As the second of the three months drew to a close, Celeste started exhibiting changes. She would enter fugue states that would last up to an hour, and...when she came out of them, she had no memory of ever having been gone. Entire hours vanished for her, and she had no memory of what’d had happened while she’d been away. Her vision started to deteriorate, and after examining a medical text on the matter, I concluded that she had less than three weeks to live.When she was lucid, Celeste and I. The two of them kissed as Patty lined Ben's cock up with her already wet pussy. There were no panties to get in the way.Patty did all the work, grinding and bouncing in Ben's lap until he gave her insides another sperm bath which made her cum. She headed off to the bathroom for a shower and suggested he join her, "since he was so dirty." He again filled her up while she was bent over in the tub.---Ben allowed Patty to stay "for a while," making sure she knew she had to look for somewhere else. Suddenly, she felt him move behind her; so close but not touching her as if he was torturing her. She wanted to turn and grab him, holding him close, kissing his lips and removing his clothes to have uninhibited sex. She was drawn from her thoughts by his words. "Turn around." She jumped at the sound of his voice in the silence of the room; it was if he had screamed those words in her ears. She turned slowly to face him, barely remembering to lower her eyes. She looked down at his shoes, black. I make sure to turn her over and move her around often so she doesn’t have sores. Our mother left us soon after she was born. She didn’t want to take care of a mentally retarded kid. So it was just Daddy, my little sister, and me.That meant I took care of her. I bathed her, dressed her, fed her, and played with her. Daddy did a lot of the work too. He fed her sometimes. Other times he played with her. The first time he came into our bedroom to play, he wanted me to stay and.
