Would you be so kind to make a similar analysis with those arrows based on the attached screencap?
Thanks
Here you got it.
Important note: the girl in that pic is pressing her hand against the pelvic bone of Mandingo. This way the dick looks larger than it is. In fact is a common trick widely used here by many guys. If I do the same, like in this pic from my gallery, my dick also looks larger than it is:

Well, as I said this is the pic you posted with the arrows being the width of the girl's hand.
Also you can see that when the black girl holds Mandingo's dick without PRESSING hands against the pelvic bone her hands are closer to the glans than the one from the white girl in your pic (wich is pressed).

Despite the fact of the hand pressed we got 2.94" + 2.94" + 2.94" = 8.82".
So the sum of three hands width from the girl is larger than Mandingo's dick. So it's clear the dick is less than 9".
And bearing in mind that the girls in porn videos (specially in big-dicked porn) are TINY and PETITE girls, chances are that the HAND WIDTH from those TINY girls is less than the average hand width on adult females (2.94").
So the hand width of three of this girl's hand might be very likely less than 8.82"
