My husband and I had been married a couple of years when his college roommate joined us for a weekend in Las Vegas. After a very long day and several drinks, my husband talked me into a threesome. His friend was very shy and had never been with a woman. My husband insisted that I strip for them so his friend could experience "everything". He instructed him on how to touch me. When we got in bed, they took turns on me in every conceivable position. The next day, I was very sore and very satisfied. It was a tutoring session that I will never forget.
