I have visited two different gloryholes in the last 6 years... about a dozen times altogether.
All but the first two visits, I went alone.
My first introduction was when hubby (he was still boyfriend at the time, we hadn't gotten married yet) took me to a porn theater in Etobicoke.
He had arranged the evening with three other men to show up, each at a specific time.
We got a room, there was a large screen TV with a DVD player. Hubby put in the movie we had selected in the store out front and we waited for the first guy to show up. There was a large cut-out in the wall about 2 ft high and 1 foot wide with a board on our side that you could slide out. When hubby lifted it up we saw there was another board blocking the other side.
Over the next hour each guy showed up and my husband filmed me sucking them individually. Yeah, still have those videos. When one had finished, he let the next guy in. I serviced three beautiful cocks and swallowed all three

It became apparent to the guys outside what was going on in the room so a crowd had formed. Since my Husband screened the three guys previously, he was hesitant to let anyone else in.
However...
Somebody got the room next to us and we could hear he removed his board.
My husband looked at me with an evil grin....
He could tell I was still willing.
"Do you wanna"?
I nodded... my level of horny just ramped up another level.
"Yeah.... I want to".
So he gave a couple of hard taps on the board then lifted it.
A pair of legs appeared, jeans pulled down to his ankles. He was wearing work boots and I loved his strong darkly tanned thighs. He had really hairy legs... and his waist was stark white from where he had obviously never sunbathed nude.
He had a long, thick uncut cock. Straight and vieny. A big swollen cockhead that was slick with his juice. A nice set of large grade-A eggs for balls that were completely unshaven. A thick warm manly bush of black hair. I actually like shaved and unshaved cock and pussy so that didn't bother me at all. I love my men hairy, masculine and strong.... full facial hair and beards are sexy to me.
I got to my knees and took it in my hand. Stroking it affectionately, pulling the foreskin back and forth and watching it snap over the rim of his head.... my mouth watered at the scent of his sweet pre-cum. I curled my lips around it and sucked long and slow, wanting to enjoy this moment.
I gave him a fantastic blowjob for a good 10mins until I consumed my 4th load of the evening.
That was my first.
We went back two weeks later and I serviced three guys at the same hole.
Since our dynamic has always been that I can suck any cock I want... anywhere... anytime... I couldn't resist the urge to do this on my own. Hubby and I talked about it and although he didn't say yes or encourage me to do it, he did remind me of our dynamic and smiled.
"Any cock baby... anywhere, anytime...".
I kind of took that as a unacknowledged dare.
So I did it.
I went back and got myself in trouble LOL
I sucked off two at the gloryhole... then brought another guy into the room and let him fuck my brains out on the floor and the bench they had in the room. I had too. I was so fucking horny I couldn't stop myself.
Yeah, hubby still doesn't know about that.
I've been back on my own three times. He doesn't know about those either. *sigh*
The other gloryhole I occupied is at our swingclub.
I have serviced 22 cocks through that hole.
Sometimes when hubby and I are fucking and we get into our filthy talk about how much I love sucking cocks... he'll ask me to tell him how much I want...
"Tell me baby.... tell me how much cock you need... how much cum you want to swallow". He does this while I am in exctasy and on the threshold of cumming, often backing off to torture me and make me answer him.
"More" is usually my feeble response.
"I want more".
He laughs at me when I am in this state. He totally loves how helpless I become to my own lust.
"You need those cocks don't you.... need to taste them... savor them"
"Yesssssssss"!!! I plead.
And he tells me to "Suck more cock... go find them.... be the little slut I married... the slut you have always been."
It's the pathology of our relationship.
MORE.
Always more.
Maximize pleasure.
