****** Help from Thor ******
by LorenOlson
Summary
     Loki is in heat but doesn't know he is in heat, and asks for help
     from the only person he knows can help him. Sexual interactions
     ensue.
Notes
     Thor and Loki are supposed to be kinda young in this fic (Loki would
     mentally and physically be at 16 and Thor at 18) so the Underage tag
     is just for caution.
     This is such an old fic, but I've finally gotten up the courage to
     post this! This is my first fic on AO3, so, take it with a grain of
     salt.
See the end of the work for more notes
Thor was waken from his sleep by someone shaking him. Hands grabbing at his
arm, and the quiet calling of his own name,
"Thor? Thor?"
He groaned and said,
"mmm- what?"
The shaking stopped, and he rubbed his eyes. He opened them, but it was
completely dark.
"Hold on a second-"
he said, as he grasped at the darkness for his candle and flint and steel. He
managed to light the candle, and there was Loki, kneeling at his bedside. He
set the candle on his nightstand, and asked,
"Loki?"
Loki replied,
"yes, it's me."
Thor asked in confusion,
"Loki, it's really early. Why are you awake?"
"I don't know. But I was in the middle of a wet dream. And when I woke up
something got triggered. And now-"
"you need my help,"
Thor responded. Loki hung his head, ashamed. Then he nodded yes, his cheeks
reddening. Thor said,
"well come on. Sit down next to me."
Loki nodded and gracefully climbed up onto the bed, settling himself down on
top of the sheets. Thor asked him,
"well, what would you like me to do?"
Loki bit his lip and said,
"well... I was wondering, if you could, umm... I'm a little uncomfortable
asking, but..."
Thor said,
"it's okay. I think I know."
"Thank you, brother,"
Loki said. He cleared his throat and timidly held out a vial of liquid. Thor
took it from him and set it down on his nightstand. He took off his trousers
and pulled his shirt off, throwing them to the side. He turned back to see Loki
staring at his bare chest and biting his lip. He smiled at Loki and took him in
his arms, gently laying him down and laying his head on a soft pillow. He found
the tie on Loki's robe and untied it, gazing upon Loki's form. He was very hard
and precum was dripping from his slit. Thor said,
"oh, Loki..."
Loki said,
"yes, I know. I just woke up and this happened."
Thor pulled Loki's robe from his shoulders as he said,
"you still haven't figured out what has been causing it?"
Loki answered,
"no, I haven't. It's happened to me ever since I was of age."
Thor looked at him and said,
"well, go on. Spread yourself and I'll prepare you."
Loki nodded his head and spread his legs. Thor got in between them, and grabbed
the vial from the nightstand. Loki laid back and looked at the ceiling as Thor
uncorked it and dipped his fingers in. He set it back on the nightstand and
used his dry hand to gently push one of Loki's legs a little farther apart from
the other. He brushed his fingertip against his brother's tight entrance.
He inserted the tip of his forefinger, then pushed it in a little deeper. Loki
whimpered a bit but then sighed and relaxed, Thor slowly moving his forefinger
in and out of Loki's hole. He added a finger and picked up the speed, just
gently scissoring his fingers in and out. Loki closed his eyes and moaned a
little, gently grasping at the sheets under him, balling up bits of it in his
fists.
He pulled his legs back, bending his knees and spreading his legs a bit wider,
then he began moving himself back and forth on Thor's fingers. Thor added a
third finger and Loki stopped his grinding, pushing his legs outward and
kicking at the sheets. He leaned back again and bit his lip, suppressing a
moan.
Thor crooked his fingers and pushed into Loki's prostate, making him moan. Loki
brought one hand up and there was a small flash at the door. A sound spell. He
didn't want to have to use one, but it was becoming more and more obvious that
he did. He brought his hand back to the sheets and squeezed at the sheets
again. Thor withdrew his fingers and Loki sighed.
He got the vial again and poured some of the liquid into his hand, being
generous of the amount he was pouring out. Not too much but a little more than
necessary. He put the vial back and reached down to stroke his length, just
enough to apply the lubricant. Loki looked back at Thor and said, his voice
quiet,
"Thor, please be gentle. You know I'm very sensitive and I just don't want to
get hurt."
Thor looked back to Loki and said,
"oh, I wouldn't dream of hurting you. I'll be very gentle. You know I always
am."
Loki said,
"thank you,"
and leaned back again. Then Thor stopped stroking himself, and he got on his
knees. He lifted up his brother's backside, and pulled him closer. Loki pulled
the pillow with him so that he could still rest his head upon it. Thor rested
his hands on his brother's thighs and lined up his cock with his entrance, the
tip of it brushing Loki's hole. He brought one hand up to run his fingers
through Loki's hair, before slowly and gently pushing inside.
Loki gasped as Thor pushed the head of his cock into Loki's hole, trying not to
tighten around it, Loki attempted to relax the muscles around it and go limp.
Thor pushed in a bit further, going in slowly until he was fully sheathed
inside Loki. He stayed there for a moment, letting Loki get used to it. He
moved the one hand that was in Loki's hair, and began to stroke his fingers
through Loki's raven locks.
