This is a story I've just not been able to put down. It keeps popping into my head every night when I go to bed.

Two dickgirl astronauts crash their ship on a jungle planet. On said planet, there are crystals that glow once a week when one of the planet's moons in a nonsynchronous orbit aligns above them in the sky. Those crystals vibrate at a frequency that prime the human libido, unbeknownst to our stranded astronauts. The local lizard dickgirls do know and have a weekly sexual ritual to stay normalized. They will need to "inform" our astronauts how to survive on this very...sexual planet.
