"Bruno, you're really an expert masseusse," you mutter in ectstasy.
"Masseur. Masseusse is female, masseur is male. Thanks, but I'm only doing this to work my way through college. My real major is Cybernetics. You know I'm recruiting volunteers to help me with my thesis...think you might be interested?"
"Yeah, sure. Uh, what's involved?" you ask realizing you just volunteered for the something.
"I'll show ya," Bruno says taking one hand off your back and reaching into his gym bag. You expect him to show you a paper or brochure, but instead you feel something cold and metal touch the base of your neck. Then you see fireworks, and feel a burning pain before you black out.
When you regain consciousness you're feeling disconnected. Your eyes focus and you realize that Bruno is holding your head in his lap. His red speedo can't conceal Bruno's 8 inch boner oozing precum through the fabric just inches from your eye.
"Ah, you're awake!" Bruno says. He lifts you up in his hand. Your mind screams, "WHERE IS MY BODY?" as Bruno recites a line from Shakespeare, "Alas poor Yorick, I knew him." Then he tosses your head into a hamper with your missing body parts.
"I know. I can hear your mind shouting to Batman, "Holy, Mr. PotatoHead!" and you're right. I have disassembled you. You see I massaged nanobots into your body. They instantly spread themselves throughout your body, and integrated themselves with your biology. Then my pulser signaled them to implement their modification of your body. Oh, and its not done yet. You see when the nanobots are done, your body parts will be identical and interchangeable with my other volunteers. Hehe. I tried using the nanobots on raw materials, and even on electronic components, but the results were abysmal. You see I used nanobots that had been developed for medicinal use, and they seem to require a human host to perform my programming. Well, I'd better get you back to my lab," Bruno says tossing towels over your head, torso, legs and arms. You feel him hefting you and the hamper in his powerful arms. And your head begins to rotate involuntarily as he walks down the long hallway toward his lab.
