Author's Notes
This is a nineteenth and final part to the series. Although it is self-contained from a story perspective, I would recommend you read the earlier chapters as there will be references which make more sense if you have read the earlier parts. Please note, this is a mixed genre chapter with a mix of anal, lesbian and BDSM. Hopefully there is something for everyone, but I thought it was worth pointing out just in case.

Alone again, in the privacy of her mistress' en suite bathroom, Kirsten found herself gravitating towards the toilet once more. It wasn't so much that she needed to go--Kirsten had spent plenty of time doing just that, as she relieved herself of her enema--yet still she felt she had better try just in case, especially if her next step was to be getting filled once more.
It was as she sat there, that Kirsten started to ponder about what she had been told, and what it might just mean. It wasn't so much what her mistress had said about fucking the young blonde's ass. That, much as it thrilled and scared Kirsten in equal measure, was old news. What now occupied Kirsten's mind was the idea that she might get lucky, and the suggestion that there might just be a chance of having two for the price of one.
What exactly did Claudia have in mind?
Would they both be fucking her ass?
Would it be one after the other?
Would it be both together, stretching her even wider?
All the time, as she mulled over the various connotations of that throwaway suggestion, Kirsten tossed the plug over and over in her hand. It was metal, stainless steel to be more precise, but it was so different to the one she had worn on that first meeting with Sophie.
For one, it was big, ever so big, with a shape more like a cylindrical torpedo than the traditional teardrop bulb. Kirsten tried her best to estimate its size using the length of her finger as a guide. It was no exact science, but she came up with an insertable length of about four inches and a girth of... Kirsten gasped. No... no... she must have been wrong. She measured again and came back to the same estimate. The girth wasn't so far off five inches, maybe a little less, but really not that much. Then there was the weight. Kirsten was never a good judge of weight, but it must have been a couple of hundred grams to say the least.
If that wasn't enough, something else grabbed Kirsten's attention, something which literally confused the young blonde, and that was the base of the plug. As expected, it flared out, with a narrow stem linking base to bulb. The difference though came in appearance. Where the one she had used before was jewelled, even to the point of being pretty, this one was rather plain in comparison. Yes, there was a touch of decoration in the form of a couple of rubber rings going around the edge of the base, but otherwise it was just solid metal.
It seemed this plug was all about function rather than form, more to be used than to be seen. When it came to being used, that was the other thing which confused Kirsten. In the flat end of the base, there were two holes, one dead centre and another over towards the edge. Kirsten was still pondering their meaning, when a call from downstairs broke her out of her contemplative state.
"Lunch is ready, Kirsten," Claudia called out.
Kirsten jumped up off the toilet. She hadn't needed to go, which was a relief, but that sense of relief was now overtaken by a more pressing need; a pressing need to get a move on and get back downstairs. Suddenly there was haste in her actions. Rummaging in the bathroom cabinet, Kirsten found just what she needed. The only question now, was where and how to get on with the job in hand.
The answer to that question came back in the bedroom. Kirsten carefully placed first the plug, then a large pump bottle of lube and finally a handful of tissues out atop the duvet of her mistress' bed, then settled herself down close by. She took to lying on her side, leaning forward ever so slightly with her uppermost leg raised as far as she could towards her stomach. She reached back. It was a stretch, but it would have to do.
What followed was a bit of a display of contortionism as the young blonde lubed herself up. It was a little to start with followed by a single finger up against her rosebud. She rimmed her opening. She pressed a bit firmer, willing her finger to sink inside. All the time, Kirsten was met with resistance, yet never did she give up. Kirsten went back to the bottle, applied just a little more lube to the tip of her finger, then reached back for her ass once more. She repeated the same two or three times. Finally, with a stifled gasp from the young blonde, her tightness started to wane, and she dipped that finger up inside.
It was a strange sensation. It always had been, a bit like she was pooing but all in reverse. It was strange, but somehow it was pleasureful, and Kirsten couldn't help herself but withdraw her finger, add another dash of lube, and try again... and again... and again... and the more she tried, the more she relaxed, and the more she relaxed, the more she enjoyed. It was a far cry from anything she had done before, but once again, just like earlier in the day, there was something satisfying about that feeling of a finger up her ass.
A finger was one thing, but that plug was something else, and didn't Kirsten know it. Before long, one finger, along with even more lube, had become two, squeezed up inside her tight little ass. She probed deeper. She eased the two digits apart within her opening. All the time the young blonde tried to stretch herself out, making herself feel ready for what she knew was to follow. She thought about a third finger, but the awkwardness of her position was just too much to get the angle, and Kirsten resigned herself to the obvious.
It was now or never.
Kirsten reached first for the lube, applying a large dollop of slickness to her fingers, then easing the same into her opening. The plug was next, getting a similar treatment with a copious amount of gel applied across its surface. Reaching back, she positioned the tip against her rosebud, shivering slightly at the coldness of the steel.
Kirsten held her breath.
Kirsten bit her lip as she started to work the plug.
She could feel the stretch down below as the torpedo-like bulb widened out. At first it felt fine, that feeling of fullness against her opening, but before long the stretch took on another dimension, a more uncomfortable dimension. Whatever she tried, it was to no avail. Stretch she might have done, but take this monster wasn't quite on the cards, at least not yet. Kirsten though wasn't about to give up.
A little more lube...
A little more with those two fingers, finally straining to add the third if only to mimic the girth of that mighty toy...
