One Punch Man Genderbend One Shot
The fanfiction where Saitama and Sonic are female but Genos is male. It’s my fanfic so they’ll be OOC where it fits.
Saitama was glad the supermarket in Z-City was doing a buy 10 pack and get 2 free packs of sanitary pads this week. She was down to her last three pads and was eager for this sale. She only bought pads twice a year, though sometimes she did join the boxing day crowd to stock pads for next year’s supply. She didn’t like wearing tampons because she was unused to the feeling of something inside. Yes, Saitama was a virgin but that didn’t matter in the scheme of things. What mattered was how to manage it while fighting monsters and mad men. Saitama was lucky, that she was not sensitive to the factory produced sanitary pads. She never had to use a cloth pad like an unfortunate lady ninja.
Sonic was hanging her cloth pads out to dry. Sometimes she grumbled about the monthly washing and drying but since her body was sensitive to mass produced pads she just had to bear with it. Despite her grumblings, she was glad that it was au natural and she even used simple soap to wash it. Money pinching technique indeed. The first year she wore a commercial pad, her lady bits would itch and she had to suppress the need to scratch down there, all while defending a client from a squid monster. Afterwards, she went straight to a cloth shop and sew her own cloth pad.
Genos didn’t have to wear a pad, he was pleased of that fact. The biology textbook he was processing was a standard government issued one and so didn’t include the gory realistic bits of pads, a reality for Saitama and Sonic each month. There were a lot of knowledge unknown to Genos, and he was keen to absorb everything. Even the unnecessary ones like female menstrual. He was nineteen and though his body a replica of a mature twenty something male human, inside he was immature as his brain was still a biological organ. A few years ago a kind robot doctor kindly taken him in and replaced his dying human body with cyborg parts.
Genos placed the book neatly back on his good doctor’s shelf. Suddenly his phone blared the ringtone he had set for the Hero’s Association. Knowing that his book browsing session would be replaced by some villain punching session, Genos started running out of the simple home using his cyber speed.
