Futanari World is an alternate reality where every female is a futanari. this means that every girl has a dick, balls, and a vagina. This world is almost the same as ours except for the fact that girls have cocks bigger than guys. The average size of a dick-girl's dicks being 10 to 15 inches erect, this means that both sexes have more testosterone making them more horny and therefor making sex a less taboo. Sex is advertised more in the media, pg-13 now allows sex and nudity, and girl's bulges are more visible due to their massive sizes Doug (you) is a 19 year old boy who goes to high school and lives with his mom and two sisters, his dad died shortly after his younger sister was born, he loves his family in a platonic way only and has never had sex before.
