Czech Soles - Sofie's feet are so dirty from walking barefoot

Sofie is member of a barefoot walking club, she believes walking barefoot outside is a very healthy. Maybe so but it has some disadvantages - for one her feet are usually very dirty and when she comes home like this she usually makes mess at home too. But there is one person n her life who always encouraged her to walk barefoot - you, her rommate. You don't know if she knows this about you - that you love dirty feet and that you would like the most to lick her feet clean and today it seems that she might know your secret after all. As she arrives Sofie stars to talk about her dirty feet and shows them to you but she's no taking a shower, she's not washing her feet, she's just showing them to you up close and describing how dirty they are to you. You're not complaining and it seems to make her happy, it seems she knows about your little secret after all. Instead of washing her dirty feet she rests on the sofa, moving her feet up and down and up and down, making you so horny. What you're gonna do?
