When I first met my husband so many years ago, and after we had only been together a few weeks, I mentioned that I could fancy one of his friends , so he organised a 3sum for me.
A few weeks later an old girlfriend of his who always was hanging round,( he had known her for a few years , she always broke it off, and then months or even a year later she would pop up, wanting a good rough fucking) had invited us the her new flat, she cooked a meal and it was easy to see how on heat she was, and she had drunk a bit more than was wise, and kept making advance to him even though I was there.
Eventually he whispered to me, he really should give her a good fucking (especially as this time he had dropped her for me) and as I thought it’s only fair because of the 3sum I said ok.
So he just grabed her, striped her down , slaped his cock in her mouth, and then fucked her hard and fast in many positions on her sofa.
I just stood and watched, I did get aroused, but also very jealious. But I did enjoy watching him perform, so comarnding and dominant.
After we got back home he did the same for me, I got a really good pounding, and loved it.
