You feel such a strong attraction to the blue fox, particularly her ass, as you walk closer. Her tight pucker seems to flex slightly as you rub over it. You catch a slight whiff of fox crap, but strangely it doesn't seem to bother you!
Krystal lets out a soft purr as you rub her rumphole, and as a loud, ominous gurgle erupts from inside, you notice she starts to paw off right in front of you!
