Work Text:
At the time this happened, I was a student in uni. I was on the train home, a later train than I normally took, and I was bored. I'd been to the pub with my friends and we'd called it a night just before the trains stopped. We were quite responsible, as uni students went.
It was a ride of maybe twenty minutes back to the side of the university town where I was renting, and I was in a mostly empty carriage. That suited me fine - nothing worse than a late train that has loads of drunken yobs hooting and hollering when you're feeling all mellow and tipsy. I leaned my head on the window for a minute, feeling the vibration of the train.
In the blackness of the window, I saw a reflection. I blinked. I couldn't make out what was happening across the aisle. I turned and found a man with a boy on his lap. Well, that was fine - a father with his son, or something. The boy looked to be about eight or nine, so a bit big to be sitting on Daddy's lap in public, but it was a late train and a nearly empty carriage.
I turned away again to the window and the rushing blackness - but immediately swung back round to stare as my brain caught up to what my eyes were seeing. The man had his hand over the boy's mouth, and there were tears in the boy's eyes.
Was he upset and his father was comforting him? Or, since the man's hand was covering his mouth, was he being abducted and I was the only witness?
I stared at them openly, since neither was looking at me. The boy's eyes were closed now, and the man had his face buried in his son's - if that was his son - brown hair. The movement of the train made them rock slightly in their seat. There was something very odd about the scene, but I struggled to put my finger on it.
At last, I realised that the man's flies were open underneath the boy's bottom. The boy's shorts had been pulled down to the tops of his thighs, which was mostly concealed by his long t-shirt, which occasionally rode up to reveal a flash of creamy thigh.
I was an idiot. The man had his dick out, and his cock was actually inside the boy's arse. He was fucking the boy right there, on the train, in the seat across the aisle from me. The rocking was him slowly grinding his cock inside the boy's tight hole, as the boy struggled uselessly against his relentless embrace.
My breath started to come faster. I couldn't believe it. Who would do that? It was so risky, so insanely dangerous. And I was right there, watching!
The boy's eyes opened again and maybe I moved, because he looked at me. His teary eyes were huge above the man's big hand clamping his mouth shut. He tried to kick his legs and struggle in his rapist's tight hold. He was obviously desperate for help - my help. The man was raping him in public on the train!
Fuck, my dick was about to break my zipper. My own breathing came stertoriously through my nose and was loud in my ears. I heard the rumbling of the train over the tracks and my blood rushing, but underneath that I fancied I could hear the faint squelching noises of the man's thick cock moving inside the boy's tight hole.
I stared as the man slowly moved the boy back and forth, grinding his cock inside him. I also caught a glimpse of the boy's little erection, which was mostly hidden by the hem of his t-shirt. My hard cock twitched in my pants. He was being raped, but his body was reacting with slutty enjoyment at the invasion. I felt like I'd fallen asleep on the train and would wake up any minute to find a sticky mess in my underwear and no boy-fucking.
But I was very much awake. The man turned his head, caught my eye, and smiled. He cast a brief look at the obvious bulge at the crotch of my jeans, which were getting uncomfortable.
I knew I shouldn't. But I was so turned on, the most turned on I'd ever been in my life. I wanted it to be me raping that little boy. I wanted to go over there and thrust my throbbing six-inch prick into his little mouth while the man kept on sodomising him. I'd seen pictures, videos, but nothing could have prepared me for seeing the real thing: a boy being raped as if for my viewing pleasure.
Amazed at myself, I fumbled with my zipper. I pulled out my aching erection and started jacking off furiously as the man continued raping the boy just across the aisle. He wasn't rough, but his thrusts had got harder. I could see his thick erection as it moved in and out of the boy's hole.
The boy's eyes rolled and he made a muffled noise as the man's cock hit something inside him that made his little willy twitch. It was maybe a couple of inches long, with a foreskin that didn't retract. He was completely smooth and I wished the man would undress the boy further so I could get a better look at him.
I saw the door of the carriage open and held my breath, my hand stilling on my pulsing erection. I caught sight of a familiar uniform. The guard had already come by to check our tickets, but he was now about to pass back down the train on his way back to his post.
The guard was a middle-aged man who kept up a brisk pace as he strode down the aisle. I sat there frozen, my stiff cock throbbing in my hand, as he walked straight past me and the man who had his cock buried in his son's arse. He kept the boy in what might look like a loving embrace but was I thought more of a full body hold to prevent him from alerting the guard to what was really going on.
The man was still slowly grinding his cock into the boy's hole in smooth little rocking thrusts. I saw the boy tremble as his prostate was ruthlessly massaged by his rapist's thick cock. The guard didn't even look at them as he passed.
As soon as the guard left and the automatic door closed behind him, I went back to yanking frantically on my dick. The man started to thrust his hips forward into the boy, which got some more high-pitched muffled moans out of him as he was fucked properly. His little stiffy hadn't deflated at any point and I kept getting little flashes of it as his t-shirt rode up.
The man still had his hand across the boy's mouth, and his muffled moans grew louder as the man's thick cock kept rubbing his prostate. The man glanced at me, then pulled up his son's t-shirt so I got an unobstructed view of his little stiff willy. I was thrusting my hips into my masturbating hand, my eyes fixed on that sweet little spike bouncing with every thrust of the man's hard cock.
The boy moaned louder, more urgently, his thighs tensed and flexed, and his little stiffy twitched and jerked in untouched dry orgasm. The prostate orgasm rolled through him and made his prepubescent body shake.
My hand was pumping my erect cock like a machine. My mouth was open, I was gasping for breath. I'd just seen a little boy come dry from being fucked, from being raped, oh, fuck, my cock was pulsing, my balls drawing up -
I leaned forward, my body spasming as I came hard, spattering the back of the train seat with my load as I watched the little boy get fucked through an unwilling orgasm. I groaned and more semen spurted from my cock as I saw the man keep fucking the limp, shuddering eight year old.
He kept working his thick red erection in and out of the boy, and even as I slumped back in my seat, he was still going steady. He fucked the boy in smooth deep thrusts, any resistance the boy had obliterated by his orgasm. He just kept going, taking his time, really enjoying raping this little boy in a public train carriage. I stared, glazed eyed, until the train pulled into my station a few minutes later and I had to pull myself together and tuck my soft dick away.
By the time I got off the train, the man had got the boy's willy stiff again and was working him towards another orgasm as the boy trembled in his lap. I now had wank material for the next several years, and I vowed I was definitely going to take the late train again.
