The above are in reverse chronological order. In line with my quest for the biggest, heaviest tits...
I've said 60% ass as over the years my interest in ass has finally eclipsed tits. Possibly because my partner is 60% ass/40% tit (both huge). It's good because it's easier to find women with huge asses rather than huge tits.
I can never get enough tits or ass. I've had a couple of 400lb women but would love to try bigger! The more curvage the better. I just love drowning in all that flesh...
