Celestia ignored the chaffing feeling of the straps on the table. Ordinarily quite happy to have Twilight tie her down spread-eagled on a table, today she was using all of her legendary patience to endure the moment. Also the promise that the straps and table would be used for a very different purpose. And there would be a nurse outfit involved.

She had been through worse, it was true, even at the hooves of past lovers. Being turned into pure chocolate stood out in her memory for a moment. Also going skinny dipping in an enormous jar of jello. Twilight gathered an especially large thermometer and began applying a cool jell to her wrists, stomach and hooves. The look of excitement on her face was all Celestia needed to remind herself exactly why she was doing this. Also, the invaluable chance to study alicorn anatomy in comparison to the average pony's medical data! Celestia had questioned why Twilight did not simply test upon her self, and was met with a curt 'observational bias'. Celestia's face contorted as icy clouds descended upon her more sensitive regions, and glared at the offending suction cups lowered onto them. The sun diarch arched her back and stifled a moan as the buttons stuck fast against her chest. She noticed Twilight taking a hurried note.

"Writing observations about my nervous responses?" She probed. Twilight's face lit up in a blush, and she stammered a "no" before going back to her observational booklet.

"Heart rate and blood pressure monitoring: check."

"Beginning internal body temperature measurement." Twilight grabbed a smaller thermometer in her magic and levitated it into Celestia's mouth.

"Try not to speak, Tia."

"Wait, Twilight what about the other--mmph." Celestia sulked as the delicate measuring instrument (electronic, not mercury based) entered her mouth.

"First set of data, check! Gathering secondary source of data." Twilight once again produced the larger thermometer, approaching Celestia's other available orifice. Celestia's eyes widened in horror. To her slight shame, she may have even struggled to break free of the magic nullifying table and its oddly strong straps.

"Mmphmmph--!"

Celestia sighed into her thermometer, and only to be interrupted by a nuzzle.

"Thank you for doing this for me, Tia."

Perhaps the day was not going to be so long after all.
