So there's a lovely list of prompts
here and of course my brain went "ooh, Lucius" and yup, this is the result. They got reworded a bit to sound more like something Lucius or Draco would say, but the idea is still there.
Warnings for sexual innuendo and silly. Drabbles rated PG.
"Would you care for some dark meat, Miss Parkinson?"
"Father!"
"Draco?"
Lucius looked at his son. For some reason the boy looked horribly scandalized and annoyed.
"She's my girlfriend!"
"Yes, and I thought she might care for some of the thigh meat. Is that a problem?"
He looked to 'Cissa, to see if she could explain this behavior. She looked like she was trying hard not to laugh. Draco looked angry, and Pansy, well, damn. He'd done it again. This was why he wasn't allowed near the nunnery anymore. His innate coquettishness was a curse, really.
"Father, your balls are hanging far too low. Scorpius can reach them there."
Lucius smirked.
"Do you have any idea how dirty that sounds? Looks like you inherited my unintentional flirting skills."
Draco rolled his eyes.
"Just move your balls, please. And stop reading sexual innuendo into everything I say."
"Turnabout's fair play, my boy, turnabout's fair play."
"I did not do that to you!"
"I offered Pansy dark meat and you didn't speak to me for a week."
"That may have been a slight overreaction, I'll admit. But it did sound like you were flirting."
"Draco, if I breathed around her, you accused me of flirting."
Draco put his head in his hands. There were some arguments he was not going to win.
"Look papa, check out Rudolf's honker! Now that's a big one!"
Draco and Lucius looked at each other, and broke out into laughter. Scorpius looked from one to the other, confused. Then he looked to his grandmother.
"Grandmama, what's so funny?"
"It's a bit hard to explain, dear. There's a running joke between your father and grandfather, and you just unintentionally joined in.
"I think he won," Draco said, between gasps and giggles. "Neither one of us is ever going to manage to say anything as completely unintentionally suggestive as that."
Lucius nodded his assent, and 'Cissa shook her head.
"Men."
