Sierra likes to keep herself in good physical shape, so she likes working out a lot since she is a model, so she spent about 60 minutes sweating it out on the stationary bike! She really thought it would be a good idea to show her slave how sweaty her feet could get after a long workout like that, so she brings him into the room, and gets him on his knees so he serves him as a good slave! She makes him take her sneakers off, then completely covers his face with her sweaty gray socks! They were all wet with sweat, so she enjoys rubbing them all over his face, and makes him take deep breaths in her socks! She makes him sniff her sweaty gray socks, and makes him lick the sweaty bottom of her socks too! Sierra also makes her slave to sniff the insides of her sneakers deeply, before asking him to take her socks off, so she can make him sniff her sweaty bare feet! Her feet smelled really bad after riding the stationary bike for 60 minutes, but she just loves rubbing them all over his face, and making him lick the bottoms of her feet too! Sierra also makes him lick her cute little toes, just to make sure theyÂ’re cleaned up! Sierra is such a demanding woman!
