I don't exactly know when was this clip taken but, it seems to me that what they are doing is in fact the only modern sex improvement they know from that time. But hey! Better than nothing right? They are doing a sixty-nine, the girl blows the cock of the guy while he lick and suck the girl's wet pussy.

US clip from the 1940s. A little too short alas, but a must see woman on top action!
