My girlfriend and I had a three some with a friend who I didn't think would be a threat.. until she ripped down his shorts and his HUGE LONG COCK FLOPPED OUT. His cock was 11" and I was definitely wanting to call it off but one thing happened after another so fast that I was totally shocked and didn't know what to do. I hadn't ever had a bi experience before and my girlfriend forced me to suck on my friends raging hard cock. It ended up being a really hot experience but I think if it was just a straight threesome it would have been horrible.
