A/N: Though it's been tweaked and polished a bit, this little drabble was the result of me joining the new Harry Potter Truth or Dare LJ. My prompt was courtesy of Teshara. I'll post the prompt I was given at the end.
Lucius hid in the darkened pumpkin patch, impatiently waiting for the light in the gamekeeper's hut to finally go out.
Then, with all the subtlety and stealth of a master Slytherin, Lucius swiftly and silently sneaked into the barn where the Thestrals were kept.
Finding a conveniently empty stall, Lucius dragged over a fresh bale of hay to sit on. Only then did he remove his precious, stolen booty from the inside pocket of his robes, snickering to himself at his unintended double entendre.
Conjuring a full-length mirror and carefully affixing it to the wall, Lucius quickly stripped and slipped them on, turning this way and that, admiring the way the baby blue silk complimented his complexion and his own baby blues.
Who would have thought that Gertrude Bulstrode's extra-large knickers could look so sexy?
Suddenly, the bright, white light of a camera flash lit up the stall, and Lucius let out a surprisingly girly scream, desperately attempting to cover himself, but to no avail.
The damage had been done.
Severus chuckled richly and examined his rapidly developing handiwork as a mortified Lucius ducked behind the bale of hay and hastily dressed himself.
Admiring the crisp, clear image of a shrieking Lucius Malfoy clad only in a pair of baby blue knickers, Severus knew he had finally acquired something that virtually guaranteed that Lucius would never again harass him on the subject of himself and Lily Evans.
Lucius wouldn't dare.
Prompt by Teshara: Lucius Malfoy, an extra-large pair of women's knickers, a bale of hay
