I read a bit about consensual and non consensual blackmail and since then I literally can't stop fantasizing about being blackmailed. I've never even sent nudes before (I've posted nudes of myself without my face though) and the idea of being forced to perform on camera for a stranger really hot. Ideally it would be consensual(at least at first) but there would also be no safe word.
All I'd need to do is send a nude pic and a short nude video (since it seems easy to make deepfake nude photos but not nude videos) with my face in it to a trustworthy stranger who's using a VPN/proxy/whatever along with my Instagram username. Then I'd tell him that I want him to screenshot my followers list(so I can't private my account if I change my mind later) and threaten to share the nude pic with everyone if I don't do what he says. I'd tell him to keep blackmailing me even if I tell him "Stop, I'm serious, I don't want to do this anymore, safeword, I'll go to the police, they can trace your IP address(no they can't I told him ahead of time to make himself anonymous so I couldn't change my mind mid blackmail and try to have him traced so he'd stop blackmailing me), this is revenge porn and is illegal, I'm going to ghost you now please don't share my nudes while I'm gone, my phone is broken and I can't send any more nudes, etc).
I'd tell him beforehand how long I want to be blackmailed for and what kinds of things he can not ask for (don't ask me to send you money, don't ask me to do anything illegal, don't ask me to hurt myself, don't ask me to have sex with anyone, etc).
