I've always considered myself a fairly average guy in most respects. A moderately attractive, but unimposing heterosexual; within the norms of sexual appetite, preferences, and porn consumption. Until that last one changed with my divorce, and the dominoes started to fall.
Once the sex in my marriage began to wane, I'd watch porn whenever I found myself home alone with time on my hands. Back then, a protracted wank session might last as long as an hour or two, but always with one ear open for the sound of her car in the drive and the garage door opening. Although that risk added a furtive element that carried a certain appeal, I had no idea how much I was missing until I was living alone.
Watching porn can be a much richer experience when you know you won't be interrupted. There's the additional perk of being able to incorporate toys, or cross-dress, or whatever floats your boat. I didn't have inclinations along those lines, but I did take delight in the freeing feeling of being naked, comfortable, and able to edge as long as I wanted; knowing that the eventual climax would be of my choosing, in my time. Most importantly, it would not be stolen away or rushed by an unexpected arrival.
My porn consumption had been static for years. The same theme, mainly beautiful naked women, was usually enough; and if those women were sucking cock, it typically wasn't a very long session. But I found that once I began devoting more and more time to it, those previously exciting images lost some of their intensity. I was still a fan of all the same things, but they no longer stoked the same desire. I guess that's what porn consumers mean when they say their "tastes evolved over time".
I was accustomed to getting off to a picture of a beautiful girl sucking a cock, usually with a hot caption. I tended to save my favorites, like the one where a guy about to be serviced looks down at the woman kneeling in front of him and tells her:
I want you to relieve me of my burden. My balls are full of sperm that I need to release, and I want to unload them into your stomach.
That kind of shit always did it for me.
When my tastes did evolve, it was along lines so predictable as to be boring. I went from imaging myself as the man being sucked, to the person doing the sucking. I mean, how often have you heard that one? I only deviated from the standard path in that I pictured myself as the
person
doing the sucking, not the woman. I had no desire to be a woman, or even to feel like one. Despite all the captions suggesting I would love to wear panties (if not entire female wardrobes), the thought did nothing for me. What I saw when I looked at the cocksuckers was not their gender so much as their passion. I particularly identified with the ones who were submissive. Their expressions of worship, gratitude, and variations on those feelings resonated with my desires, sending me through the roof.
Once I imagined myself as the cocksucker, it was a short trip to imagining eating the cum. After all, it was a logical progression. The culmination of the activity; the most powerfully charged part of the whole experience. Something men understand completely, and women can only imagine by extension. Cum eating became my favorite flavor of cocksucking porn. It was inevitable, I couldn't resist a caption like:
She played with it. She reveled in the thickness of it, then relished the taste as she swallowed it down.
It would make me blow every time!
