Playboy: Wet & Wild 02 (1990)

Two fit blonde chicks with shoulder-length hair and visible tan lines take it outside for some girl-on-girl action. They start on a towel near the water, one lying back while the other goes down on her. The lighting is bright as hell—sunlight makes everything pop, especially the close-ups of the oral. One of them has a pierced belly button and slight sunburn, which somehow makes it hotter. The camera gets right in there, no shaky handheld crap, just clear shots of the tongue work. They switch positions later, but the outdoor vibe and the way they go at it without hesitation is what stands out.
