Curious.. I could have written that post.  So I am very interested in the answer.  I would add that the experience in no way makes me question my masculinity, or heterosexual-ness (is that a word?).  But it is all in the opening of experiences and broadening my horizons.  

I would do it in a heartbeat for her.  We have talked about it and I know it will happen when she dictates it...

No snide remarks here whatsoever, adambede,

Just mull around the idea for a while...could you really do it? My bet is that the phantasy is way more powerful than the reality...but only you will know..and the only way you'll REALLY know is to set up the situation. It's not that bizarre as a scenario. For whatever reason, you find being dominated by this provider a total turn-on, no matter what she asks you. Or..???

Before you go further, why don't you have a long chat with yourself and ask what you'd be willing to do for this provider in general? What if she asked you to jump off a bridge or a building? Lend her 10,000 dollars? Is it only sexual/sensual requests that turn you on?

As to the prevalence of these types of phantasies, well, domination has been common throughout the ages and throughout civilizations. A good dominatrix can almost hypnotize her client. There are all sorts of fetishes and situations...everything from wearing baby clothes and diapers to getting mummified. Is it sexual? Well, to submissives, it clearly is. Sucking someone's cock seems one of the more reg'lar fetishes, but heck, I'm a gay-affirmative woman, so to me, that seems one of the most normal things to do in this world.

Now, I just have one caveat - if you do decide to go through with this phantasy, PLEASE use a condom and DON'T suck up his semen. Here's my thought: can we guarantee that this man [who is willing to get his cock sucked] is a vanilla-type person, who isn't otherwise putting himself in risky sexual situations? It's one thing visiting squeaky clean providers who check themselves religiously, don't use drugs or otherwise act risky..but who is the man willing to get his penis sucked by another man? Another one of her clients? Maybe? Or a hustler who engages in unsafe behavior for money, drugs, etc? Sorry for the possible prejudice here, but I'd be very, very careful.

Now, I can't resist asking the question: what sort of pretzel-like contortion do you go through to suck your own cock and were you able to do it first try?

Totally forthright here too

My experience had a little different twist to it.

It came as an invite by a couple to join them in a threesome.  We were at swinger party so I understood the guests where a sexually liberated crowd.  My orientation is profoundly heterosexual and I wouldn’t seek out or engage a man for any type of sexual activity.  They'd come from out of state so I didn’t know them beforehand but we hit it off from the beginning.  The husband was intelligent and the wife was very alluring.  He seemed straight in every aspect and all our public interaction was focused on the wife.

As the evening progressed the three of us adjourned to a back room together.  I’ve had previous encounters with couples but all limited to sharing the willing woman.  Once we alone he seemed content to lay at the foot of the bed and just watch her and I together.  At one point during oral 69 play with her on top, he casually leaned over and started giving me head.  I was kind of shocked at first but didn’t resist his actions.  She also didn’t initially react but after a few minutes this turned her on immensely.  From there the whole situation transitioned to a higher erotic plane.  But during the balance of our time together no additional direct sexual contact ensued between he and I again.

The odd thing is in the context of the encounter it didn’t seem that unusual.  I’m fairly open-minded and my impression was this wasn’t something they’d planned or normally did.  This spontaneity appears to have added to her enjoyment.  Had I known or sensed this is what they had in mind I probably would’ve passed on this encounter.  But now that my apprehensions are breached, I might not be so inclined to reject out of hand the possiblities and would return the favor given this positive experience.  But I don’t feel this is something I’d look for or find enjoyable otherwise.
