I was being targeted by my trainer at my new job and suffering from power harassment, being forced to work overtime every single day. Then one day, I found myself alone with my admired senior, Kano-san, who is beautiful, competent, and works as the chief of the sales department despite being younger than me! Seeing her defenseless posture with her cleavage showing, I got an erection and my virginity was exposed... There was no way I could resist my senior's playful seduction, and we crossed the line. Overwhelmed by the pleasure of my first sexual experience, I fucked her multiple times until morning.
