Horny Swede needs to see my North African gf get fucked...

Me and my girlfriend have been living together for just over a year now, and although the sex is damn fine, I need it to be even better I'm 40 years old, she's in her mid-twenties and originates from North Africa (Sudan to be precise). We live in Sweden.
She's always eager to experiment sexually, and we have had several three-somes with a male friend of ours, an incredible turn-on for me.
My "problem" is that I want to see her with more men, perhaps four or five at once, and although we've talked about this for months now, I still can't get her to make her mind up. This is driving me crazy I've become obsessed with the thought of seeing her getting her mouth, ass and pussy getting stuffed with white cock. I'm fairly certain that she can be talked into doing it, but up until now, I've had no luck. She's not shy or anything, on the contrary; we enjoy posting pics of her in different forums now and again, and she really enjoys that. So what I (or we) need is advice from someone who has been in the same spot, perhaps... Please

I forgot to mention that we enjoy trading pics with both couples and single males... We'll post our mail adress for those interested.
