extended metaphor

RealDoll begs to differ.

Although I do agree that the tense of the last line is a bit off.

I read this as - N gets a new book from Amazon, and it's like getting a sex doll - his to violate, open, penetrate.
And both show signs of his invasion.

After you commented I tried to reread it unmetaphorically. But it still works as an extended metaphor, doesn't it? N gets a sex doll from Amazon, and it's like violating, opening and penetrating, a new book. And both show signs of his invasion.

It's because Amazon, for me, is only about books.
