Chapter Text
"It will be well, Thor," the healer had said. "Our people are compatible. Do not forget that your grandmother was a Jotun. It is from her that you inherited your blessing."
Some blessing. Thor had not realised for years that he was different and that most of his kinsman only had half of what he had within his breeches.
Growing up he had believed that breasts were the only thing he lacked, in the same way that Sif was without a beard. The idea that she was missing a penis and the others had no vaginas had come as a great shock.
So he ought to be glad that his future spouse was someone like him. Someone with both options. And he had met Loki and found him charming, witty and handsome in his way.
It was a wise match. Everyone said so. And the embarrassment of pregnancy would be lessened by the fact that Loki would be thus burdened also. They could comfort each other in their mutual states. And the security of the realm was worth any indignity, surely.
Loki seemed nervous at the start of the ceremony, only answering Thor's attempts at reassuring smiles after a few moments had passed.
They moved like dreamers, repeating the right words, performing the ceremonies, toasting each other at banquet. Thor could practically hear his own heartbeat increasing as the time grew closer and closer when they would be dispatched to consummate their union.
He just hoped that instinct would take over and he would satisfy his new companion.
"Are you worried?" his mother asked under her breath.
Thor nodded in answer.
"Don't be. You will learn each other's bodies soon enough. But you should start now."
He could feel his cheeks burning as he offered Loki his arm.
"It seems duty calls," he said, internally wincing at the thought that Loki may be offended to be considered a duty. But he showed nothing but a smile, laying his hand on Thor's to walk down the corridor side by side.
"It seems strange that we are pushed together, knowing one another so little."
Thor seized on the opportunity. "We need not do anything this night. No-one will know. If you do not want to."
"Oh. I'm sorry. I didn't mean to imply that you are unattractive. Of course, I am looking forward to it."
Thor thought things over as much as he could in the time left. The extent of his sexual experience had been kisses in his youth, before he was summoned to his father and told that he was not like his friends. It was a revelation and a life sentence at the time, his youthful desires nipped in the bud before they had begun. He had dreamed for so long of a partner, someone who was not surprised by his dual sex. Loki could be that person.
They stood at an impasse for a moment once inside, before Loki shrugged off his cloak.
"Would you like to kiss me?" he asked.
Yes, that would be a good start. Thor was tentative at first, gently brushing their lips together, softly opening his mouth when Loki did to deepen it. Loki tasted faintly metallic, a hint of winter clinging to him.
By mutual unspoken agreement, they removed their shirts, looking at one another's bodies with unconcealed curiosity. They seemed very much the same, though the whorls that covered Loki's azure skin were strange and wondrous to Thor's eyes. He wondered if they were natural or some kind of given art.
"Which way shall we...attempt?" he tried.
"Have you a preference?"
He hesitated. "You have done this before?"
Loki tilted his head. "Yes. From both positions. Runts like me are uncommon, but I have met others of my size. But by your question I surmise that you mean that you have not?"
Maybe he didn't know. Thor tried to hide his embarrassment at having to explain.
"My people are not as your people," he said. "The majority have either a cock or a cunt, but not both. Possessing both, I have hidden my body from almost all the realm for its strangeness. I have touched myself, but that's all."
Loki looked horrified. "One or the other? How do they cope? How is the population maintained?"
"Those who can bear children often marry those who can sire children. But my situation being as it is, perhaps as the more experienced, you should penetrate me first, that I might learn from you."
He watched Loki's face fall slightly.
"Did you...not enjoy that arrangement?" he asked.
"I merely fear disappointing you on your first time. I fear my knot is not so big as you may expect."
Thor's mind went blissfully blank for a second in self-defence.
"Your what?"
"My knot. The swelling at the base of my penis that appears when I climax to tie us together in an effort to ensure successful breeding. You must have seen your own when you masturbated?"
Thor's head was shaking without him meaning to.
"I don't think we have those. No-one has ever mentioned anything like that."
"Really? How odd. You're sure you touched yourself correctly?"
If he hadn't been blushing before, he was now.
"My technique was very pleasing, yes."
"And you were able to make yourself spill?"
How could he say it so calmly?
