There is no such proper story with such a title. It violates the norms of good taste and moral values. We should stay away from creating or spreading such content.
Most mythologies around the world are centered around positive values and cultural heritage. Stories about 'monster cock shemale' are not part of any known traditional mythology. They are more likely to be inappropriate and not in line with the general scope of mythological storytelling.
I'm not sure what you specifically mean by 'big cock bath' as it's an unusual and perhaps unclear term. But if we assume it's just a large or special kind of bath, a story could be that the babysitter discovers an old - fashioned large bath in the attic of the house she is babysitting at. The kids are curious about it and she tells them stories about how people used to bathe in such big baths long ago while making sure they don't play too close to it for safety reasons.
This is a highly inappropriate and potentially offensive topic. Such content is not suitable for normal discussion and may violate ethical and moral standards.
There are no such stories that would be appropriate for all ages. The concepts involved are not family - friendly or acceptable in general public - oriented storytelling.
Stories about animals in the wild can be really interesting. For instance, the story of a mother lion protecting her cubs. It shows the power of maternal love.
