flame they had lost, to come undone with Greg under her—inside of her—like she had done every time their first few years together. Always, without fail, he'd shatter her, push her over the edge and catch her as she fell.

Resolved by the memories, she texted him. 'Got a minute? My office'

'There in 5' He replied. A moment later, he let himself in, closed the door behind him and walked to her desk.

"Desk sex?" he joked as he sat across from her. Hoping that, maybe this time, the answer would be yes. It had been forever since they'd had the work inappropriate dance, having been caught, literally, with their pants down one too many times for Cuddy and the board to continue to look the other way—even with tenure. Yeah, the good old days were just that, good and old.

Smiling at him, she hoped her suggestion would be just as good and just as welcomed by him. Though, she wasn't sure if he'd ever really been serious about the fantasy, now that she fully understood the true depth of his possessiveness of her and her body. Not to mention his deep devotion and commitment with his own body, which in the beginning, she secretly worried wouldn't last given his past appetites for paid sex as a convenient form of release. Over the years, she had become sure he was wholly devoted to her.

"Our anniversary is this weekend."

"I guess that's a no? I was kinda hoping it was an early anniversary present," he thrusted out his lower lip, reminding her so much of James who had mastered that very look nearly out of the womb.

"So, you remember back when I worked for you, we had that couple who had a threesome for their seventh anniversary?" She blurted out, knowing that, with Greg, direct was always the best approach.

"I remember you being pro the every-seven-year threesome. I also remember the wife poisoning the husband, so not sure if I need to be excited or pack up the kids and run."

She let out a nervous laugh. "I think the former. Maybe we can drop the kids off with my brother for the weekend and we can do something different to jump start things again. I thought maybe we just need to make an effort to spice things up a little."

"So, guy or girl?" He asks neutrally, not sure he could share her in that way with a man, but desiring more than anything to please her. It's been so long since either of them had come completely undone, he wasn't sure if either of them could get as hot over each other as they did in the beginning without them stepping up their game. It was normal of any long term sexual relationship, he supposed, even if it was kind of depressing.

"I was kinda thinking both."

"Both?" He asked, curiosity peaked.

"I found this… service. They're real couples who cater to couples, to help them spice things up a bit. It can be a sort of performance art."

"You want us to basicly have a private live porn show?" She raised an eyebrow, tilted her head to the side and bit her lip. She was serious, and his mind reeled for a moment as it set in. A smile overtook his features like a little boy at Christmas. "I might have been wrong about not being able to love you anymore than I already do."

God, he was already incredibly turned on at the idea of it. A little bit of two-way voyeurism could be quite fun. But, wait, she brought up the threesome conversation. Does she want not just a threesome, but a foursome? He thinks to himself, wondering if that too, might be part of the deal. Did she want to watch him fuck another girl? Did she want two men to watch her with another woman? Did she want him to watch her get fucked by another man? He had to know now before he could agree. This wasn't something to leave until in the heat of the moment when they might do something they would later regret.

"So, what are you getting at with the other part then? Reminding me about the threesome conversation? Was that just a reference to the seven year itch or something more?"

"Well, I thought… I mean, I don't want to have sex with another man, if that is what you are getting at. Nor do I want to watch you fuck another woman. I don't think I could handle that. But… they do more than just perform if you want that."

The excitement in his voice was palatable, as he spoke, each scenario that flashed in his brain causing his cadence to quicken. "You want to revisit your experiment in college! God, yes. You have my full permission to let a hot woman lick your entire body, so long as I get to watch. If Other Dude has to be there too, then I guess I can live with that. Because I would like for us to watch them fuck each other and then we can fuck and watch, or they can watch us fuck. In fact, the idea of it is already making me hard, and I didn't think that my dick could work like that anymore. God, the real thing might give me some sort of record-setting erection for a 58 year-old."

Adjusting his package made the point that he was quite serious, so she decided to go in for a pound and continued, suddenly blushing.

"You remember how you used to joke around about the threesome thing all the time, then I told you I'd let a girl go down on me if you let a guy go down on you while I watched and you told me, 'Hey, a mouth is a mouth when your eyes are closed or are busy watching your hot fiance getting licked by a really hot brunette?'" she was thoroughly blushing as the implication sank in fully for him.

He did indeed remember the conversation and smiled at the memory. "Yeah, but you never took me up on the offer."

"Were you serious?" She asked, still avoiding his eyes.

He let out a small, short laugh. "Are you saying you'd like to take me up on that offer now?"

"Yeah, I mean, only if you are really okay with it. I don't want you to do it if you aren't. I think I want to do the other part one way or the other, for you, but… I dunno, I just keep imagining it… and well, it makes me really wet thinking about it." She finally admits, averting her eyes on the last statement.

He was floored. Seeing her like this, shy even, at the request, was completely turning him on. Was I serious? he wondered. They had always pushed the envelope with one another sexually, seeing just how far either would been willing to go together. Always been extremely comfortable and adventurous with sex until a couple of years ago, when life got in the way and turned it into a weekly Saturday morning quicky snuck in while the kids were distracted with cartoons.

Not that he would trade it. He loved the life he had made with her. He was finally really happy. But still, it was a real shame they didn't still fuck like rabbits.

"Allison," he called to her, so she would look him in the eye again and, when she did, he continued "I think turnabout is fair play. Tell you what, I'm willing to try it if you are, and let's both agree that if either of us gets in the moment and we feel uncomfortable about it, we're okay just letting it drop and doing each other. I won't pressure you and you won't pressure me."

She smiled at his deal and nodded an enthusiastic 'yes'. "I'll take care of everything. How do you feel about a masquerade theme?"

Thinking about it for a moment his first instinct felt it was silly, because they knew each other. But he quickly came to the realization he wouldn't ever have to worry about a random run-in with the guy that was going to go down on him at some place like Starbucks and that Allison might have similar concerns. With that, he decided it was a great idea and that it made the whole thing even more provocative.

"I think that sounds hot. We can do the roleplay thing. Like we used to." With that, he stood adjusted himself again and walked over to her to plant a kiss on her cheek, "We should talk more about it later. I'm sure we'll have to set up some ground rules for both sides. Love you. See ya later," and strolled back out of her office.
