Science Sunday: Do Our Genes Make Us Do It?

Mistress and Slave continue our efforts to find a little privacy as we cope with our newly crowded house.  Sex in the morning, before we hear our little “Divas in training” up and about is one way.  Then yesterday, before Mistress headed to our swim club, and I went to stop by to check out my grandkids, we discovered that our kids had suddenly disappeared.  I was able to coax Mistress into a few moments of worship before she went on her “sun worship” mission.

“Do you mind just sliding my bathing suit aside, Slave…..”

“Of course not, Mistress….”

For once she did not have to suppress those little sounds of delight as I went about my business.

But today’s entry has a higher purpose than simply the play-by-play from here in our re-infested nest. I am reporting on an intriguing summary of recent scientific research that suggests there may be a genetic explanation for a woman’s impulse to cuckold her mate.  In this morning’s NY Times there is an opinion piece (Infidelity Lurks in Our Genes) by science writer Richard Friedman about how genes may pre-determine what he describes as “infidelity”, but presumably also incorporates the contractual right to enjoy the company of an occasional “side dish” that Mistress enjoys.

We have long known that men have a genetic, evolutionary impulse to cheat, because that increases the odds of having more of their offspring in the world.
But now there is intriguing new research showing that some women, too, are biologically inclined to wander, although not for clear evolutionary benefits. Women who carry certain variants of the vasopressin receptor gene are much more likely to engage in “extra pair bonding,” the scientific euphemism for sexual infidelity.
Brendan P. Zietsch, a psychologist at the University of Queensland, Australia, has tried to determine whether some people are just more inclined toward infidelity. In a study of nearly 7,400 Finnish twins and their siblings who had all been in a relationship for at least one year, Dr. Zietsch looked at the link between promiscuity and specific variants of vasopressin and oxytocin receptor genes. Vasopressin is a hormone that has powerful effects on social behaviors like trust, empathy and sexual bonding in humans and other animals. So it makes sense that mutations in the vasopressin receptor gene — which can alter its function — could affect human sexual behavior.

He found that 9.8 percent of men and 6.4 percent of women reported that they had two or more sexual partners in the previous year. His study, published last year in Evolution and Human Behavior, found a significant association between five different variants of the vasopressin gene and infidelity in women only and no relationship between the oxytocin genes and sexual behavior for either sex. That was impressive: Forty percent of the variation in promiscuous behavior in women could be attributed to genes. That is surprising since, as Dr. Zietsch points out, there are so many other factors that are necessary for promiscuous encounters, like circumstance and the availability of a willing and able partner. Although this is the largest and best study on this, it’s not clear why there was no relationship between the vasopressin gene and promiscuous behavior in men.

The article goes onto describe tests conducted on two variations of the vole “family” that may confirm this genetic impulse to stray from the marital bed. It turns out that Montane Voles are prone to have a wandering eye, while Prairie Voles are relatively monogamous. Until the evil scientist begins his experiment:

In the monogamous prairie voles, the vasopressin receptors are close to the brain’s reward center, but in the philandering montane voles, these same receptors are mostly found in the amygdala, a brain region that is critical to processing anxiety and fear.
So mating for the prairie voles activates the pleasurable reward pathway, which reinforces mating and promotes attachment and thus monogamy. For the promiscuous montane voles, sex has little effect on attachment; any vole will do.
It is even possible experimentally to take a home-wrecking montane vole and make him behave like a family-oriented prairie vole. Using a virus as a delivery vehicle to transmit the vasopressin receptor gene, it’s easy to artificially boost the number of vasopressin receptors in the brain’s reward center, and make a male vole behave monogamously. The story for female voles is similar except that it is oxytocin, not vasopressin, that triggers monogamous behavior.

Of course, all of this potential for genetic manipulation has Slave’s imagination running wild:

1)  Could you make a potential spouse undergo a genetic test to calculate the likelihood that they would or would not take up with other lovers during the course of a marriage?
2)   If you feared a spouse was “cheating” could you order up a cocktail of “vasopressin” or “oxytocin” to get them back in line?
3)   And, even more deviously, suppose your wife had her eye on some guy who was married and annoyingly anonymous.  Could you spike his drink with a batch of genetic material that would make him more likely to loose his inhibitions?

All of this also made Slave wonder if there is a genetic explanation for what makes Slave enjoy it when his hot Mistress falls into the arms of another guy.  Do you think male Montane Voles get off when their female mate reports back on her encounter with another male Montane Vole? I guess I should have taken more science classes in college.

