MISTRESS GAIA - MY BOUND & GAGGED ASHTRAY BITCH - HD

My slave knows that I always have a clean ashtray on my table. It's his job to make sure that it's there. I decide to relax and have a cigarette before I go out. However, there's no ashtray on the table and I can't find my cigarettes. I asked my slave and he said he doesn't know where they are. What a stupid answer, I gave him a slap and reminded him of his job to make sure everything is in it's place. After finding my cigarettes myself, I tell him he's going to be my human ashtray. To punish him, I get some rope and tightly bind him to the table. Then I put a "O" ring gag in his mouth to keep it open. What a novel idea, as he gargles and truggles to breathe as I pull his gag nice and tight. I get him to make use of his tongue by licking my shoes. Then it's time for my long awaited cigarette. As I light up and begin blowing my smoke into his face and mouth. My bitch will enjoy his punishement as he swallows all of my ash. When I'm finished my cigarette, I stub it out in his throat and leave him to choke. It's more fun having a human slut for a ashtray. I'll keep him there for the rest of the day, or perhaps until I have no more cigarettes...

MISTRESS GAIA - SILENCE IS ESSENTIAL - HD

My bitch of a slave was making too much noise, and he was also mumbling to himself under his breath. When I asked him what he was saying he got a bit lippy with me, and thought he could answer me back. It wasn't too long before I had him helpless and tightly bound. He's going to learn very quickly when I tell him not to make a noise, that's exactly what I mean. I begin his punishment with hand over mouth smother, what a great way to keep him quiet. As he struggles to breathe, I continue to apply more and more pressure until I see the panic in his eyes. After a while of his gasping to breathe, It's time to make him really suffer. I so love those muffled squeals he makes as I gag him with a rubber ballgag. However, another layer will make sure, as I tightly wrap pvc tape over his mouth. As he struggles and squirms, I leave him there to suffer in his breathtaking silence...

MISTRESS GAIA - BOUND & GAGGING ON HIS IRON BED - HD

My slave has been rather good, so I decided to reward him. I tell him he is going to have to lie on the bed while I consider what to do with him. He thinks it's a ordinary bed. Of course, I have my own version of comfort for my slaves. I get him to lie on my steel sprung bed, and tightly bind his arms and legs. The springs will dig into his body and make sure he is suffering. Because he complains it's not what he thought. I also put a nice tight ballgag on his mouth. All he can do now is struggle. However, there is no escape. I leave him there for a couple of hours until I return. I said I would reward him, so I have decided to allow him the pleasure of worshiping my feet. Although his ballgag keeps him quiet, I need him to use that tongue of his to make sure he licks my feet properly. So I change it for a headharness "O ring" gag. It's such a tight fit, and I so enjoy that gargling sound as I fasten it around his mouth. My bitch is now ready to have his reward, and I tell him if he makes a good job of licking my feet I may let him go. I taunt and tease him with my silk stockings. Then remove them to allow him to lick my feet. He struggles to get his tongue through the gag, and I tell him he must try harder. To give him some incentive, I tell him the next time he uses my bed, I may allow him the luxury to cum. However, not today!! I have a lunch engagement, and I'm going leave him tightly bound and gagged on his jagged iron mattress. He will remain there to suffer until I decide to return...

MISTRESS GAIA - JUST FOR KICKS - HD

Ok this video is self explanatory. I kick the out of my slave. He said he wanted to have a little workout. However, he doesnt do martial arts. So I decided to give him an introduction. I will use him as my kick bag. As I deliver some seriously crushing kicks to his stomach, he looks like he's in trouble. Of course that won't stop me. I'm having so much fun using him as target practice. I tell him if he manages to stay on his feet I won't whip him. Unfortunately for him, he goes down like a sack of potatoes. As he lies beneath my feet, I trample and stand on him. It's been a quick introduction for him. I'm sure he's going to feel a lot more of the power of Mistress Gaia...

