Looking to play out a scenario where having disposable human fuckdolls is entirely normalised, no more of a stigma than any other form of prostitution.

This has led to the proliferation of a "game" popular with groups of men where the fuckdoll has a collar fitted with sensors attached that when triggers constricts and suffocates them.

It can either be triggered if the fuckdoll orgasms. This is popular with groups of young friends like frat groups, all eager to show off their prowess. Imagine the bragging rights if you get a fuckdoll to cum when her life literally depends on not doing that. You can do anything of course but to make it a challenge it's generally accepted you mostly need to be using your cock. It's not unheard of for guys to cheat, for example using a discrete vibrating cock ring, but this is risky and needs to be hidden to avoid the embarrassment of being noticed by your friends.

Rather than having a fuckdoll each more cash strapped groups may run a train on a fuckdoll and draw lots to see who goes in what order. The principle is the same but it usually seals the fuckdoll's fate one way or another.

It can also be triggered if you don't cum before a timer runs out. This is more popular with groups like bachelor parties that want to be the recipients of a good time, there is no fuck like a fuckdoll riding you to try and make you cum as if her life depends on it - because it does. But similarly no guys want the embarrassment of cumming quickly. Some guys will even mention "winning" this on their tinder profiles, no better assurance to a hookup that you won't cum first.

While I'm imagining this as a group scenario we'll mostly focus on our individual characters so there aren't too many spinning plates. I prefer decent sized messages so around at least a couple of paragraphs, If you're keen I think message works better but also open to reddit chat, tell me what you have in mind. If this post is still up then I'm open for partners!
