I work as head of IT for a multi-county health care organization, am in my early 50s, and, up to the start of this story which took place about a decade ago, led a fairly normal life: married, three kids, nice house, vanilla lifestyle and very vanilla sex life.
One of the addictions counselors in the office was "out" but not flamboyantly so. He came across as quite low-key and normal, slightly over 6 feet tall, good-looking, about 10 years younger than I, seemed to be in good shape - the prototypical "tall, dark and handsome" type that the ladies in the office swooned over in vain. We gradually formed an office friendship, nothing outside of work but we would exchange pleasantries and occasionally talk in the break room or over lunch. I respected him for having had the courage to come out when he was young, in the late 80s, in a pretty conservative area of the country, at a time when homosexuality was still considered aberrant by a majority of society.
One of my job functions was to perform maintenance on the agency databases, which meant updating each computer in addition to the servers, so I would occasionally call Steve to schedule access to his computer. He'd invariably make a joke about making sure he got the porn off before I looked at it, and we'd chuckle, but he never crossed boundaries that would make me uncomfortable.
When smartphones became popular on the market I decided that staff members who worked from multiple offices or worked in the field should have them for ease of accessing email and other work, so I gave Steve one and showed him the basics of its use. He asked about installing apps, and I said that personal use was allowed as long as it didn't conflict with other agency policies or cost the agency extra money.
A few months later he called me to say the phone "wasn't acting right", so I asked a few diagnostic questions, then told him I'd need to look at it. It was running very slowly, so I started looking at memory issues and found that almost the entire memory was used by pictures. I opened the photo app and found several albums, each with hundreds of high-resolution pictures and videos of naked men in various states of sexual activity. I exclaimed, "What the hell, Steve?!?" and looked up to see him staring at me with an expression of panic. He started to reach for the phone and I held it away from him. "I need to take this and figure out what's going on. Depending on what's on here I might have to report it to the director. At a minimum I need to get this shit off here and make sure there's no malware that can infect our systems." He nodded dejectedly and sat down at his desk as I left his office. When I got back to my desk, I made sure the phone was off the network, then made a backup image in case I needed to file a report or wipe the phone.
I looked at the photo app, and saw one folder named "Me", which contained dozens of pictures of a partially or completely naked Steve, most featuring his cock in varying states of erection. I'd never really paid much attention to mens' cocks before except in the occasional porn flick featuring a male star of huge proportion, but there was something about Steve's cock that made me look at it closely. It was very nicely proportioned, seemed to be pretty long and decent girth, with a large mushroom head and wide piss slit. Many of the pictures didn't show his face, just his cock and balls from above, side or below. Some, judging from the background, had been taken in the mens' room down the hall, and it was clear that in those he was going commando, as I could see his belt and khaki pants but never any underwear. These pictures seemed to be in stop motion: the first just the root of his cock and thick bush of pubic hair showing, with the rest of his meat covered by his pants; the next exposing most of the length; the next showing the entire soft cock, with prominent veins running the entire length, criss-crossing, disappearing into his dark pubes; then one with the head getting larger, a darker color, the root of his cock thickening, the tip extending another inch or so past his hand on his pants; then fully erect, jutting out proudly, seemingly 8 or 9 inches long, the thick mushroom head swollen with proud lust, with a stream of clear precum running down the head onto his finger.
