A/N:I dont own Death Note.
L had finally come home from a case to his lovely wife, Bella, her insane sister, Della, and his two children, Elliot and Elle. They were identical twins,(except for the hair cuts) but completely different personality-wise. Elle took after her aunt Della and was a trouble maker. Elliot was a straight A student who always put his best foot forward. The two never got along, which is why what L saw this day shocked him.
"Lawli!"
He was greeted by Bella at the door with a hug and kiss. "Hello, Bella."
"Hey, fuckass is home!" Della said cheerfully. L had gotten used to her cursing, taking it as a form of either endearment or a greeting of sorts. "Hello, Della. How are the children?" "They're in their room." He nodded then went up to say hello to his children. He opened to door ready to greet them both with open arms, but instead, his jaw dropped. The two were kissing, Elle on top of her brother, and L thought he saw a little bit of tongue. "Elliot...Elle...WHAT IN GODS NAME ARE YOU TWO DOING?" He shouted, surprising his children. Elliot jumped, causing Elle to fall to the floor. "Uh, um, dad, its not what it looks like!" Elliot had been afraid of getting caught, of getting in trouble, meanwhile, Elle was just bored. She had decided to shock her twin, but didn't plan on shocking her father as well. "Yeah, dad!" "THIS IS ODD AND I DONT KNOW WHAT TO SAY ABOUT IT!" L was gonna need a therapy session after this. He walked downstairs. "Bella, you need to talk to them." "Why what's wrong?" "Just go talk to them!" "Ok, ok!" She went upstairs.
~15 minutes later~
Bella walked downstairs, a shocked look on her face. "L, do you know what they were doing up there?" "Yes. It was traumatizing."
Della wanted to know what happened. "What? What is it?" "We dont wanna talk about it." "TELL ME!" "NO!" L and Bella shouted in unison.