MISTRESS GAIA - METALHEAD FOOTLICKER TOY - HD

I have my slave in a Zentai suit he is hooded and completely blindfolded. I have given him the task of worshiping my shoes and feet. If he does well he will not be punished, if not he'll be dealt with severely. Before removing his hood, I begin with a little test to see if my toy can manage to even find my feet. He's such a stupid slave. He fumbles and gropes with his head, and doesn't even know where he is. I remove his hood and show him where to position himself. He thinks it's going to be easy without his hood. However, I have other ideas. I get some metal tape and wrap it tightly around his face and head. He can't hear properly or see anything, It's also very hot inside his metal encasement. With only a tiny space for him to pop out his tongue, he's going to have to work hard to lick my shoes and feet. As he licks my shoes, I have to make sure he doesn't wander. Then It's time for him to worship my feet. I order him to use that tongue of his, and make sure he really licks my feet properly, especially all my toes. Due to his tight head bondage, he has difficulty breathing and is not performing well for me. I am going to have to resort to a severe punishment for him. His muffled gasps are amusing, as he desperalety tries to breathe. I tightly zip him up in his metal encasement, leaving him to suffer until I decide to return...

MISTRESS GAIA - BOUND & LEFT SQUIRMING OVERNIGHT - HD

My slave has not been doing what I tell him. As a punishment I ordered him to kneel in a corner of my dungeon until I decided what to do with him. I was making some calls and looked up to find him wandering around. He said he wanted to stretch his legs. I was furious with hiSs disobedience, and I'm going to make he doesn't wander around anymore. I get some rope and tightly bind his arms and legs so he can't move. Then I place him in a latex bodybag and zip it up, with a hood over his head to finish him off. He's completely helpless and begins to struggle, I tell him he's not going anywhere. As a punishment he will spend the whole night in tight latex bondage. I put out the light, and leave him in the dungeon. When I return in the morning he still shows signs of pathetic stuggles to get free. Of course he can't escape. As he squirms inside the latex body bag, begging me to let him go. However, I'm going to continue with his punishment. I tell him to be quiet, and assist him with some hand over mouth smother. His struggles become more frantic as he gasps for air. It's so amusing to see those hands of his pressing against the latex and getting nowhere. I decide to really make him suffer, as I facesit on him and give him the pleasure of my silky pantyhose with a tight ass smothering on his face. He struggles desperately and is extremely hot inside the latex body bag. I ask him if he has learned his lesson and won't disobey me again. I don't bother listening to his response. I'm just going to make sure by leaving him in his bondage for another night. Perhaps then he'll understand what it means to serve Mistress Gaia...

MISTRESS GAIA - SUFFERING IN SILENCE - HD

I have had my slave in his cage all day. He's been waiting for me to arrive and let him out. Of course, it's only the beginning of his ordeal as I am going to have some fun with him. I open his cage and tell him to crawl to the front. I have some bondage rope and cuffs that I'm going to use to tie him tightly to the cage. With him nice and secure, I warn him he's going to suffer for me. I can see from the expression in his eyes he is afraid, and so he should be. I am going to smother him until he begs me to stop. I think some hand over mouth will be just the thing. As I place my hands over his mouth he begins to struggle, of course he can't escape. I tighten my grip, and watch as he truggles for air. With his large gasps for air just long enough, before I once again place my hands tightly over his mouth. Eventually It's time for a breather. However, for him but it won't last. I bring out a pair of my favourite latex gloves. When I show them to him, I can see the panic in his eyes. I so enjoy that distinctive sound as I pull the tight latex over my hands. I quickly place my hands over his mouth, and watch as his eyes begin to bulge as he gasps for air. It's going to be a breathtaking time for my bitch as he suffers in silence, and his suffering will continue until I until I think he's had enough...

MISTRESS GAIA - BREATHTAKING DARKNESS - HD

Today I'm wearing my Zentai suit and I have my slave on the floor ready to recieve his punishment. As he's been getting on my nerves with his inscesant back chat, I'm going to shut him up. I have tightly wrapped his head in vetwrap, causing some scensory depravation. Just the thing to keep him completely under my control. His muffled squeaks are soon stifled, as I give him some hand over mouth smother. I continue with facesitting, along with some nice scissoring. I so enjoy hearing those breathtaking gasps as he struggles and squirms to get free. Of course there's no escape, and he's going nowhere.

