>>31969881I'm not the anon who originally requested this but I thought it was a fun idea so here's my best recollection of the prompt which I cant find in the archive now:
Suisei asks you to explain what kissing is and demands you teach her about kissing first hand. Suisei hates you, but she slowly becomes addicted to kissing you and develops a fetish for mouth bacteria exchange after doing research to understand it better.
Has a reverse Girlfriend X vibe to it. If someone can point me to the original prompt I'll forward it to the prompt archive.
