But when I try to end the relationship, she whispers to me with a devilish voice, "But I love your dick..." and we continue to be sex friends at work! 1. We don't like each other 2. Having sex when you're alone at work 3. Insert immediately, and end as soon as you're satisfied. Follow these three rules and enjoy immoral sex as much as you want!
