Girls at Lichfield do a very good job as you are kneeling on all fours.

(but maybe a bit too far for you??)
One of them, and I can't for the life of me remember her name,

gets you right on the bottom end of the table and kneels on the floor behind you..
Does a good job pulling the old boy as far back and out as she can. Closest thing to "milking" I've found.
She seems to sense your on coming climax though

because although you think she could get hit in the face, she aims the other way when it matters.
Must agree though. An actual table with a central hole would be awesome.
