So I was stalking a new smut rp, and I stumbled upon one of the roleplays. I was sorta curious to see what it was about, so I read a few smut scenes. Then I found this. (March 18, 2016 at 5:30 comment)

And I was like, "oh my god what the actual FUCK--"
So I took out a ruler and confirmed what 5 inches looked like.

(the black thing is equivalent to 5 in. apparently.)
That dude's humongous DICK is 5 INCHES THICK.

I'M SURPRISED HOW THAT CHICK ISN'T SCREAMING BLOODLY MURDER, BECAUSE THAT'S THE PAIN YOU GET WHEN A BABY IS HALFWAY OUT OF YOUR VAGINA.

Then I measured what 18 inches looked like.

(left to where the pencil blocks the rulers)
And I'm like "Holy shit how does he poop right"

Anyways, I don't think that it's normal to have a vagina that fits 9 inches of cock. Idk, but I'm pretty sure it fits up to 7 inches...
