"Would you like to see what I look like? And touch me, too?" I asked and he nodded enthusiastically so I asked him to unbutton my blouse which he did ...then slipped off and put it on his chair. We had made the same offer for his questions as we had with Andy but he, for whatever reason, had few questions so he'd not seen me naked.I turned my back to him and he eagerly got my bra unhooked and I let it slide off my arms."Oh, Mom, you are so pretty. You really mean this, we're really ... you know,. "You are going to make me come in your mouth again, bitch… go easy”That bastard said to my sexy wife. Then Ana surprised me by telling him:“I love your black cock. I want you to fuck me. I will do anything you ask."Fred then grabbed my wife’s hair between his rude fingers and made her stand up. He held her by the waist as Ana straddled his torso. I could see her soaking crotch. Her pussy lips were dripping her sweet juices…Then I watched Anita taking that magnificent black cock as she aimed it. I realized that this is the moment and I told my boss that I had received an urgent call and I will be back in 3 hours and I wanted my wife to accompany my boss. My boss was happy, but my wife was a bit reluctant, but I explained it to her that it would be bad manners to leave him alone, and she agreed. I left the restaurant and I left them alone.

Later I concentrated on the smaller fragments of diamonds and cut those up until there was only coarse sand left.Dad was home late after going to some industrial supply shops to find a small precision lathe. It was delivered the next day and mom wanted to know what was going on. The word 'secret' was as good as waving a flag in front of an enraged bull but I refused to answer. The lathe was set up and I pictured the crystalline structure of each diamond and ground one against the other till all.
