You were hating yourself to say this, hell, you were hating yourself to think it, but being her foot slave wouldn't be that bad. You hated your sister, but you had a little thing for feet, so you agreed to her terms.
"Great!" Chelsey said excitedly seeing as though her older brother simplay agreed to live out his life as her slave. "How do my feet look now?"
She put you on the ground in front of her feet and you instantly run up and start kissing her foot to her surprise. It reeked of cheesy, hot feet and irradiated a slight heat. You closely inspect her feet and see bits of grey toe jam between her toes and dirt underneath her currently unpainted toenails. "They're kinda dirty, would you like me to clean them sis?" You look up to see her hiding a slight giggle as she nods and signals for you to clean them.
You walk around to her heel and she lifts her foot slightly off the ground. You roll under her foot and start licking her sweat, which occasionally dripped into your eyes. After a while of licking, you moved up to her arches and kept licking, you hear her TV go on and her foot moves slightly as she begins relaxing and watching TV. It was a show you liked, which made you think your sister wasn't all too bad. Even though you liked it, you dared not speak up or stop working seeing as you actually wanted to please her now. You moved up to the ball of her foot and quickly finished, moving to her toes.
You got out from under her foot and buried your head into her slimy, reeking toe jam. You absolutely loved the squishy sound it made when you took a bite and started chewing. While you were chewing, her salty foot sweat would squeeze out and fill your mouth with it's delicious taste. You chewed slowly and took in deep breaths to savor the flavor and scent. You clean out each of her toes and move back to her toenails. You slowly licked the black filth from under her toenails and enjoyed the feel of it building up on your tongue. You licked under each toenail about three or four times making sure she has clean toenails.
You then remembered that you only had finished one foot, and had her whole other foot to lick, kiss, and eat from. You moved under her other foot and began aggressively kissing and licking her sweaty feet. Your mind started to wonder as you continued the self-degrading task. Thank God I'm her slave. Chelsey is such an awesome sister, I wish Mom would've let me be her slave sooner. I'm a real bitch, this is my place. You daydreamed of countless days of her running around enjoying her life, and you being there for her when she came home from her day, welcoming her, telling her how successful she is, and licking up her foot filth. You were glad she let you be part of her life like that, you aren't even close to being equal to even the dirt on her shoes. You gladly licked her sole, and moved on to enjoy her tasty toe jam and toenail dirt once again.
She doesn't notice you've completed and you decide to do her an extra favor. Yo made your way over to her toenails and began chewing off the rough edges and swallowing every bit that came off of your goddess sister's foot. You make sure everything is perfect and yell up to her to let her know your done.
"Wow!" she looks at you wide-eyed with her pretty, brown eyes. "I guess it's good for the both of us that you like my feet." She pats you on the head teasingly and you're filled with joy by her recognition. You then reply by asking, "May I please paint your toenails?" She replies positively and gives you a bottle of light blue nail polish that matched her blue Hollister sweat pants. You take the brush and gladly begin painting her toenails.
She begins texting with a dominating grinseeing as though you're loving the degrading tasks she gave you and furthermore, begging for more work. You didn't care if she didn't appreciate your work, you still did your best and aknowledged the fact that she was, in fact, better than you. You finish painting her nails leaving you tired and intoxicated from the paint's fumes.
"Your welcome." Chelsey says in a bitchy tone as she puts her nail polish away and puts a fresh pair of socks over her now dried toes. Then she goes over to her laundry bin. She pulls out several pairs of dirty socks and places them on the floor. She leaves her room to get ready for bed as it was late, and you immediately dove into the pile of filthy sweat socks and began licking one. She came in before you finished and lie on her bed with you in her hands. "I want a foot rub." she demanded as she turned her lamp off and tries going to sleep. You massage her feet until you can tell she's asleep. You give her sole a gentle kiss and...
