## Description
A world where cumming buckets is more important than academic abilities.
Not only is it okay for sons to fuck their mothers; it's seen as a sign of utmost love and respect.
Here, women will treat your phimosis with their mouths.

In town, at school, at home; people are having sex everywhere.
There are semen fundraisers for childless couples and special train seats for impregnation intercourse,
as well as educational shows on how to inseminate your mom airing on TV.
Here, boys kiss their moms on the cervix.

This is the story of my and my mom's daily life in this world.
