An American in Prague (1997)

All-American jock, Chance, arrives in Prague to audition for a forthcoming Bel Ami video. Always-horny Johan Paulik is enlisted as his tour guide/companion. Since Chance doesn't have much interest in experiencing Prague's rich cultural heritage, the two guys decide to thoroughly explore the vibrant nightlife. Over the next four days, Chance and Johan travel the distance from being strangers to close friends, wasting no time getting acquainted. They start by playfully teasing each other sexually, then journey into the oral realm, detour to a wild menage-a-trois, finally ending up with a pulse-pounding fuck in Johan's bed. Along the way there is also an exit into voyeurism as they watch Johan's neighbor have sex with the hot trick he brings home.
