In a single parent family, mother took much care of son, whatever son's clothing, meal and school life. Mother loved her son very much, but the love grew fast and turned from caring to sexual love.

Mother suppressed her impulse by masturbating with her son's clothing. " I can't have sex with my son, my dear son!" However, one thing was out of mother's expectation, which was the arrival of her son's puberty. Mother was surprised and happy that her son was interested on female body, especially those mature women just like her!

"It is not enough for my son to learn sex and female with only my clothes!" thought by mother, "I must help him to have a better understanding on sex and women! But what should I do...." " Oh YES!!"

On the next day, son woke up. When he moved to the living room, he discovered a message left by his mum. "Son, I think it is time for you to have some healthy sex education to learn more about knowledge of sex and the difference between male and female body. P.S. A sex-droid is ordered and reached our home, it places in your room, you may have a look on it. mum"

When son opened the door, he was shocked, the sex-droid was so detailed that just like a real woman, more important was that, she looked like his mum! She could even follow all the command raised! Son was very excited and started his 'sex education'
