After the punishment your sister put you through, she's feeling kinda bad. She is dressed in her school uniform and sweaty socks and wants to make your junk feel a lot better. She knows you love her sweaty soles as she takes off her socks and exposes those perfect size 7 pink soles. She rubs your crotch through your pants and notices how hard you have become! She tells you she will give you a nice footjob to make up for it all. She poses a bit at first for you then gets down and removes your pants. She rubs your aching cock and lathers it up with lube then starts expertly stroking your cock. You are rock hard the entire time as she giggles at how much you throb between her soft soles. She rubs her soles over your shaft and head then strokes up and down again,you can barely hold back before unleashing a MONSTER cumshot everywhere much to the delight of your sis!
