"Now this will be very simple, and we can prevent all this." Narytiss explained. "Simply go to my ship, and..."
"I don't think so..." Lindsey said. Lindsey was able to read all the thoughts of Narytiss at this point. "I would really like to get bigger."
"Wait, what?" Narytiss said, confused.
"Bigger than any human ever? And still be perfectly healthy? That really isn't an offer I can pass up."
"You don't understand, it will force me to grow too, I'll never be able to return to my planet...I'll fuse with you and..."
"And keep making me bigger, right?" Lindsey said. She thought she knew everything Narytiss knew at this point, but both creatures could still hide thoughts from the other.
"But..."
"Stop it. I can easily silence you. I can easily force you to remain inside me. I can't pass this up...I'm really sorry...but this is a dream come true." Lindsey said, with a smile.
Lindsey had shut her mind off from listening to anything Narytiss would say. Narytiss had become a prisoner within Lindsey's body, unable to escape, but required Lindsey in order to survive. The waste and negative aspects that were produce in Lindsey's body flowed into Narytiss as the days passed. She felt nourished, she felt amazing, she felt like this was heaven Her body formed into a perfect female form, and slowly enlarged. But these pleasures were all physical, and Narytiss longed for her homeworld...longed for her own family and friends. It was paradise, in a cage.
Lindsey, on the other hand, was still around her family and friends, but received the same nourishment from Narytiss. She felt as amazing as the alien inside her, but was still free. Narytiss could only live through Lindsey's eyes, viewing what Lindsey could see. On a daily basis, Lindsey would examine her body, which grew anywhere from half an inch in height, to 2 inches. Her breasts burlged forward, her hips flared outward, her butt was full and perky, and growing more and more perfect.
