There's only been two women during my dating years that could take four fingers.
The rest have been one or two fingers. With those women, sometimes I'd try a third despite her slick running down her ass and her pussy like a four-hour-running crock pot and it's, "Ow! Ow! Stop that!"
But, those two women that could take four fingers - my little dick seemed to get them off quite quickly and easily. Wasn't no fakery going on. When their cum came on, so did the trademark vaginal "cum-clamp" that most women do when they're getting their rocks off.
Ah, the clamp. In my top five of thrills.
I wouldn't invest too much concern in the matter.
