****** David's Dad (Has Got it Going On) ******
by afrocurl
Summary
     Charles doesn't know what to do with the crush his son's best friend,
     Erik, has on him. At least not until Erik all but forces himself into
     Charles' lap one night.
Notes
     Written for this_prompt, and as it turned out far longer than I
     thought, I'm posting it here first.
     OP - if you feel comfortable, I'll gift this to you, but otherwise,
     please enjoy!
     Title co-opted from the Bowling for Soup song, Stacey's Mom. Which
     most of you will not have stuck in your heads. Sorry!
See the end of the work for more notes
Charles never wanted to be the Dad who eavesdropped on his son’s conversations,
but there were days when that was impossible. Today was one of those days;
David and Erik - thick as thieves - were talking so loudly that the whole floor
could probably hear them as they made their way down into his apartment.
He tried to block out the conversation, but instead he caught “magazine” and
“go online, man”, and tried to push away the images of his son discussing porn
with his best friend. Even if Charles knew of David’s small collection, he
didn't need to hear David and Erik talking about it.
Not that Charles could begrudge his son's interest in sex, but David and Erik’s
frank conversations only reminded Charles of how lonely he had been for the
last eight years. It still stung to remember Gabrielle's death - he had had
therapists tell him that his phantom leg pains weren’t related to how the
gunshot that killed his wife - and he worked hard to honor his wife’s memory.
That meant he had been nearly celibate for as many years, trying to give David
happy memories of a happy family.
Only as David and Erik kept their conversation going into the apartment,
Charles couldn’t help but get anxious. Erik had always been interested in
Charles. He thought that it could have just been an affectation on Erik's part,
perhaps a passing fancy since his own father had long since passed, but it
hadn’t stopped and it still made Charles uncomfortable.
With David and Erik deep in their conversation, Charles left them alone and
went back to looking at the edits for his latest book.
-
David walked into Charles’ study a few hours later, his face flushed and
excited. “You didn’t come see us,” David said.
“I thought you’d like the privacy.”
David thought that one over for a moment. “Oh.”
“Yes. I know that I shouldn’t pry.”
“Well, Erik was asking about you. Said he wanted you to have this before he
left.” David had a piece of paper in his hand. “He told me I couldn’t read it,
but he was insistent that you get it.”
“Thank you. What did you want for dinner tonight? I think there’s still Thai
leftovers.”
“That’ll work. I’ll heat it up. Be ready in ten?”
“Sure.”
David walked out of the room and Charles tried to steel himself to look at
Erik's message.
Mr. Xavier,
I’m sure you heard what David and I were saying earlier. But that wasn’t all of
it. I want you. I think I've wanted you since I was twelve. You have to know
that I watch you whenever you’re not in your office.
I want to fuck you. Tie you up. Make you come as I work you open.
Erik
Charles reread the note, again, and couldn't focus on anything else. Erik's
admission was too much for him - or it would have been, if Charles hadn't
already gotten used to his long dry spell.
“Dad, dinner’s getting cold!” David yelled from down the hallway. Charles
stuffed the note into a drawer and tried to forget about Erik’s declaration.
-
Charles scrolled through the messages on his phone, saw Erik's thread, and once
again wished he could just pitch the device against the wall. Erik just would
not stop. He'd gone past using David as the messenger - he'd simply resorted to
lurid text, and lots of them.
The most recent one said, "You'd look gorgeous sprawled out on my maroon
sheets." It might have been less suggestive than the others, but it smacked of
finality, of a claim on Erik's part. As if he was sure that Charles would give
in to the promises in all of these messages, and act on them.
Charles clung to his self-restraint anyway: he never once responded to Erik's
myriad texts, and he made a point out of holing up in his study, with the door
firmly closed, whenever Erik came over.
However, just because he wasn't going to act didn't mean that he wasn't going
to react: and how badly he wanted to laugh at the message about the maroon
sheets, but he could still hear Erik's voice in the apartment.
There was a loud click of the front door later and Charles let out a sigh of
relief. Erik had left for the night.
“Dad, is everything okay?” David asked when he opened the study door.
“Wonderful. Just, you know, papers to grade.”
“As I have homework.”
“Precisely.”
“So, dinner?” David asked.
“I’ll make something in a minute. We still have those salmon steaks, right?”
David hummed, and left just after that.
Charles looked at his phone once again before it buzzed. Would you rather have
me under you, would you rather rock into me? Is that why you won't reply?
