Couple things... lol
There used to be a guy on Twitter with this setup. He'd be under the table--there was draping around the edges to keep it like a lying gloryhole, with a mask on, and making a vid of the anonymous "member" dangling through the hole, and his hands and masked face in action. He'd have the cutest smile when he'd turn to the camera, with his black mask covered in "milk". Oh! And he wore small swim goggles, to protect his eyes while he watched it shooting right at him. LOL!!! It was awesome, but I've forgotten his name (something along the lines of "bull milker"). He may also have left the platform, and be why I haven't seen him in a while.
I checked out this table, and $780 + $50 for shipping??? If someone is mildly handy, they could get pretty much the same table on Amazon for about $150, plus a hole saw and staple gun, for probably under $200. In an afternoon, you could get it done, and be busy that evening. 😜
