Ok last bits of advice: “Oh, I’m sooooo scared!..." Seemed a it out of character for Spy. Generally, try to avoid repeating yourself and pointing out the obvious. Let the audience think for themselves and make connections. Also the dialogue got a bit tedious. If the characters are saying the same thing over and over again ("The machine is great try it!" "No I prefer flesh"), either get it over with or summarize it ("They went on like this until finally...") Show, don't tell. Instead of saying "Gee engie sure loves machines", trust your description of him to say that for you. I did enjoy the part where Engie called the Machine Clarice without missing a beat. Looking forward to the porn, and this fic is quite nice.
