Two office girls are shocked when Bob from accounts walks in

Two office girls are shocked when Bob from accounts walks in doing a sponsored nude day in aid of prostate cancer. After they stop laughing the girls decide to have some fun with him and offer 20 if he flashes them his cock. He does it for the charity but they then offer more money if they can take pictures of him naked. Then more money if they can have a feel! He gets all the cash they have if they are allowed to make him cum and he soon shoots a massive load all over their desk!
