The black slime possesses the younger sister

While the older brother of the house was in the laundry room, looking for a pair of his mother's used pantyhose, the younger sister of the house was fast asleep and completely ****.

Again, the black slime stealthily crawled throughout the house before quickly finding its true target: the younger sister. Although it was designed primarily for "female pleasure," the nanobots on this day would not be here to pleasure the girl.

Instead, the mass of slime went directly for her nostrils and mouth, completely covering both of them for mere fractions of a second before extruding themselves out into her body, thus distributing the nanobots into her bloodstream, and eventually, her brain.

There was a very brief moment of struggle, but not before the nanobots had started the process of rewriting the girl's neural patterns.

Pretty soon the nanobots had taken control of her Central Nervous System, brain, etc - her entire body was at the mercy of the nanobots.

But of course, this was still the first time the nanobots had connected with a human life form before.

The possession part was easy enough, but the nanobots wanted to do more things than just possess somebody.

They also wanted to know more about how other humans work, specifically...

Males.
