Reiko Yukawa, 53. Her son, Tatsuya, remains a constant baby. Every night, he comes over to sleep with her, sharing the same futon. However, recently, he has been touching my breasts. At first, she thought it was her imagination, but with each passing day, his touches have become more and more obscene, and he has begun to touch her sensitive parts. She has been feeling lonely because her husband is away on a business trip.
