Saitama comes home to find Genos after an...odd repair session.
After the initial panic and confusion, the young cyborg coaxes him into a calm discussion about what happened and what the new body means to him.
After a while of letting the idea ruminate, Saitama decides to shove his confusion aside and embrace the new Genos.
The problem? Not everything or everyone is as it seems.
--or--
Genos gets transferred to a female body and Saitama is understanding but Genos isn't really Genos.
There aren't enough Genos x reader fanfics. BUT TOGETHER WE CAN UNITE OUR LOVE FOR THIS TOASTER TOGETHER IN THE NAME OF FANFICTION ( •̀ᄇ• ́)ﻭ✧
So I humbly offer up my sacrifice to the fandom with this idea kind of blossomed into a story.
