Different people will have different preferences and different desire even if they all are into cloning.
For me, since I am a leg and feet guy, one of my fantasy is about my VP at work, because she is super hot. The below is my fantasy about her:
She creates a video of her providing business and inspirational advice. In that video,
She enters a still camera from left side professionally dressed wearing short blue mini skirt exposing feet to top of knee. She sat on the sofa and gave one third of her speech. Then another one of her same dressed entered the same screen and sat on left side of her. But instead of putting her leg on the floor, she wanted more comfort and put her leg on top of the first one's thigh, just like in the picture below. And continued the speech until two third. Then the last identical copy of her entered sat on the right side and also kept her legs on top of thigh of the first one sharing the same spot with the second one, and finished the remaining speech. So at that point, two of her put her legs from opposite side on top of another one of her thigh. The speech is about comfort, and that is what all of her is demonstrating.
I always hoped there will be a bed or sofa advertisement showing it can accommodate multiples of one girl comfortably.
Notice, I don't straight jump to sex, because I want to keep the suspense high. I also love conflicts as oppose to one hive brain controlling multiple bodies.
