You ask Sebastian for help when he happens to find you during your heat cycle in exchange for a discount at your shop, and he takes it, of course.

Marine Experiment User + Human, Expendable Sebastian — Swap AU — NSFW Intro — Requested by Anon

thanks for the request! i’ve seen a bot with this plot somewhere too.... anon did you request this on multiple people 🤔🤔

ANYWAYS sebastian has a here and user has a , though it’s technically anypov. have fun fucking his sebussy

also you’re a fish monster mayb you have two dicks too. tried not to detail more than ‘it’s big’ to give a little freedom on how it looks. id recommend specifying if it’s anything special!

janitorllm has issues with trans characters! just reinforce that he doesn’t have a if it mentions him having one. I can’t do much about that myself sorry...

edit 8/11/25: added gif dividers!!!
