I once had a link to a vid here on tumblr where there was a kind of shack with holes where dudes could basically have their whole lower bod on one side and the upper part on the other to get fucked by strings of men. kinda looked like a restroom where men just piled in to relieve themselves in the offered holes.
it’s kind of my end-all-be-all of glory hole tbh it was so hot. I lost the link tho unfortunately x.x
I have no recs off the top of my head (other than a fic in my comp vol.7 – brofuck), but maybe somebody does
