Sis knew what was coming and she closed her eyes. Her right breast was his first slash and it popped like a ripe melon as his blade sliced clean through to her ribs. The shock to her mammary meat made it feel like it was freezing. She bit her lower lip as he screamed in rage. She was the focus of his fury but not really the cause. Nevertheless, when her left breast was cleaved it burned like fire and she gasped. Before she could get out more than the start of a pitiful wail, the blade plunged into her side below the left arm. She watched as he drew the blade diagonally down across her belly. He released her neck, falling back and watched her try to hold her composure as her guts spilled out between them. He felt as if he had taken vengeance for his mother as he took glee at the wreckage he had done. He glared at Sis' face. She did not meet is gaze, she merely struggled to remain erect, to not fall and give him the satisfaction of humiliating her further. He saw the hurt in her eyes as she held back tears. She still loved him and hoped he had love for her. He dropped the knife, now regretting his rage. He reached for her and she collapsed into his arms. Physically she was going to be fine but her spirit was dying. He laid her down and placed her guts in her belly. He offered her his cock to drink from but she showed no interest. She was healing, but didnt care. He spent the night caring for her and when her wounds had closed she was responding to his attempts to excite her. That night for the first time he did only things to pleasure her and by morning she was so needful of him, she drank from him until she could no longer swallow while he tongued and suckled her tender mound. When she was done, he held her tight and they slept together until dusk.
