Klauz Mainwart returns home to find his wife gone and a note indicating she'll be back late. Seizing the opportunity, he invites his mistress, the ravishing Carolina Carioca, over. She arrives in a sheer negligee, her nipples hardening as she teases Klauz. He devours her pussy, making her squirm, then she returns the favor, sucking him off until he's rock hard. Klauz fucks her missionary, her legs wrapped around his waist, their bodies slick with sweat. Just as they're about to cum, the front door creaks open, and Klauz's wife walks in, catching them in the act.
