You and your coworker go to hook up, but after seeing your strange cock, she decides you'll actually be doing things her way, lest she tell everyone about your... situation. Instead, she has you pledge to worship her, stroking to her body especially her ass. After your orgasm is out of the way though, you'll be responsible for getting her off by pleasuring her with your mouth. You agree and she leads you through stroking and cumming to her ass. Nobody else would be using your cock anyways. In part 2, it's your turn to please her.
