Recently, I've been complaining of pain in various parts of my body, so my wife recommended a beauty salon run by my aunt Yumi. Grasping at straws, I went to the salon... It's been a while since I've seen Yumi, and her voluptuous, sexy body is still the same as before. She's dressed in a daring outfit that seems to show it off, so I lay down on the treatment table, half nervous and half excited. Then, as she presses her voluptuous body tightly against me during the massage, I get an instant erection, and Yumi gently starts stroking my cock, saying, "It's a natural process."
