My friend gave me his wife as a gift and I ended up fucking her raw

Mark had always had a secret crush on his friend, Tom's wife, Susan. He fantasized about her often and even had a folder on his computer dedicated to her. One day, over drinks, Tom confessed that he was struggling with his libido and that he and Susan hadn't had sex in months. After some alcohol-fueled bravado, Mark offered to help by giving Susan to Tom as a gift.The plan was for Mark to come over while Tom was out and"entertain" Susan. However, as soon as he saw her vulnerable on the couch, his desire overwhelmed him. They kissed passionately and soon their clothes were off. Susan, surprised but aroused by Mark's boldness, willingly gave in to his advances.Despite their intense excitement, they could hear Tom's car pulling into the driveway. They quickly scrambled to put away any evidence of their illicit activities before Tom arrived home.
