I don't know if this idea's been done. But it had to be.
This does not have to be interpreted as GL (Girl love). It can just be interpreted as 'friends' joking around (emphasis on the air quotes).
"So," Aphrodite said, taking a break from the extreme focus she was pouring into the task of painting her nails the perfect pink shade, "since, like, you don't go through baby-making in the traditional way, can you have a child with a girl?
Athena spat out the tea she had been drinking. "What?" she managed to choke out after she finished coughing and clearing her lungs.
"Can you have a child with-"
"I heard you the first time! I meant, what?"
Drying her painted nails with magic, Aphrodite rolled leisurely off her Roman-style lounging chair to pose in front of the flustered goddess of wisdom. "Obviously, I am gorgeous."
Biting back vomit and the urge to laugh, Athena nodded at the other woman to continue. After all, she was slightly curious about the path the Aphrodite was taking this.
"And everyone says you're smart and all, so I suppose it's true."
Athena was insulted by this, but instead of starting a bitchfight that would have brought the attention of all the male gods to them she merely stayed put, plotting a mental blueprint for a device that would cause the goddess of love immense pain. Or embarrassment. Or possibly both. Yes, both sounded rather nice. She'd get Hephaestus in it and everything.
But right now she had to pay attention to the bimbo.
"Imagine," Aphrodite made a sweeping gesture with her recently-manicured hands, magically making rainbow-tinted sparkles fly everywhere. "A demigod. A demigod with your brains and my beauty. He or she could take over the world."
"We're both gods," Athena reminded her. "Our offspring would be an immortal."
"How do you know?" Aphrodite countered. "You've never had a child with a god before, have you?"
Athena opened her mouth to counter that – and then closed it with the realization that the brainless bimbo was actually right. For once.
Wait. That meant she was wrong.
Her mood soured drastically. "Well, thank you, Aphrodite, for the tea with the aphrodisiac and the rather brain-numbing conversation filled with no actual content, but I really must get going. More important matter calling, you know." Such as planning the device that would cause the bimbo the pain and embarrassment she deserved.
With a snap of her fingers Athena transported herself out of Aphrodite's temple.
Aphrodite pouted and picked up the tea that the goddess of wisdom had only partly drunken. "I knew I should have stuck with the chocolate idea," she sniffed, tossing out the tea with the pea extract mixed in.
How they would have most likely actually acted should Aphrodite have decided to ask that fateful question.
"So, since, like, you don't go through baby-making in the traditional way, can you have a child with a girl?"
"I don't know."
"Want to try with me?"
"Absolutely not."
