well i mean as the Mister minister of slavery say their regular size would be around 13 so as we are at least around 9 it at least better lol =)
but damn yeah for comparison i'm above 16c and i reach my bellybutton so to compare with the mc as it go beyond that point i would say it could be a 10.
after yep 13 in so 32.5 cm is around the longest pp, 35 cm if i remember
so yep well better than nothing but likely he will lack some centimeter too
