In a secret lair, a muscular stranger in a mask awaits, his huge cock throbbing with anticipation. Captain America, defeated and bound, is forced to his knees, his powerful body tense. The masked man seizes Cap's chiseled ass, spreading the cheeks wide to reveal his tight, pink hole. With a growl, he slams his bare cock into the superhero's ass, fucking him raw and deep, the sound of flesh slapping against flesh echoing in the room. Cap's moans are muffled, his body shaking as he's mercilessly pounded by the mysterious invader.
