Dive! Dive! Dive!

The tip of the toy disappeared into the gaping hollow of Michelle's held open ass, and she cursed silently for a moment at the relaxed state of her body, knowing she would only be able to feel a little of what was going on.

There was only slight pressure in her as Kelly's first toy reached the bend in her colon. As soon as she felt a little pushback, Kelly slowed down and began to press the pencil shaped head of a twelve inch long dildo around the corner.

Michelle knew this first bend was usually the easy part, at least with a toy this small. Though it got her wondering how something wider and stiffer than the soft toy would do it. That's what the anal training was for, though. She needed to slowly work up through consistent use and straighten that bend as much as possible. Through her studying the topic she knew that with consistent insertion around the bend, the body would slowly change to make it easier.

There pressure came and went in light waves as Kelly began to pump the dildo in and out, and it would keep popping around the first bend within Michelle. Eventually she bottomed it out completely, and Michelle saw the numbers through the monitor. 1.5"x12"-S.

"Mmmm." Michelle moaned a little as Kelly let it sit inside her. She may not feel much physically, but again her mind was pushing to fill in the gaps. "What does S mean?"

"Soft." Kelly responded. "We start with softer toys as we train your bends, and work up in hardness as we work our way deeper. It helps the body adjust better that way."

Michelle felt the release of pressure in her as the toy slid out effortlessly a couple minutes later.

"How long is the next one?" She asked.

"We'll be moving up to sixteen inches, next." Kelly responded happily, "we will start to work around the bend of your Sigmoid colon. Depending on how deep you are, this should get you just past it, but also may reach your first colic flexure if you're on the shorter end."

Michelle had read up enough to know about the sigmoid colon, but the next point was a foreign term to her. She just decided it meant there was a third bend deeper within her.

The tip of the new toy entered and moved smoothly up and through her first bend, and Michelle could see the extra couple inches left to go as Kelly worked. She was surprised that, as Kelly began to probe deeper, it was as though she could actually feel a little more of the pressure. She guessed there was only so much of that the tea could relax away for her.

Kelly slowly pushed and turned the probe as it met that internal second bend and Michelle let out a light gasp when it finally popped around that corner and she felt it creep further within her. She once again began her pumping motion, slowly popping it back and forth around the bend.

Michelle felt her insides loosen with each successive thrust and soon the toy moved effortlessly in and around the sigmoid and began delving deeper. There was a warm feeling in her stomach that followed the movement and continued to keep her horny as she imagined. As she began to squirm ever so slightly she finally noticed a small button near the fingers of her right hand. "Bip." With a small bit of feedback she noticed the monitor now changed to a clear overhead view of her stomach.

She admired her own toned shaped for a minute as she watched Kelly's hands work at the bottom of the screen. Pumping the toy in and out. She examined her stomach, imagining seeing a bulge as the tip moved further inside her, but knowing this toy was probably a little too skinny to show up.

Michelle had begun slightly moaning at the thought, and lost in her daydreaming she hadn't even noticed several minutes go by and Kelly had switched to the next size up. That is, until it reached her left colic flexure. There was a noticeable amount of pressure, and Kelly slowed, to begin gently working and twisting the invader deeper and deeper, bit by bit.

There was a combination of intense pressure and orgasmic release as Michelle felt the toy finally pop around the corner and into her transverse colon. Then it was gone as Kelly slowly pulled it back out for a moment, before the pressure returned.

Michelle's mind and body began to go a little crazy as it pumped deep within her. She hit the button once more to change the view back, to better see this source of pleasure better pumped in and out amidst a steady stream of fluid from her pussy at the top of the screen.

"Ooouuhhh!" Michelle moaned out quickly as Kelly finally bottomed out and held. Because of her relaxation it wasn't nearly as much as she'd hoped, but Michelle smiled as her first ever anal orgasm hit her. Again cursing that she couldn't feel it more. She looked back to the monitor reading the side of the toy 1.5"x20"-S

"One more for today." Kelly spoke up, but Michelle was too entranced, watching twenty inches of shiny black rubber gently slide out of her; a few small aftershocks of pleasure, like a small breeze washing over her as she did.
