What killed the writer's block

“…C’mon, have another beer.”
“No, man, now I’m elegantly wasted, one more beer and I’ll cross the line between the sophisticate inebriation and that embarrassing moment in which you wet yourself”
“Hey, Justin, weren’t you talking about this couple getting dirty in the tube?”
“OK, now I’m listening”
“What? D’you saw a couple making out in the tube?”
“Oh, yeah, that was some nice snuggling. You see, I was on my way to work, riding the Central Line, when this couple of chavs got into the train in Holborn Station”
“Two chavs? Two boys?”
“No, I mean… a chav and his ‘chavette’”
“That’s lame, dude”
“I’ll pretend you farted instead of speaking, it’s a way to explain what came out of your mouth”
“Keep talking, what the hell happened with those chavs?”
“The thing is, they were a little bit drunk. They weren’t screaming, or making a scene, but they were drunk enough to forget about the people surrounding them, and they smelled a bit of booze. In the beginning they were just whispering to each other’s ear, and being a bit touchy, but then they kissed, and things started to heat up”
“Man a hate when kids make out in public”
“You old fart, what’s wrong with that?”
“Oh, come on, don’t play the ‘modern guy’ role. Do you like to have a girl working on some stupid kid’s boner in front of you?”
“When you were young you get laid in your backyard, during the Bonfire Night! If I’m playing the ‘modern guy’ role, you are pretending to be a prude”
“Don’t mind those two, Justin, just go with your story”
“I was reading some paper I found in an empty seat, so I had other thing to put my eyes on, but you know, when people make out they start to make those wet noises while they kiss”
“Yeah, that ‘smack’ thing every time they open their mouths”
“Precisely. It gets on my nerves! I was trying to read, but after a while I realised I had being reading the same word for ten minutes”
“What was the word?”
“Who cares what…?”
“Pasteurized. A great word, but after ten minutes it becomes the kind of word you use to hide your swearing in front of the kids”
“Uh?”
“Like when you’re dying to say “shit”, but you control yourself and end up saying ‘sugar’”
“So, they were kissing, anything else?”
“I spent like another ten minutes hearing them kissing, so I ended up sneaking a peek”
“I wouldn’t have wait. I would’ve stared since the very beginning”
“That’s disrespectful, man”
“They were making out IN PUBLIC, for God’s sake! If they can’t control themselves, neither can I. Some of those couples make out in public because they like to be stared”
“Well, the thing is, I finally looked at them. They were kissing like crazy!”
“What were you expecting? You had been hearing them French-kissing all the time”
“Yes, but what they were doing could no longer be under the term of ‘French-kissing’. Their lips weren’t touching anymore, only their tongues. Their tongues were completely out of their mouths, swirling and twirling, and the smacking sounds were only produced every time they had to take some air and swallow some saliva”
“I remember doing that in the movie theatre. I used to sit in the back row with some girl, and when the lights were out, it was as if anything was allowed”
“You could touch their tits?”
“Sometimes even their crotch”
“Man, the girls I dated were way more up-tight. I could only kiss them in the beginning, during the commercials, but the main purpose of going to the movie theatre was… well, watch the freaking movie”
“Did they do something more, apart from licking each other‘s throats, Justin?”
“Oh, you bet. By that time, there was only a few people in the train. I work the night shift, I take the 11 pm tube, and by the time you reach Leytonstone there’s even less people. That kind of encouraged them. There was this old lady in the seat next to them, but the started touching one another pretty boldly”
“The lady got quite a show”
“Yeah, the show of her life”
“Oh, but it was too much. They didn’t even started gradually, like touching their waists, or chest. The girl’s hand went directly to the boy’s crotch, and vice versa. She didn’t move her hand, but I’m pretty sure the heat of that hand was making wonders to the chav’s hard-on”
“And what about him?”
“Oh, it was even worse. He started to caress her, like really moving his fingers along her crotch, touching her through her trousers. They weren’t even proper trousers, she was wearing one of those leotard-like things girls are so much into these days”
“Oh, I love those things. Now they only wear that, like that really thin cloth over their legs and ass, and only a regular t-shirt”
“Yeah, they used to wear long shirts over those maillots, but now they don’t care”
“OK, so by the time they were mutually masturbating, we had reached Newbury Park. The train stopped, and the chav just left!”
“… What?!”
“Like that! They were practically screwing their brains out, but he jumped out of the train”
“What about the girl?”
“She just stayed there, horny as hell”
“And what about you?”
“What do you mean?”
“Look at your smile! I’m sure you were sporting a nice boner after all that free semi-porn”
“That was the end of my story, gentlemen. For the little naughty pieces, well, you can get me another pint”
“See that bastard’s smile! Well, anyway, even with a giant tent, you could only wait to find a bathroom”
“Solo style. That girl had nothing to do with you”
“… He’s still smiling. The motherfucker, stop being all Joker and tell us what happened”
“Oh, come on, nothing happened. She was only sixteen, tops”
“Yeah, well, it will be hard to keep thinking about her age after seeing her massaging her boyfriend’s balls in a public place”
“Yeah, some people would try to do something”
“Stop smiling, Justin, it’s getting on my nerves”
“Leave him alone, he’s only human”
“What the hell are you implying?! You didn’t do anything stupid, did you, Justin?”
“Well, she had been sending… certain messages”
“What?! You’re sick, man. Justin, come on, say something. You didn’t…”
“You know what, Justin? I’m gonna get you a pint”
“This is insane… Why are you all assuming that he… And what’s with the approving looks?”
“Hey, bring me another scotch. After all, we can’t let Justin alone with his pint”
“Say something, Justin, for God’s sake!! I don’t wanna see you smiling anymore, STOP SMILING!”
