So , the girl is taking an airtight in missionary position and meanwhile she strokes 2 or more dicks on her right side ( could also be left - but that happens much less ) . Basically it´s a departure from the airplane position ; because the hornyness gets intenser when the gal is leaning sideways to grab her cocks -- it brings more horniness ( and the girl gets more inclined to make double-blowjobs ) .
One of the set-ups is when one guy sits or lays half sideways ( 90 degree ) to the girl on the left side ; in this way he doesn´t take way space by standing around and her gives the girl a lot more room to move around .
The other one ( only 4 guys ) is when the 2 guys are not both standing on either side of the girl , but one of them stands in front and the other one more on the side . Now the field of action of the girl wll be automatically focused on one side , instead of turning equally to both sides , without any focus ( if the guys were both on opposite sides ) .
Unfortunately , I see this not happen frequently enough in the scenes , even though they feature 10-15 guys

The camera-man almost captures the foot ...
