When New Earthling Quinn makes love to his Allurian bride on their wedding night, he discovers a few surprises. Like the fact that losing his virginity to an Allurian woman is painful. He and Xindra are able to work things out, but they realize other interracial couples on their planet face similar problems. They start an Alien Sex Ed class, but this isn't your ordinary anatomy lesson. This class is very hands-on and more than a little steamy. Xindra's friend, Mera, is the first to benefit when she meets and falls for one of their students, Trett. As an Ibration, Trett doesn't thrust during sex; his penis vibrates. That's perfect for an Oquaran like Mera, who's so sensitive she comes almost instantly and can't stand a lot of chafing. When Xindra and Quinn notice more than one of their students checking each other out, they have to wonder. Could the romance between Trett and Mera be just the beginning?
