Title: One Hell of a Lover

Rating: M

Fandom: Black Butler/Kuroshitsuji

Pairings: Main- Sebastian/Grell and *one-sided* Grell/Crazy!William

A/N: Okay, so recently I've been staying up most of the night bored. So I started watching anime again and I came across Black Butler. As I'm watching it of course as a fangirl I'm slashing almost anything. So when I saw Grell for the first time, the wheels in my head started to turn and then the plot bunnies started to nibble at my toes. I scrapped so many ideas before this one came out. It's incredibly OOC and for that I apologize for those who don't like that. So I will say this now... IF YOU DO NOT LIKE DO NOT READ! FLAMES WILL BE USED FOR S'MORES! Anyway this was supposed to be a One Shot, but I've started to work on a second part, but I suppose this could be read as a stand alone let me know what you think. Okay? Read/Comment/Fave! And get a muffin!

Sebastian had to admit...Undertaker really did lay Grell out beautifully. Sebastian stared down at the shinigami sadly and knelt down next to the coffin. The funeral wasn't until tomorrow so he took the time to say one last good bye. He reached over and stroked that beautifully pale cheek that was icy to the touch. Grell's red hair was flowing around him and his body was surrounded by red roses and carnations. He was dressed up in his red dress that Sebastian always thought made him look stunning. He stared down at Grells' neck, his heart tightening in his chest. He touched the spot fondly and tried one last time to feel that presence in the back of his mind that told him Grell was still there. It was in vain, but could you blame him?

His mating mark. A demon only takes one mate in their lifetime. Someone that they will spend eternity with. Someone the will love no matter what. It was ironic...he never thought he'd even so much as like the reaper when he first met him, yet Sebastian took the reaper into his arms, into his bed, and into his life.

That night their love making had been soft, gentle. It was a feeling Sebastian still holds to heart. Grell on his lap moving slowly while their fingers explored each others bodies. Sebastian had pushed Grell's hair back behind his shoulder their eyes never breaking, and he gave him a soft kiss. His hands wound around Grells' back and rubbed his skin and his lips had moved to the base of his neck where the muscle met the shoulder and bit down until he drew blood. In that moment the two were bound for eternity, demon and reaper.

Eternity was cut short though when William found out what had happened between the two he became enraged. When Grell had returned to the reaper world to get his list for the night William killed him in cold blood. Sebastian, feeling his mate's distress had run to his lover but he was too late. And William had disappeared with Grell's soul. Leaving a message in Grells' own blood: If I can't have him, no one can.

Sebastian pulled his hand away and moved it to Grell's hair. "So beautiful, my love. Even in death your beauty never fades," he said. He could practically feel Grell at his shoulder squealing like a love sick girl. A smile came to his lips at the thought. He leaned down and pressed his lips to Grells' one last time.

They were still so soft...still so full. They lacked their usual warmth but Sebastian didn't care. The feeling of their lips together one last time drowned the coolness of death. When he pulled away Sebastian simply rested his forehead against Grells' closing his eyes and allowed himself to fully grieve. No blubbering, no tears. Just silence as he sat there with his mate.

"You can have him back you know..." a voice sounded in the room. Sebastian didn't move or even acknowledge the voice. He just sat there next to his mate, his one and only. Undertaker sighed and approached the coffin and stood on the other side of it looking down at the two. "Sebastian...if you go find William and win back Grell's soul you may yet have a chance to save him, isn't that what you want? To have him back in your arms?" he asked crossing his arms in front of his chest.

Sebastian looked up at Undertaker with pain filled eyes and he looked down at Grell again. Yes...he would love to have Grell in his arms again. To be able to hold him close, to make love to him, whisper sweet nothings in his ear. He pushed back Grell's hair from his face in a loving gesture and looked up at Undertaker.

"Will you..."

"I will guard him with my life," Undertaker cut him off with one of his grins. "You're not the only one that loves him demon," he said. Sebastian nodded and leaned down to kiss Grell's lips one last time.

"I will get you back my love, I promise," he vowed and left quickly. He was going to find William, and when he did...he was going to destroy him. Undertaker watched the demon leave and looked at his young friend in the coffin. He smiled and pet his hand gently.

"You have one hell of a lover."
