My Dad's Best Friend

When 26 year old Marcus and his family gets invited to spend the summer holiday at his dad's rich best friend from his college days, he is reluctant to go. But the moment he meets Nathan, his dad's best friend, there is an instant attraction between them. But that's insane, right? Nathan is years older than him and, to make it worse, his dad's best friend. Oh, and there's one more problem; Marcus and Nathan are both straight.
