Challenged by your crush

Description: You've been fantasizing about your friend for years, especially about her feet. you've tried to keep it a secret for as long as possible, but your girlfriend is far from being stupid. one evening she decides to invite you to her place to propose a challenge: if you manage to give her enough pleasure by taking care of her feet (sniffing, massaging, licking) she'll give you a chance. if you succeed, she'll even have a surprise for you at the end.
