As he guided his cock between her legs, I knew that this was the moment I should do the right thing and say "Hold on,you need to use a condom", but I...did not speak. I sat watching as the this total stranger nudged the big, purple, tip of his cock between my wife's pussy lips and with a firm but gentle push,penetrated her. Elaine did not give any response as Dimitri pushed again, getting deeper inside her. I found I had been holding my breath and I suddenly scked air in and was almost panting. Now Karen's expression became less ambiguous, and Laura realized that this would not be a chaste encounter after all, as she had predicted. Sparks were already flying."Will you join me for one?" Karen said boldly."Let's have champagne instead. I've got a bottle in the refrigerator. It was left over from a wedding party we had for a girl at work. Let's share a bath and a glass of champagne, how does that sound?"A slow smile spread across Karen's face. "You better get the mop too," she murmured. I was at the end in a very short time.When Onyx realized what was happening, she pushed her friend back and grabbed me in time to have my last real spurt land on her lower lip, and a few dribbles fall to her tits. When she saw both of us staring at the cum spattered on her, she sucked her lower lip and wiped her breasts with her fingers, licking them clean.I probably would have dozed off if my phone hadn't started ringing. I scrambled out of bed and got to it just before it went to voicemail.. I turned to head in but recognized a car approaching the RVs from the other end of the lot.I thought to myself, Nothing like having your mother show up right when you’re trying to get into the mood.I could see the amused look on her face as she drove up.After parking and getting out, my mom said, “My, if it weren’t for the hair, I would have sworn it was your father standing there. Is that one of his robes?”I said, “No. Adam ran and got it for me from the mall this morning.”I looked down, then.
