If I look at my mother's breast. Mikumo Yuriko

"I can't stand it!" Yuriko (Yasuko mikumo) was desperately resistant to her son who cried so much. I noticed that the appearance of the son was funny from that time when I was taking a bath. But I want my mother to be here. There is no way to resist the strength of the son who grew up to the adult body, and Yuriko abandons the resistance and makes a suggestion if it goes over the line. "My mother teaches me how to treat women", so the sex education for momoko's son started.
