grocky is really good because they dont really want to Have Sex with each other as much as they want to sort of crawl into each others insides and live there forever .
weird notsex but definitely horny activity they do is rocky makes grace watch thriller or scary movies so he can be a pervert about the sound of graces heart and lungs going fucking crazy and being very Viscerally alive next to him in a controlled environment. he constantly complains about how sloshy and wet grace is all the time but privately he is so deeply traumatized and he needs to be glued to this guys obscenely exposed heartbeat and rushing blood noises at all times
also something somethinng the eridian equivalent of a vibrator being a tuning fork and they. experiment . with that. its not necessarily Sexual stimulation it doesnt really engage the reproductive organs but it DOES very much engage the pleasure sensors in their crystalbrains and involves a disgusting amount of trust because if something is resonating Directly against their carapace loud enough theyre functionally blind. grace then tries hooking it up to the frequencies of wonderwall and loses all privilages forever
anyway. i love when two characters love each other so so much in such a complicated way that they dont have sex but instead do something MUCH weirder
THEYRE SO GODDAMN WEIRD!!!!!!!
