Summary
     Alternate title: Where did you put my dick, Loki?
     Loki spikes Thor's drink with magic that replaces Thor's dick with a
     vagina. Thor is initially unhappy about it, but comes around.
Notes
     This is the second part of a series, but can be read alone.
See the end of the work for more notes
Since the first night they’d spent together, Loki had been too busy to bring up
sex, and although Thor might have been able to ask him to spare the time, he
was still too embarrassed. He wasn’t even ready to ask if he could sleep in
Loki’s bed.
So it came to Thor as a surprise when Loki’s first mention of anything sexual
was, “Thor, are you very interested in women?”
Loki’d never paid much attention, since he never worried. It was clear that
Thor’s needs were simple enough to only want him, at least for now. And Thor’s
needs didn’t seem to be that great, because he’d yet to come to Loki asking for
anything.
Thor choked on his dinner and went red in the face. Half from embarrassment, as
there were eavesdropping frost giants all around them, half from oxygen lack.
Loki grinned and poured him more hot mulled wine, which he drank in big gulps,
recovering before daring to answer. He had to think about his answer. Not that
he wasn’t interested in women, there were many Asguardians and frost giants
whose shape caught his eye, but Loki was all he’d really ever wanted. True he
would have liked to get a good feel in before he’d married Loki, but he wasn’t
unhappy, “uhhh.”
“This isn’t a trick question, Thor. Do you fancy women or don’t you?”
“I do.” He replied honestly, hoping that Loki’s question was simply out of
curiosity, and wouldn’t lead anywhere.
Thor was right to worry when Loki’s only response was an interested, “Hummm”
and a suggestion that Thor drink his wine before it got cold.
Loki gave Thor a kiss on the head after dinner, “I’ve a meeting to attend to,
would you like to join me?”
“Kartak wanted me to go over the drills we practiced this morning, I promised
I’d meet him.” Since Thor had come to Jotunheim, Loki had several trainers
appointed to him to continue his training to be a great warrior. Loki also gave
him reading to do during the day, “Muscled men are my second favorite only to
well-read muscled men.” He had joked.
“Are you sure you feel alright?” Loki asked, placing a cool hand on Thor’s hot
forehead.
Thor brushed it off lightly, unsure where this sudden worry came from, but too
trustful to think Loki knew something he didn’t, “Of course I’m fine.” Thor
wondered what the problem was. Maybe Loki didn’t trust Thor’s instructor or
maybe he wanted Thor by his side that evening, “Did you not get enough of my
company this evening?” Thor grinned, “Would you like me to hold your hand
through the meeting.”
Loki grinned back and leaned close to his face, “Oh yes, I’d like that a lot. I
could fondle your leg under the table,” he hooked a finger around the wase of
Thor’s pants, “and the attendees will all know what lovely sounds their
Prince’s Princess makes. And then-”
Thor wiggled free and turned away, “I’ll see you after the meeting.”
“No fun.” Loki called after him.
“I’ll make it up to you later.” Thor called back, it was the bravest suggestion
he was capable of.
“Yes you will.” Loki said to himself, “and you’d better bathe before you dare
step into my chambers.”
Thor gave a small wave before turning a corner and slipping out of sight.
Loki chuckled to himself before realizing how long the meeting would feel.
 
Thor hated to admit it, but maybe Loki was right. He didn’t feel quite well,
even Kartak asked if he would rather like to try again in the morning. But Thor
pushed on, and by the end was very exhausted and cold. He requested his bath be
drawn extra hot. Thor, concerned mostly with his stiff shoulders did not notice
the problem at first. He slipped into the too-hot bath with grit teeth, and
told himself to bare it. The warmth felt good on his sore body, but overall he
still felt unwell. Had something been wrong with his dinner? He certainly felt
stomach pain. He pressed his hands on his stomach. He thought about retching,
but the damage of whatever he ingested was probably already done. He’d just
have to wait it out. It wasn’t until he began to wash properly that he
discovered something had gone horribly wrong.
“Where is my dick?” Thor whispered in horror. How had he not noticed before, he
cursed himself before realizing his anger was misplaced. “Lokiii.” He hissed
quietly. Loki, no doubt, was trying very hard not to laugh during his meeting.
