The trio of musicians seemed to pick up the beat when we started to dance. The bass player was using his bow, but the tone and size of the instrument ...eminded me of the music that had vibrated the speakers in Karen's bedroom that first night. I decided that I liked the sound of the bass. It was like Karen's body, strong and melodious."You seemed to enjoy being the center of attention," I said."Oh, Sammy, it was dreadful. I've never been so glad to see you. You're the only one I know. I'm. They did look very cute together, almost like twin sisters enjoying a lazy day in the house. Both of them had put on some clothes. Karen wearing only a pair of her boyshorts and a sweatshirt that she had stolen from me a few months ago and I knew I wasn’t getting back any time soon. Kassie was wearing a pair of my old sweatpants and an undershirt. She was still here only a few days and we still hadn’t completely gotten her a new wardrobe. I stood back a few steps, my heart nearly bursting at. "I AM !!" Oh sure."Another thump. "I REALLY AM - HONEST !!"If she wasn't my supervisor I'd thump her back. No - wait. On second thoughts not thump, I'd grab her arm, twist her slightly in front and away from me and give her one of those thigh ringing swats that make bad girls jump. Yeah sure......right, in your dreams mate. As usual I just smiled and faked an "Ow..hey." as she strode ahead of me and into the building. She probably knew my eye's were watching her rock and roll rump like a kid in. I felt how the big fat cock sealed my pussy and I felt the pressure increasing, it was an extraordinary feeling, I just lay there moaning. Suddenly the pressure was to high and the seed squirted out between the walls of my pussy and the thick cock.A moment later Ali pulled his cock out and pressed the last drops of seed out over my pussy.Then he said; "You have to lay there for 10 minutes, so my seed can work it's way into your womb!"I nodded my head and obeyed, Ali sat beside me and caressed.
