I began licking the pinkish skin behind his sack, working downward in short vertical strokes closer and closer to his asshole. If I had any qualms abo...t what I was doing I don’t remember them now, I must have been totally in the moment. Closer I inched to the puckered hole. The smell was still clean and soapy, so I kept going, and touched the tip of my tongue to the opening. Matt flinched, and I licked a little harder. He whimpered again, and I licked more vigorously. The taste was not at all. Then he was planted deep and her body was filled with a liquid heat. She could feel every pulsation as he unloaded his seed into her. “No! No! No!” She screamed as she collapsed forward onto the table, her whole body convulsing. “No l can’t,” she sobbed, “why….why me.”She could feel him pulsating inside her, firing more and more of his seed into her belly. She cursed her own body, cursed Frank for years of unsatisfactory sex, cursed this beast that had violated her, humiliated her and taken. I felt the tingles of pleasure in my crotch as she continued to play with me while I watched dreamily as his manhood continued moving between her legs, never entering her, merely rubbing her pussy."Don't worry sissy, this is Doc; he's here to check on you to make sure you are ok. I let him in cause he told me Daddy had called him and told him to come over. He needed to check our temperatures with his 'the momanter'. He's warming it up right now." I nodded my head still not comprehending what. He pictured his sister noticing him and turning to give him a better look at her front side. He pictured her perfect tits being rubbed while he watched."Oh yeah." he moaned. "Just like that. Rub your perfect boobs for me." He started to rub faster, really getting into it. Then he imagined Angela getting out of the shower and walking up to him. Then she dropped to her knees and took him in her hand. She jacked him off and looked up at him with those recently discovered to be amazing dark blue.
