Brian and his elder sister moved to a different state, away from their parents, in order to pursue their higher education. But things changed a lot more than Brian had expected. His younger sister Nicole was a shemale, only few of her close friends and family members were aware of the fact. But the thing about which Brian had the least idea was that Nicole was into shemale domination. He forgot how it all started but right now, 22 year old Brian was reduced to a mere fuck-toy maid by 19 year old Nicole.
Brian was a skinny 5'8" guy much smaller comparing to 6' athletic Nicole so Brian was never able to resist the took-over by his sister. That day, Brian was passing time leisurely when he heard Nicole storming into the living room from her soccer practice. "Brian! Brian! BRIAN! Where the fuck, are you anyway?" She screamed without giving Brian any other option but to go into the living room immediately.
Brian hurried inside the living room just wearing the small yellow color girly short. "I am here" he said while his eyes gazed over her body. She was all sweaty from the hard practice no doubt; her black t-shirt looked like a second skin over her pouty tits. Her tight sports pants revealing the deep curves of her crotch and ass, she smirked noticing her lust in her brother's eyes. She began to rub her crotch over the pant slowly in order to tease her poor brother; the bulge in between her legs was quite prominent.
"Oh Brian stop drooling like a pervert will you?" She mocked before adding, "Both you and I know that you won't be able to use my body like the way you wanted to, but I will use you in any way I see fit. So, why don't you be the good little bitch that you are and slip out of your pink short? I don't want it to get stained by your worthless dick." She smiled watching the 22 year old stepping out of his shorts to show off his shaved cock and balls to his little shemale sister, his face was burning with shame but his dick attained a full erection of merely 4 inch.
Nicole also slipped out of her pants, letting her thick long cock stretch out in freedom. She sat on a wooden stool and smacked her butt cheek playfully while glancing at Brian in a meaningful way. "Go on you little butt lapper, you know you love to lick the sweaty ass of your sister, your cock craves for the taste as does your tongue. Go ahead." Before walking to her behind, Brian couldn't help but admire the 6.5 inch soft member in between his sister's legs, no wonder why she is the boss of the house.
Brian dropped to his knees behind the stool; he saw his sister wiggling her firm shaped butt-cheeks right in front of his face, inviting him to do his job. He recalled the first day when Nicole forced him to sniff her butt as if Brian was a dog, he felt like vomiting but as time went by he secretly started to love the scent, and those humiliating French-kisses and the lap jobs but his hard dick always gave away his secrets to his sister.
Just as Brian began to press his nose in between her round butt cheeks, the strong aroma hit him hard, he gasped. Nicole sensing his brother's discomfort said in a sly tone, "Oops, I forgot to mention to you that today after the match I took a dump and well since the stall was scarce on toilet papers I decided to go green, since after all I have a wet organic toilet paper at home, YOU!" she giggled out loudly at the end of the sentence.
Brian repulsed at the very idea of licking shit off his sister's asshole. He had licked her ass before, sniffed it like a dog but never considered something that gross. But when he felt Nicole's strong hand pressing against the back of his head, he realized that it was not something of his choice. He must obey her because she demands so. "Come on you little dog, I am waiting. For the first time when I made you lick my asshole, did you think that you have come to a limit? Hell no, you are just at the beginning bitch. So hurry! Take good long sniffs as a starter."
Brian was helpless under the total control of Nicole as he began to sniff in the smell with each sniffs the strong scent began to took over his nerves breaking up the remaining of his will power as he was facing the reality from a new angle, he was nothing but a living toy for his sister who has the right to do whatever she feels like. "Damn it brother, is your lungs as weak as your pathetic dick? I want to hear you sniff, just be a good boy and take 10 long sniffs, NOW!"
Brian once again nauseate under the new degrading order. He clenched his eyes and began to long deep sniffs, one after other. Nicole found it more than arousing to have her brother obey her like a Mistress, no matter how much humiliating it was. Just as Nicole heard her brother's sniffing the smell of her shit she moaned and spread open her legs and began to slowly stroke her long cock. "That's it brother!" She giggled patted his head, stroking his black hair locks, "after the sniffs I want you to French kiss it before jumping to regular lapping."
As the day got worsen each second for Brian, Nicole's day was getting better she thought, "Today for the first time my brother, I will make you clean my ass inside-out with your worthless tongue, which is only good when serving me." She felt her cock throbbing each time she heard the sniffing noise coming from her behind. "Well, it's not that I am a bossy bitch, he also loves to serve me like the same way I love ordering him. It was me, who made him realize for the first time that he was a dog and a slave and now it's time to treat him properly like one."
Just as the sound of 10th sniff died down, Nicole turned her head back to see how his red-faced brother doing down there. When she saw her brother panting for clean air she giggled. Then her eyes roamed a little below to catch a glimpse of his small hard cock pointing towards the ceiling throbbing in between his legs. She wiggled her ass in front of Brian's face, "Go ahead, and kiss it my dear. Let me tell you something, you do everything I say and I might buy you a sex-doll so that you won't always have to go to toilet to jerk-off."
Brian's eyes lit with a ray of hope as he looked up to her face, "Really Nicole you would do that for me?"
Nicole smiled and nodded, "Yes you dirty little mutt, I will. You are my little sissy toy aren't you, so I also want to make my toy happy. Now off course your toy won't be a living thing like mine, but at least it's better than to go to restroom and flush down your precious cum, right?" She wiggled her butt again, "But that means you will be completely obedient no matter the command. Let me give you a prior warning, it won't be as easy as it seems. But who cares? If you put on a fight you will lose the doll, I will use you anyway. I have nothing to lose."
Partly from obedience and partly from the hope to get a doll, Brian touched his sister's rosebud with the tip of his tongue. Soon the bitter taste spread all over his taste buds but to his surprise he didn't feel like throwing up rather with each second he became more and more adjusted to it. After few minutes Nicole suddenly pushed Brian's head towards her asshole forcing him to encircle her asshole with his lips. "You kissed my butt-hole pretty well, my dear slut, it's time to even the score. I have a special kiss for you in mind."
