Biggest that has been inside my wife's pussy and asshole is 10 inches long, 3.5 inches thick and belonged to her long term Dutch playmate.
It took a day or two for her pussy to tighten up after each pounding from this gent.
Me trying to fuck her straight after the two of them had a rough banging was futile, my little 4 x 1.5 inch weiner was a loose fit.
Below picture is her naturally tight pussy in its original state.
