I know a man and a woman, and they love each other. Their love is so strong that they decide to have a son. The son is born. They give him comfort, care, affection. They give him health, education, dwelling. One day, they decide to give him a computer as a gift. They really love their son. But, when the son grows up, he throws away what their parents have done for him, logs into e-hentai and adores futanari. I don't understand this, but it's fucking sad.
