Yes indeed! Three of my favourites for SU, though in no particular order, are Prolusion, Pass Around, and In which Pearl discovers sometimes Amethyst is right.
Prolusion is Pearlrose gem egg hell without the oviposition, and it’s a totally great story found here.
Pass Around is Lapidot/Jaspidot with both of them sharing her (I think?) and it’s heavy gem egg hell and I actually got sick reading chapter three because I can’t do cannibalism but I really wanted to read it, and I’m currently not sure where to link? Mlgspacedorito wrote it though, and it’s great! Wish I knew where to find it though. EDIT: Pass Around can be found here.
In which Pearl discovers sometimes Amethyst is right is just like, one chapter of a two chapter fic right now, but I have never laughed so much during a smut fic before it gets to the smut. No smut in it yet, though. Found here.
