I posted my little ficlet for hp_kinkfest yesterday. It's Charlie/Draco, which is a pairing I hadn't written before, and I got to try my hand at a few kinks I hadn't written yet! Info/links are below if you're interested in reading. :D
Title: Danger in Frustration
Prompt Number: #92 submitted by blithelybonny
Kink Showcased: intergluteal sex
Summary: Draco doesn't believe in sex before marriage. Charlie's found a loophole.
Warnings/Content Notes: blow jobs, intergluteal sex, light dub-con, dirty talk, first times
Word Count: ~3,700
Author's Notes: I'm not sure if this is what you had in mind when you left the prompt, blithelybonny, but I have a thing for "just the tip" and this prompt seemed like the perfect opportunity to play around with that. But poor Harry was far too noble for such goings on, so Charlie volunteered. :D I know that technically Charlie is a pure-blood too, but I figure he's a very different sort from Draco, yeah?
Thanks so much to the darling capitu for looking this over for me, and to dicta_contrion for being such a fabulous and encouraging beta!
