Sex club newbies

My wife and I have been married for 20 years. Our sex life has been pretty ordinary. After a year of crazy sexual awakening we decide to go to a swinger club in a nearby city. We are shy and feel lost but are very excited. After a drink we settle in and undress. People around us are having sex. We gradually give in for the excitement and start to fuck. Hot people around us watch and then join in. We end up in a messy orgy.
