Math
"I hate math…" Sayu groaned, dropping her head into her hands. Light only shook his head sympathetically, patting her shoulder consolingly.
L spoke up from his crouched position on Sayu's extra chair, turned backwards so that his eyes were peeking over the edge. "I like it."
"L, I'm sorry, but you only like cake," Light said, glancing over his shoulder at L.
L spun the chair around so that he fully faced the two, his thumb raised so that he could mouth at it absentmindedly. Shaking his head, he protested, "No, math is good, too."
Sighing, Light dropped his hand from Sayu's shoulder, who perked up, sensing an upcoming argument in the works. Secretly, she grinned; she hadn't known L long, but when Light and L argued, it never failed to entertain. "Okay, explain to me why you like math so much."
"Well… if you think about it, sex is like math," L said thoughtfully, but there was the beginnings of a smirk tugging at his lips and the hint of a mischievous glint in his eyes.
Light's eyes flew wide open and he choked on air upon hearing this shocking revelation from L. But he supposed he really shouldn't be surprised; as a sex demon, if there was anyone that could make a parallel to sex out of any subject, it would be L himself.
"Excuse me-what?!" Light exclaimed in disbelief, when he had gotten over his choking fit.
"Oh my God, L!" Sayu laughed, sitting back and grinning widely. She hadn't known L very long, but she was seriously starting to really, really like L. Light certainly had chosen well...
Smiling, L gave a nonchalant, one-shouldered shrug, as if his human lover were not staring at him in a mixture of disbelief and anger and his sister was not grinning like some maniac. "Well, you add the bed, subtract the clothes, divide the legs, and pray to God you don't multiply," L explained.
Light's eyebrows trembled a second before he gave up, raising his eyes to the ceiling in an expression of hopelessness. "Oh, L…"he sighed, running a hand over his face.
Ignoring, him, L continued, tapping a finger on his chin."Though in our case, we don't have to worry about multiplying…"
"L, just…" Light waved a hand in front of him, amber eyes begging him to cease and desist, "…just stop when you're ahead, okay? In front of my sister… Jesus."
Thankfully, L remained silent, though the smile remained upon his face.
But then, Sayu spoke up, and it was the last straw for Light.
Grinning, she turned to face her older brother, and told him, "I like him, Light. You should bring him around more often."
