Wife got really, really turned on by Emmanuelle 2! what next?

I have fantasised a lot about my wife being fucked good and hard, by a huge cock. I don't think I could go through with it though! She's gorgeous, slim, and very, very straight. doesn't do porn! No toys etc.

I got her to agree to watching 'Erotic Film' and she'd never seen Emmanuelle even, so I d'ld Emmanuelle 2.

She has never been so hot. She loved the scene where Emmanuelle is watching the old anime movie threesome about a black cock, and a woman with a strap-on, and the black dancer is caressing her - v hot.
She loved the sex scene with the tattooed stranger at the polo club - very hot. And went wild with the massage parlour scene and the unfortunatley short sex with three men!!

What else do you recommend we watch?
