I was coming back home from a a late dinner with a friend, and I knew I was gonna have a couple drinks so I'd taken the train. It was about ten pm on a weekday, so the station was nearly deserted. I had about six minutes to wait until my train arrived, so I was just standing on the platform looking at my phone, a little tipsy. There was a random man with grey hair wearing a suit a little ways away. Since the station was empty I gave him plenty of space. After a few minutes he started walking towards me. I was a little nervous to be approached by a random man late at night with nobody around, but I relaxed as he got closer and I saw he was smiling a big, friendly smile, and he also seemed kinda drunk. He was also pretty good looking for an older guy, I assume in his mid fifties.

"Well hi there," he said kinda loud. I smiled and said hi back. "I hope you don't take this wrong but you're absolutely gorgeous." Again I just smiled and said thank you. "You make an old man like me wanna act up a bit," he was still smiling, but he'd started looking at me like he wanted to devour me,and I kinda liked the look. "Oh really?" I said, turning to face him directly. "Act up how?"

"Oh, sooo many ways," he laughed. I liked his laugh, it was warm and friendly. "One pretty simple way I can show you right now." And he started undoing his belt as I watched. He unzipped his fly, and then stuck his right hand down the front of his pants. I was kinda shocked but getting a little turned on, so I was just staring at him, and I literally gasped when he pulled his dick out. He leaned back against the wall and started stroking it while staring at me. "Hmmm, you like this don't you?" he said slyly, "otherwise you'd at least look away." That made me giggle a little and I nodded at him. He laughed at me and said "I knew it. I wouldn't normally approach a beautiful young woman like you for this but I had a feeling you'd go for it."

"Why?" I said shlyly, fully entranced by him and his cock. He had grown quite a bit since he first pulled it out, and as I stared I had the realization that this was the oldest dick I had seen in person. The skin on it was a tad looser than I was used to, and I could see that some of the thick pubes at the base of his shaft were the same grey as his hair. I suddenly got the urge to take his dick into my mouth, but I wasn't that bold.

"I dunno, just my intuition. You look like you're secretly a little freak. And well well well, I was right wasn't I?" He was starting to breath harder and faster, and every now and then his whole body shuddered with waves of pleasure. I was so turned on at this point. My heart was racing and I could feel my pussy twitching a little too. I nodded at him, looked around and saw that we were still alone except for one person waaay on the other end of the platform, took a step towards him so now he was only about two feet away, and pulled my top up fully revealing my tits to him. His jaw dropped as I started squeezing them and pinching my nipples. "Fuuuuuck," he moaned and started jerking his cock even faster, "what a perfect pair of breasts for a perfect young woman. Keep squeezing baby." I did as I was told and kept playing with my tits for him.

"Mmm I'm about to cum so hard for you, watch me real closely now," he whispered. He kept breathing and stroking quickly for another ten seconds or so until he suddenly stopped, seized up, and his cock started shooting rope after rope of glistening cum directly onto the platform floor. I was mesmerized watching his cock convulse, he must've cum for twenty straight seconds. When he finally stopped, he looked at me, smiled, and said "Bet when you left your house tonight you didn't think you'd let an old man at the train station masturbate to you huh?" and laughed. I giggled too and said "no, I didn't."

He put his dick away and just then we heard the horn for the train. "Hey," he said, "real quick let me get one last look at those breasts." I cupped them in my hands and tweaked my nipples one last time before pulling my shirt back down and turning towards the train. "Damn," he sighed, "my ex wife's used to look just like that. You have a good night, lovely" and walked towards a different train car. I got on the train and thought about the experience the whole way home. Later when I was changing I noticed that I had a pretty large wet spot on my panties.
