Years ago, my (now ex) wife, a bi couple, were intimate friends with another bi couple. We would get together about once a month over a 2 year period for crazy, no holds barred sex. During these hookups, two cocks explored and came into 4 mouths, 2 pussies, and 4 assholes. Vaginal and anal creampies were eaten by all, along with lots of kissing, cum and other bodily fluid swapping.It was gloriously fun and hot... And that is how 4 people got sick from e-coli. .
