Meet Onyx, the Colorado pup who calls himself a cumdump, pisslover, and faggot. He’s here to prove he’s as usable and dirty as he advertises, with a primal lust for feet, armpits, and the golden shower. From his first pants-pissing revelation to becoming a human urinal, prepare for a raw, unfiltered journey into his filthiest desires.
MasterMarc: Hi Onyx, your social media description made me incredibly curious. Are you truly as usable and deliciously dirty as you promote yourself, boy?
Onyx: I do consider myself a dirty boy/pup and open to be usable like a cumdump of course for the right people I need to be comfortable with them. But feet, armpits, and piss totally turn me on. So I guess you can say I am as dirty and usable like I say to the right guy.
MasterMarc: Okay, who is this “right guy” for such wild action, and what glorious limits do you hold when you’re with Mr. Right?
Onyx: Someone I trust. I like to talk for a bit before committing to a hot dirty time or a regular dirty time. And it doesn’t always have to be dirty. My limits are definitely no permanent marks, hard drugs, and of course when I say no more I mean no more. Got to keep myself safe first and foremost (minus the condom of course, I cum too much to use those).
MasterMarc: Hehe, that’s a damn good reason to be on PrEP. Let’s get down to the truly dirty stuff you crave. What’s the raw, intoxicating attraction of filthy action for you, boy?
Onyx: Honestly, I don’t know what it is, but the smells of sweaty pits and feet get me going, and piss… I just love the way it feels when I piss my undies or get pissed on; something about it is so pleasing. Even the taste makes me happy.
MasterMarc: Thinking back, I had my first piss games when I was eight. It was the thrill of piss and cling film that fascinated young MasterMarc. What were your very first steps into this deliciously dirty world?
Onyx: It started back when I was 18. I saw some videos online and pics and was intrigued. That night after jacking off, I decided to piss my pants and then got horny again. Then next day I was chatting with a guy who said he was into piss and feet. Hooked up with him and got really into it.


MasterMarc: Unfurl the details, boy. Tell us a little more about that first, deliciously dirty meeting.
Onyx: At first I was nervous and definitely we both got pee shy. But after awhile and some foreplay licking each other’s feet smelling and licking each other’s pits and yes, dirty underwear. We both starting lying on each other. It was so warm and felt amazing. Then I started to suck his cock while he was still peeing. It was like nothing I ever done, I loved it, it was amazing, the taste was so good. He kept pissing in my mouth like the floodgates opened. I swallowed some and thought how amazing this was. After he was done, we fucked, and then my mouth once again became his urinal, this time drinking it all.
A Human Urinal: The Ultimate Surrender
MasterMarc: What makes drinking the piss of others so uniquely special, so utterly compelling for you?
Onyx: It’s like they are letting you taste all of them. You get the cum, yes, but piss, piss is something that makes you feel like they are using you like you should be used. As a dirty pup, being their urinal is like being owned for that brief time. It also means more to come. To smell like them and drink them up, it’s a great thing I enjoy every bit of it. For that small moment in time you are nothing but a hole to be used, and that alone gives me so much sexual satisfaction.
MasterMarc: Does the fact that society sees piss as dirty—a natural bodily waste we typically hide—have any impact on your thrilling attraction to it?
Onyx: Not really, I still pee in hidden places all the time. People may see it as dirty, but to me it’s a dirty that I like. And they don’t have to like it, I don’t judge them for it. And they won’t judge unless they knew haha. I do wish pissing in public happened more often though, I think that would be very hot and I would enjoy it so much.
MasterMarc: Does piss take on a deliciously humiliating effect for you?
Onyx: In some settings it most definitely is, and I like it when I feel that way, like I’m just a toilet for their piss, it’s such a great feeling. And sometimes it’s not, and I like it too when it’s more a mutual thing, then it’s just plain fun. Which is also amazing. But when I’m being used as a urinal, I’m just a hole, and that makes me so happy, it’s like a treat to get his piss like I was a good boy.
MasterMarc: Do you crave the thrill of being exposed as a piss fag in clubs or at parties, soaking it all in for everyone to see?
Onyx: I haven’t yet… I’m working up to that but that is definitely a goal of mine. It’d be so hot being in the middle of guys using me like a total piss boy. Non-stop for hours drinking it, having it soak my clothes. So many things I want from it. Just to be used, it would be probably the best thing ever.
The Ultimate Urinal: Insatiable Desire
MasterMarc: If you were strapped into a toilet, blindfolded, as a human urinal, would you crave any other sexual action, or would you simply revel in that moment, even without seeing a thing?
Onyx: I wouldn’t need it but I would definitely want it. I don’t need it ’cause in the moment that’s what I’m there for, to be used as a toilet, nothing else, after all I’m a dirty toilet fag in that situation. But I would want it, I mean who doesn’t want a nice load or 20 in them? It just feels so nice, plus after loads means more piss, even better!!



MasterMarc: Unfurl the raw details, boy. Tell us a little about some of your most scorching piss experiences.
Onyx: So after my first experience, we definitely made it a regular thing for awhile. The second time we got together he wanted to meet me at this park close to his place. We met up and went to the restrooms at the park, there he had me get on my knees fully clothed and he pissed on me there, then we walked to his house. I was soaked, felt so good. There in his room I waited for him to come back with some water, and when he came in he started to piss his own pants putting my face in his crotch. Eventually leading to fucking me good and then pissing down my throat. The third time we hung out he brought a friend to help him use me. His friend pissed down my throat while he piss-fucked me. It was so amazing, I was in heaven. After he piss-fucked me and pulled out, the piss and cum started to come out and he put my face in it, I loved it!!
Beyond the Golden Shower: New Filthy Frontiers
MasterMarc: Hehe, you truly seem to be a deliciously filthy guy. Do you still have other realms of dirty play you’re burning to explore, or new desires you want to unleash in the future?
Onyx: I’m still discovering more of my dirty side so as of now I’m open-minded to try anything. I don’t know what it will be but only time will tell. Definitely gonna be a dirty boy for life though. I love every bit of it.
I’ve been wanting to lick up the piss that came out my ass, I think that would be hot. Sweaty smelly ass has intrigued me, but nothing else as of now. Maybe it will progress, who knows.
Onyx has plunged us deep into his world of unapologetic filth, revealing a primal lust for piss, sweat, and ultimate utility. His raw honesty about being a “cumdump, pisslover, and faggot” is a testament to the thrilling depths of human desire.
