During exam season, my sons were busy and my husband was constantly away on business trips. One day, while I was masturbating alone, I suddenly felt my son's gaze on my back. That night, we took a bath together for the first time in a while, chatting as I washed his back. Suddenly, my son couldn't hold back anymore—his cock became rock hard and he looked like it hurt. I gently stroked him, soothing his feelings as much as I could.
