This below-the-waterline shot of a very nice ass in the swimming pool is from a little-regarded Russ Meyers sexploitation/horror flick from 1968 known variously as Finders Keepers, Lovers Weepers! and Null Null Sex:

There’s a cast of many and the plot summaries are awfully summary, so unfortunately I’m not in a position to specifically credit that excellent butt to any one of the actresses in the flick.
