uuummm...I assume you all do realize that a penis can not actually penetrate to the stomach. I only mention this because, based on some of the posts here, there are some who are under the illusion that it's a possibility. Then again, maybe I'm just being silly...nobody could be that ignorant.
You don't even know how unbelievably stupid and sad you sound when you post this to every man here that is long and hard enough and lucky enough to have fucked a skinny girl in the right position TO SEE THIS PHENOMENON WITH THEIR OWN EYES IN REAL LIFE.
So if you are a man, either:
A.) your dick is too short
B.) you can get hard enough
C.) you never got a chance to fuck a skinny girl in the correct position
D.) And two above or all of the above.
And if you are a woman, either:
A.) you never had a dick long enough and hard enough and in the correct position to see this done.
B.) you never tried this with a suitable object
C.) you're too fat
D.) any or all of the above.
So which one is it?
