BBW Clubs, SSBBW and BBW forum

What's good folks. I'm 6'0 230lbs. About to be pulverized by an SSBBW next week and don't know what to expect. I can tell you what's on the agenda, facesitting/squashing, face farting, breast smothering, head scissoring, butt dropping to the body and face till possibly passed out. Any professional advice I should take. The ssbbw is about 430+ lbs about 5'4 and I also have work that night after our session is over.
