Adam's hand ran over Mac's bare chest as he tried to get his breathing back under control. Mac's hand was rubbing gently up and down his arm; his eyes closed contently. Adam looked up at Mac; a little worry filtering back into his psyche as his heart rate slowed.

"Mac?" Adam's voice was quiet.

"Hmm?" Mac didn't open his eyes; not ready for the conversation he could feel coming.

"Is this…" Adam sighed a little. "Is this a one time thing?" Mac opened his eyes and looked down at Adam. With a wry smile on his lips, he rolled Adam onto his back; covering the younger man's body with his.

"Gimme five minutes…" Mac raised an eyebrow suggestively, and Adam laughed softly.

"That's not what I meant."

"I know," Mac replied seriously. "But I don't have a clear answer for you. Things are more complicated this time." Adam nodded understandingly. Mac looked down Adam's body; huffing out a laugh and touching his dog tags, still around Adam's neck.

"I got into so much trouble for giving you these." There was a fond smile on Mac's lips as he spoke. "I told my CO I got drunk and dropped them in the harbour." Adam laughed softly, letting his hands rub over Mac's arms. He didn't want to make life hard for the older man. The implications of this relationship could be catastrophic for Mac.

"Has it been five minutes yet?" Adam laughed when Mac looked at him in shock. It quickly passed; replaced with a soft smile as Mac leaned in and kissed Adam deeply.

Adam sat nervously in the passenger seat of Mac's car. They were parked in the garage of the lab, and Adam was scared of going inside. Scared someone would look at them and know.

"It's ok," Mac whispered. "Nobody's gonna figure it out." Adam nodded a little; paling when he realised someone might already.

"Danny," Adam whispered; panicked. Mac looked expectantly at Adam, who explained hurriedly. "When I started yesterday he saw me with your tags. I told him about you, and he got this smile on his face. He told me I might run into you again." Mac was smiling wryly, and Adam got the feeling this was the way Danny was often.

"I trust Danny," Mac eventually said. "We shouldn't have anything to worry about." Adam took a deep breath and nodded. Mac leaned over and kissed Adam shortly before moving back and opening his door.

"You ready?" Adam nodded again and opened his door too.

Adam's fears didn't settle on the ride up to the lab but, when he got to his workstation there was a small note there for him. It was in Danny's unmistakable scrawl, and Adam's smiled widely as he read the words on the page.

My lips are sealed.
