Summary
     You see, Loki doesn’t like girls. He doesn’t even like boys, really,
     he likesmen.
     Thor tells himself he's a great dad. Now, of course, his daughter is
     dating.
Notes
     I'm really diligently working on some WIPs, so of course this needs
     to completely come over me and just happen.
     A whole lot of bad.
     I also did something I've never done before which I called an
     "alternative ending" - just a blurb at the end that throws the whole
     thing into a different light which you may or may not accept.
     Enjoy!
The thing about Thor was, whatever else he was in his life, what he did, he
truly loved his daughter. Would do anything to protect her from the shittiness
of the world. Even Jane, sweet, angry Jane, knew that.
 
Which is why he really isn’t pleased when she brings a boyfriend home. Oh, it’s
not that usual kind of protectiveness. He knows she will date and fall in love
and - Jesus - have sex eventually. That’s not the problem.
 
The problem is, the boy she brings and that holds out his hand for Thor to
shake with a perfectly angelic look on his face will not fall in love with her.
And what he’s playing at - how he’s using her - Thor can easily guess.
 
You see, Loki doesn’t like girls. He doesn’t even like boys, really, he likes
men.
 
In Thor’s opinion, this is visible at first glance. But he has more than his
instinct - and stereotypes - to go on.
 
When Julia’s junior prom was over, he was there to pick her up, but when she
came to meet him, it was with pleading puppy eyes and about a hundred arguments
for why she should be allowed to have a sleepover with Molly. He caved. And
then, just because, he sort of loitered around, thinking he might go and pick
up some beer now that he was gonna be home alone, and that’s when he saw it.
 
One of the chaperones,Thor thinks he may have actually been the PE teacher but
he’s nowhere near sure, standing in the back alley, moaning embarrassingly (and
stupidly loud) as some sweet, skinny thing sucked his dick.
 
Back then, Thor was almost sure Loki saw him looking but simply didn’t bother
to stop. Now he wonders if that’s true or if he’d gone unnoticed.
 
It would take some serious guts to come into Thor’s home, holding his
daughter’s hand and introduce himself if he knew what Thor had witnessed that
night.
 
-
 
“So, what do you think?” Julia asks when Thor is putting the last of the dishes
away. Loki stayed just long enough to help with the washing. Refused a ride.
Bus was fine. Next time, Thor promised.
 
“He’s kinda skinny,” Thor replies, earning himself a deep, dramatic sigh. “But
he sounds smart.”
 
“He is,” Julia agrees, previous annoyance swiftly forgotten. “And not just
about stuff, he also… I don’t know, he just gets me. It’s great.”
 
I’m sure he does, Thor doesn’t say, because she would pick up on it instantly
and he doesn’t want that. He needs to keep an eye on what Loki will do.
 
-
 
“Well, can he?”
 
It’s the puppy eyes again. Thor resists only for show. In truth, he is
intrigued. Julia wants Loki to spend the night. With Thor home, of course.
Nothing untowards going on.
 
He circles through the options. Telling her that they need to keep the doors
open. That Loki will sleep on the couch.
 
He sighs. “He can. But just… don’t get swept up, would you? And stay safe.”
 
“Daaaaaaad!”
 
-
 
Near 2AM. The last beer runs through his system fast and he leaves the
downstairs bathroom door open, pulling himself out with urgent need for relief.
The splash of piss is as loud as it is satisfying and he doesn’t stop even as
he becomes aware of barely audible footsteps.
 
He shakes himself off leisurely, flushes. No rush. His daughter is a heavy
sleeper.
 
“Do you have any beer left?”
 
Loki’s voice is melodic. It’s one of his tells.
 
Also, his request isn’t that at all, it’s him saying I know you saw me. And yet
I’m still here. I wonder why.
 
Thor pulls out two bottles from the top of the fridge and wordlessly leads Loki
to the back porch. Julia’s room has windows to the street.
 
They are perfectly, quietly alone.
 
Sitting down side by side on the porch steps, Thor lets his own bottle just
dangle in his fingers, almost empty, while Loki guzzles his.
 
“We didn’t,” he informs Thor. “We talked feelings and snuggled.”
 
“Is that supposed to placate me?” Thor asks, low and nearing angry. “The more
she cares, the more I’ll make you hurt.”
 
Loki shrugs that off. Like it’s nothing. Like Thor isn’t serious. “Listen.
There’s someone she’s kinda into. She’s way too nice to go for it though. He
has a girlfriend. I’m working on that girlfriend. Once she’s gone… nothing
stopping me and Jules from parting like great friends.”
 
That makes Thor drink his beer. “You’re a good teenage samaritan then, huh?”
 
Loki giggles. The beer is probably working on him already and why wouldn’t it.
He’s a fucking kid. “She was sure you wouldn’t approve of me, it’s half the
reason she started to date me. Imagine her surprise when you’ve been civil.”
 
