My childhood friend Sae has returned to town after a long absence. It's been over twenty years since we last saw each other, and our hearts are pounding with excitement. I still remember vividly how we used to bathe together and sleep in the same bed as kids. Now that I'm over 40, I find myself yearning to have sex with her again. Sae recently divorced, moved back to her parents' home, and quit her job, leaving her with plenty of free time. I made plans to meet up with her and another mutual friend. All three of us were in the same class from first to sixth grade and even shared baths together. The bond between us childhood friends remains as strong as ever. Now, at over 40, my desire to have sex with Sae again is growing more intense by the moment.
