The joke is that he is under her skirt in an elevator.
I wonder if they are laughing because they are in an elevator doing this or because it is funny that he would lick her vagina. This kind of behaviour seems ordinary but I wonder if they don't do this, these boys. All of these boys. Not liking it because it tastes of flesh and juice. Not liking it because it is too intimate. Not liking it because there is hair. Not liking it because that is where we bleed from.
The audience laugh and I do not. It is not funny because I like to be the recipient of this kind of attention, not all the time, but some of the time. I wonder how many head jobs, how much spit or swallow, how much hand on the back of the head a woman has to get down to before a man can kneel and put his mouth to her and not snicker.
