Black Widow (1987)

Erotic thriller Black Widow (1987) follows a federal investigator who believes he is on the trail of a very different kind of serial killer. In this case he is tracking a woman who goes from wealthy husband to wealthy husband killing them, collecting their fortunes then moving on. As he gets close to her, he finds himself being pulled into her seductive web.

Sami Frey shows braves the water with the Black Widow herself when he strips nude and has a little naked fun in the pool with her. As they swim around we get a nice look at his flexing, impressive glutes. A few well-timed presses of the pause button also shows off his balls as he does some unique swim strokes.
