Teach him who is the master.

"How dare you, it is only through me that you have power!" you yell at him. "I will see you kneel and be humbled before me," although you are not sure how you know better than to show him fear. You look deep inside the pit that is your soul and try to summon the power to beat him. You realize that a woman's, even a demon woman's, power is not in **** but in love or at least lust. You look inside the former father's mind and pull out an image of his perfect woman.

Your body takes on the form of a naked nun wearing only her habit, she is young and inexperienced, her breasts are tiny perfect peaches. Her body is slim and soft and between her legs is a thick brown thatch that hides her wet pussy. You sense that he knew and desired her.

"Oh, Father Stephan, will you please pray with me, I have sinned." The demon hesitates, it is not sure what you are. Your new heart shaped lips smile at him. It turns him on and he is no longer thinking of ****, he is thinking only of sex, and sex is your power. You lay back on the cold floor and spread your legs wide.

"Father, I have committed the sin of lust, and only you can absolve me of it." The demon kneels and he is your **** again. You call to your child in his tail and it takes on a life of it's own as it snakes into his ass. He is essentially fucking himself. It is too much and the demon falls upon you and thrusts his twin dicks into you. Had you been a human woman this would have torn you apart, but since you are now a full demon your pussy adjusts to it and it feels good..
