It was night three of their sting operation. Pierce was both amused and annoyed by how much flair Lucifer put into his house husband persona. It almost made him wonder what it would be like if they were married for real.

Nope. Not going there.

Speak of the devil, he was far too quiet all of a sudden.

"Lucifer?" Pierce called out, "are you out annoying the neighbors again? Luci...".

His voice died out at the sight. Lucifer was lying on the couch, completely shirtless and fast asleep.

Pierce shook his head fondly at the long-legged devil trying to stretch out on the too small couch. He walked over and picked Lucifer up, then he proceeded to carry him up the stairs to the bedroom.

He took of Lucifer's socks and shoes, then undid his belt buckle and slid off the pants. Pierce tried not to blush at the fact that the Devil goes commando. He pulled the covers up over the other man, and before he could think too much on it, placed a kiss on Lucifer's forehead.

He'd been sitting at the desk in the home's office area, looking over the case file, when he heard whimpers from upstairs . He closed the folder and got up to see where the noise was coming from.

Pierce opened the bedroom door to see Lucifer shaking and crying in his sleep.

"No...no...please Dad no...".

Pierce didn't know what he was dreaming about, but it must have been bad if he was begging God for something.

He went over to the bed and gathered the trembling devil into his arms.

"Sshhh, it's okay," Pierce whispered into Lucifer's hair, " you're okay, it's just a bad dream".

Suddenly, Lucifer woke up with a gasp, looking up at the man holding him.

"Cain?".

"Yeah Luce, it's me," Pierce whispered.

To the immortal's shock, Lucifer threw his arms around his neck, crying hysterically.

"Lucifer, what's wrong? What is it?".

"I...I..." He stuttered, trying to get the words out, "I thought I'd killed you again, only this time you weren't getting back up".

"But why would that bother you? Isn't that the whole point of our deal?".

Lucifer let out a wet chuckle, laying his hand on Pierce's cheek. "The problem is, Cain, when we made that deal, I wasn't expecting to fall in love with you".

"You...you love me?!".

"Yes, I do," Lucifer said," and it kills me everytime I have to watch you die. I know we had a deal, and it's selfish of me to think you'd want to change that but...".

The devil was silenced Pierce's lips pressed against him. The kiss increased in intensity as they gripped each other tighter.

They finally broke apart for air, foreheads resting against each other.

"How about we make a new deal?" Pierce asked.

"What did you have in mind, love?".

"I'll stop trying to die, and you start being a little more careful around Decker," he kissed him gently," I don't want to lose you either".

Lucifer gave him a brilliant smile. "It's a deal".

After that, no more words were spoken as the couple made love for the first time. By the time the sun shone through the windows, Lucifer was no longer having nightmares and Marcus 'Cain' Pierce finally felt like there was something worth living for.
