"Hello, I'm Dr. Matthews," said Brett extending his hand.
"Hi, Steve Wheeler," the young tanned blond said shaking his hand.
"So you want to volunteer to be our jeep?"
"Yes, I do want to tryout the Jeep interface."
"Well, you look rugged enough - I mean up to the challenge," said Matthews. Why don't I give you a quick physical and then we can get started. Please take off you clothes, Steve."
Steve pulled off his shirt and went to undo his jeans, when he paused and blushed, "Dang, Doc, I went commando today."
"Nothing I haven't seen before, I need to give you a thorough exam."
Ten minutes later while Brett was winding up the exam, a grad student came in carrying a full syringe and clipboard.
"You're late," commented Matthews, "I'm about to give the subject his prostate exam. Bend over and grip your ankles," he told Steve.
As his gloved hand worked it's way into Steve's lubed ass, the alarm sounded on the grad student's watch. He took the syringe and swiftly jabbed Steve's bare butt cheek.
"Subject injected with formula 13 at precisely, 5 o'clock," he announced jotting it down on his note book. "I set my alarm for 4:59," he added.
Brett felt Steve's butt cheeks clench tight. He glared up at the grad student, "You do know this is room 13, and you were supposed to bring formula 4 into this room. Now help me pull my hand out. I'm stuck."
"Oh, oh, whoa!" shouted Steve standing up abruptly as the nanobots went to work inside his body.