None of those questions had answers Charles wanted to write out, and so he put
the phone in his pocket and went down into the kitchen, eager to work on
dinner.
-
By the time that he and David had finished preparing and eating dinner, Charles
had received another seven messages from Erik.
The last - the one Erik meant to be the last - simply said 18 soon.
Charles knew exactly what that meant, and wanted so badly to say something - to
dissuade Erik somehow - but he couldn't find the words. How was he to tell
David's best friend about the reality of this, the sheer awkwardness of what he
was proposing?
So Charles stuck to the one thing he had always done, which was: say nothing.
He tried to push Erik’s texts from his mind, but as he drifted off to sleep,
all he thought of was the idea of Erik’s hand gripping his own erection.
-
There was an eerie calm that came over the apartment when David - and Erik -
were not here.
Once a month Charles spent the weekend by himself, content to let David go and
have a night with Gabrielle’s parents. He would never keep David from his in-
laws and he was happy with simply leaving them to their time with their
grandson; he was good with avoiding the stilted little conversations about
school and work and everything else.
But that meant he was alone, with only his manuscript, his grading, and his
cell phone.
His cell phone that kept buzzing with texts from Erik.
I know you’re alone. Let me in.
Charles ignored it. Like he had every other text. He looked at the edits from a
few other colleagues on his book manuscript, and just as he was about to scream
at the stupidity of one comment, his phone buzzed again.
You can’t hold out much longer. I know you’ve been alone for as long as I’ve
lived downstairs.
Erik’s insistence was starting to wear thin on him, but Charles said nothing
and looked back at the comments. He really wanted to lay into his so-called
colleague for the insipid tripe she called "comments" - and just as he was
composing the first sentence someone knocked on his door.
Charles ignored the knock, and tried to focus on his work. There was another
knock, louder than the first.
I’m not leaving, and if you don’t open the door, I’ll just stand here for the
whole floor to see.
Huffing out an annoyed sigh, Charles left his study and walked to the front
door. There was only so much personal embarrassment he could handle within the
apartment, no matter how many people would have trusted Charles’ word over
Erik’s.
“Get in,” he hissed at Erik once the door was open. Erik just stood there,
though, waiting and looking like a spoiled brat.
“What if I don’t want to?” he asked.
“You’ll get in here if you want anything you’ve been thinking about before,”
Charles whispered just before he pushed the door wider.
Erik nearly bowled Charles over in his haste, his feet tangling up in Charles’
as his energy got the better of himself.
Charles closed the door with a decisive movement and only afterwards turned to
look down at the sprawl of Erik on the floor, elbows and knees still sticking
out oddly. “Is this supposed to impress me?” Charles asked.
Erik started to say something but, but it only came out as a mess of noises
without purpose.
“Now you see why I never responded,” Charles said, content to let Erik fumble
around still. “You’re not going to get very far this way.”
Eventually Erik managed to roll to his feet, and he stood up straight under
Charles's considering gaze. “I’m not going to mess this up.”
“You haven’t already?” Charles asked before he turned around and went into the
living room, content to leave Erik alone.
One of his bottles of scotch caught his eye as he walked over. He thought about
it and about the sheer disaster of this night already, and gave in to the amber
temptation.
He poured himself a few generous fingers and sat on the couch, still waiting
for Erik. Just because he had let Erik in did not mean that Charles was going
to do anything else. His self-restraint was still secure, still hadn't been
worn down, and he wasn't going to give in to Erik's blandishments.
He took a long pull from his tumbler and waited. “So what is it you’re going to
do to me, Erik?”
Erik sputtered again as he strode toward Charles, but settled himself by
dropping to his knees in front of Charles. “I’m going to make you come.”
“Is that so? How do you plan to do that?” Charles asked, swirling around the
scotch that remained at the bottom of his glass.
“I’m going to split you open.” Erik was matter of fact in his plans; Charles
had to give him credit for being so sure of himself.
“Do you have everything to do that? I don’t see any lube in your pockets.”
“Lube?”
“Yes, something to put on your fingers so you don’t tear anything inside me.”
Charles watched Erik’s very confused face and laughed.
“What’s so funny?” Erik asked.
“Well, you’ve been so forward. I figured you’d be more prepared.”
“I’m more than prepared. Just--” he trailed off. “Give me a second.”
Erik got up off his knees and ran into the other part of the apartment. He was
back in a minute or two, triumphantly holding up a bottle of lube.
“Did you just steal that from David’s room?”
“I plead the Fifth.”
Charles had to laugh at that, and couldn’t stop himself as he started to
wheeze.
