Let him proceed

You’re too embarrassed to admit it, but you like the way it feels. His hard cock throbbing and sliding in and out of you, the pressure on top of you and his panting and moaning, disregarding you and not thinking even once about you but simply using your hole as a tool to get himself off. You do your best to pretend to keep sleeping. He humps your ass, penetrating you again and again, balls slapping against your cheeks as he pleasures himself wantonly. Finally, he stiffens up and unloads his semen into you. Happy with himself, he stands up and whistles as he walks away the direction you came from.
