After work, when no one should be there, I hear moaning voices! My new job is company security. While I was looking around the office alone, I discovered a tempting office lady masturbating with a toy! I thought it would be dangerous if I was found out to be secretly peeking, but the office lady, who had turned the stress of overtime into sexual desire, asked for my dick! The sound of a violent blowjob and moaning voices echoed through the quiet office at night!