“Don’t laugh at me,” Erik said.
Charles stopped himself from laughing and coughing. “I’d be better off if you
weren’t such a mess.”
“I’m not a mess,” he said forcefully. As if to prove the point, he sank back
down to his position in front of Charles and started to undo Charles’ belt.
“I’ll make you come so quickly you won’t know what it was.”
"Then get to it." He was deliberately passive on the couch, merely watching as
Erik's fingers pulled at his fly, yanked at his clothes.
Erik’s fingers were swift once he had disposed of half of Charles’ clothes,
though Charles could tell that Erik was starting to succumb to his own nerves.
“Slowly, if you know what’s best. You don’t want me to be ruined before you get
to your intended goal.”
Charles knew he shouldn’t have been so forthright with what he wanted, though
he figured Erik really had no clue in the end. Talking was one thing, acting
another and completely different from the first.
Erik managed a few tentative strokes to Charles’ flaccid cock before it rose to
attention. Charles watched as Erik’s face changed; Erik was pleased with
himself.
Charles whistled as he looked at himself, affecting boredom.
“Not impressed?” Erik asked.
“Not with that. That takes no work at all. What you’ve been discussing: that
takes far more work.”
Erik nodded before he reached for the lube and popped the top. Charles shifted
forward, just enough so that his ass was half on the couch and spread his legs.
He felt that was the least he could do for Erik’s sake.
Somehow, Erik managed to coat three of his fingers before he approached
Charles’ hole. “No, that won’t do,” Charles said.
Erik looked confused, bless his soul, before Charles continued. “Start with one
and then work your way up. You had such bravado in your messages that I must
confess I expected much better than this from you.”
The horrible Dad voice was probably too much, but Erik complied, and Charles
let out a breath as Erik’s finger pushed in.
“Slower,” Charles said as he tried to bite back some of the pain. Erik followed
the order well and moved his index finger slowly, in and out.
Charles forced himself not to respond in any other way, because this was not at
all what he wanted. This was for Erik’s sake and his alone.
However, as Erik worked his way into Charles’ body, Charles couldn’t help but
notice just what this whole scenario was doing to Erik already: he only had to
glance down to see how Erik's sizeable erection was already straining against
his jeans.
Just as Erik had found a rhythm for working Charles over, Charles saw Erik’s
face tighten and he moaned. Erik stopped working Charles up and stared down at
himself.
“I’m sorry,” Erik mumbled.
“It’s only your night that hasn’t met expectations.” Charles tried to close his
legs, but Erik was still trapped between them. “If you hurry up, no one will
notice. You don’t want to stick.
“I won’t say a word,” Charles whispered instead and patted Erik’s shoulder.
Slowly, Erik rose from his knees and tried to hide himself.
Without another word, Erik left the apartment and left Charles to himself. With
nothing else to do for another few hours, Charles sprayed the room with
Febreeze to dissipate the smell of lube and Erik’s come and went into his room.
Erik’s earlier work hadn’t flagged, and Charles didn’t know anything else to do
but work it out. He came hard and fast, with vague images of Erik's mouth in a
perfect "O" as he came.
-
Three days passed before Charles saw another text from Erik. He couldn’t say it
was a shock that Erik had even tried again, but Charles had always known Erik
to be a boy with determination.
But this time all Erik’s text said was: Better luck next time?
Charles let out a small laugh. Erik had the balls to think of a next time. That
was impressive.
He still couldn’t bring himself to reply and so Erik’s texts, as before, went
unanswered.
-
At three weeks since Erik’s first attempt, Erik’s texts hadn’t stopped. If
anything, now that Erik had promised another time, Charles felt as if Erik had
tried to exhaust his so far limited sexual repertoire.
The more lurid Erik got, the more Charles’ resistance waned. He felt like
Erik's infatuation could only end with the two of them lying next to each
other, sticky and spent and sated.
Despite all of that, though, Charles had morals. He’d never do anything more
than let Erik act out what he wanted until Erik was legal - which if he looked
at the calendar in the kitchen - was two weeks away.
Two weeks was plenty of time to talk himself out of what he might do.
-
“Dad, can we go shopping for Erik’s present now?” David asked on a clear
morning over breakfast, as Charles tried to multitask eating and grading in the
same space.
“Why do I need to come with you?”
“Because you have a credit card and I want to get him something amazing.”
Charles had to give David credit for honesty. “Okay, give me a minute to finish
this set of labs. No more than twenty minutes.”
