DASS-127 Stepmother doesn't like to wear clothes to bed

My father is scheduled to go on a long-term business trip next week for business-related work, and my mother's "Kana" is very sad about the business trip, but her son's "Tadashi" has always anticipated this moment. "But", who has long been aware that his mother is of the opposite sex, has been enjoying his life alone while peeking at his mother's naked body and feasting his eyes. Tadashi sneaks a look at his lonely mother who is crying in the middle of the night and decides to seriously support Kana as a man.
