"Well, erm, it all starts off when a mommy and daddy really love each other," Lily starts awkwardly. Harry sits down on the coffee table in front of her and watches her intently. Beside her, Sirius erupts into muffled giggles. James and Remus are grinning widely and blushing hard too.
"Then, you see, because they love each other so much, they, er," Lily stammers, her face turning as red as her hair. Harry's bright green eyes study her as she squirms uncomfortably in her seat. Sirius pulls himself together and turns to Harry.
"Then, mini Prongs, they hug each other really close. Like real real close so that some of the daddy goes into the mommy and the mommy has a baby growing inside her," Sirius tells Harry seriously. While he's talking, he makes these absurd hand gestures that, luckily, Harry wouldn't understand. Harry's eyebrows furrow and James and Remus start laughing.
"Sirius!" Lily exclaims and hits him in the face with a pillow. Sirius laughs and shrugs.
"What? It is true in a way," he winks at Lily and she pulls a face. She hits him again and turns back to Harry when she hears his soft voice.
"So, is that true mommy?" Harry asks innocently. Lily bites her lip. She guesses, it is true, and when her mind flashes to many heated moments with James, she shakes her head and looks at Harry again.
"Yes, darling, it's exactly right," she says. Harry's eyes light up and he grins widely.
"See daddy! I told you mommy and uncle Padfoot know everything!" he exclaims and Sirius looks like Christmas came early.
"I've raised you well!" he says, ruffling Harry's hair, and everyone starts laughing again.
