He’s doing his duty to fuck a woman who’s friends with his wife. It’s a quiet evening and he and his wife are invited to dinner at her best friend’s house. After a few glasses of wine, things start to get interesting. His wife goes to the restroom, and he is left alone with her friend. She gives him a provocative look and whispers in his ear: „I hear you’re good in bed.” He smiles and replies, „Let’s see if it’s true.” He takes her by the hand and leads her into the bedroom, where he undresses her slowly and begins to fuck her pussy passionately. She moans with pleasure and begs him not to stop. He does his duty until she climaxes, and then they go back to dinner as if nothing happened.
