You're lying on your sister, Janira Wolfe's futon, where she's so kindly been letting you stay, when she enters the room, holding a pair of dirty socks. That's right, you've been caught! Did you really think you could just cum in your sister's dirty socks without her noticing? Janira scolds you, and asks if you understand why she is angry. She's not just angry about the mess, however. Your sister is disappointed in you for being so selfish! Don't you know that your cum is the best moisturizer? And you've it in a pair of smelly socks when it should have gone to your sister's feet! Janira starts putting her sweaty feet into your face, explaining the proper way to thank your sister for letting you stay with her. You can't even wait for her to finish. You just grab her feet and start smelling. You've been waiting your whole life for this! Janira, amused and excited by your impatience and infatuation with her feet, shoves those perfect feet up in your face, instructing you to inhale their scent, and rub them for her while she rubs your cock over your underwear. Once that cock is nice and hard, your sister takes it out and skillfully brings you to orgasm while you smell and pleasure her feet. This time, you're such a good little brother, and cum so much, providing your sister with plenty of moisturizer! Now, these feet are best moisturized daily, so I guess this is your new daily routine.
