Vint70s-Lvr: Muscle bears Carlo Masi and Zak Spears flip-fuck in two different scenes. I’ve been a huge Zak fan since the early 90s, when he headlined the Redemption series. Now a middle-aged daddy (like me), Zak still has what it takes to steam up a camera lens. Carlo is beautiful, ripped, and in his masculine prime. In BuckleRoos, Zak takes Carlo’s ass on a bar. In Wide Strokes, Carlo returns the favor poolside. Sometimes the pup takes the dog, and that’s just beautiful!