MISTRESS GAIA - DARK DESIRES - HD (Extended Version)

I had my slave in mummification earlier. I needed to check him over, so I moved him to the medical room to give him a examination. While I was preparing, the bitch had the cheek to almost fall asleep. So I'm going to give him something to doze about. We'll soon see if he's ready to stay awake. Or perhaps I can assist him with his afternoon nap. Wearing my tight latex gloves, I quickly cover his mouth. He desperatly struggles and gasps for air, however he's going nowhere as I contunue with his punishment. As I cover his mouth his helpless muffled squeaks become quieter. I continue to mercilessly press down with my latex covered hands, and I can see the fear in his eyes as he begins to panic. The effect completely airtight, as his breathless suffering continues. What a interesting scenario, as my bitch is suddenly wide awake and having difficulty breathing. Of course he's in safe hands...(pun intended) and I'm going to enjoy every minute making him helplessly struggle and suffer for me. As he chokes and gasps for air, I remove my gloves and stuff them deep into his mouth. The gagging effect almost completely soundproof, as my latex gloves fill his mouth. I'm not done with my bitch just yet. As he struggles to breathe, I finish him off with layers of clingfilm tight around his head and face. What a enjoyable sight to see, with those eyes bulging as he desperately tries to breathe. His latex gag is so unforgiving, as he helplessly struggles and suffocates in his airtight clingfilm cocoon. Mffff...

MISTRESS GAIA - TIGHT LEATHER GLOVES SMOTHER

I have taken my slave from inside his cage, and put him on top. He is tightly bound and can't escape. I'm going to treat him to some hand over mouth smothering. To ensure he enjoys what I have in store for him, I have chosen a beautiful pair of sensual leather gloves. I pull them over my hands and make sure they are really tight, the soft leather is so comfortable as I stretch and wiggle my fingers. As my slave struggles on top of his cage, I can see he is aware of my intentions. I begin by placing my hand over his mouth and pressing down, making sure the leather is completely covering his mouth. I so enjoy seeing that fearful look in his eyes as he gasps for air. I continue to make him suffer, as I alternate my hands over his nose and mouth so he can't breathe. As I tighten my grip, he beging to panic and his gasps get more frequent. However, I'm not nearly finished with my bitch. He's going to suffer a lot more. There's nothing like latex to make me feel great. I so enjoy wearing it and working with it. I have some beautiful pieces in different colours, it's so breathtaking... don't you think? My slave knows he isn't going anywhere, as I throw my latex over his head and pull it tight against his face. He sucks his last dregs of air as the latex sticks to his face like a second skin. I'm enjoying his suffering so much that I pull tighter and tighter. It's time to change colours, as I release the latex I give my bitch a choice and order him to pick one. He picks a shade of pink, almost lilac. It's so beautiful... However, like myself it is very unforgiving as I quickly encase my slave's head and face. He gasps and sucks, as once again I take every last breath from him. After several attempts to beg for mercy, I decide to give him a break. However, not in the way he thinks. I have a new solution to keep him in his suffocating hell. I have a plastic bag that I quickly pull over his head. He gasps and tries to fill his lungs with air. It doesn't last as I pull the bag tight around his neck and face. I love to watch those eyes bulge as he helplesly struggles and squirms for air. I'm not sure how long my slut will last, it depends on how much time I'm prepared to spend on him. He's such a lucky slave to have such breathtaking moments with Mistress Gaia...

MISTRESS GAIA - MY BOOTLICKER WORM - HD

I ordered my slave to clean all my boots. I arrived at the dungeon and found him messing around with clingfilm. On examining my boots I could see he hadn't even bothered to clean them. I asked him why and he lied to me and said he had finished. Since he had clingfilm in his hand, I thought I would teach him a lesson. He's going to be my little worm for a few hours, and use his tongue to clean my boots. I completely bind his whole body tightly with several layers of clingfilm, then finish him off with more tight layers of pvc tape. My bitch is now completely helpless. As he helplessly struggles to move, I order him to lick my boots. He must follow me and make sure he keeps up. I have my flogger at hand to give him some incentive. He will be whipped harder and harder if he doesn't obey my instructions. As he wriggles and rolls, I have to beat him more and more. I then put him in a tight collar and leash, and give him a good tugging to keep him in line. I know he's getting extremely hot, and I enjoy seeing him suffer. My bitch must learn his lesson, and for the rest of the day, I'm going to leave my little worm on the floor to struggle and squirm until I return...

