Near a swimming pool...

Easily bypassing all the junk and detection systems around the planet, the pod flew down to one of the continents and landed in an area that it deemed suitable to hid itself. It had detected life-forms that lived near its hiding spot, and the large pool of liquid would be a great camouflage for the liquid being within it.

Slowly down, it sunk silently and unseen down the dark waters, waiting for one of those beings to move close enough. Unfortunately, the system that controlled the craft did not understand the meaning of night and day, so it wasn't until noon-ish the next day before someone went near the pool.

Amanda Jules checked the backyard pool for any problems. The children were going to arrive for their summer noon swim soon, and even her own twins were getting impatient from being inside the house all day. She pushed away some of her brown hair from her eyes as she placed her hand in the water. Satisfied that it was clear and not filled with any muck, she decided it was alright for the children to swim in and went back inside.

What Amanda didn't know was that the pod had detected her started the sequence that would release the last of the N into the pool. The ship's computer took stock of what the pool was composed of, and knew that the N could easily survive in it. It slowly released all the locks on it, and waiting for another another suitable host to go near the water.

It didn't take long.

Amanda soon returned with her 18 years old twins, Tammy and Jenny. Both had their mother's brown hair matched with a pair of gray eyes. While their bodies were under-developed like every child, the beginning of female curves were starting to show. Tammy had on a blue swimsuit while Jenny had a red one, distinguishing who's who.

The pair quickly jumped into the pool, unaware that there was now a space invader luring in the pool. The twins splashed a bit in the shallow end while the N slid through the water, its instincts telling it that there's an uninhibited host near that side of the water.

A sudden doorbell distracted Amanda as she went to open the side gates for other children. That was why she missed seeing Jenny shriek as the N slid under her foot and caused her to slip backwards into the water, submerging her and giving the N a chance to **** itself around the young girl's body and into her mouth.

Amanda quickly turned around in time to see Jenny sink into the water and Tammy laughing as though it was the funniest thing she ever saw. At first, Amanda was worried as Jenny didn't immediately resurface, but then the red twin burst out of the water coughing and sputtering (presumably to spit out any water she drunk) before shaking her head as though to clear it from all the water. Sighing, she hoped the other children won't get too rough today.

For Jenny, she couldn't shake the feeling that something was different. She remembers slipping on something, and drinking some of the water. There was this slightly burning sensation from her chest as something flashed by her young mind. As she got back above the water, she had a slight headache, but quickly shook it off and continued playing, greeting her friends as the N started to get used to its new body and mind.
