Barry looked around the ship in complete annoyance. 

He had volunteered to help the Legends fight Eobard, but it had taken longer than he'd hoped, and they didn't want to go all the way back to 2017, so he had to share a bed with someone of the ship, or sleep on a bench.

His thoughts on that:

Sara: Too scary. She knows how to use her pinky to kill him.

Amara:  Had the strength of any animal. Could also kill him. Also, he felt awkward sleeping with a girl.

Jax: No. Just no. Way, way too awkward. He didn't know him that well.

Stein: Exact same reason, plus too old.

Ray: Maybe, if desperate.

Nate: Maybe. 

Rip: No way in hell.

Mick: Why even consider that?

So, he decided on sleeping in one of the chairs.

As he headed toward Sara's chair, he heard a voice call out, "Where ya going?" 

He recognized the voice, and turned around in shock. 

"Mick? Are you offering me a place to sleep?" Barry asked. Mick nodded. 

"Why not?"

That was how Barry ended up pressed to the wall in Mick's room.

...

Mick was sleeping soundly, but Barry couldn't sleep.

He had always hated sharing a bed with people.

It was so awkward, and the last time he did, he had slept with that person.

"Why aren't you sleeping?" Mick muttered sleepily.

Guess he wasn't sleeping soundly.

"Well... it's just awkward to sleep in the same bed without screwing that person, ya know?" Barry asked.

"Why is that awkwardness keeping you from sleeping?" Mick grumbled.

"I... don't know." 

"Are you gay?" Mick questioned randomly.

"Bi." 

"Close enough. Would it help if I fucked you?" Mick deadpanned.

"Uh... I guess."

"Ok."

Suddenly, Mick flipped him over.

"Is this really a good idea?" Barry asked, but he couldn't help but harden (What? He was super sensitive!).

Mick looked down at him hungrily, and Barry couldn't help but whimper.

"Well, I think it is." Barry nodded.

Mick lifted off his shirt, and Barry moaned at the view.

"You're so sexy," he muttered.

...

For some reason, nobody noticed when Barry snuck out of Mick's room the next day.
