The Alice Experiment, controlled by you

December 12, 2025 Mr. X Leave a comment

Several days ago I got an e-mail from a reader named [Alice]:

Your stories are incredibly sexy. I found out about this website when I was sitting at a cafe near my university. A cute little indie girl (large glasses, pixie haircut, a macro-dermal piercing on her cheek) had your website pulled up on her laptop. Now I know it is kind of weird to look at someone’s computer, but when an irresistibly cute girl is smiling and shivering…you kind of want to look. Sadly, I haven’t seen her again, but oh well. I have thoroughly enjoyed your stories, and whenever I read them I end up picturing that indie girl in them. I’m a bit jealous of Lisa for having ‘assignments’!

The Result, The Sex Experiment

Sex with strangers: the result of The Business Card Experiment

December 10, 2025 Mr. X Leave a comment

I heard my wife come in. I even heard the zip of her dress as her clothes fell to the floor. I was listening closely. I knew she had come in from my fantasy.

I sat for a while in my office, listening through the silence. Then she began to moan. I listened to her moaning to the unknown images that flickered through her mind, and I was instantly hard: both because my wife was in the living room naked and masturbating, and because the images were unknown. Sex with strangers? What had she gotten up to today? What man had put her in such a state? I wanted to know everything, and I wanted to know nothing at all. What I really wanted was to take her in wordless passion and see the unknown fantasies flit across her face. Continue reading Sex with strangers: the result of The Business Card Experiment →

Shopping for Sex: her response to The Business Card Experiment

December 8, 2025 Mr. X 22 Comments

Well you’re certainly getting creative! It’s always the little twist to your dares that makes them difficult (as I’m sure you know). I give my business card out to strangers every day (and now I’m worried/excited to think that I’ve given one to you at some point), but handing it over without explanation was another matter entirely. Not that it wasn’t terribly exciting! The first step, however, was to find some stranger hot enough to entrust with my cute little card (as well as the rest of cute little me!). I had lots of errands to run all over the place today, and as I did I was more aware of other people than I’ve been in a long time. It made me excited to assess their bodies so closely, and then to assess my own body for its reactions to the assessments. There was a lot of assessing going on out there! And my nipples were tingling and taut with the excitement of it all (showing clearly through my dress, I’m sure, so that I felt nearly as naked as I did during your first test).

The Business Card Experiment

Dear Mrs. Fantasy,

I can’t stop thinking about your orgy fantasy. As I walk down the street, every woman is you, and I let my eyes run over their breasts, their hips, their legs…. I pretend you’re naked before me, and then I slip into your orgy fantasy: your eyes are fixed with lust on your husband’s cock, and on the heaving breasts all around us, and I am behind you with some other man, having shed my clothes. My body is pressing up against yours, and you feel my cock tracing a line across the small of your back, then across your firm ass as it arches up towards me, and then my dick slips down between your legs, and although you do not know who it is behind you – you reach back to place a hand on my chest but do not turn to investigate further – we’re both too far gone to do anything but fuck, and fuck, and let our bodies be drawn down towards the floor as others watch with lust and envy.

Fucking the teacher: a reader responds to her experiment

December 3, 2025 Mr. X 9 Comments

Several days ago I received a sexy e-mail from a fearless reader. We hit it off, both got horny in the process, and then she asked if I would give her an experiment of her own. I was happy to oblige, and now she’s written back. And I’m more intrigued than ever. She does know what I like. First she thrilled me with a description of her naked body. I’m going to keep that to myself for the moment, but to set the scene: she’s in her twenties, exotic looking (and obviously very attractive), with full breasts, taut skin and lips that are (I’m paraphrasing here) made for blowjobs. Is it any wonder I’ve been distracted lately? So, without further ado, here’s her fantasy, and how she responded to the experiment: Continue reading Fucking the teacher: a reader responds to her experiment →

Fantasy Experiment, Readers, The Sex Experiment

A sexy e-mail (and A Reader Experiment)

December 1, 2025 Mr. X Leave a comment

The other day I got a sexy e-mail from a reader named Lisa, and I most definitely have a new obsession (can you have too many?). Here’s her (sexy) e-mail:

To Mr. X,

Your stories excite me beyond the point of orgasm. I’m incredibly intrigued by your life, your anonymous persona, and your wife the sex kitten. Reading the posts alone make me as wet as Mr. X makes your wife. I cannot explain how horny everything makes me. I love the fact that you share this with the internet community. I hope you’re able to continue this experiment for a long time. I also hope you start making your wife take pictures of her sexcapades and share them with us….

Thank you for making me horny,

Lisa

Private orgy: the result of the Sex Fantasy Experiment

November 28, 2025 Mr. X 2 Comments

My wife still had Mona’s cell phone when she came home that evening from rendezvous to reveal her sexual fantasy. I had no idea how the meeting had gone, or even whom she’d met, because she hadn’t yet written to Mr. X. I’d been checking my e-mail every minute, of course, glued to my computer, so over dinner when she said she had to run over to Mona’s house because she’d left her cell phone behind after their coffee date that afternoon, I knew: 1) she’d made the right choice of friend to confide in; 2) she’d likely revealed a sexual fantasy hot enough to distract the otherwise seen-it-all Mona; and, well, 3) I couldn’t help but think about Mona’s tits (she’s the sort of woman that calls up an immediate image). Now that I’ve read her response, I can’t stop thinking about them, except that now my cock is firmly placed between the two. I can’t imagine my wife ever bringing a friend into our bed for a threesome, but if she did, Mona would be near the top of my list.

A café orgy: her response to The Sex Fantasy Experiment

Dear Mr. X,

This challenge actually turned out to be harder than the last one (but then you probably knew that). Letting my tits pop out of my robe for the delivery man somehow just seemed like a game, but there was no wiggle room on this one (and you know I do like to wiggle!). I know my sexual fantasies, of course (long erotic books could be written with dirty illustrations, like a modern day Kama Sutra starring yours truly), but I spent hours nervously debating which of my friends wouldn’t be too shocked by just how slutty I’ve become. Then I thought, screw it, and I called up a friend who I’ll call Mona. She’s a good time girl, cruising through her second divorce, and I figured that she could at least giggle about it with me.

The Sex Fantasy Experiment

November 24, 2025 Mr. X Leave a comment

Dear Little Exhibitionist,

How I would have liked to see you taunting your delivery boy. I can imagine that he’s still masturbating to the memories of the sight of you, and the extended sex fantasy the memories must inspire. I know I still am. I’ve promised to remain anonymous, and I will remain anonymous, but how I would have loved to run my hand up the inside of your soft thigh as you wore that little robe of yours. I would have loved to watch your husband pulling it from you, too full of desire to be shocked by your audacity anymore, and then to have watched him take you towards explosions with his tongue. And maybe you would have glanced across the room and seen me (the bastard) standing there, but you wouldn’t have said anything. You would have shut your eyes and groaned with your own pleasure, and the pleasure of what you were doing to us both. But enough of that…. Continue reading The Sex Fantasy Experiment →

Fortune cookie erotica: the result of The Delivery Man Experiment

November 21, 2025 Mr. X Leave a comment

So my wife has turned out to be an exhibitionist, and I’ve turned out to really like it. I’ve always liked the looks she gets from men when we’re out together – they undress her with their eyes, just as I occasionally do to their girlfriends or wives. The thrill is in imagining crossing the borders we place around our lives, but my goal is to set new borders for us out at the far edge of imagination, and watching my hot wife reveal herself to a stranger was out there in the realm of pure erotica. The problem is that the border is always shifting, and now I want more! Continue reading Fortune cookie erotica: the result of The Delivery Man Experiment →
