Please note - this story uses characters from mythology and not those that you may have seen elsewhere. Any co-incidence is of course just that. I like to imagine that it happens in an alternate universe.

"Asshole. Asshole. Asshole. Asshole."
"What's up sis? Your new boyfriend have a fixation with your asshole or something?" Thor grinned at Hera. His sister was obviously annoyed about something and the least he could do was to wind her up a little bit more. That is what brothers are for.
"No." She scowled. "He IS an asshole. All Earth men are." Hera sank down onto her bed, her head in her hands. Despite being a couple of hundred years old she still looked eighteen, acted eighteen, and seemed to have the emotional stability of an eighteen year old.
"Why, what happened?" Thor said, sitting down on the bed next to her. They could still only afford a small apartment in New York City here on Earth. Despite being Gods work was hard to come by, and they kept getting sacked when they turned up late for work. Saving the planet had it's downsides, like unexplained absences and arriving at ten past nine covered in blood. Normally someone else's blood.
"I'm beginning to think it's a problem that will only be solved when we get off this godforsaken planet." Hera sighed, looking her brother in the eyes. "Earth guys just don't cut it. They're good for maybe an hour or two tops. The very best can go maybe eight. How is a girl supposed to last on just eight hours?"
"Eight hours?" Thor looked blankly. He had no idea what she was talking about. "He took you on an eight hour date?"
"No, stupid." She slapped him on one of his powerful biceps. "He was only good for eight hours in the sack. Making the beast with two backs. Shaking of the sheets. In the service of Venus... Oh for fuck's sake Thor - Eight hours pounding my pussy."
"Oh." Thor blushed. "That. Only eight hours?"
"I mean I don't expect much but the guys back on Asgard..."
"We can go twenty four, then twenty four the other way?" Thor grinned. He himself had managed a full week once, and only stopped because of some invasion or other. He'd gone out and cracked a few hundred heads and then gone right back to fucking. "We Asgardians do love to fuck."
"We do." His sister said. "Here I'd need to fuck a football team just to get started."
"Fifty three at half an hour... you'd be right." Thor nodded.
"I'm not about to start doing that. Someone would talk." Hera pouted. She was a very pretty thing. Long dark hair that reached her thin yet muscular waist, dark eyes that made all sorts of delicious promises, long legs, a curvy butt, and boobs so firm she could use them to knock out enemies. Thor thought he'd seen her do that once or twice.
"Yes, seems like you have quite a problem on your hands." Thor patted her on the thigh. "Maybe that's the solution."
"My hands? You want me to wank?" Hera rolled her eyes. "Doesn't do it for me brother. Besides we have to share this small room and I don't want to have to use the bathroom to do it in. You or dad will need to pee eventually and you'll disturb me."
"You could... wank... in... here?" Thor said haltingly.
"But we share a room!" Hera sighed.
"I don't mind." Thor shrugged. "We're brother and sister, but we're Asgardians. Back home we'd both go to the same orgies. Do you remember? Our eighteenth..."
"Oh yeah." Hera giggled. "Remember when Sunna was trying to get us to fuck? And we eventually had to explain to her that we're brother and sister?"
"And she said we should go for it anyway!" Thor laughed. "Apparently it's an old custom. Or so she said."
"I'm glad we didn't."
"Me... erm... too." He blushed and turned away. As soon as they had started talking about fucking Thor's eyes had been draw to Hera's thick, soft, wet lips as her tongue worked behind them. He loved her mouth. It looked so soft and giving.
"Wow. You don't sound so sure. Do you really mean it's okay if I wank in here?" Hera asked him. She stood, placing her hand on his flexed bicep.
"Sure. Just keep the noise down. I promise not to stare." He winked. His defense was always attack.
"Meh. Look if you like. I'm not about to keep the noise down either. I'm not sure that I can." Hera flicked her hair. "It'll be a long time too. Hey - do you mind if I use toys?"
"Toys?" Thor blinked.
"Sure. It's fine using my fingers but I like something inside me while I'm doing it. Otherwise my pussy and asshole get lonely. Not to mention my mouth." As he watched she licked her lips. He swallowed hard. His cock twitched in his pants. Just thinking about his beautiful sister Hera, who was by her very nature a goddess, beating herself off constantly for a whole day made his blood rush through his veins. He too had a problem with Earth. He had tried fucking the women for a whole day, but most of them were happy after a couple hours. They broke up with him more often than not. They said he was "unnatural". What could be more natural than a God? Still, he knew that his manhood was rather large, and that Earth men could only cum a couple of times per day maximum. Asgardians could regenerate every ten minutes. Filling their partners with thick creamy cum was one of the parts of Asgard sex. It was like extra lubricant.
