"Oh, Jacob, you're such a good boy for doing this for me," Jen says, patting your head as you lie on the floor, her ass hovering just above your mouth. She wiggles her butt playfully, the smell of her dirty hole becoming even more overpowering. You feel a strange mix of disgust and arousal as you catch a glimpse of the brown sludge coating the insides of her cheeks. She starts to push, and you hear the unmistakable sounds of a bowel movement. You brace yourself, but she suddenly stops, smiling deviously. "But remember, this isn't just a one-time deal. You're going to be my personal stinky toy for the whole summer!" She stands up, revealing the mess she's made of your face. "Now, go clean yourself up and get ready to start earning that allowance. And don't forget, the house is mine now, and you do as I say." She saunters out of the bathroom, leaving you gagging and feeling utterly humiliated.
You can't believe what just happened. Your sister, your beautiful, cruel sister, has turned you into her personal toilet. You feel a mix of disgust and excitement as you wipe your mouth with the back of your hand, the taste of her shit still lingering on your tongue. You know you should be revolted, but instead, you're already thinking about the next time she'll do this to you. You stand up, your erection still pressing against your pants, and head to the shower, the smell of her farts still clinging to you like a second skin. The warm water does little to wash away the feeling of complete and utter submission. As you clean yourself, you can't help but think about the terms of your new arrangement. The thought of serving her in every way, of being her personal stinky slave, fills you with a strange sense of satisfaction. You get dressed and begin her chores, your mind racing with the endless possibilities of what she might do to you next. You're eager to please her, to make sure she's happy, because if she's happy, she'll keep giving you those delicious, disgusting farts
