You decide to take the dress, afraid the pen might involve some... violence. Besides, its just a dumb dress, no shame in wearing it. That is until she brings in a scientist.
"This scientist will be merging with you as part of some experiment, i don't know..."
The scientist corrects her, "Actually, Ms. Kelly, I'm afraid you are mistaken. You see, it is YOU who will be merging with him."
Kelly's protests were meaningless to the scientist, who held the two of you down on each other until your dick was basically rammed against her ass. The two of you become one, and are subjected to highly sexual tests, oh, why couldn't she have just have read through that contract?!
