IENF-442 Male and female colleagues at work try a slippery, intimate oil massage during their work break!

We approached a man and woman who looked like office workers walking down the street and told them they were participating in the filming of a variety show where they could win a prize if they completed the challenge. They said they are usually reliable work partners and have never thought of each other as members of the opposite sex. The challenge was: if the man didn't get an erection during a close, slippery oil massage with bare crotch, he would win 100,000 yen. If he ejaculated during the bare crotch massage, he would win 1,000,000 yen! What will happen?
