Erik should have known better to think that Charles wouldn't get him back for that accidental teasing, but the brunet was well behaved for so long though that Erik rather forgot there was anything to be gotten back for, so that when it did come about it was an electric shock of surprise.
The man was a dutiful friend, not just boyfriend: he helped Erik take down the chairs before Sean arrived—restocked the espresso machine, turned on the lights in the back room and put away Erik's lunch, unlocked the bathroom. As Erik set out the wares for the day at the espresso maker, Charles got the point of sale machine primed, chattering away happily through the whole process.
It was only when the man went suddenly silent that Erik turned around to see Charles examining the space under the counter where they stored the stools for the kids to use during slow stretches.
"What is it?" he questioned. Charles looked at the height of the bar appraisingly and then at Erik.
"Do you think I could suck you off while you took coffee orders?"
Erik stared—couldn't move, could swallow, couldn't talk—just stared. Charles grinned back mischievously. Was he requesting, like right here and now in the middle of finals week? Or for a later date and time? Or was he just wondering out of a teasing sort of curiosity?
"Do you think," Charles asked, tilting his head to the side gently, blue eyes glinting, "that you could get through a whole transaction with your cock in my mouth?"
Erik choked down a gulp and coughed himself into speech.
"Well, but, I mean, I wouldn't be able to make any coffee," he said, motioning at the space between the cash register and the espresso machine.
Charles followed the motion with his eyes and smiled. He opened his mouth to say something cheeky, but then Sean walked in the back door—chime going off aggravatingly—earning Erik's wrath for the rest of the day.
"Sorry I'm late!" the kid called. "My bike lock wasn't working. I'm just gonna put it back here, is that okay?"
"Put it in the fucking alley and I hope it gets stolen!" Erik shouted back.
"That's fine, Sean," Charles superseded. There was a short silence filled with surprise, and the Sean called back, "Hi, Mr. Xavier. So Angel was telling the truth? You guys are really dating?"
Erik couldn't speak for a moment he was so busy pouring all his anger into one cutting sentence, but Charles replied with a happy affirmative.
Sean poked his flaming mop of hair around the door frame, staring at them nervously.
"So, did I like interrupt something kinky?"
"No," Charles lied with a smile so that if Erik didn't know it was a lie he didn't think he would have been able to tell it was a lie. "I should be going—it's six."
"You—get behind the counter," Erik growled at Sean, and went to walk Charles out the front door.
He held the door open for the little group of early bird customers and then turned to Charles.
"Listen, I wanted to ask you…" he started, pulling Charles' collar up against the cold. The man had forgotten a scarf. How had Erik allowed him to forget a scarf? "A sort of friend is coming to town soon and wanted us all to go out to dinner with him, and I was wondering if you'd like to be my date?"
"Of course, darling. Just tell me the day and time and of course I'll be there," Charles agreed readily, leaning up to kiss him chastely. Erik put his hands on the man's shoulders and deepened the kiss, pushing his tongue against Charles' and reveling in the hot slide of it against his. Although he had just been inside the younger man on Saturday, he was all too willing to do it all over and over and over again.
Charles apparently felt the same: he gripped Erik's hips tightly and couldn't seem to help pressing into them.
"I don't think I can manage to stay up till midnight to take advantage of the café, but maybe we can find an equally sordid venue for you to fuck me in, hmm?" the man moaned against his lips.
"You really are going to be the death of me, Professor," Erik admitted.
Charles pulled away fully, eyes glinting at him without an ounce of shame anywhere in sight. "Oh all right. I'll give you a couple rounds of proper vanilla sex to acclimate you to the basics, and after that we'll try our luck around campus, yes? Start out with my office and work our way up to a lecture hall? It feels just like a production stage, and the acoustics are marvelous."
"I'll start making a list," Erik agreed.
"We'll tick them off one by one. I can hardly wait to get started," Charles growled, and kissed Erik again with vehemence before he took his leave.
"You two just made out on a public sidewalk," Sean retched when he got back. "It was like seeing my parents make out. I think I'm going to be sick."
"I think you're going to be maimed if you don't shut up and quick," Erik growled back. He had a lot to think about, and none of it worked well with Sean whining in the background.
He wondered how many rounds of vanilla sex would be necessary to work his way up to the big leagues. He had never fucked anyone outside of a house before, if you didn't count all those times with Mort, and Erik didn't because they hadn't actually fucked—he had only ever let Mortimer suck him off since the man was so good with his tongue and seemed so avid for it.
Even all those years with Magda they had never strayed from their dorms or then their house—well, his house. Adventurous as she had been outside of the bedroom, she had been incredibly shy in the bedroom. Well, not really shy, since she liked to pretend that she was so much more worldly than he was: more like prudish. Except she liked to think of herself as a wild-woman pushing every boundary known to man. Regardless of what she thought of herself, compared to Charles she was shaping up to be a regular shrinking violet.
Erik wondered how Emma would fit all this in to her estimation of Charles as a sweet little puppy.
"What is it?" Sean questioned nervously.
"What are you talking about?"
Sean looked him up and down like he was coming down with smallpox.
"You're smiling."
He was, he realized, trying to rub it out of his face, but it couldn't be helped.
"So? I'm allowed to smile in my own café."
Sean just stared even harder and then whistled. "Man oh man, you've got it bad."
"Get back to work," he said with a roll of his eyes. Because really, what argument was there for that?
