Don't make him cum yet

You pull your fingers out of his ass and he lets escape a low moan, though from relief or disappointment, you can't tell. Glancing over at Harold, you finish climbing onto the hiker, straddling his back and facing his feet, your balls rubbing along his backbone as you shift closer to his feet and grab his ass with both hands, kneading the hard muscle as your spread his cheeks.

Harold stops his pacing, his face red as he watches the two of you, a string of clear precum dangling from the tip of his cock.

"Look what I've got for you, master," you say. "Just look at this juicy ass. I know you want to stick your cock in him and listen to him scream. Don't you, Harold?" Your master makes a breathless, needy noise, but doesn't move. "No? Maybe I should keep him all to myself, then. I've been hungry for ass for as long as I've existed."