"Of course. I don't think my people have such...organs."
"Huh. May I see it?"
Thor tried to wave a hand nonchalantly for Loki to undo his clothes, as though he wasn't panicking at the thought that he would be seen naked by this haughty, beautiful person.
Loki approached cautiously and unlaced his breeches, slipping them down.
"Oh..."
"What?" Thor asked. "What's wrong with it?"
"It's so thick..."
There was wonder in his voice, and Thor was confused. He had seen other cocks in his time, in the bath house, and his was nothing of note.
His arm looped around Loki's waist, pulling him closer to remove the cloth he wore on his lower half.
Loki's penis was thin but long, so long.
"It won't fit..." Thor breathed.
"Mine won't fit? Thor, you practically have a club between your legs."
"Well, you have a lance."
There was a beat before they both suddenly laughed, finding themselves nude and staring in combined wonder and horror at the other's flaccid members.
"Why did no-one think to mention... This?"
"I have no idea. But I maintain that we don't have to. If you're afraid."
Loki quirked a brow. "Afraid? That sounded like a challenge, husband. Worried that you can't take me?"
They were chest to chest now, noses almost brushing, playful grins on their faces. A second later Thor was pulling Loki firmly against himself to kiss again, far more confident now.
"We can only try."
He led Loki to the bed, flopping down on his back and dragging the lithe Jotun's body on top of him. There was a brief moment of concern when he felt the tip of Loki's cock at his entrance, but he quickly dismissed it. He had tried masturbating with many objects. He would be fine.
A second later he was sitting up in panic, almost dislodging Loki.
"Sorry. Does it hurt?"
"No, but it... It's rippling."
Loki looked at him strangely.
"Yours doesn't do that? Then how do you pleasure yourself and your partner?
"By... By thrusting and touching."
"Isn't that tiring?"
"Well... Energetic, certainly. How do you do it?"
"Well, my cock expands and contracts rhythmically, which rubs most pleasantly against your inner walls."
The pulsing began again, making Thor cry out. It was certainly more intense than anything he had previously experienced.
"Good?"
"Mmm-hmm. But how do you... Is it good for you?"
"Oh, yes. You are so warm inside. And you are already beginning to clench. It's delicious."
"I can make that happen faster."
Thor lay back again to gain access to where his cock was just beginning to leak against his stomach. He wrapped his hand around it, stroking in a way he had so many times before, knowing that on the fourth or fifth action he would feel the answering twitch in his cunt right...
There.
"Ah!"
And if that wasn't the most beautiful sound he'd ever heard. Something he would very much like to hear every day of his life.
"Oh, Thor, do that again."
It was as though their bodies were in sync, his muscles contracting as Loki's cock expanded, creating an unbearable tightness between them.
And Thor had an idea.
He carefully planted his feet on the bed and pushed solidly upwards.
Loki cried out, and Thor felt it, a distinct hard swelling at the very base of his cock.
He'd done that. It was him making Loki climax. So he repeated the action until he felt Loki making little thrusts into him, the pulsing of his cock increasing to almost unbearable levels.
"I need you to come, Thor. Spill before I knot you."
He was amazed he'd lasted this long to be honest, and the touch of one of Loki's hands on his cock was enough to have him gasping out and spattering come on both their fingers, his cunt clenching tighter than ever.
And now he really felt it, something plugging them together as Loki fell forwards into his arms, letting out intoxicating little cries and locking his lips with Thor's as the pulses of his cock subsided to gentle twitches.
"Was it...?" he asked between kisses. "Did you enjoy it?"
"Of course. It wasn't quite as I imagined it would be, but no less pleasurable for that."
Loki hummed happily against his chest, nuzzling against him as inside Thor could feel him gently spilling, not in the fast rush he was used to, but in an almost lazy manner.
"So...how long before your knot deflates?"
"Hmm? Ssh. Go to sleep now."
"Loki, how long?"
"Not long. Maybe twelve hours at most."
"Twelve hours?!"
Loki laughed.
"Relax, husband. I'm joking."
"Thank the Norns."
"It's more like three."
Thor sighed and wrapped his arms around Loki's back. At least he wasn't a heavy burden to hold.
