I am a huge fan of Project Hail Mary (it’s about a human and 5-legged crab like alien who meet in space and become friends while trying to save their worlds), so I started reading online PHM fan fiction. So much of it is about the human and alien falling in love, consummating their love and even producing children together, none of which happens in the actual story. Much of it also includes graphic drawings. I just finished reading one where the human fertilises the alien’s egg and now they are waiting for it to hatch, looking forward to being parents together. Others are about the alien, the alien’s mate and the human becoming a throuple. Just thought I’d share as it is quite entertaining. Does anyone know any other good fan fic series?
