Someone pls help me find this fic. It’s been a few years since I last read it so it might not be 100% accurate but:
It’s a ratchet/drift fic where drift was in heat (I think) and ratchet helps him thru it but never really has sex with him, just helps him ease thru the heat. Only after the heat is over ratchet tries to properly court drift
I think it might be “the chemicals between us” by @iopele