Thor could only think of one way to pay Loki back, ignore him, but he knew it
would probably do little good. Loki was the master of patience. He could wait
content and alone, so long as he had something to giggle over. Thor on the
other hand didn’t want to stay like… He examined himself with overly-careful
fingers. Yes, as he guessed, Loki had taken away his penis and given him a
vagina. He’d have to stay like this for who knows how long, probably as long as
it amused Loki. “Loki.” He couldn’t help but quietly curse once again. He
wondered how many princess jokes he’d have to encour before he got his dick
back.
Thor dressed and waited for Loki outside his door. His face was practically
wrinkled from scowling so long. Loki approached him with a large smile, “I see-
”
“Shut up.” Thor insisted, intent on giving Loki as little satisfaction out of
this as possible.
Loki’s smile somehow grew, “So you-”
“Open the door.”
“I like this side of you. I should piss you off more often.” Loki obeyed and
motioned for Thor to enter first. Thor waited for Loki before slamming the door
shut and locking it.
“Who gave you permission to take away my dick?” Thor yelled. If he hadn’t been
so angry, he would have thought of another way to phrase it. Loki held his
sides, trying not to laugh.
“I didn’t think you’d be so angry.” He said, beginning to change out of his
robes.
“You did it without my consent! I thought that was important to you!”
“I wanted to surprise you, I thought you’d like it.” Loki said simply, folding
his robe and laying it in his drawers.
“Well, I don’t like it, Loki. I like being a man. I like having a dick, not a-”
Loki shot him a look of warning.
“You know what I mean.” Thor said defensively. He’d chose the wrong words again
in anger.
“You’re still a man, my darling, muscular, manly man prince.” Loki said as he
leaned on the chair, “Did you try it?” Thor didn’t answer, he was too
embarrassed to answer, but Loki read him and knew he was too afraid to touch
it, as if it wasn’t an ordinary slit of flesh and one that would replace his
dick forever if he dared to get too friendly with it. “If you really don’t like
it, you don’t have to use it. You’ll change back in two days or so anyway.”
“Thank gods.” Thor sighed. He knew Loki wasn’t too cruel, but without having
any information about his current state, he’d begun to assume the worst.
“Are you still mad at me?” Loki asked, taking a step forward.
Thor couldn’t look him in the eye. “no,” he said weakly. He really wanted to be
mad, though.
Loki put his hand on his face and kissed his hair. He pulled Thor lightly
forward, and Thor pressed into him. “Do you want me to touch it?” Loki
whispered, still feeling a little devilish. Thor pushed him off and Loki
grinned before continuing to change. Thor didn’t leave though, he sat on the
bed and put his head in his hands.
“I was hoping we could do this instead. Just this once if you don’t like it, or
not at all if you don’t want to. Seeing as regular penetration-” lust gripped
thor in the gut, he could feel it in his cunt. He didn’t dislike it. “would
take a lot more time, this won’t. Sometimes it hurt a bit at first, even for
the most careful, but I know a spell that would make it painless. If you would
let me, I promise, you’ll enjoy it.”
Thor didn’t want to admit that it sounded tempting. He didn’t want Loki to know
how quickly he’d gone from hating the idea to being interested. He hoped his
silence would serve as a proper answer for now.
“Did the spell hurt?” Loki asked with some sympathy. He’d forgotten that there
were occasional after effects to the spell.
“It was manageable.” Thor huffed, still angry enough to avoid Loki’s eyes. Loki
plopped down next to him and petted his hair.
“It’s left me feeling cold, though.”
“It’s a side effect of the spell, I’m afraid. I could bundle you up, and you
could sleep here if you’d like.”
“I think I’d rather be alone.” Thor said, thinking of the fire in his room.
Loki grinned, “Not like that.” Loki grinned wider. “How do you get any work
done when your mind is occupied full time with lewd schemes?”
“Well it really doesn’t take a lot of thou-”
Thor stood up and left.
 
Thor told himself he wouldn’t. Loki made sure Thor was provided with enough
wood for a heavy fire all evening. He was still cold though. Cold and horny.
