We're glad you asked!
In the book, Forrest and Jenny still got after it all night, but this version was very, very clear about two very, very strange points: First, that Forrest has an enormous penis. Second, that Jenny loves to talk dirty. Now, remember that the novel is told in the first person, and Forrest no talk good. So now that you're all set up, here's a sentence no one ever expected to type: Please enjoy a graphic passage from the erotic memoirs of Forrest Gump.
When we get home, Jenny begun takin off her clothes. She is down to her underpants, an I am jus settin on the couch tryin not to notice, but she come up an stand in front of me an she say, "Forrest, I want you to f**k me now."
You could knocked me over with a feather! I jus set there an gawked at her. Then she set down nex to me an started foolin with my britches, an nex thing I knowed, she'd got off my shirt an was huggin an kissin me an all. At first, it was jus a little odd, her doin all that. Course I had dreamed bout it all along, but I had not expected it quite this way. But then, well I guess something came over me, an it didn't matter what I'd expected, cause we was rollin aroun on the couch an had our clothes nearly off an then Jenny pulled down my undershorts an her eyes get big an she say, "Whooo -- lookit what you got there!" an she grapped me jus like Miz French had that day, but Jenny never say nothin about me keepin my eyes closed, so I didn't.
The scene goes on to include all the sexual positions they try: Jenny shown me s**t I never could of figgered out on my own ... sideways, crosswise, upside down, bottomwise, lengthwise, dogwise, standin up, setting down, bending over, leanin back, inside-out and outside-in.
