Wife Seeks a Male Friend for an Intimate Affair

The man's wife seems quite unhappy. While she's generally satisfied with her sex life, she's been longing for something new for a while. It's not that the sex with her husband isn't good or anything, but she'd love to have a threesome with a friend from the house. Well, the husband is hard to convince, but when she suggests a threesome with another woman, he's all for it. Easier said than done, and promptly, the wife is kidnapped by two men.