He’d been so pent up before all this and hadn’t done anything about it, of
course he wasn’t able to sleep. But he couldn’t just cold bathe it away, at
least he didn’t think he could, and the idea sounded too unpleasant. Unable to
stand it any further, he hastily unlaced his pants, and felt, unsure entirely
what for. His pushed apart skin, and felt for the entrance, his entrance, with
his middle finger. He pressed lightly in and was surprised to find how
different it was from what he’d imagined. What he knew of women was that they
were very sensitive, but even though he felt very ramped up, little pleasure
came from his light touches. He was doing something wrong, he thought. The more
he touched, the wetter he became, but that didn’t help much either. He probed
in and out until he hit something that sent a shock through him. It couldn’t
quite be called pleasure, but he knew that with prompting, it could be. The
spot right above his hole, something stiff and shielded by skin. He touched it
experimentally until he found a way that he liked. He rubbed and touched and
wondered what Loki would say if he knew. Who was he kidding, Loki probably
knew. Loki would be able to smell it on him, or know in some other unbelievable
way. But now Thor couldn’t care, it felt too good now to know the pleasure of a
woman. When he came, he was surprised by the difference, the pleasure ran
through him, and it lingered for a long while before slowly fading.
Thor awoke in the morning surprised. He’d fallen asleep so soundly after he
came that his hands were still in his pants. He quickly laced them and washed
for breakfast.
It wasn’t until dinner that Thor saw Loki. When he shivered, Loki offered him
more hot Mulled wine which he drank heavily.
“I’m surprised you’re so trusting after yesterday’s wine adventure.”
“Well, it’s not like you can give me a second cunt.”
Loki smiled and Thor’s mouth dropped open. He looked at the wine in horror.
“I’m only joking. Were you able to keep warm last night?”
Thor nodded and sipped his wine, hoping that a full mouth would save him from
answering any questions. It didn’t, of course.
“So did you have any fun last night?”
“I don’t know what you’re talking about.” Thor was starting to wonder if the
fellow frost giants couldn’t hear, or just didn’t care.
“Thor, Thor. You’re so many delicious things. You’re so well muscled, and
you’re nice, and beautiful, and loyal. You’re willing to sleep with an evil
frost giant for the sake of your kingdom, and you’ve got a good looking cock,
and probably a pleasurable hole, too.” Thor shut his eyes tight, drank his
wine, and told himself he didn’t just hear that, “But you really need to leave
the lying to me.”
Thor answered with a sigh of defeat.
“Ohhh, so it was fun. I bet you didn’t even miss you dick at all.”
“I’d still like my dick back.” Thor said, truthfully. Having a vagina was fun
for now, but during the day he’d decided that he definitely did like his dick
more. Not that the occasional switch wouldn’t be unbearable, so long as Loki
figured out how to keep him warm while he had it.
“Well that’s not a no.” Loki said pleasantly, “did you learn anything new?”
Thor didn’t care anymore about subtlety at the dinner table, clearly nobody was
listening, “Yes, ac-”
“Wait... don’t tell me. I think I’d much rather you show me.” Loki said
decidedly.
 
Thor tried to get out of training practice but Kartak wouldn’t allow it, even
when Thor told him he had Loki’s permission.
“Loki isn’t your trainer. He doesn’t get a say in this.”
“But he’s your prince.” Thor said with surprise to his indifference.
“You’ll be thanking me when your prince isn’t there to save you when some man
is trying to slit your throat to send him a message.”
“He has a point.” Loki said, watching over the training hall from a balcony.
“Loki!” Thor said with surprise. He’d never really noticed that ledge before.
“Come to my room when you’re done. Don’t work him too hard, Kartak. I need him
to be nimble for me later.” He said before turning away. Thor wondered if Loki
had any decency at all.
“I’ll just warm him up for you.” Kartak smiled. From the weapon wall, he pulled
a heavy stick that he would no doubt use to beat thor with in a moment.
“Thanks.” Loki’s voice echoed back.
Thor had managed not to have the shit beaten out of him, but he was certainly
tired and a little in pain. He considered calling it a night but after a warm
bath he was feeling better. Loki’s door was slightly ajar when he approached
it.
