Train Ride

In January this year I flew over to Germany, then took a train into Austria to meet my wife.
I couldn't get a direct flight to Austria because of bad weather, so along with many others I chose a longer route.
Waiting for the train I got chatting to an older Austrian man who was travelling to the same Austrian city I was.
After being on the train for about an hour, we were told there was going to be a delay due to a heavy snow slide onto the tracks.
Everyone was allowed to use the buffet car to get food, and I met the older Austrian man again. He was travelling first class, so we'd split up when boarding.
Again we chatted until there was an announcement that it was going to take at least a couple of hours until we'd be allowed any further. That's when my new Austrian friend offered to let me accompany him to his first class seat.
Once there he began telling me he'd always wanted to have sex on a train, but had never had the chance.
The more he talked the more lurid he got and strangely I got turned on, listening him telling me how he'd fucked guys in all sorts of places.
Looking at his cock bulge in his trousers it was clear he had an erection and I couldn't stop staring.
Asking me to follow him, I joined him in what was quite a decent sized toilet and shower unit.
He wasted no time dropping his trousers and boxers, then pushed me down. My face was inches away from a heavily veined thick uncircumcised cock and he pulled his foreskin back before putting his cock to my lips.
He spoke in Austrian, then in English saying "Suck it".
I'd never been with a guy before then, yet I found sucking on his cock so naturally and I became incredibly horny, so much so I removed my own trousers and boxers and began stroking my dick as I continued to suck him.
All I did was copy what my wife and previous girlfriends had done for me and he definitely seemed to be enjoying how I gave him head.
After only a few minutes he stood me up, kissed my mouth briefly, then turned me around.
Pushing me so I was leaning over the toilet itself, he began tonguing my arsehole, something I now love having done.
He really went to town licking my rear hole and I didn't even object when he quickly stood up and relatively easily slid his cock up my arsehole.
It surprised me because I fully expected it to hurt a lot more than it did, and I couldn't believe almost from his first few thrusts how amazing it felt.
At one point someone knocked on the door, but he continued fucking me and after only a few minutes his cock erupted up my arsehole.
When he pulled out, he spun me around to kiss me again, then got himself dressed. I did the same having not cum.
Eventually we reached our destination with my wife waiting for me. I'd travelled the rest of the way in first class as his guest, so I introduced him to my wife, who promptly said "I know who he is, I work for him".
I stayed eight days in Austria before my wife and flew home to the UK.
In that time myself and the man who my wife still works for had sex two more times. And each time I found myself wanting him to fuck me harder and harder.
My wife has travelled over three more times this year and each time the man who she works for has insisted I travel with her.
My wife has begun to suspect something is happening sexually between her boss and I, as she knows her boss is gay, yet all she says is "keep him happy", before she has me fuck her.
And just recently I've begun having sex with an older man close to where we live. He's very demanding sexually and I find myself utterly fucked after we've had sex. He doesn't have a big cock, but it is thick and he can fuck for hours.
My only regret is not enjoying men earlier in my life.