I have my slave tightly bound on a iron spring bed. Of course there's no matress, and as he struggles I know the springs are making him very uncomfortable as they dig into his back and legs. Until I decide what I'm going to do to him, I'll relax with a cigarette. My bitch will be my human ashtray, and I'll order him to accept all my ash in his mouth. I keep his mouth open and place a plastic gag in it to keep it open. I enjoy seeing him choke as he tries to breathe. I light up my cigarette and look down on my slave as he struggles to breath. I make it harder for him as I use his mouth for my ashtray. As he struggles to breathe, I blow my smoke down into his throat, and allow him the pleasure of my spit as he coughs and chokes as he struggles to breath. As I come to the end of my cigarette, time to put it out in his gaping mouth. I so enjoy that gargling sound as he chokes and suffers on the burning stub...

MISTRESS GAIA - CAGED & SMOTHERED SHOE LICKER ASHTRAY - HD

ENGLISH SPEAKING - I have my slave in his cage in a Zentai suit. He is tightly gagged and bound. As a punishment I have left him there for many hours. I return to find him struggling and squirming, with muted sounds as he tries to cope with his punishment. I unzip his hood and remove his gag. He thinks he's going to be allowed to leave his cage. Not so... I'm going to enjoy a cigarette, and get him to clean my shoes before I even consider his release. I warn him to get his tongue licking, and he must make a good job cleaning my shoes. Otherwise, I'll punish him more severely. As I begin to enjoy my cigarette, I order him to open his mouth and receive my ash. Then he has to continue to lick my shoes. It's not long before he begins to cough and mumble. I get fed up listening to his noise and put a tight stocking gag on his mouth to shut him up. Stockings are so useful, they are really tight and my slut can't speak as he gargles and tries to swallow my ash. However, he's still making too much noise so I'm going to make him really suffer. I get out one of my favourite pieces of latex, It's extremely effective to make sure a slave is kept silent. I throw it over his head and face, he panics as he knows what's coming. As I pull the latex tight over his face, it sticks like a second skin. I so enjoy seeing every little contour as my slave squeaks and helplessly gasps for air. With his stocking gag already getting tighter around his mouth. Also, as it tightens around his head and face the latex is so unforgiving. I continue with his breathtaking suffering until he begs for mercy. However, I'm not quite done with him yet. I have to go out, so I'll leave my slave tightly bound in his gage. As I put out the lights and walk to the door, I so enjoy the sound of my slave gasping for breath under his latex sheet...

Today I have my slave on his knees waiting for me. He has been in a stressful position with his arms bound for a long time. It's part of a punishment I am giving him. He is also going to worship my feet and learn to obey me in future. I begin by getting him to lick the soles of my sandles, he seems to be having some difficulty and mumbled something as I press them hard against his face. It's time to shut him up, so I decide on some foot gagging. He must keep his mouth open wide, and enjoy the power of my foot as I shove it to the back of his throat. However, the stupid slave keeps moving his head so I have to put a stop to that. I get my leather belt and whip his nipples before pulling it tight around his neck to keep his head in place. If he moves too much he will choke himself. I continue to push my foot to the back of his throat while pulling tightly on the belt. What a great pleasure to see him suffer, and so amusing as his gargled squeaks are stifled by my beautiful feet at the back of his throat...

He's going to experience some serious tightness. I totally bind him in clingfilm, then tightly bind his head with tape laeving only a small space for him to breathe. It's so amusing to hear his muffled attemps to speak as the tape tightens around his head and mouth. With him tightly bound in his clingfilm cocoon, I place him on the bed and tell him I'm going to have some fun. As he helplessly struggles, I hope he's enjoying his new TIGHT situation. He can't move much, and getting extremely hotter by the minute under his extreme bondage. As he becomes more uncomfortable, I punish him even harder with foot smother and head scissoring. As he helplesly struggles to be free, I enjoy watching him squirm. Totally encased in his very own shades of Blue...