Thor wonders if that’s the kind of relationship he and his daughter have. She
wants to rebel? Make him mad? She’s never been like that and she’s been a
teenager for a while now. Or is that-
 
He gets so lost in his head that he totally misses Loki putting his beer down
and standing up, only to slink into Thor’s lap.
 
Fuck.
 
“Don’t.” He says it as much to Loki as to himself.
 
“Oh, so this is not why you’ve allowed me around?” Loki whispers, tone sinful,
hips rolling against Thor’s when he says allowed.“Didn’t you want me since you
saw me blowing Mr. Peterson?”
 
Thor’s bottle falls on its side with a sharp click, the beer slowly slipping
over concrete. He wraps his hands around Loki’s hips, almost like he’s
measuring them. He needs no measure to know he’s skinny. Thor could break him.
 
“What is it that makes you think I won’t just kill you here and now?” Thor
breathes against Loki’s lips.
 
“‘Cause that would make Jules real, realupset,” Loki whispers back.
 
“You have two weeks to break that boy up with his girlfriend. If you don’t, no
one will ever find your body.”
 
“Deal.”
 
Instead of shaking his hand, Loki just reaches for his dick. His hands slips
knowingly beneath the band of Thor’s boxers and grasps him.
 
“You’re harder than I thought you would be,” Loki murmurs. “And bigger. But I
wasn’t too wrong there.”
 
“Is that how you pick them? By their dads?”
 
“It’s a factor.”
 
It’s a good thing that Loki is stroking just like that because otherwise Thor
might strangle him. As it is, he just pushes him off until he tumbles down the
two remaining stairs and then reaches for him again, grabbing him by the hair
and dragging his face to where he wants it.
 
Shorts and boxers out of the way, he guides Loki to his dick, unable to resist
thrusting artlessly against his face a couple of times; that anger has to find
its way somewhere.
 
And Loki is limp and a little blissed out in his hands anyway, rubbing his
cheek against Thor’s hard cock like a fucking cat or something, opening his
mouth and sticking his tongue out as he tries to get a lick in.
 
Thor releases him, leaning back. “Get to it,” he orders.
 
And Loki does, taking him in both hands and sucking on the head with a little
moan. Even when he wraps both palms around Thor’s cock there is still space for
his mouth, not to mention that his fingers barely circle fully around the
girth.
 
Thor measured him, now Loki is measuring Thor.
 
And his mouth is good, soft and warm and so, so filthy. He pays no mind to any
dripping saliva or loud slurps, he just goes for it, diving down on Thor’s cock
like he’s starving for it.
 
If he were less angry, Thor would let him play. He’s enjoying it even now, the
nimble tongue playing with his slit, tightening of fingers around the root,
it’s all nice and good, except he is still so pissed.
 
He grabs Loki by the hair, and damn is he discovering something here, that
black mop is thick and silky-smooth and perfect for yanking on, and pushes his
hands away.
 
Forcing his head down is a new experience. Loki gags, and his hands clutch at
Thor’s thighs, nails digging in, but he doesn’t fight it as much as would
probably be reasonable. He lets Thor do what he will, fucking into his throat,
pulling out only to slap his cock against Loki’s cheek, leaving smears all over
his pretty face.
 
Thor has jacked off to the idea of this - of Loki - more than he cares to admit
in the past few days but he’s still ready to blow in shorter time than he would
like, balls tightening when he once again forces Loki down, his hair tickling
his thighs and his hot, choked breaths spilling over his balls.
 
He comes right down Loki’s throat, not letting him up until every last drop is
swallowed.
 
“Fuck,” Loki gasps out when Thor lets him go. His hair is a wild, slightly damp
mane surrounding his red, snot and tears - and worse - streaked face.
 
“Hm,” Thor replies, wiping at Loki’s face in a way that deliberately just
spreads the mess around instead of cleaning it.
 
Loki nuzzles into his hand. Thor expected him to pull away.
 
He’s only just pulling his pants up when Julia’s soft voice comes from inside
of the house.
 
“Dad? Loki?”
 
“Fuck,” he swears under his breath, trying to make sure he’s fully covered.
Loki is wiping his face off into his shirt.
 
Good enough.
 
They sell it to her well, he thinks. They just had a man-talk. He gave Loki a
beer, surely that’s gotta mean he respects him. Treats him like an equal.
 
When Loki says See you in the morning, what he really means is We’re gonna do
this again and Thor is very much on board.
 
===============================================================================
 
Alternative ending
 
“So?” Julia whispers furiously. The room stinks of cigarette smoke; he has no
doubt she’s been smoking non-stop since he went downstairs. “Did it work?”
 
“Like a charm,” Loki smiles. His throat is sore but it’s worth it. “And I got
the whole thing recorded.”
