She shows you.

Amy opens up her plastic ball as she talks. "That was the strangest order form I have ever used! It was like I could type whatever I wanted! So...when it asked for tit size I put 'the biggest I have ever seen' and for the dick I put 'as big as it needs to be to make me happy'. Then it's how it looks here." She holds up her assembled piece for your inspection.
"Haha wow, look at that! Maybe we can swap sometimes!" You see hers is similar in look to yours. It has a tail and horns, but it is blue and has more accentuated curves. A big butt, wipe hips and breasts that are proportionally larger than the largest implants you have ever seen stand out the most. Also, she is wearing sort of a full body harness with holes that let her tits, ass and cock hang out.
"Why don't we talk more about it at my place? The apartment building is just a few blocks away." She puts her doll away as she starts off without waiting for a response.
"Sure, I don't see why not!" Well, at least you don't feel so bad if it happens that you got scammed for a few thousand as long as you weren't the only one to fall for it. You arrive at her place without being further bothered by any more strange feelings.
