During my wife's pregnancy, even masturbation was forbidden. Kana Mito

To support my pregnant wife, my mother-in-law Kana came to Tokyo half a month ago. Thanks to Mr. Kana, I thought that housework would be easier and my wife would be in a better mood, but the wind hits more than before, and I am furious with me who comforts myself alone and is handed down a masturbation ban. A few days after that, Kana-san, who was listening to our quarrel, said that her sexual desire would not subside and she was frustrated. I was on the verge of overflowing libido, so I asked for Kana-san with the excuse that it was only once.
