A Queens man was busted for flashing a teenage lifeguard at a Long Island pool, police said Monday.

Wilson Kenney, 33, of Springfield Gardens was sitting on a bench at the Forest City Park Pool facility in Wantagh on Sunday around 4:50 p.m. when he began to rub his groin area and exposed himself to the 17-year-old lifeguard, cops said.

The long-haired, partially balding man, shown in his mugshot with a blank stare, was arrested and charged with public lewdness, cops said.

Kenney was expected to be arraigned on Monday at First District Court in Hempstead.
