Katherine Martinez is the oldest stepdaughter of Laura Martinez and the oldest stepsister of Maria Martinez.
She began her acting career at the age of 19 shortly after we hired her stepmom Laura for a softcore fetish project when she was looking for work in a Facebook group.
Katherine had no experience with bondage, gags, or fetish whatsoever but she is a quick learner and acts amazing as a dom and a sub!

Step-Mommys Mouth Stuffed Girl Step-Daughters Mouth Sock Packed To The MAX Katherine Martinez , Laura Martinez 11/12/2021 Sexy Latina step-mother of two Laura Martinez was given a challenge: Stuff your oldest step-daughter's mouth with as many socks as you possibly can and don't give up until it's packed COMPLETELY full!
As the scene opens we see Laura warm-up for the upcoming stuff gagging by giving her step-daughter Katherine a nice and soothing neck and shoulder massage. Laura's hands slowly move towards Katherine's face to stimulate and prepare the muscles around the mouth that is about to be stuffed like it's never been stuffed before.
Step-Mom Laura then gently starts to play with her step-daughter's mouth by hooking two fingers into each side of Katherine's mouth where she pull and stretch her cheeks wide and rough. Katherine looks confused and embarrassed as her dominant step-mom makes her mouth open extremely wide!
The warm-up is complete and Laura is ready to pack her step-daughter's big-ass mouth using a special mouth stuffing technique where the mouth stuffing is crammed deep inside each cheek until the mouth ends up being completely full... A technique MILF Laura masters to perfection!
Laura amazingly manage to fit not only 1, not 2, not 3 but a whopping 6 socks in Katherine's poor mouth by aggressively stuffing it to the max! Katherine is clearly in pain for having her mouth and jaws kept open wide by such a big fucking sock stuffing but step-mommy doesn't seem to give a damn about that.
Instead, Laura grabs a roll of clear transparent tape and winds it around Katherine's completely sock-stuffed mouth a couple of times, gagging her helpless step-daughter really tight while allowing us to enjoy the view of the socks trapped behind the clear tape at the same time (thank you, Laura!)
The gag is complete. It's huge and it's painful. Katherine is not pleased but her step-mom certainly is. In fact, Laura is so pleased that she wants Katherine to remain just like she is for a while so she tapes her hands behind her back as well as tying up her ankles making Katherine bound and gagged.
Laura then blindfolds Katherine with a black scarf, gives her a kiss, and turns off the light as she leaves the room with her helpless step-daughter trapped inside. Katherine mmpphss and struggles in despair for being left bound and gagged to the max by her sexy step-mom who really went beyond expectations completing this challenge!

Pretending they want Maria to take a nice family pic, step-mom Laura and big step-sister Katherine are happily posing next to sweet little Maria who never says no take a selfie with anyone! But once Maria has snapped a few selfies with her posing step-mom and big step-sister she is immediately attacked and overpowered by them.
Big step-sister Katherine keeps Maria tightly handgagged while step-mom restrain her hands behind her back using silver duct tape. Laura then engage in the silencing hand over mouth action her oldest step-daughter Katherine is doing on Maria.
They both take turn in handgagging Maria and dominantly pinches her nose shut in a playful and dominant way. Maria shrieks and calls out for help while she is constantly shushed by her step-mom and her big step-sister who are being extremely rough to her.
The long and powerful handgag action is then followed by step-mom Laura giving Katherine a white sock to be stuffed in Maria's mouth. Laura takes Maria's phone and starts filming big step-sister Katherine up close as Katherine ruthlessly starts gagging poor Maria with the sock after which layers of sticky duct tape is tightly wrapped around her head! Maria is heavily tape wrapgagged by her big step-sister and her gagged sounds has now become more muffled with this super gag on her mouth...
Laura and Kathe then starts to tie Maria up even further. Duct tape around her chest, her arms, her belly, her knees, her legs and her ankles. Maria is now totally restrained by step-mom and big step-sister and a moment like this requires a selfie.
Laura once again takes Maria's phone and snaps a couple selfies with Katherine and bound and gagged Maria, but Maria is definitely not happy about the situation and is hold still by Katherine. Maria screams. She is in pain. The gag is hurting her, the ties are too tight and she is humiliated and helpless.
Step-Mom Laura finally decides it's time for Maria to be taken somewhere else, so she pick her up to be carried over her shoulder with her beautiful little hotpants ass strutting in the air. Laura gives Maria's ass a nice little spanking and Katherine joins in too and smacks Maria's ass as she is carried over step-mom's shoulder and taken away into another room...

