To study humans by living among them

"Hello there human" she greets you. "I am Pink Diamond here to live among you and your kind." You decide to play along and just go with it. " I would be honored my diamond" you say crossing your arms and bending your wrist to make a diamond. "Oh my." She smiles "I didn't know you little creatures knew about this" As realization hit you forgot humanity does not know about the Gem race. So you try to play it off saying you learned it from other gems you saw. She nods in understanding. "So would you like me to show you around the house?" After a quick explanation of what a house was she came inside to see the big isolated house to be shown what she will be calling home.

You try to lead her around but she begins exploring on her own going in whatever direction seem the most interesting making you stare hardly ever taking your eyes off to both keep track of her and admire her at every angle. She was like a big, punk, energetic, curious, kid exploring her new home. She begins to ask all sorts of questions related to what she was interacting with at the time such as what was the flat black box in the living room, where did the water in the sink come from and go to. She was adorable and naive it seemed so as she went about her process.

While doing this you feel an urge to take as soon as possible but this innocent beauty you so long craved but don't want to ruin the IRL experience you figured if she is still oblivious to the concept of sexual actions as a being in race that does not need to partake in such actions you could easily get away with a with a wandering stare, a lingering hand, or even a few accidents from a "clumsy human" and end up in a few situations.
