Think back to a time before the ever-proliferating world of pornography had morphed the female orgasm for mankind into a series of possessed screams of 'YEAH' and 'OH GOD'.
Can't? I know, it's hard (no pun intended). Well, the following clip may help you.
Presenting, the first ever female orgasm in film history - and it is as real as it is classy (yep, we're talking about the 1930s).
Also, it's way more SFW that one would anticipate.
This might serve as a good point of reference if you ever find yourself wondering how a classy lady from the early 1930s got down to bidness. *wink*