“Loki?” He knocked the frame lightly.
“Come in.” The voice wasn’t Loki’s, but it was.
“Loki?” He asked again as he entered.
An almost entirely naked frost giant woman laid on Loki’s bed. She had a
beautiful body that made Thor momentarily ashamed. He glanced away for a second
before realizing. He closed and locked the door. “Loki, you drank the wine
too?” but he knew this had to be different. Loki’d given Thor a vagina, but
otherwise left him unchanged. This Loki was full female bodied, “Is this what
the woman question was about?” Thor couldn’t keep his eyes on Loki’s face. He
wished the room was better lit.
“It’s something I enjoy every once in a while. But it feels like putting on
clothes that don’t feel comfortable when worn for too long, so don’t get used
to it. But yes, that’s why I asked. I wanted to make sure you’d have interest.”
Thor gave a heavy sigh and pinched the bridge of his nose.
“Hum?”
“Why do you do this after taking away my dick?” Thor wasn’t sure if Loki failed
in planning, or he was just evil.
“Take off your clothes.” Loki commanded. Thor did as he was told. A shiver of
cold and excitement ran through him.
Loki pat the bed next to him and Thor sat.
“I thought we could have some girl time. Show you how to please a woman. And
then if you’re not too tired, I’d like to change back and fuck you.”
Thor was actually glad he didn’t have a dick now, but only so that Loki
wouldn’t see the fastest rising boner in history. His breath seemed to be stuck
to the insides of his lungs.
“Breathe, Thor.” Loki said dryly.
“Right.” Thor choked.
“Kartak didn’t work you too hard, I hope.”
“He did but…” Thor was looking at Loki’s body.
“Well, then I’ll be gentle.” Loki said as he leaned in and kissed Thor. Save
for Loki’s breasts lightly brushing him, it more or less felt the same. It
still tasted like Loki, tongue flicked and teased all the same ways, but his
lips were slightly softer and larger. He didn’t know which way he liked better.
He wasn’t sure it mattered. Loki broke the kiss.
“Show me what you did last night.”
Thor was still embarrassed but it didn’t show as much as before. He reached
down to emulate what he’d done but Loki stopped him.
“On me.”
Now Thor was blushing, “Um… turn around and lean into me.”
Loki did as he was told. He sat in Thor’s lap and put Thor’s hands into his. He
leaned his head on Thor’s shoulder. Thor placed one hand on Loki’s thigh, and
with the other, he traced Loki’s hole, probed in and out until his finger was
wet, and then began playing with that stiff piece of flesh.
“Oh good,” Loki breathed, “I’m glad you found that.” It took a while, and
guidance from Loki’s hands, but soon he was trembling in Thor’s lap, arching
his back, and leaning into him. Loki didn’t move from Thor right away. He
waited for the pleasure to fizzle out first. Thor wrapped his arms around him
in a hug and kissed his bare neck. Loki smiled and laughed with closed eyes.
This wasn’t the laugh that highlighted Thor’s failure or embarrassment. Thor
laughed quietly into Loki’s shoulder. Loki sat up and turned to face him.
“I haven’t touched you yet. Why are you so happy?”
Thor shrugged, “because you’re happy.”
In one motion, Loki changed back into his usual form and shoved Thor onto the
bed. He was all too ready to make Thor beg for mercy for saying something so
unguardedly cute, but something stopped him. Thor’s eyes were shut tight. His
hands flew over his face. The glympse of Thor’s expression Loki was able to
catch looked pained.
Loki blinked and gently touched the side of Thor’s head, petting his soft blond
hair “what’s the matter? If you’re afraid-”
“No,” Thor began before realizing that was somewhat a lie. “Well, yes but it’s
not that.” He was afraid, but his need overshadowed that. “I hurt my back a
little is all.” He explained.
Loki got up from the bed and paced a bit.
“I’m okay.” Thor insisted.
“I told him to play nice today.” Loki hissed.
“He said-”
“I know, that strange men who make attempts on your life wouldn’t play nice.”
Loki said, waving his hand. He stopped walking, looked at Thor, and sighed.
