Bikini abandoned on the deck chair, 80 year olds having sex floats naked in the pool. Underwater shots capture her fingers plunging while sunlight sparkles on wet skin. Surfacing, she straddles the pool edge, spreading wide and rubbing furiously, chanting “80 year olds having sex” to the open sky until she comes so hard her screams of “80 year olds having sex” echo across the water.
