The time had finally come. His sister told him that their daughter was beginning to show signs of weakening. She was past due her time of opening. At the age of two her breasts were forming and the lack of semen was affecting her mind. She was starting to have seizures and it would require a drastic yet enjoyable remedy. He told his sis to send her to him in the barn...

The little one walked into the open barn. Her daddy was hanging ropes when he saw her. "Come here Pepper, daddy want's to talk to you"
She walked close and inspected the ropes he was working on. One had a large gleaming hook. She liked the look of it.
"Do you know why mommy sent you out here, honey?"
She nodded "She said you were going to make me better. Like you did for her"
"That's right. You see, our family is different. We are not like other people. My daddy was from a different world. Our bodies work different, have "needs". We are so much so that we cannot do body things with other people. We would hurt them. So we are our own kind. Your grandpa was not mixed so he was able to have us with grandma, who is a normal human."
She nodded but was still apprehensive about what was to come. He smiled at that, "Your brother is to be for you and your sister, but he is not ready enough to help you so I must" As he explained he removed her dress. He was wearing jeans and no shirt and he caught her staring at his bulging crotch. "Do you want to see what daddy has there?" she looked up guilt on her face. He had caught her staring at his bulge lately.
"It's ok. It's swollen up for you anyway. But first we need to attach these to your arms" and he tied a rope above each elbow.
"Now Pepper, daddy is going to raise you up a little" and he pulled the other ends. The pulleys overhead squeaked as she raised. She squealed as she felt her tummy flutter and then she giggled. He walked around behind her and with his arm round her belly, he lifted her bottom level with the hook tip.
"Pepper, I'm going to start now so you must relax and trust daddy"
"Ok daddy"
He put the tip against her bum, then thought better and wet her hole with his tongue. She laughed and wiggled, "Oh you like that?" and she laughed more. He saw for bum relax and open and he inserted the hook three inches. She went rigid, gasping. With his right hand he massaged her ass until her sphincter relaxed again. He kissed her backside and ran the hook in until the loop was against her middle back. The he gently lowered her bottom. She was hanging perfectly by her arms with the hook snug.
"This is going to seem scary at first but it is necessary for this to work." She was trying to hump the hook, good girl.
He grabbed the third rope and jerked it hard. The hook rotated in her penetrating her bowels and protruded out her back lifting her bottom again by her pelvis. She panicked and kicked and screamed and as she did he stabbed her shoulder with an old screwdriver blade she started to shake as her affliction took over. He knelt under her to quickly catch and swallow her dripping blood from the blade. Her blood made his cock harden like steel. He opened his jeans dropping them at his feet and taking her head in his hands he held it firm as he entered her mouth. He shoved until her palette split. Again he thrust and tore through her cranium. Once more and her scalp popped open splattering brain and blood. He fought the urge to burst her skull clean off and pulled back inside. Once he was in her warm mush again, he drained his cum in her head. He waited for her head to fill and he withdrew. He held her jaw closed and covered her head wound to retain his semen. She hung utterly motionless and lifeless for three full minutes. He began to weep for her when suddenly she thrashed and and gagged for breath. Cum blew from her throat and as she gulped for air he lifted her from the hook and untied her arms. He held her for hours as she slept and he watched her mend. When she woke, she sat up, looked at his cock next to her, and then told him point blank "I'm hungry daddy". He nodded, laid down, and let her lay on his chest to feed from his dick. He listened to her gulp,gulp,gulp as he suckled and explored her fresh holes. Her appetite was draining him until she came in his mouth. Then his urges rose...
