Karina's thick, curvy body trembles with anticipation as Fernando's friend, a stranger to her, takes liberties with her breasts. He kneads her large, soft mounds, his mouth latched onto her hardening nipples, sucking and biting through the thin fabric of her top. His hand roams, cupping her pussy through her shorts, feeling the heat and wetness building. Karina's moans fill the room, her husband a silent spectator, his cock twitching at the sight of his wife being used for pleasure. The friend's cock presses against her, a tease, a promise of what's to come, as they dance on the edge of infidelity.
