Fergie? Pamela Anderson? Scarlett Johansson? Eva Mendes?  Sophia Loren from the 60's?  One can daydream..Any other suggestions?

Which perceived gg is really a ts?  

just guessing.......jamie lee curtis.

No, Oprah

wait wait wait......... they already have a penis

now that would be funny!

Great question!

I think the contrast between the sweet, feminine, petite with the big thick dick is VERY HOT!

My dream girl would be Kate Hudson with a nine inch cock (very thick) and she would be an agressive top! I would be her bitch forever.

Or maybe Phoebe Cates when she was eighteen. Remember the red bikini scene from Fast Times at Ridgemont High? It would have been so cool if she had taken off her top and then taken off her bottom and exposed a huge dick! Judge Reinhold would have cum even harder!

My other nominees are: Heather Locklear (when she was in her twenties), Goldie Hawn (in her twenties) and Meg Ryan (in her twenties).

Preferably all at the same time!

PS
I think your suggestion of Sophia Loren in her prime is great, that beautiful face and those perfect natural boobs combined with a huge cock would have been amazing!
