A week later, Shepard meets her at Grissom for lunch. They head back to her classroom so they can have some privacy.
"So, you know how I promised to make it up to you for going to that fundraiser?"
That gets her attention.
"Yeah."
"Well, I got us two tickets to the Colosseum."
Back when humans first hit the galactic scene, they put a lot of effort into spreading their history and culture as a way to introduce themselves properly after the first contact war.
An eccentric krogan warlord heard a tale about the Roman gladiatorial arena. After looking into it, he fell in love. He bought (conquered) a large warehouse on Omega and spent an absurd amount of money recreating a small scale version of the ancient arena. He spared no expense making sure the place matched the legends of old. He even occasionally brought in cloned lions, always a crowd favorite. There were rumors that he planned to flood it for a naval battle. It's an incredibly impractical idea on a space station but everyone agrees he's nuts enough to try it, and possibly determined enough to pull it off.
It's widely hailed as the greatest arena in the galaxy. Jack has always wanted to go but tickets are horrendously expensive and sell out almost instantly.
When she hears that he has tickets, her eyebrows make a bid for orbit.
"What?! How the fuck did you do that?!"
"I might owe Aria a kidney or two."
"Oh this is gonna be fucking sweet! Who's fighting? Are the cats gonna be there? What seats did we get? What-"
"Jack. Jack! I don't know who's fighting but I do know…"
He pauses for effect and she actually holds her breath.
"…we're ringside."
She's on him in a second, forcing her tongue into his mouth and trying to grab every inch of him at once. She starts fumbling with his belt, barely restraining herself from just tearing his clothes off. He grabs her wrists and breaks the searing kiss.
"Jack, we can't, we're at the school."
She leans in and whispers in his ear.
"John, I am going to fuck your brains out on that desk and there isn't a damn thing you can do to stop me."
The rare use of his first name, her tone and message all conspire to break his brain. Not another word goes through his mind before he grabs her ass and attacks her throat with his mouth. She lets out a moan and enjoys his ministrations for a few moments before she disengages.
She stands, grabs him by the front of the shirt and, using her biotics for assistance, throws him down onto her desk. She climbs on top and resumes her invasion of his mouth.
