Stepsister's smelly bare feet worship

Nela has a stepbrother who is a total perv. He likes feet and he likes the most when they are smelly and sweaty and when he can smell them and worship them...it's like having a pet :). She knows all this about him and so far they kept it a secret before their parents. Nela is taking street dancing lessons and she has just got back from one. Her feet are sweaty and sore and she's tired. You know what would be great right now? A foot massage. She learned how to use her stepbrother's perversity for her own purposes - she calls for him and asks whether he would give her a foot massage. Of course he agrees and start with it without hesitation. But instead of massaging her feet he would much rather smell them and have them in his face. OK than, if Nela will get her foot massage after than it's fine. He can do with her feet whatever he wants. It's on! Once again he has a chance of playing with his stepsister's feet. Awesome! Nela and him did this several times already but...
