Three (1969)

Three (1969) follows two male friends played by young Sam Waterston and Robie Porter who are vacationing in the Mediterranean when they meet a sweet English tourist. They all start traveling together and falling for the young lady, but they vow to keep thing platonic or face a disastrous trip. Robie Porter looks amazing in his wet swim trunks that show off his package while Sam Waterston opts to take it all off and show his tan lined tush before jumping into the water. We'd like to get in on this action and be their third!
