Mr. and Mrs. Ninomiya have been married for a few years now, but both are still very happy and have never had any arguments or conflicts in the family. The reason they maintain their happiness undoubtedly includes making love, which has become a routine for the husband every morning before going to work. Continuously using his hands to help his wife find pleasure and then expending a lot of energy on their daily intimacies, he remains very cheerful about it because it is the key factor that brings their family closer together.
