New Coldflash Feed

This is an automated AO3 feed who posts from the Barry Allen/Leonard Snart tag on AO3. It is a successor blog for @ao3feed-coldflash which hasn't been active since 2022.

It only generates posts for new stories; additional chapters are not posted. You'll need to subscribe directly to the story on AO3 for that.

If you have restricted your work so that only logged in AO3 users can access it, it will not be picked up by the automated feed.

You may send an ask with a link to your restricted work if you want me to make a new post for it in the feed style here.

Barry bolted from the house with a lame excuse about needing to get an early start to his day, and left out the part where this was the same day he'd started three times in a row. The speedster set sights on a familiar bar—one he hadn't thought he'd return to any time soon. But he needed help. And fast.

Leonard Snart may have the answers Barry needed. It was the sole reason he came to Saints and Sinners, since Barry usually gave the place a wide berth.

Enemy territory, and all that.

These are Gay Adult Male with Adult Male stories (that never got together in cannon of the tv series and movies they where in) that I have loved watching tv shows, movies and reading online fanfics and I wanted to write some of them.

It's Explicit rated because it's Adults and there will be full sex in some of the story's, I will say in each chapter heading which couple from which show to make things clearer.

Each chapter in a different one sort story (for most of them) and I will put in the chapter heading which fandom is which in case you have your favourites.

Happy Pride Mouth.

I hope you enjoy these stories and I hope you have a great day.

Len tightens his grip on the Cold Gun, counting on its light glow and Barry’s eponymous flash to aim, except—

Nothing.

“What do you want, Snart?” The voice is small, tired.

“Not gonna try and arrest me, Flash?” Len challenges.

“Not on these legs, I won’t.”

.or.

Barry Allen has always come to Len for the same thing. Their nighttime rendezvous following Zoom's victory goes a little differently than usual.

Barry Allen is not one for being replaced. However, he's also not one for his life's work being thrown away like a child's drawing. There is absolutely no way he's letting STAR erase Division One after he'd perfected it in every way.

Absolutely not.

And Snart, who is at the threat of something bigger, agrees.

One month to fix things, and also one month of pretending to actively like each other because they're supposed to be co-leaders.

If they do it right, it won't be their last.

The last thing Barry expects today is to be hit in the back of the head with a purse.

No, the last thing Barry expects today is to find out he's a father.

Meanwhile, Snart has his own motives for helping the only agent smart enough to catch him- find his missing sister. And maybe charm Barry into his bed while he's at it.

The problem is quite obvious when he thinks about it. The alcohol has made his mind… maybe not clear, but definitely goal oriented. Problem: No reputable bar would serve a guy nonstop booze in the quantities he's ordering and let him get visibly plastered. It's just irresponsible.

Solution: go to an un-reputable bar.

He knows of one, for sure. The kind of place carding people is considered a suggestion, and if you pass out on the countertop the only thing the bartender will do is wipe down the counter around you.

It's not a good idea. For a number of reasons, including the fact that that particular bar has a particular regular, and…

…and Barry is standing in front of it. --- OR: Just after the events of All Star Team Up, where Barry has the worst group date in history and almost dies to bees (my god), Barry just wants a single night off where he can get drunk enough to forget about his problems.

Leonard didn't sign up to babysit his clearly-hammered nemesis, but if he doesn't do something, Barry might end up even worse off. And that would just ruin the game for him.

Barry didn’t know how he could tell, but he could. That was his Leonard Snart.

It was like something inside him – a white noise that had been playing in the back of his head ever since Ray had told him Snart was gone, a pit in his stomach, a chill in his lungs – finally settled.

“Well, well,” Snart drawled, tilting his head forward as a grin spread across his lips. “Barry Allen, as I live and breathe.”
