Have you ever bottomed-out in the holes of some whore you were fucking for the first time? Yeah, it sucks to fire into her twat with all the force your hips can muster only to learn that her cunt is too shallow to hold your whole hog. Try as you might you'll never be able to spike her pussy until you are in it balls deep because your dick is just too big for her crotch. It's like trying to park an SUV n a bike rack. Well, better you found out right away so you can find a deeper girl.
