My female boss, Komatsu-san, is cool, tall and beautiful. She is an office lady who is devoted to studying sperm even during work hours. "Why does a penis get erect?" "What can I do to ejaculate a lot?" With a pure desire to study, I, her subordinate, am used as an ejaculation doll and played with in the office! As I continued to ejaculate unfruitfully in my research, Komatsu-san finally invited me to ejaculate lovingly, saying, "I heard that kissing makes ejaculation better." My penis, which was subjected to ejaculation experiments every day, has been promoted to the object of Komatsu-san's sexual desire! The forced ejaculation office with my female boss, which started as an experimental mating, has become an adult erotic SEX office where our lips and bodies are intertwined!
