[DBNK-024] If I show my erect penis to my mother in the bathroom and show her how aroused I am, will she take care of me?! 4 hours (Censored)

While I was taking a shower, my mother said, "Let's take a shower together sometimes! Hehehe," so I thought she was joking and said, "Sure," and then my mother really was in the bathroom completely naked... "I'll wash your back," she said, suddenly giving me a body wash service! The son couldn't hide his erection, and the older mother noticed. What will the frustrated mother do when she sees her son's strong penis...?!