"Toys are fine I guess. I'll try and stay out of your way."
"I'll think about it then." Hera said. "Thanks big brother!"
She threw herself against him in a hug. Thor loved it when she hugged him. Her firm Asgardian body against his, her tits against his muscles, her scent in his nostrils. Plus she liked to push her hips forwards when she hugged. That way she rubbed against his crotch. Normally he was soft, but half hard it felt even better. He knew she could feel his cock against her.
"Maybe you should wank too brother. Feels like you have a problem going on down there. If you don't attend to it your suit will never fit."
He laughed. "Too true sister."
Hera did not consider it too long. In fact when he woke up the next morning she was already at it. The light was streaming in through the window of the bedroom they shared, and Thor could hear the soft wet sounds of female masturbation. She was breathing hard, moaning loudly, her words totally evil as she whispered them.
"Uh. Oh fuck yeah! Gods my pussy is wet. I need it fucked. Fucked I tell you!" She was hissing as she spoke. Thor figured she was already a couple hours into this. The room smelled of pussy juice and lube. There was a soft buzzing and he knew she must be using one of those "toys" that she talked of. He tried not to look but his eyes were drawn to his sister's bed.
What a view he got! Hera was up on her hands and knees, ass in the air, balancing on her knees and the crown of her head. Her hands were between her legs, one pushing a large, thick, fake cock into her upturned pussy. The other hand was playing with the nub of her clit, just visible between her thighs. Unlike Earthers Asgard women had big thick clits that were a couple of inches in length. They were like mini cocks, jutting obscenely from between their muscular thighs. Thor so missed the feeling of an Asgardian clit rubbing on the shaft of his cock as he fucked into a warm wet hole. Earth women were tight but he missed the extra sensation.
He lay and watched his sister. There was nothing else to do. She was the whole show. She had all his attention. She was naked and as she fucked herself her firm boobs shook with each stroke. Her muscles were long and muscular, those of a warrior. She had tattoos on her back that squirmed as she waved her butt in the air. Thor felt himself grow hard. He kept the sheets over himself and adjusted his cock. Damn was his sister putting on a hot show. It was so long since he'd seen a Goddess in action. He had forgotten how sexy, how enticing, how lewd an Asgardian woman could be.
Even if that woman was his own sister.
He wondered about the old customs. Asgardians had once rutted with anyone. Mothers with sons was a particular favorite in the legends, but there were plenty of fathers with daughters, sisters with sisters... and brothers with brothers. In his half awake, fully aroused state he was recalling the legends of brothers with sisters. Until now he had only been able to think of them in an academic way. This morning it was pure lust that drove him.
"Damn, Hera, shit." He thought. It had been too long. Too long without an Asgardian woman or two or three. Thor loved multiple combinations but right now he could only think of one. To his own shock he found that he had wrapped his own strong hand around the thickness of his dick. His other hand was moving to join it. He wrapped them around it, holding it like a two handed sword, his fingers wrapping around his shaft one after another with his head still uncovered. Thor enjoyed the fact that he could take a two handed grip of his weapon and still leave more swelling out. He was hung even for one of his people.
As he held his cock he watched his sister. Her masturbation was like a kind of dance. She moved her hips in big slow circles as she jammed the fake dick into her sloshing twat and masturbated her nice big clit. Cum ran down her thighs, sometimes splattering in droplets onto the bed covers. Asgard women could jet too, firing cum from their pussies like piss. Many was the time that Thor had ended up covered in the stuff from head to toe.
Thor could not help it. He get his cock a little jerk. It felt so good! He felt wrong to be handling himself while watching Hera. She was his sister. The old customs were gone. She looked over at him. She smiled, and winked.
"Morning... ahhhh fuck... brother!"
"Morning Hera." He tried to sound nonchalant. He was not sure it worked.
"Enjoying the show?" She teased him, her voice thick with emotion and cracking with passion.
"I could hardly miss it. You're not exactly hiding."
"Once I get going there's very little hiding it." She laughed. "I just can't stop my... uuuuuhhhh... self."
As he watched she lay down on her side. She faced him across the room. Her upper leg was draw up, bent at the knee, her thigh muscle flexing. The other leg lay down but was also bent. He could see everything. The curl of her muscles, the small patch of hair at the top of her pussy, her cunt lips pulled back around the shaft of the toy. She was strumming her clit like it was a small musical instrument. He skin was slick with her own wet and sticky juices.
"I'm not asking you to. It's... interesting to see you do it."
"Inter... nnnghhh... interesting?" Hera moaned. "I'm not some science experiment Thor. I'm... ahhh... your sister and an Asgardian warrior. And a woman."
