I thank you Mark for this thread. Just like feet, this one strikes a deep nerve in me. It reminds me of the time in West Hollywood, CA (90069) that I learned of twins working for me, after I had had sex wth them. My daddy taught me to "keep my dick in my pants while at work." This I followed until I was confronted with two attractive guys that were identical twins. After sex with them they told me that they often switch off and work for each other. My dad's warning was right. I was faced with either firing them and busting myself at the same time or allow them to work under one name and pray no one got hurt. I'm sure what they were doing was against some labor law. You know that I kept my mouth shut. Why? Because they became regular visitors to my bedroom most individually. It is true that twins have a secret nonverbal language. Also true one will be more dominate than the other. I wish I could share my erotic story about them here. I had to put to paper what happened. One fantacy accomplished and never repeated. Sex with TWINS!
