Getting turned on by riskier anonymous sessions

[BritishCumdump]

Over the last few years my sexual needs and the risks I've taken have increased a lot and I want to ask you guys if I should be worried and if I should try to reel things in and be a bit safer. The way I see it, I've been really lucky so far for nothing bad to happen to me in the situations I've put myself in but I know it might not last forever, and as risky as the behaviour is I don't secretly have a desire to be hurt or worse. Ideally I'd like to get a boyfriend or local master who could look out for me and get off on the scenarios I crave but that's not happened yet. 

First it started with just needing guys to fuck me, I'd kinda vet them so it wasn't ugly guys or creepy guys. Then it ended up specifically needing guys to breed me and cum inside me. Then it was me needing anyone's cum inside even if they didn't fuck me. I didn't care what they looked like or their weight or age, I didn't ask for pictures. 
My desired and regular way to have sex for months now has been as a blindfolded cumdump, telling guys my address, leaving the door unlocked and waiting in the bedroom on all fours, ass up, blindfolded or hooded, hearing them let themselves in and having them use my ass and leaving afterward, sometimes without a single word said outside of grunts and moans. I've gotten massively into chastity and having my cock locked up when I meet so that I can't jerk off or be played with by the guys that fuck me, my only pleasure coming from knowing that I'm being used and enjoyed by strangers and the occasions when their cocks brush against my prostate. 

Recently this scenario has escalated more and more to the point where I've got three different regulars where when we meet it's with me in almost full sensory deprivation. I'll be ass up on the bed, sometimes with a plug inside my hole, a ball gag in my mouth, cock locked in chastity, earbuds in playing music or cumdump hypno music/instructions from my phone so I can't hear anything. And then either blindfolded, hooded, or in gasmask with poppers inside the filter. 
On the side table will be my toy collection (including my biggest dildos and plugs), poppers of varying strengths, towels, and lube for fisting and toy play. And depending on how much I trust the master, the key for my chastity cage. 
This scenario has turned me on so much every time I've done it but I know there's even more risk in it than anything I've done before. 
Like the only way I feel I could escalate it further is to be tied up but as it stands I guess it's entirely within the master's power to do that to me when I'm in that situation anyway, they just haven't yet. 
The way the scenarios have played out so far have varied but have always been the hottest thing. I'll get a message from the master telling me what time he'll arrive, I make sure the door is unlocked and that before that time I have the earbuds in and sound turned on, the hood on, and am there ready and waiting, sniffing poppers hard until my head is spinning while I'm left to my own thoughts, preparing myself for anything, until I sense something in the room or feel hands on my hips. Then maybe a tongue in my hole. Sometimes though with the more brutal masters they'll just go straight into it. Thrusting their big cocks into me in one movement, no build up or foreplay, just immediately balls deep and pounding me until they cum as far as they can into my guts, owning their property for the night as quickly and as brutally as possible knowing that they've got time to recover while they play with me more. Unless I feel the warm seed shooting inside me I have no way of knowing when they've actually cum as I can't hear their gasps. A lot of the time they'll push their faces close to mine and I can feel their breath and when they're saying something but I can't hear it so I imagine they're just saying the sickest things and their most twisted fantasies to me as they slam into my cunt. 
After the first or second load they'll start toying my hole with things, mostly they'll play it safe and not go for the biggest, but there's an excitement in trying to guess what toy is being pushed inside me each time, one of the masters is particularly brutal, he's poz which turns me on a lot anyway, but he'll peg me with my toys, fucking me with them like they're his own huge cock before moving onto fisting, ending up with him punching out my cunt and trying to doublefist me. He hasn't managed it yet but being there helpless on the bed feeling a guy trying to force two hands inside you is just the hottest experience. Every time these sessions are the hottest thing and the masters and me are incredibly satisfied but I wonder about how much could go very badly with them. 
For instance, with me entirely vulnerable like I am, they could easily slip me something, drug my hole or slam me, they could force my biggest toys into me without me being ready or lubed enough, they could just straight up hurt me or worse. What if they just took the chastity key or my phone and blackmailed me to give it back? 
And I don't think that's what I get off on, I don't think it's the risk, it's more the control and the surprise that I get off on if that makes sense but it's crazy that I've been so lucky so far and maybe I should reel it in. 
One time I had it where a master came in and I felt his hands on my hips as usual, but then I felt hands on my face as well, removing my ball gag and sliding a cock into my mouth, and there I was getting spit roasted by the master and a total stranger he'd brought with him. The session was fairly long and I don't think the stranger stayed for the full thing but I never found out who it was or whether he bred me or fisted me, it could have just been the master's loads I felt spurting into my guts a few times, but I like the idea that when the fisting started it was churning multiple guys loads inside me. 

So yeah, what do you think? Do I need to stop these kinds of sessions before they go to far, or are there better measures I can put in place? Even better please turn me on more by telling me (either here or in DM) whether you'd enjoy using me in this way and what you would do in my masters' place.
