This seems to be a very common fetish in England but not so in USA. Many mistresses there advertise for male milking and shows facilities with devices for prolonged teasing, Venus 2k and others.
But I hardly find these kind of sessions advertised in USA.
I'm talking about a long session (3-4 hours) when you're tied, edged and back for 1 hour or so, then after an orgasm, just when you only want to relax and go, POT starts, and you're forced to go on until at least 3-4 cups are forcefully served.
Obviously, after the initial pleasure, being unconfortable takes place and that's just the way it has to be.
This do not necessarily need devices (although a Venus 2k or so greatly adds to the scene), but at least skilled hands and a merciless attitude (no way to escape once started).
Is this a kind of sessions too bizarre? No one have interest in these kind of fetish?

Post Orgasm Torture.
When a lady keeps stimulating you after an orgasm, when you're extremely sensitive.
Eventually going on without giving a break until achieving another release

I feel milking is very popular here in USA, Prolonged milking is more in the fantasy side. Usually man want it, but after the first one it's  over and  a no more turns into a NO MORE potentially an issue if continued .

haha it's amazing how not in the mood people get post cumming!

Women who specialize in fantasy play and D/s related play would be into orgasm control and post orgasm torture. I don't necessarily advertise for it, but it's something I love doing if it's part of my client's fantasy.

pot sounds like something i would like  very much . i will have to look into it .

OMG just watched clip of POT on Porn Hub and it looks amazing and highly erotic.  May have to find a provider into it and submit.  Yikes!!

It is both of those and also EXQUISITE torture if you are the over sensitive type - there is a good reason those guys are tied in those clips - that is from personal experience!

Holy shit those are hot.  Amber really milked that slut.  Yikes bet he didn't cum again for a week.

Ain't it though?

Those kinds of sessions are among my favorites!

I've also seen it called POST in some circles. For post orgasm stimulation torture. Same thing just another letter.
