For the character question, Charles and 14! If you're willing to do more than one, also 4 and 5! :)
14. Charles - ingrained habits/forces of habit
In answer to this character headcanon ask meme https://pinkoptics.tumblr.com/post/160822050415/send-me-a-character-a-number-and-ill-tell-you
It seems I decided to turn these headcanon asks into drabbles. Do not know if I will continue in that vein, but should I do so they will henceforth be known as the Headcanon Drabbles!
He was tapping the tip against his lips. Lips that were already obscenely red, now made all the more so by wet flicks of Charles’ tongue. He let the tip slip slowly between those gorgeous lips, humming absently, taking in a bit more, then backing off, before repeating the motion. All Erik could do was watch, driven to distraction, and hopelessly ensnared by the most perfect pair of wet, berry red lips he had even seen.
Soon, it was more than he could bear.
With a small surge of power, the metallic pen whipped out of Charles’ sinful mouth and into Erik’s hand.
Charles gaped, lips falling apart so that they made the perfect ‘o’. This did nothing to stem the rising tide of Erik’s arousal.
“Erik, I’m nearly done grading these papers. I know it’s getting late, and you wanted to watch Forged in Fire, but I hardly think that’s the most mature way to get my attention.”
It was Erik’s turn to gape. “Do you really not know?”
Charles’ brow furrowed. “Know what?”
Slightly incredulous, Erik pushed his mental image of Charles fellating his pen into Charles’ mind.
This time Charles didn’t gape, he blanched. “No- I- there’s no way I look *that* filthy when I do that. That- that’s- that’s pornographic.”
Erik raised both eyebrows. “Why do you think I’m always coming on to you whenever you’re writing?”
Erik wasn’t a telepath but he could see Charles flipping back through his memories of their sexual encounters and knew the moment realization slowly began to dawn. What happened next was one of Erik’s favourite things. A deep pink flush spread across both his cheeks and Erik knew, intimately, that it was travelling down past Charles’ collar to stain the top of his chest.
“Oh god. Please tell me I don’t do that in front of others.”
“Any time you’re concentrating, Schatz.”
Charles’ head dropped to the table and a small moan of dismay. “Why have you never told me?”
I always imagine Charles, when he’s grading papers, writing papers for scientific journals, doing the New York Times crossword (because YOU KNOW Charles totally does that), that he always has the tip of his pen/pencil against his bottom lip or just a little bit inside his mouth.
And those moments?
Drive Erik mad.
Also ‘Forged in Fire’ is an American reality contest program about blacksmiths forging swords. I imagine Erik watches it, and gets all irritated and makes acerbic comments about their efforts because he could do it so much better and faster. Charles just laughs and asks why they bother watching it if their lack of craftsmanship annoys Erik so much.
Two headcanons for the price of one!
