Though this isn't ER, the two nurses in this ward are specialists in relieving acute stresses in the groin.
That's a good thing; the doctors and patients seem to be suffering from a case of backed-up sperm and the pair gives them a satisfying prescription of gangbanging. The nurses think of their patients first and don't bog themselves down with jargon like distal and proximal, supine and prone -- deeper, faster and harder seem to be their favorite diagnostic terms. They fuck and suck like champs, upholding the pride of the medical profession and Euro-girls everywhere.
The girls are trained experts, sucking while fucking and taking their orifice-stuffing (which includes a few d.p.s) nice and loud. The treatment ends with the nurses taking loads orally.
A classic example of the gangbang genre that will be dissected and examined, post mortem, by other directors for pacing and timing.
