You have to...

Your curiosity gets the best of you. You glance over your shoulder. Behind you, you see a woman who doubtlessly took great care of herself before she was Infected… an MP3 player is strapped to her arm, and the remnants of a sports bra support but poorly conceal her round, impressive breasts. Her well-toned stomach is likely little changed since she became infected, exposed by the running outfit she donned the morning before her transformation. Probably out jogging when she was caught, you think. She must have been an Infected for some time, probably one of the first. You see the enormous dangling cock between her legs, framed by the remnants of shredded yoga pants, slowly swelling to attention as she bolts after you, her worn and dirty sneakers scraping against the pavement as she frantically runs for you, wanting to use you for her relief.
