There's not really anyone in my life I feel like I can share this with, and I wanted to write it down so I remember the details.

A while back I [M38] came across a series of videos. They were of a couple that does porn together, and they had a sex doll. They were setting up classic MFF threesome positions. Guy fucking the doll in missionary while his girlfriend sat on the doll's face. Guy fucking the doll doggy style while the dolls face was in the girl's crotch. Doing some ATM from the doll's ass to his girlfriend's mouth.

At one point they did the 'stack' of two girls on top of each other, both of them available for taking from behind. This particular one got me. It looked hot, the girl's ass looked a lot like my wife's [F33], and it got me thinking. After talking it over with the wife, and many weeks of research online, we finally bought a sex doll.

It was delivered over the holidays, so finding a time to be alone and without the kids was a challenge. I managed to find some time to test the doll alone, and it was as good as I hoped. It looked and felt great, the only real hindrance is the cleanup is a bit of a time investment.

The night we got it, we took at look at it together. Even though we didn't have time to fully explore, just watching my wife grab the doll's breasts, or slide a finger between the doll's legs had us both turned on.

But finally we had a night with the kids at their grandparents. We didn't explicitly state it, but it was left unsaid that tonight we would explore the doll together.

My wife has always been vanilla, but always extremely willing to explore the ideas and fantasies I've brought up . I knew tonight was crossing into new territory, so I decided to take things slow.

We started making out before even opening the storage crate with the doll. The lights were set to a dim blue, relaxing music was on the background. My hands started roaming her body as we kissed, unable to keep them to myself. We were both fully clothed and just standing in the room, but I quickly slid my hand into the back of her pants, pulling and squeezing her large ass. My other hand slipped under her shirt and started teasing her nipples. Flicking and pulling on them, switching from one to the other.

My wife was starting to get worked up, and still standing I lowered my head to take a nipple in my mouth. This made her gasp, and reach hungrily into my pants. I was already hard as she wrapped her fingers around me and started to frantically slide up and down.

After a few more minutes of us getting each other worked up, my wife broke off the kiss with a breathless voice and asked if we should 'bring her out'.

I was more nervous than I expected as we opened the box and I lifted the surprisingly doll out. My voice sounded calm to my ears, but my hands were trembling as I showed my wife how to put it together, how to put the wig on, etc.

My wife was intrigued, curiously cupping the doll's breasts. "She's cold," she said, and I don't know why but it thrilled me to hear her refer to the doll as 'she'. My wife said she'd warm the doll up and took her shirt off and lay on top of it after feeling it's skin temperature. She pressed her breasts against the doll's, sliding her body side to side.

After a brief time we checked the doll's skin, which was warmer but still cool. My wife at the time was on her period, so tonight wasn't intended to be a full 'threesome' kind of experience. But she was curious to see me and 'her' together.

She suggested I get on the doll and try to warm it up a bit more. Nervous again I took off the rest of my clothes and kneeled over the doll. My wife put some lube on her hand and used it to cover my cock, sliding her hand up and down. She used her hand to guide me into the doll.

At first she just watched as I started to slide myself in and out of the doll. My wife was a bit mesmerized as I started to move faster. "Your hips," she said. "I've felt them pushing into me, but I've never seen them." She started rubbing my ass with her lube covered hand. "It's primal." She paused a moment, and said "I've still got this all over my hand. I could just do....this."

She slide her hand between my butt cheeks, one slippery finger started probing at my asshole. I slowed down enough to let her find what she was looking for, and let out a gasp of my own as her finger slid inside me. If you know, you know.

Thrusting and timing it with my wife became awkward, until I told her to guide me by pushing. Suddenly, her hand was on and in my ass, pushing me, making me thrust into a very attractively built sex doll. My wife was fingering my ass and making me fuck. It was one of the hottest things I've ever experienced.

I had intended to draw things out, and try a few different positions but I lost all control. I started thrusting faster and faster, gasping and moaning. My wife's breath started increasing too, with a breathless whisper of 'Are you going to cum in her?'

That sent me over the edge and I thrust deep, my muscles clenching and convulsing around the finger inside of me as I had an incredible orgasm inside the doll.

"Clean up later," my wife said, guiding my hand into her pants. She was as wet as I had ever felt. It took some very energetic action on my part, as I pumped two fingers in and out of her while I pressed and circled the palm of my hand on her clit. The harder it takes to get her to the edge, the bigger the orgasm and her legs trembled and clenched on my hand as hers crashed over her.

Once we had both settled and cleaned ourselves up a bit, I started instructing her on the cleaning and maintenance of the doll. I mentioned how there is a big set up and clean up overhead, and it almost makes you want to use the doll more than once in between pulling her out and putting her away. My wife said I was more than welcome to if I was up to it. She said she'll just 'read her book' while I did what I wished. 'Read her book' is literal, but is often a coded phrase to me I can free use her (while she pretends to ignore me), or other innuendo.

In this case she was going to read a smutty book and sit nearby. However as soon as I got in position again her eyes went back to my hips, where my crotch was entangled with the doll. I was hard once more and started fucking the doll. As soon as I did, her hand went into her pants and she started playing with herself.

While we have explored mutual masturbation before, we had never done anything like this. I was fucking the doll with everything I had, while two feet away I could see my wife's hand flying up and down furiously, her eyes locked on my hips where they thrust in and out of the doll. After a few minutes she came again, and that was enough to get me over the edge as well.

That was just our first, 'quick' experimentation. We're hoping to send the kids off to their grandparents this weekend, and have a full evening together, just the three of us.

I've always wanted a MFF, and if my wife ever comes around to the idea (she's curious, but uncertain) I think I will have to credit it to this doll, which has already given us one of our more memorable evenings together.
