Accessorize and utilize a femboy

"mmm-" Karis purred, her tits pressed into the comparatively small and slim stature of her brother. "I'm never gonna get tired of that-" she said as she stroked the last few pulses of hot goo from her twitching length. It burbled out in spurts all along Luke's already cum-stained leg.

Her shoulders slouched in blissful relief as she took a step back to take in her handiwork. It brought a spark of joy to her mind to see him, now some assed-up twink with his leg covered in her jizz.

Idly she was aware that more than the things she had input had changed, this hallway hardly looked like her home, similar in some ways but if she were more caring a person she might've been worried.

Almost lazily she flipped the app open again, the familiar text box appearing again. She hummed to herself, swaying her voluptuous virile figure back and forth, causing all sorts of jiggly flesh to bounce and stick together (jizz). "Maybe we'll start slow, yeah?" she nodded. "A little of this..."

-jeans -black hoodie +small gym shorts +crop top

his clothing morphed like the goo sticking to his leg, shifting and twisting until his effeminate little form could be seen through the gap between shorts and shirt, his little dick and round ass barely contained in the tight shorts he now wore. "...and a little of a mood shift..."

+slut +confident bratty bitch

The change was less visible here, more in the subtleties of his stance and, oddly, how much cum he had on his legs... and the size of his bulge.

She dragged her fingers along the pulsing length of the underside of her shaft, small spurts of spent jizz dripping from the tip. "Thaaat's more like it... look at you Luke, your just a hot piece of ass now..."

-frozen in place +does whatever his sister tells him to

immediately the masculinity challenged man continued his earlier tirade... just in a higher vocal tone...

"Fuckin' sake sis, it's always a thing with you and your slutty fat dick, always jerking off WHEREVER and WHENEVER your throbbing-hot-cum-stuffed-balls get the slightest bit excited! We'd do better just renting you out to every horny boy slut in the fucking county than having to deal with your fat juicy ass ourselves!"

Despite still spatting spittle everywhere, his eyes just as rage-fueled before, he noticeably was redder elsewhere on his face than before and his angry eyes kept getting drawn into the lascivious curves of his younger sister's much more voluptuous figure.

"Yeah-yeah, love you too big bro, now get down on your knees and lets see how useful that cute little mouth of yours really is."

His eyes filled with rage even greater somehow, even as his cheeks deepened shades previously unknown. "Are you fucking serious right now? Suck your cock right now even as you have that fucking fat mess behind you. Hot fucking chance sis." he raged even as he began to kneel.

"Ughhhh. I guess if I have to to keep you from making any more of a disgrace of yourself... well... fuck. Fine!" almost as explanation to himself as he leaned in, easily and readily starting to lick the thickly growing shaft dwarfing his small hands. His expertise was immediately on display, the raw desire in his eyes betraying his words as he went to work, almost seeming oblivious to the ridiculousness of the situation as he lapped up the dried cum sticking and hanging from Karis' previously spent loads. "Fuck this thing stinks, I can't believe you would just walk around-mmh-with this stupid thing steaming dick *slurp* hanging, just letting-mmph-your stupid hot stench get everywhere."

Karis grabbed her brother's tousled short hair, gasping, staring down between her massive tits at the shifting small head licking and sucking her pulsing thick shaft clean.

Luke glanced up with, arousal and anger both written in his gaze. "The things I do as an older brother, seriously you guys should be worshiping me for the things I do." He placed his lips, so small and effeminate in comparison, on the tip of her virile twitching cock, warm air rushing out against her cum-dripping hole as the spear shape of her tip spread his plush lips ever so slightly from the pressure applied there.

Karis grinned wanly down at her brother. "uh-huh? Is that it bro? You just doin' me a favor? You're not the least bit excited to be taking my fat cock down that slutty little throat? Or is that not your pathetic little dick I see poking into your slutty boy shorts?"

Luke's blush deepened, however still remaining defiant in posture as he **** fully half of her massive dick straight down his throat.

"OHH-hh-holy-f-fuck!" Karis moaned, head thrown back, nearly falling off-balance but for the throat holding her up. She reached out reflexively, sparks shooting through her nervous system as she grappled onto her brother's messed up hair once again.

"yes-ohfuckyes-take my cock bitch!" she growled, tugging him deeper and deeper as he gagged and moaned, more and more of the anger disappearing as it was replaced with lust. She used him, thrilling in the power of her virile, voluptuous skin. The hole was tight, ohh so fucking tight, it took all of her strength to make it the last few inches and impressively he somehow handled all of it, gagging, moaning and bitching all along the way.

It took all of three small thrusts once he was all the way down to send her over the edge, new to all of it as she was. She yowled with bliss as her balls pulled taught, heavy and hot between her thick thighs and audibly she heard the gooey squirts somewhere far below as her cock deposited girl spunk straight into his stomach. Still as she came down from the high she didn't want it to stop, after all, why should she?

Quickly, while still impaling the slut of her big bro, she took a pic of herself and added...

+huge loads +multi-orgasmic cock

virility surged in her core, the physical feeling of her balls actually refilling almost sending her over the edge immediately. She grunted as her muscular fingers twisted into the knots of his hair and she thrust in and out, in and out.

Luke's face grew redder and redder, eyes lazing further and further back into his head as Karis blew one load, two, five... only ever giving him enough of a break to get air every couple of orgasms, filling him up like her own personal cum-dump...
