As I came inside Kitty she cried and was kissing me, whimpering "make me pregnant Master" and "I love you" over and over. Looking at the clock it was ...ard to believe we'd had sex for 28 minutes, that was the ring not me. Kitty was shaking again through her fifth and final orgasm and each had come faster then the last. I held her tight and she held me. When she had calmed I withdrew and flopped onto my back. I looked at my sister with new eyes, she smiled at us and whispered "that was the most. Id like more than a piece, Amy said, but I guess I have to share. She got down on all fours, and I hopped off of Pete. He shook his head in disbelief of his situation, then moved to Amy and began to give it to her from behind. Thats a good boy, she said. Oh god, you know how to use that thing, dont you… Peter had his hands clenched on Amys hips, and was giving it to her good. Slow down Peter, Sara said. I want you to have something left for me! Dont worry about that, Sara, he replied. Youll. Wreck his faggot ass."I pulled out until just the head of my cock was still in his asshole. Then, still looking Sally in the eyes, I drove all the way into Dave's no longer virgin shit chute, my balls slapping his balls as I buried my cock in his ass.He let out a scream. He was shaking, shivering, and writhing, impaled on my cock. It felt wonderful. To me.I held myself deep inside, to let him try to get used to me in his ass. When he calmed down, I pulled out so just my head was still lodged in. It's going to be like removing gold from its ore to start. Then it will be like a giant and very repetitious jigsaw puzzle that needs to be assembled. If we don't succeed then it won't matter for we will have four more chances with slightly different mixtures. Are you ready?" Yes master. This is interesting."I used my hand to caress Sonya and kiss her body the way she liked. I pinched her nipples and stroked her clit and she started to respond strongly. I moved behind her and caressed her back.
