Nice

You figure Brad runs into a lot more naughty sluts than innocent little schoolgirls and he will find you more tempting if he thinks there's something left to corrupt.

You find your sister's make up and practice until you have pouty soft pink lips, delicate lashes, a modest blush. You stare at yourself and wish you had a real cock to fuck the coquettish waif in the mirror. Smiling you realize you can just use Brad's instead as you slip into silk panties that barely contain your thick ass and squish your hard little clit. You shiver as you slip on your white satin thigh high stockings, imagining rough hands running across them. You twirl in your plaid pleated skirt and giggle as you try to sneak a peek at your own ass. By the time you complete the look with a white peasant blouse, blue blazer, and Mary Jane shoes, you are the spitting image of a virginal sissy schoolgirl. "Well, not for long." you coo at your reflection.

You find Brad downstairs on the couch. Still naked, languidly stroking his hard shaft. He's watching porn again, but he seems bored by the plastic looking bimbo filled by cocks at every entrance. You decide to give him something that will really excite him.

"Eww gross! What are you watchin', big bro" you say in a shockingly convincing impression of a naive teeny girl. You slip beside him on the couch, your skin blushing everywhere his surprised, lustful stare rests. You love this brief moment where you seem to have him at a disadvantage. It doesn't last long.

"Aww don't be like that, lil sis. Family movie night used to be your favorite. Here, sit on my lap just like old times." Brad lifts you effortlessly onto his lap, his hard cock resting between your soft, silk panties and softer buttcheeks. You can't help but whimper needily. You try to remember that you are supposed to be the one seducing him, but it takes everything you have not to break character and beg him to breed your sissy pussy.

"B-b-but Brad. Daddy wouldn't like us watching this kind of movie. And especially not with your-whimper-thingy rubbing on me." Brad seems to like your little role play, his cock throbs against your panties and his hands begin to roam over your soft legs. You bite your lip, begging yourself not to beg him to fuck you. Brad was never the patient type. You just have to tease him a little longer.

"Nngh. Don't worry. Be our nngh little secret. I'm unh hurting, can't you feel fuh how swollen I am?" You can feel it alright, Brad has moved your pretty pink panties aside to push his fat cockhead up against your puckering pussyhole. His other hand slips inside your blouse and toys your hard nipples. You yelp incoherently, discovering your nipples are as needy and sensitive as your sissy holes just as you feel your brother about to enter you, to make you his. If only you can give him that final push.

"Buh buh BRAD! Wait! I can't! I'm a good girl! I'm a virgin. I never even kiss-" Brad forces the word back down your throat with his powerful tongue. You drool around it, sucking on it, caressing it with your own dainty, darting tongue. You moan in his mouth as he enters you suprisingly gently. His cock is inside you, sinking deeper as you do, lost in a swirl of sticky sweet kisses, throbbing hard nipples radiating with painful pleasure, and an even harder, throbbier cock spreading you so wide and willing.

"See, a kiss isn't so bad, is it? Turn around, I want to see your face as I break you." He pulls away from your kiss and a strand of spit trails behind. You catch it on your tongue, straddling your big brother so he can see your flush, feminine features distort into excruciating ectasy. You feel his powerful hands guide you back onto his hard cock, and you coo contendly as you slide back down. You feel every contour, ever vein kiss the insides of your virginal sissy cunt, every micron of it lighting you up inside, causing you to fill your panties with sissy spurts even before you reach the base. You shudder and spasm and fall deeper, somewhere deep inside you find a last vestige of will power to give Brad one last taunt.

"Please, big bro...be gentle. It's my fuh fuh first time." You see a fire burn behind your bully brother's eyes. Contemptous, arrogant, and hungry. He swallows your mouth with his own and begins fucking you hard, drinking down the whimpers and moans he pounds out of your sissy cunt. Your sissy clit dribbles dumbly, the lie of your innocence stained by sticky squirts filling your panties and running down your legs. You are mumbling incoherent prayers to your new god and he is shoving them back down your throat with his insistent tongue. He only needs one hand to hold you in place while his hips jackhammer his cock in and out of you in a continous blur. The other hand squeezes aching orgasms from your swollen nipples. You drool and dribble and flop helplessly on his cock. You can't tell when one sissygasm stops and another ends. Your mind breaks and you blissfully bounce on your brother's cock, content in the knowledge that you are definitely his bitch now.

"That's it...take it...take my seed...BITCH!" Brad floods your guts with his alpha seed. You gurgle and giggle as you feel it fill you up and dribble outside of your well breeded ass. It's official now. He's branded you. You will always be his bitch. You smirk mischieviously at the thought.

Brad dumps you on the floor like a discarded cum rag, which you guess you are. "Damn! That was better than I expected." You blush with pride even as he wipes his sticky cock on your cheek. "So the question is...how do we top that?"

You smile seductively...you might have a few ideas.