“Sure Dad. I’m counting down.” Charles heard nothing else and went back to his
labs, intent to finish without delaying this trip too long as David, he
assumed, finished eating and went to do whatever else seventeen year-olds did
before going out with their parents.
His students were less on the mark than he’d have liked for this point in the
semester, but he also realized as he read over the reports that something had
gone wrong in the lab, affecting everyone’s work.
Feeling less disheartened by the lack of solid work, Charles set down his red
pen and set out to find David and muddle through this shopping expedition.
David’s interest in Erik’s gifts were what Charles thought of as commonplace
for teens: a few games for Erik’s PS3, some iTunes gift cards, and even tickets
to see the Yankees on Opening Day. Charles smiled and let David charge away,
racking up a bunch of things he thought Erik would like.
Not that he said anything of the sort to David, as they kept looking through
Best Buy. He maintained the aloof Dad card as best he could, even as he knew
that Erik would appreciate these gifts, but not as much as he would have
appreciated Charles presented on a silver platter. That one gift only one
person could give Erik.
Erik sent one more text as Charles and David were still out shopping: Get me
something good. ;)
Charles had no doubt that if he gave in to Erik’s tempting offer that Erik’s
birthday would be a very good one.
-
“Is it too much to ask for one photo - or five - before my son goes off to his
Senior Prom?” Charles asked as David fidgeted with his bowtie.
“Yes, Dad, it is. I just want to get going and take these photos with Jean and
go.”
“Well, I want to take in and admire how handsome my son looks today before he
goes off and does whatever it is teens do these days.”
David groused, but stood closer to one of his other friends and let Charles
snap a few photos. In the end, it took no more than fifteen minutes and then
David and Jean were on their way to some Midtown hotel for the night.
Charles looked at the clock on the wall and waited, however. He had said
nothing to David of his plans for the night, but he knew that Erik also knew
when David was supposed to leave.
After months of being worn down, Charles had agreed to let Erik come back for
another try, only this time Charles had every intention of setting the pace.
He’d rather not have Erik’s imagination get away with him - again.
For the first time in months, Charles replied to one of Erik’s texts: Coast is
clear.
Erik knocked on the door within the minute. Unlike the last time, Charles let
him in without protest.
“Happy Birthday,” he said once Erik was safely inside.
“What’d you get me?” The curious look in Erik's eyes spoke volumes.
“I’ll show you in good time. But first let’s sit and have a chat.” Charles
moved onto the couch and let Erik follow. Erik looked uncomfortable against the
couch and so beside himself that Charles let out a small laugh.
“What’s so funny?”
“Nothing. You’re just looking so scared. What happened to the boy who wanted to
split me open?”
“You know,” he said sheepishly.
“And that’s why we’re talking first. Sit closer. I won’t bite.” Charles kept
his eyes trained on Erik’s face as he slowly inched closer. It was a step in
the right direction. “So, you’ve thought about me for some time, yes?”
Erik nodded, but said nothing.
“Why don’t you tell me what else you thought about, besides what was in your
texts.”
“Umm--” Erik stalled.
“I’m not going to mock you for any of it. Promise.”
“I hadn’t imagined much else, actually,” Erik said, his voice tentative and
unsure.
“You never wanted to kiss me? Never wanted to touch me?” Charles was generally
curious about it, almost shocked that such a fantasy was so singularly focused.
“Not really.”
“Well then. Why don’t we start with that.” Charles put one hand against Erik’s
cheek and slowly leaned in to press his lips against Erik’s. Erik stilled for a
moment before he pushed back against Charles’ mouth, his lips parting as he
did.
Charles took that as a good sign and slowly slid his tongue into Erik’s mouth.
Erik tried to make a sound, but Charles cut it off with the finesse of his
tongue against Erik’s. He had no real purpose to the kiss - aside from showing
Erik what it meant to be sensual - and Erik continued to respond in kind; Erik
pushed himself closer still to Charles and grabbed at the nape of Charles’
neck.
When Charles knew he needed air, he broke the kiss, careful not to give the
wrong impression. “That was wonderful,” he said as he caught his breath. “Did
you like that?”
By way of an answer, Erik pressed himself back into Charles’ space and started
to kiss Charles’ lips eagerly. Back against the cushions, Charles gave in to
Erik’s kiss and the way the boy’s energy quickly shifted from nervous to
determined.
