They can't exactly walk away from Apollo's Café holding hands, though she imagined anyone could read their affection for each other shining off of their faces. It was still considered unprofessional, fraternizing with someone under her command, not to mention they were the only two human Spectres. They could still be reprimanded by the Admirals, though she knew they had more important things to worry about.
She let her hand brush up against his, wanting, not for the first time, that they could just exist as a normal couple. He swung his hand into hers a couple of times. They didn't look at each other when it happened, but small smiles spread on their lips. Warmth spread through her body, and she wondered, "Is this happiness?"
The elevator doors out of the Presidium whooshed open before them. They matched steps as they entered, and when no one followed them in, the elevator closed. They were truly alone at last. Kaidan pressed the button for the Dock, and stepped back. He snaked an arm around her waist and pulled her to him. He used his free hand to tilt her mouth up to his. She parted her lips, flicking her tongue across his. He tasted like bad beer and raw steak. She pushed her hands under his shirt, feeling the indents of his stomach. They backed into the wall just as the elevator came to a stop. Breathless, they jumped apart, Shepard smoothing out her shirt and Kaidan tucking his in. In their luck, no one stood outside, giving them a few minutes to let the heat fade from their cheeks.
Shepard thumbed toward the Normandy. "Meet me at the cargo bay later?"
He snapped to attention and saluted. "Aye aye, ma'am."
As they began their stretch back to the ship, Shepard hooked her pinkie with his.