Thor could tell, even in the dim light, that he was as beautiful as ever. His
lovely pale skin, his emerald green eyes, his elegant form, he couldn't help
but fall in love. He slowly began to draw out and push back in, Loki digging
his fingernails into the bed sheets. He was quietly whimpering and trying
desperately not to be too loud.
Thor knew Loki wasn't confident of his own magic, he didn't think the sound
spell would work. But Thor knew it would. He was gently pushing in and out of
Loki, keeping the movement slow and gentle. But as he looked back at Loki, he
caught something dark and discolored on his lip. He brushed one of his hands
along his brother's jawline, and asked,
"Loki, what have you done?"
Loki stopped biting his lip and Thor quickly realized, in a desperate attempt
to keep quiet, Loki had bitten down on his lip so hard he had drawn blood. He
leaned forward, so that his face was closer to Loki's. He said,
"Loki. Please don't do that. If keeping yourself quiet means biting down so
hard you draw blood, then I'll have to stop."
"Thor! No, please don't! I need this!"
Loki pleaded. Thor reasoned,
"Then don't bite down so hard. I don't want to see you harmed, especially in my
own hands."
"I won't do it any more, I promise."
"Good," Thor said, running his one hand through Loki's jet black hair. He
picked up the pace a little, it was slow and steady, but enough to draw a good
amount of pleasure. Loki leaned into his touch, nuzzling his head against his
hand. Thor leaned in close and planted a small kiss on Loki's forehead. Sweet
and comforting. Then Loki turned to look straight at Thor. He said,
"oh- come on- you could do- ugh- a lot better than that."
Thor smiled devilishly and leaned down to kiss Loki on the lips. He picked up
the pace and went faster as he inserted his tongue into Loki's mouth, brushing
against his tongue and feeling his way around every little warm spot and every
nook and cranny.
Loki moaned into the kiss, obviously enjoying it very much. He brushed back
with his own tongue, swirling around Thor's in their own little dance. Thor
pulled back, and laughed a little in approval, Loki panting and trying to hold
back moans.
Thor went a bit faster, now at a considerable pace, not too fast, but very nice
indeed. He was hitting Loki's prostate in a consistent rhythm that Loki just
loved, and he showed it, clawing at the sheets and moaning even more. Thor
said,
"Ngh- Loki, tell me if I'm going- too fast."
Loki laughed a little and replied,
"oh gods no, this is, agh- perfect..."
Thor went even faster, now at paramount speed and rhythm, Loki panting even
harder as Thor thrust inside of him, even harder than before, yet staying in
his delicate boundaries. Loki was whimpering and panting and moaning even
louder, saying things like, 'oh yes,' 'oh gods,' 'gods yes,' 'more,' 'please,'
and those among some others. Thor reached his hand down and grasped Loki's
length, beginning to stroke it, nice and fast. After that, Loki just let go,
spouting phrases in Asgardian, scratching and clawing at the sheets, and
moaning loudly, he completely gave up on holding it all in and let out his
pleasure in words and movements, throwing his head back and opening his mouth
wide for long- drawn out moans. All of this was driving Thor crazy, the
panting, the moaning, the clawing, it just made his thrusts even more ragged
and his strokes more rapid and hard.
Soon Loki was practically screaming, until he finally said,
"AGH- Ah, Aah, Thor- THOR, AAh, I'm- I'M- C-COMING- OH- AAH- THOR- OH, Gods!
AAh!"
He screamed out as he shot his seed, spilling all over Thor's hand and their
stomachs, clenching around Thor's length, making him come as well. He buried
himself deep inside Loki as he groaned and spilled his seed in him, the warm,
sticky substance filling Loki. He slowed to a stop, and pulled out, rolling to
the side and staring at the ceiling. Loki was panting and gulping down air, his
own come painting his stomach and Thor's spend deep inside him. He closed his
eyes, and said,
"thank you- brother..."
As he cleaned up with his magic. There they were. Laying there together. Thor
moved closer to Loki and held him in his arms, pulling the blankets over them,
Loki still breathing hard. Thor nuzzled his head into Loki's neck, kissing him
and holding him close. Soon, the two fell asleep in each other's arms. Carrying
their euphoric bliss into their dreams.

"Ooh! I knew it! I knew you two were in love!"
Thor and Loki jolted awake, quickly sitting up in bed and yelping, looking to
see who it was. Sif stood at Thor's bedside, smiling at the two with her arms
crossed.
"Wake up, lover boys! You wouldn't want to get caught, now would you?"
Thor yelled, "Sif! I didn't give you access to my bedchambers!" Loki was just
sitting there, blushing. He had been caught sleeping with Thor. By SIF. He was
so dead. She said,
"so, did you two have fun? From the level of blushing on Loki's face, I'm
guessing you did."
"Sif!" Loki shouted, very obviously embarrassed.
"Sif, if you tell our father I swear to you I'll-"
"you'll what, get me booted from Asgard? Like you could. And don't worry. I'm
not gonna tell. And you're lucky they sent me up to check on you two. You're
late for breakfast."
"What?!" Loki got up, scrambling to put his robe on, and Thor was angrily
glaring at Sif. The two would have to learn to wake up on time if they wanted
to keep their relationship a secret. And learn how to lock a door.
