In Heat (1986)

These New York boys are IN HEAT!

The weather in New York is hot, hazy, and humid. Three handsome, horny young urban professionals rise with the sun in a hot morning session. Bodies flex and stretch through a sweat-soaked A.M. workout. A New York marathoner races into sexual delirium at the 21st mile. And into a New York night: dangerously real, sexually explosive.
