(This story is generally fictional, though a variety of details are true - especially those that were photographed)
Saturday morning, stroking as my wife flicked my nipple, already surprisingly horny after unexpectedly running across some trans porn at a follower's own tumblr. Surprisingly sexy trans porn, hard cock action in simple settings. The sense of forbidden in finding such sexy pictures while horny is an attraction of its own, though rarely indulged. One stretching back to my first exposure decades ago, renting a room from a married couple with several kinks which have influenced me, and my wife, over the years.
Being so turned on by the secret, I'd also looked at a set of group sex pictures involving my not exactly mother-in-law, the second wife of my father-in-law. Those pictures were taken from a borrowed camera's memory chip, that my wife had removed from her father's camera. The first image of the series was almost chaste compared to the rest. Except for the one heavy breast centered in a triangle, nothing can be directly seen of their naked fucking. Possibly, the intent was anonymity, for sharing digitally.
An intent that fades by the second shot, as the logic of group sex takes over, one ruled by opportunity. In this case, Leisa, legs wide, being fucked while sucking off the man kneeling at her face, her hands pulling his cock into her mouth, a breast hanging, with a pale nipple. The sucked man's middle finger slid over her hood, between her pussy lips, and down along the other's man's buried cock.
The porn was a powerful turn-on, which her experienced touch on my nipple quickly increased. Asking why I seemed so aroused so quickly, it was difficult to say anything but the simple truth, telling her about the porn, without getting much into details. She is familiar with one site I visit regularly, with user submitted pictures that are 'screened' - the first published set always includes the woman with the name of the website in the shot.
Mainly due, amusingly, to aesthetic differences with the site owner regarding my wife's decisions of what to publish, her pictures have tended to be sporadically available online, until tumblr came along.
Leaning against me, she murmured 'Why do people take pictures?'
'It .. makes them horny .. you know that' I replied, then went on, 'like Leisa .. hot .. getting fucked.'
Leisa being the second wife of my wife's father, It was quickly apparent when initially meeting her that she had a deep interest in sex, without shyness, or more than occasionally, politeness. This can get a bit awkward with age, but over the years, we have stumbled across (and even take some) pictures of them in various states of undress - in boutiques, on a nude beach with us, and in their bedroom.
The first apparently private shots we encountered were softer core pictures among prints from various vacations. Like those taken under the table of a cafe, Leisa without panties but with legs spread, followed by a couple of shots of her large braless breasts, essentially exposed by the way her top was barely buttoned.
Though soft core may not be quite right, as you could see how her pussy lips were spread and glistening, her nipples a bit crinkled under the stretched white material that revealed just how large her aerola were. Both wine glasses were empty, a viewer easily imagining that she had been fingered in public first, considering the sexy expression on her face.
Another set was a series with her in a large wrapped towel, though it left her breasts uncovered. She was involved with another woman in a hotel room. Partially spontaneous, posing in bath towels, Leisa pulling down a much younger woman's bath towel as the series continued. A series obviously taken by Leisa's husband, and not the other woman's partner, who partially appeared in a couple of the initial pictures. The last shot showed the two women kissing, breasts touching, tongues likely deep in each other's mouths from the way they looked in profile.
A further public set we both saw was a birthday gift of two larger framed pictures from a trip with another couple on a sailboat - in both pictures, one taken from the mast, her topless breasts were prominently displayed.
Of course, this was quite in the past, and all the images were prints. Making them somewhat unique, unlike digital data, and thus effectively impossible to share.
However, the digital pictures my wife discovered on their camera after borrowing it were at a different level entirely. They were incredibly explicit, and it was obvious that the photographer had really enjoyed taking them. The images were of group sex, and neither of the two men were Leisa's husband. Thus leading the viewer to pretty much draw the only reasonable conclusion, that her husband was the one behind the camera, watching his wife fucking and sucking other men, obviously a willing observer of what was going on.
My wife had been fairly shocked, though differently from me, after I'd looked at the images briefly. Later, wanting to look at them in more detail without her around, it was obvious that she thought such pictures were unacceptable, leaving a gap on the chip.
But now, hot stroking making me bolder, I brought up the truth that a number of people like taking and being in erotic pictures, reminding her of what she had found on that borrowed camera. Remembering how almost all pictures had been composed to preserve a certain amount of privacy for Leisa, except the one that showed the faces of all three, his wife in the middle.
'I deleted those pictures' she replied, 'they were just too much.' That was several years ago, and the couple of times the subject had come up at all, it was instantly closed. This morning, her nipple play continued as we spoke, with predictable pleasure, if unanticipated excitement, talking about Leisa having sex with two men, her husband, always out of the frame, taking pictures.
