Has anyone ever came across any Gloryholes anywhere?

Gloryhole is where you insert your penis through a hole in the wall on the otherside, without seeing the girl on the opposite pleasure your cock

I watch a lot of Japanese adult video, but only encountered a few Gloryhole-inspired sex scenes in Japanese A.V., such as a girl stuck in one of those "hole in the ground"
squat-toilets with her legs spread open, while a bunch of guys mass-bukkake on her..
Western A.V. on the other hand does a lot of hot Gloryhole stuff in different scenarios.. such as the girl sitting on the toilet while she sucks the guy off..
Usually involving 1 guy and 1 girl... but it can involve a bunch of cocks through the holes, with the girl(s) sucking / fucking and pulling them off one by one

HOLE SIZE:
The hole can either be large, where you can see both balls and penis.
Or it can be a small hole, just big enough for the penis to fit through.

WHERE IS THE HOLE:
Most of these Gloryhole movies have the holes on the walls, but I have seen a few (including J.A.V.) where the hole is actually on the ground, with the girl
bouncing up and down on it.

Has anyone came across one of these GH services before?
I really want to try one of these..

In Manchester there is a 'sauna'* which has a £25 glory hole service.

A few people on UKPunting have tried it.

A lot of the punters suspect extremely old women or gay men doing it. Manchester after all is one of the biggest areas for gay men in the UK.




TBH this is the reason why MOST if not ALL public toilet stall partitions are made from thick steel to prevent guys cutting holes in the walls and doing GH.

never heard of any here in HK but of course the idea of a blow and go place is wonderful. I usually like to see the girl and do a bit of groping. I've always passed by the bars in Wan Chai and seen some nice fil hotties outside, and tempted to just go in and tell MMS, i just a blow, no drink and get it done. Heard a couple of punters did that for 600HKD. They have B&G places in Bangkok and Vietnam, it's awesome.  IN San Francisco, there are GH places or guys who post ads that just say "walk in a dark room, i suck you , you fuck me and walk away, never seeing my face" LOL

I couldn't think anything worse then putting your dick into a hole without knowing what, who and how clean the person is on the other side.
