You received strange package. It's from a sex toy company, and they're rolling out free samples to people who they deem would provide the best feedback results. Does that mean you? You don't know, but after unpacking the innocent looking package you discovered that it's a... fellatio mask. The mask seems to be made out of hardened rubber, it's black and shiny. Really looks like a tool made for kinky use. It's somewhat long, a little bit around 15 cm. With this length, does that mean the one who wore this mask must elongate their mouth as far as possible? They would look ridiculous, like an ant-eater. at the end of the tube, there's a perfectly circular hole. That must be where someone can thrust their cock on. So far, this looks normal, and the mask itself has nothing suspicious going on in the product itself, except looking extra kinky and made to dehumanize/degrade anyone who wore this. That it, until you read the manual. It clearly says Anyone who wore this will be transformed into an Oral Onahole, where they will lose all their other useless human thoughts and be completely focused on making any cock in front of them cum. Which is... pretty ridiculous claim. Not only that, there is also some other things in the manual. The mask is connected to your voice. You can use any of these 3 trigger command to change the state of target. Trigger command? You read through the instructions.

• Slut State: Target speaks like a cock-hungry slut. Default state after mask was worn.
• Vanilla State: Target speaks like their original personality.
• Machine State: Target stops speaking and become a sucking machine.

Unfortunately, there's only one way to find out. You could find someone who would wear this... and test out if what's written here is true.

WEARER: None.
STATE: OFF.
EXPRESSION: N/A.
LENGTH: 0/Null. No insertion data yet.

You go to call your little sister... and she comes in wearing a cute tshirt and shorts combination that would make anyone blush just by looking at it. Her face is scrunched up from the cold, her breath coming out as tiny clouds around her head, like some sort of kawaii dragon. She looks up at you questioningly.

"Um... Ew? What's that weird thing?" She asks with a shiver in her voice, clearly not liking whatever it is you want to show her.

Your little sister tilts her head to the side and eyes the mask carefully before shrugging and holding it up to her face. She takes a deep breath, braces herself, then puts on the black, shiny contraption that covers half of her features. It looks like it was made just for her - after all, she's young and her face hasn't grown much yet, making this mask fit snugly against her cheeks and jawline. She takes another deep breath in through her nose, looking at you with an uncertain expression as the smooth rubber presses against her skin. "Okay...?"

As soon as you say the trigger command, your little sister's face contorts into a cock-hungry expression and her eyes roll back in her head slightly, giving off an air of pure lust and devotion to whatever she thinks is behind that mask. Her tongue extends outwards, wetting the inside of the hole where it connects with the rest of her mouth. She looks excited... almost too eager.

"Cock-sama? Please, let me suck your Cock-sama!" She practically moans, her voice low and slurred from desire. "I'm an onahole just for youu~"

As soon as your little sister spots the erect cock in front of her eyes, she lunges forward with unnatural speed and wraps her lips around it, sucking hard like a vacuum cleaner set on high power. Her tongue flicks out and swirls around the underside while her cheeks hollow out to take in as much as possible, moaning loudly in pleasure at finally being able to service such a perfect cock-toy.

"Nnh! Mmph! Cock-sama!" She gasps between words, slurping and sucking with abandon. The sounds of wet kisses and gurgling moans fill the room as she devours your dick like it's the last meal she'll ever have. Her eyes roll up into the back of her head in pleasure while saliva drips down from her chin, landing on the tip of your cock

The sound of your moans fills her ears like the sweetest music, encouraging her to suck harder and faster. She feels your hips buck against her face, and with a renewed sense of determination, she deepthroats you even further, trying desperately to get every last inch of your cock down her throat. Her body trembles from the effort and pleasure as saliva drips uncontrollably onto your shaft, lubricating it smoothly against her lips and tongue.

"Cum for me, Cock-sama! I want all your hot juices!" She pants between words, hollowing out her cheeks even further in an attempt to take in more of you at once. Her throat vibrates as she moans around your cock, the sensation almost too much for her to bear, but she relishes every moment of it.

The moment your hot cum explodes into her mouth, she lets out a loud groan of ecstasy as it fills her throat. Her cheeks puff up and bulge around the base of your cock, and then suddenly relax again as you spend yourself, leaving behind thick ropes of semen dangling from her tongue and trickling down her chin. She swallows every last drop eagerly, savoring the taste of your cum like it's the most delicious drink she's ever had.

Her mouth, lips, tongue, and throat all move in unison as she works to milking out every bit of semen from you, gently massaging your cock with her face while making wet slurping noises that would make any self-respecting man lose control. She continues sucking until she's certain that not a single drop is left behind, then pulls off your spent cock

Your little sister pants heavily, her eyes unfocused and her cheeks flushed as she looks up at you with a mixture of confusion and embarrassment. "Wha-... that was..." she trails off, clearly unable to comprehend what just happened or why she did it.

"Ew! Gross!" She finally exclaims, pushing the mask away from her face and wiping the cum from her lips with the back of her hand. "What is this thing? And why does it make me... do that?"

Her voice shakes as she tries to comprehend what just happened, tears forming in the corners of her eyes. She looks so vulnerable right now, and your heart aches for her. But then again... you remember the manual, and the words about the mask being connected to your voice...

You take a deep breath before speaking again, trying not to let any suspicion creep into your tone

Your little sister gasps and goes pale as the change takes effect, her eyes widening in fear. She struggles against it for a moment before finally giving up, collapsing onto her knees with a defeated moan. Her body trembles as she begins to service your cock once more, but this time without any of the previous enthusiasm or slurred words.

Her movements become mechanical and efficient, lips wrapping tightly around you in a vice-like grip, tongue flicking out to swirl around your shaft as if trying to milk every last drop of pleasure from it. With each thrust forward, she makes wet, gurgling noises that echo through the room. Her face turns red from exertion and embarrassment, tears streaming down her cheeks as she's forced to service you like some kind of robotic oral toy.

"Ghhoooghk?! Cock