“I’m fine.” Thor continued, sitting up, “see?”
Loki pressed his finger on Thor’s forehead and pushed back gently. Thor fell
back again and tried his hardest to hide the pained expression.
“This won’t do.” Loki said quietly. He sat down behind Thor and examined. Sure
enough, there was a large painful-looking welt that crossed Thor’s back in a
diagonal, “You’re going to have to get a lot better at fighting.” He knew a
spell which would help with the pain, but using it only to fuck Thor into the
mattress would probably make matters worse in the morning.
“Please, Loki.” Thor begged.
Loki raised his hand for silence, “It just hurts when you lay back, right?”
Thor nodded and Loki’s face twisted into a smile, “you can be on top, then.”
It wasn’t how Thor had imagined it would be, but he was desperate enough now
that he didn’t care. At least Loki hadn’t turned him away. He made a mental
note to not get hit on the back and reminded himself that there would be plenty
of time for Loki to fuck him proper.
Loki kissed Thor and slowly pulled him on top of him as he sank down onto the
bed. Thor put his hand on Loki’s chest to steady himself.
“Oh gods damn it.” Thor hissed.
“What now?” Loki asked. He’d been convinced that there were no more possible
problems they could face that evening.
“I didn’t get to touch your breasts.”
Loki laughed and pulled Thor back into a kiss. Thor started to shake a bit as
he thought of what he was about to do.
“Be gentle with me.” Loki smiled. He grabbed the vial of oil off his side
table. Thor continued to kiss him while he stroked oil over his dick before
reaching up and touching Thor with his slick hands. Thor tried not to flinch,
but he did. Loki didn’t notice, Thor thought. Well, he probably did, but at
least he was nice enough not to point it out.
Naturally, he’d caught it, but Loki had more important things to do. He held
the back of Thor’s head, distracting him with kisses, while his other hand
loosened him. He mumbled a spell through the kiss that went unnoticed by Thor.
It would make it painless, as he had promised. Thor pulled away and nodded and
Loki gave a nod and a small smile back and Thor sat up on his knees, straddling
Loki. Loki placed his hands on Thor’s hips but applied no pressure. Loki
carefully guided him in slowly and allowed Thor to take what he needed. Thor
was all nerves and Loki whispered things he couldn’t hear, but were none the
less encouraging. It didn’t take long before he was full and seated against
him.
“Okay?” Loki asked, propping himself up on an elbow.
“Yeah. Can I?”
“Oh gods, yes.” He flopped back on the bed, “Take me.”
Thor couldn’t help but laugh. He wasn’t nervous anymore, he almost forgot how
Loki could scare him. He laid there so passively as Thor rocked his hips,
searching for pleasure. This was different from before. He didn’t need anything
inside him the night before as he fingered that raw nerve but now he saw that
Loki reached something inside him that he’d missed. This is what they sang
about women wanting in drinking songs, to be filled by men. He couldn’t blame
them. Thor found himself rocking harder and faster. He almost felt some shame,
the shame they told women to feel, but he didn’t care anymore. He wanted so
badly to come he’d just about do anything for it. He rocked into Loki, breath
heavy. Loki, sensing Thor was close to orgasm, began thrusting up into him.
That set Thor over the edge. He trembled so badly that he knew he couldn’t
continue to ride Loki. Loki did the rest of the work, completing Thor’s orgasm
before pulling out and finishing. Thor fell forward onto Loki, who pulled a
blanket over him and then wrapped his arms around him, careful not to touch the
sore spot of his back.
“Wait.” Thor said with horror, pushing himself up so he could look loki in the
face. “I can’t get pregnant, right?”
Loki laughed, “technically no. I’d have to be intentional and it would be a lot
of work. Why? Does the thought of being full with my child please you?”
Thor scoffed before leaning back into Loki’s arms.
“I hadn’t asked for permission to come inside. I figure after all the things
I’ve done without your permission I should at least ask before I spill inside
you.”
The words made Thor squirm but he told Loki he wouldn’t mind in the future.
End Notes
     I forget to mention that Loki in his usual form is intersexed but has
     more physical traits generally associated with men. His female form
     is more female body traited and doesn't have a dick.
