Secretly fucked behind his back! Did he notice us?

OMG that was extremely risky, even by my standards. But what are you supposed to do when you're suddenly overcome with lust and just want to get fucked? I didn't care that he was actually gambling and should have just turned round at that moment. But one thing at a time, I had a visit from a pair of good boyfriends and when the first ones left, the other two made themselves comfortable on the sofa to play another round. I had been tingling between my legs all evening and was already so horny that I decided to take my next best chance and let my charms play a little when one of them disappeared into the kitchen. The actual game quickly became a minor matter and the real, extremely hot game on the kitchen table could begin. Luckily he had headphones on so at least we didn't have to be completely quiet, although I really had to pull myself together not to moan through the whole apartment. It was the ultimate thrill and simply unbelievably hot. I can't imagine what would have happened if he had turned round. Would he have gone along with it?
