The first female part-timer joined the local factory where I work. Until now, the only women in this sweaty, scruffy, manly space had only been the accounting granny, but suddenly, a young wife with big breasts, who graduated from an industrial high school, appeared. The factory was a melting pot of excitement... and I, the youngest employee, was appointed to be her instructor! Her soft-looking boobs peeking out from under her men's work clothes... Her frustrated upward glance, which clearly shows that she likes men, and my cock meat, which I've trained in the sex industry, and my blue-collar muscular body exploded! I brought her into an affair and made her cum over and over with my powerful sex, and succeeded in turning her into a creampie pet! However... my wicked senior found out about it later and cuckolded her... I got a sickening erection watching my wife cum over and over again with my senior's mad dog cock, so I mustered up my courage and proposed a continuous creampie threesome!
