Love Triangle

Here's a true story for your entertainment. One of my friends has been involved with a girl for about three years now. He met this girl at K-mart, where they both worked together. At first, he felt that the girl was just another fling. So he attempted to use her for sexual gratification. In so doing, he asked her how she felt about a threesome. At first, she was opposed to the idea, but after much coaxing, she agreed. The plot thickens: my friend invites his best friend at the time (also one of my best friends) to join the party. They took the girl to our highschool parkinglot where they engaged in the threesome. The girl would perform oral sex on one while the other would "hit it from the back." Then, they would switch. After that night, however, my friend continued to talk to the girl. Currently, he is in love with her, and is getting married to the girl in May. Its crazy because he asked his friend that was involved in the threesome to be his best man. He also asked me to be one of the groom's men. However, Both the best man and I are opposed to the marriage. Long story short, there may be several objections during the ceremony.
