Callie lay, facing the wall in the left lateral position, her right leg pulled up towards her chest. The lightweight blanket was just covering her hips leaving her bottom exposed. Keiran moved behind her and Callie heard the sound of latex stretching and releasing as he pulled on a new pair of gloves.

"Little bit cold again now Callie" he said, and Callie shivered as she felt him part her bottom cheeks and spread the cold lubricant around her anus liberally before pushing his finger through her tight sphincter. Next he thoroughly lubricated the long orange colon tube and began feeding it slowly inside her. It was an odd sensation and Callie couldn't help involuntarily clenching her bottom as the tubing was pushed inside.

The tube slid in easily at first. It was cool, slippery and kind of ticklish but as the tube reached her sigmoid colon it became uncomfortable and Callie moaned softly as she began to experience a kind of crampy ache deep inside her. The doctor pulled the tubing back and slowly continued to thread the equipment inside her again, gently rubbing her bottom to sooth her. Callie began to find it very arousing!

"Well done Callie, we're almost fully in now, just relax. I'm going to introduce the water now"

The enema progressed very comfortably and as the water flowed inside her, Callie began to relax. There were no more cramps, despite the fact that, being three litres, this was a higher volume than she had previously taken. As the water continued to fill her, Callie could feel her stomach swelling.

When half of the bag had been administered, Keiran stopped the flow and helped Callie roll onto her back, pushing the blanket to one side before restarting the flow again.

Keiran lifted the hem of Callie's gown, exposing her swollen stomach. It was odd but the change of position made Callie feel suddenly quite embarrassed. She, closed her legs, aware that now, he could see her vulva.

Callie didn't know why she suddenly felt such shame, especially since Keiran had obviously needed to examine her internally before, when the thermometer had been lost, although her exposure had been the least of her worries at that time.

"Just let your legs fall open Callie"

Keiran requested, as though he was fully aware of her embarrassment and felt it necessary to ramp up her humiliation. Logically, Callie understood it was only because Keiran needed better access as, once she allowed her legs to open, he began to remove the tubing whilst at the same time rubbing her stomach in a bid to allow the water to move around inside her.

Eventually Callie was helped to the toilet one last time where she expelled the enema. At the start of the treatment, Callie had feared the enemas but now she felt they would be something that would be staying in her life for a very long time. Not only had Callie found the process to be very stimulating and erotic, she also felt clean and light and energised. No, Callie certainly would not be complaining if, in the future, the doctor ever wanted her to have more.
