"When you say cast aside..."
"I mean remove. Destroy. Eliminate. Purge. You understand? You will be gone. Dead."
"Oh... but why?"
"What do you think the term sacrifice means?"
"I get that, but I don't know... can't you just put me into something? Not as your daughter though."
"Then what?"
"Mmmm... how about your pussy?"
The Goddess was silent for a moment. "You want to become my pussy... Ha! You are quite interesting human. I have had numerous hosts before, but you are the first to request this accommodation. Fine, I will tell you what. Submit yourself entirely to me, and you can not only be my pussy, but I will let you be my ass and breasts, and too. You can be my full reproductive system and asshole. Sentient and in control of their functionality. I will even allow you to share my senses. But you must submit fully. My word will be absolute. You bend to my will, and only think inline with my thoughts unless I ask you otherwise. You will forfeit all concept of individual self, and just become my parts. You will act as an extension of myself, and only as that. How does that sound?" Offered the Goddesss.
The price was massive. But so what, you were expecting her to just make you the part without anything else. Now you were even allowed access to a full range of sensory inputs in addition to rarely voicing an opinion. This was already took gold of an offer to pass up. "I accept. Please let me become your parts."
