Cute Carter wants to get muscles like his older stepbrother’s, so after his workout he tries to sneak some of the big guy’s protein powder. But when his big buddy catches him in the act, he fills the boy in on a well-kept secret about building muscle. Turns out that cum is the best way to get all the protein you need, so the boy gobbles his older stepbrother’s dick, letting it poke the back of his throat as he bobs his head on the thick slab of meat. Then, he bends over and lets his big buddy lick and slurp his asshole before getting penetrated by his girthy boner!
