Slowly, she began to take up a rhythm, turning into a human spring on her master’s lap. As she got used to the sensation of his phallus stuffed insi...e her, the height of her bouncing increased, as well as her speed. Before long, she was billowing up and down on his lap like a high-speed yoyo, while Isaac, not wanting to just sit there like a statue, used his lips and tongue to pleasure her jiggling tits.Holly moaned in indescribable happiness, able to let her voice ring out without the fear of. That was when she said, "Remember I have rules." She proceeded to go through them, and our creating a safe word which I honestly forget because we never used it again. Then she got to her biggest rule, the one I knew was coming. The one she introduced not so much as a rule, but a choice. "Who wants to fuck me first?" Rei asked. Josh was all smiles. "The guy who fucks me first is the one fucked by the other guy first." Josh's face turned to shock. "That's one of my rules." Josh didn't know what. She gradually went down and began sucking my boobs.The warm sensation of her mouth on my breasts made me shiver and she slowly began sucking my left breast and holding the other one in her hands and rubbing it. All these while I was enjoying the feel of her warm mouth on my breasts. My hand now moved slowly towards her lower part, slowly I separated her legs and began to rub her pussy which had become all wet. I began to play with her clean shaven pussy with my fingers, suddenly she stopped. Wow that was good!! Then I thought; good yes, but not as good as when John had done it for me. Why was that? Finally I drifted off to sleep.The next morning I met John as usual and we walked to school together, hardly a word was spoken. We went into our separate classes and the day went by as per normal.That evening we met up to walk home again, very little conversation passed between us. As we approached the old coal yard my heart started to beat faster, would he be busting for a pee again?.