Mistress Stops By For Worship

My relatively dreary Thursday at the office had a nice "pick-me-up" mid-afternoon. Mistress dropped by between a lunch meeting and a 4 pm meeting for some "personal attention".

I was in another colleague's office when I received notice of her arrival via text message:

"I'm in your office, slave".

As you might imagine, I found a way to wrap up my "consultation" quickly to perform more important duties.

It was an unusually chilly day here in River City. Mistress had on a leather jacket over her black dress. But she would never let unseasonable weather disrupt her fashion policy of foregoing leg coverings once May arrives.

As a result, all she had to do was slither out of her black undies, spread her legs, and let her Slave get to work. 

I efficiently devoted my tongue and lips to task, leaving Mistress with a cum to tide her over for a while, and my own face smeared with her fragrant juices.

As a memento of the moment, I took this photo - a closeup of those semi-kinky shoes and her well manicured tootsies, which I suspect could be inspiring to at least some of our readers.

Mistress's Walk of Shame

Mistress indulged her slave with some stealthy but gratifying wake-up sex on Tuesday morning. It was particularly generous, since she knew there would be plenty of not so stealthy sex during her planned "nooner" with Jay.

I was at work when she called to say hello on her way to meet her lover. And it was not until around 2:30 pm that she came back onto the radar screen, calling me from her car.

"It was hot, slave.  I think Jay missed me!"

"I'm sure he did after 2 weeks, Mistress."

She told me she was headed to a meeting with a local theatre director - a woman she had worked with in the past. Then heading home. Slave had ridden his bike (excusing me from 'cage time') and it was around 6 pm when I wandered into our bedroom, where Mistress was reclined on our bed, checking her emails.

Soto voco (our daughters were in their rooms) she shared some news.

"You won't believe what I did, Slave...."


"You mean in addition to some hot lunch time sex with your side-dish?"

"Well there was that.... but I mean afterwards.... when I got home after that meeting downtown, I realized I had put my dress on inside out."


She had on a black dress. Right-side out by now. But I was imagining what she looked like with the labels and seams showing. And how dazed and confused after all that fucking she must have been to not notice the difference.

"Didn't that lady you met with notice, Mistress?"

"If she did, she was too embarrassed to mention, slave...."

"So does Jay get demerits for not noticing?"

"Hmmm.... I guess he was a little too unfocused too....."

After we shared a laugh over Mistress's untypical fashion faux pas, we settled onto our bed.  Slave had stripped out of my sweaty cycle ware, and showered. Mistress put down her laptop.

"I'll permit you to worship now, Slave...."

I was more than happy to taste the salty aftermath of her lunch time diversion, before whipping up dinner.

Sex Refugee

It was one of those rare "abstinence days" here at the UCTMW World HQ yesterday, at least for Slave.

Mistress had one of those "way-too-early" Monday morning meetings which made our traditional wake-up sex session impractical.  Then, after a morning of work, we had to rent a truck, drive to our daughter's charming little campus town, and  load up the detritus of a her senior year.

Where do frat boy boyfriends disappear to when it come time to move all that crap out of their girlfriend's off-campus apartment?

Supposedly he had to move his own stuff. Or maybe it was a final round of beer pong?

In any event, by the time we did all that loading and unloading, and returned the truck, then took the kids out to dinner at a local Southwest joint to celebrate "Margarita Monday", we were too burned out for conventional sex.

Of course, Mistress did get some bed time worship to tide her over.

"That was nice, Slave....."

And tasty, I might ad.

But today things are definitely looking up for Mistress.

As we drove north in our rent-a-truck, Mistress was on the phone confirming her date today with her lover, Jay.

"Will 12:30 to 2:30 work, dear?", she asked in that cute little voice she adopts when on the phone with her lover.

It seems that it will. Although it was left unclear who would be picking up lunch. Then again, after nearly two weeks without cuckold sex, maybe their appetites will be for something other than cheese and crackers.

Of course, Jay knew I was listening in as they made their plans.

"Jay says 'hi', Slave....."

"Hi, Jay....."

So at least Mistress will get a chance to vocalize during sex this afternoon, with Jay's house in the burbs acting as a temporary refuge.

Hopefully, Slave will get a chance for some satisfying, if "under the radar" sex, this morning before I head to work.
