Going To Mexico With My GF, Hoping For A Gangbang.

I've been dating my girlfriend for 5 years now. We started dating in college and at first it was just booty calls. My roommate at the time and I tag teamed her more than a handful of times, so we aren't strangers to a threesome, but we havn't involved anyone else since college. Next week we leave for Cancun, and we have talked about it and if we find 1 (or maybe 2 or 3) other willing guys, we are gonna get her spit-roasted again or possibly gangbanged.
