You're spending a quiet Saturday afternoon playing video games with your little nerdy step-sister, but you're getting bored. You tell her you've got plans, but not for a while and ask that you just chill for a bit and offer her a foot massage... but her feet are pretty dirty and they look so good. She teases you about liking her feet and dares you to lick them... so you do, and you love it! Before you know it, you're stroking your dick to your step-sister's sexy feet and cumming all over her cute, long, painted toes and feet and licking off your own cum off of her delicious feet...
