I was being bullied by the trainer at my new job and was forced to work overtime every day. One day, I was alone with my admired senior (Kano-san), who is beautiful, good at her job, and works as the head of the sales department even though she is younger than me! I got an erection when I saw her defenseless cleavage and my virginity was revealed... I couldn't resist the mischievous temptation of my senior and crossed the line. I had sex many times until the morning, experiencing the pleasure of sex for the first time.