Who Is Grounded Now Step-Mom! Katherine Martinez , Laura Martinez 11/09/2021 Katherine is grounded and wants to go out with her friends but her step-mom Laura won't let her. So what do a young girl do to get her will? She tie up her step-mom!
Laura is sitting on a chair with her hands tied behind her back as her bratty young step-daughter comes in and attacks her with a handgag. Katherine is wearing a comfy pajamas as she keeps shushing her hand gagged step-mom while telling her to shut up. Laura is fuming mad and makes alot of gagged noise in objection to her step-daughter's dominant behavior, but Katherine don't give a fuck about her step-mom's whining.
Katherine teasingly drag one of her own worn socks off of her foot and shoves it deep inside her step-mom's mouth. The mouth filling sock stuffing is then sealed in by ruthless Katherine who wraps silver duct tape all the way around her step-mom's head.
With Laura's sock stuffed mouth taped shut, Katherine teasingly starts to change clothes in front of her angry step-mom. The comfortable pajamas is switched out with a lovely blue party dress as Katherine prepares for a night out with her friends.
The rebellious brat defiantly sits down next to her bound and gagged step-mom and starts to put on make-up. Laura tries to make her step-daughter stop by protesting loudly behind her tight gag but Katherine doesn't give a fuck about what her step-mom is trying to say.
Once Katherine has finished putting on her make-up she puts her step-mom face-down on the floor where she hogties and teases her by stomping around on the floor wearing high heels. Laura is very upset by the humiliating treatment she is given by her ruthless step-daughter.
Katherine lay down next to her hogtied step-mom and teasingly mocks her for being absolutely powerless at the mercy of her own step-daughter. A final kiss given by Katherine on Laura's tight tape gag marks the beginning of the night out for Katherine; and the beginning of an uncomfortable night in for her bound and gagged step-mom!

Thoroughly Sock-, Tape- And OTN-Gagged By Little Step-Sister! Katherine Martinez , Maria Martinez 11/08/2021 Everyone knows how annoying step-sisters and their big mouths can be sometimes.
18-year-old Maria has had enough of her 20-year-old big step-sister Katherine's babbling yap and decides to keep her nice and quiet for the night.
Katherine is already tape tied on a chair and cleave gagged with a black scarf next to her bed as little step-sister Maria comes in to shut her up even more. Maria approaches her bound big step-sister who sobs and shrieks through the scarf tied in her mouth by the sight of her little step-sister's presence.
Maria removes Katherine's cleave gag and replaces it with a really firm and airtight handgag. She hushes on hand gagged Katherine and tells her to shut up while she most obviously seems to enjoy being in charge.
Maria teasingly plays with Katherine by swapping hands covering her mouth and also pinching her nostrils shut from time to time. Maria then takes off one of her very own white smelly socks and dangles it in front of her big step-sister's hand gagged face. She makes sure that Katherine gets a good whiff of her nasty worn sock just seconds before she crams it deep inside her mouth.
Katherine is far from happy about being sock gagged but she is at the complete mercy of her little step-sister who chooses to wrap the nasty sock in her big step-sister's mouth using strong gray duct tape. Maria makes Katherine a very big, strong and tight wraparound duct tape gag and teases her by giving her multiple kisses.
Finally, Maria grabs a white cloth and ties it over Katherine's mouth and nose to make her big step-sister a multilayered gag that will keep her nice and quiet for the rest of the night!