Charles would’ve commented on it, but Erik’s lips were busy, nipping and
sucking, tentatively at first. With Erik otherwise occupied, Charles went to
work at moving his hands under Erik’s tee and welcoming the feel of Erik’s
muscles underneath. Erik moved against Charles’ hands and sought to work
against Charles’ neck and collarbone, as he started to rock against Charles's
growing erection, to the rhythm of their kisses.
“Better?” he asked as Erik worked intently against his pulse point.
“Fuck yes!” Erik blurted out when he broke for air. “Never imagined you like
this.”
“Well, that’s a pity.” He moved his hands from the small of Erik’s back to grab
at his ass. Erik moaned in response. “Get up,” he said.
Erik gave him a confused look, but complied.
“We’re not stopping, don’t worry. We’re just going to move into my room. Do you
mind?”
Erik was off the couch faster than Charles thought possible, but he went with
it and led Erik into his own room.
He hadn't done anything to the room to make it clear that there was something
going on, but when they made it through the door, Erik stopped. “Anything
wrong?”
“No,” Erik said as he shook his head. “I just--I just didn’t think we’d get
here.”
“Oh, never think you’re not attractive,” Charles said before he caressed Erik’s
cheek once again. “I’m headstrong and nothing more.”
Charles kissed Erik languidly and moved them both closer to the bed. “Do you
trust me?” he asked when their shins and calves hit the mattress.
“Yes,” Erik whispered.
“Then, let’s get back to business.” Charles pulled himself first onto the
mattress and pulled Erik with him as they kissed.
He felt no reason to stop his exploration of Erik’s body, letting his hands
roam over warm skin and the muscle flexing beneath as Erik did the same.
Charles appreciated that Erik’s movements had slowed, that Erik had found that
this was not meant to be a race.
With time, Charles rolled his hips forward, rutting against Erik. Erik moaned
again at the contact, just before Charles finally tried to take off Erik’s
shirt.
“We’re wearing too much, don’t you think?” He stopped himself from getting the
offending cotton off, waiting for Erik to say something.
“Ummhmm,” Erik mumbled before he tried to nod in agreement, though his head was
caught in the shirt currently.
“Pull it off yourself,” Charles said. Erik complied easily enough and before
Charles knew what had happened, he and Erik were naked against his duvet.
“You are gorgeous,” Charles added when he finally looked at Erik in the pale
light from his night table. “Now, what would you like for your birthday?” He
added a cheeky grin just for show and because he found that he liked the
slightly startled reaction Erik gave in response.
“Can we again?” he asked, and Charles took a second to cotton on.
“Maybe a little later. I want to give you something first.”
Erik simply nodded and focused his attention on Charles.
“Closer,” Charles added before he was face to face with Erik, a few inches
separating them.
Charles pushed himself just a bit closer and started to kiss Erik, with more
intent this time. He meant to pull moans and whimpers from Erik as he could and
just as Erik had to break apart for air, Charles took one hand and trailed it
from Erik’s chest to Erik’s half-hard erection. He pulled, slow but
purposefully, angling himself into a new position to kiss Erik’s neck as he
worked Erik’s erection until it was fully hard.
“Perfect,” Charles murmured as he kept his strokes firm, even as Erik’s hips
tried to buck forward for more friction. Using Erik’s reactions, Charles worked
faster, than slower, finding time to tease Erik’s balls and hole.
Erik’s hips worked faster and faster, and Charles kept up as best as he could
before he finally pulled one final time and Erik stilled as he came onto his
stomach, the duvet and a bit on Charles’ stomach as well.
“Was that what you wanted?” he asked as he looked at Erik’s closed eyes and
chest rising and falling.
“Yes,” Erik said. “Best. Birthday. Ever.”
“It’s not over yet. But I’ll be right back before we do anything else.”
Erik whined, a high pitch from the back of his throat, but Charles ignored it
as he padded into his bathroom. He picked up one hand towel, wet it, and
returned to slowly clean Erik up.
The towel lazily fell to the side of the bed for a minute before Erik turned
towards Charles and placed a chaste kiss against Charles’ cheek.
“You look tired. We’ll rest and then we’ll try one of your ideas. Okay?”
“Hmm,” Erik said before he closed his eyes again.
Charles trailed one hand across Erik’s torso as he started to doze off, content
to let the moment and whatever might come after play out as it willed.
He had pushed himself away from his own sexuality and in the last few months,
Erik had made him realize how much he had cut himself off from his own needs.
Finally giving in to what Erik had been fantasizing about for years only made
Charles’ forced solitude more painful.
He deliberately turned his back on the thought, and focused instead on Erik
dozing. This was the start of something new for both of them.
