25 Days of Gays: Mulligans (2008)

Mulligans was written by its star Charlie David (Judas Kiss, A Four Letter Word, Kiss the Bride). He plays college student Chase, who is invited to stay with his best friend Tyler (played by Derek Baynham) with his family at their vacation home. While there, Chase and Tyler's father Nathan (played by Dan Payne) soon find themselves carrying on an affair that threatens to tear them all apart, as long-hidden truths come to light. All three actors appear shirtless, with Charlie & Dan also showing rear nudity as their characters go skinny-dipping. Luke Stewart is also shirtless playing a swimming instructor that gets ogled from afar by Tyler's mother.
