I have read Kyara story. Kyara is current China.
The Kyara story is a collection of short stories written in Japan in about 1187.The contents are love.
One of the stories has the story of the woman who had make love with a male dog. She refused the marriage that the parent decided and lived in the seclusion with a woman attendant.
The woman attendant loved the dog which came to the garden, but became the sexual relationship gradually.
The hostess to see it became unbearable and invited a dog into the bed.
Similar story is seen in various places.
There is the genre called bestiality in a porn site.There are a lot of movies to appear of a woman and the dog.There is the porn of the feeling that an amateur made at home in that.
I am made to think crossbreeding of a primitive era.
Whenever I watch a big dog and a woman walkies, I remind the story.
