Beth felt frisky. She was an early riser, so it was no wonder she felt active just after she awoke, but her sexual drive was not usually that strong. Only after sitting up in her bed she realized the probable cause - she slept with her newfound plug in her anus.
She blushed - even though noone knew, and noone WILL knew, she still felt dirty about using a lewd toy like this. It still felt comfy in her tight behind, only giving a gentle pressure as she sat on her bed, despite being inside her for a whole night.
"Enough about... this. I need to get ready, they might come any moment," she thought, referring to her two gang members, Gom and Jalil. First, she pulled on her plug, surprising herself how easy and painless its removal was. The plug was whistle clean, warm to the touch, and somehow... bigger than she remembered? The stem, the part that connects the two bigger parts of the device, certainly seemed wider, about 1,5 cm (0,6 in) wide - half a cm wider than she remembered, and even the outer ruby part seemed larger. She smiled to herself - it was obviously impossible that the plug grew overnight, but it would be amazing if she could somehow fatten it, getting a really expensive gem as a result.
After washing the jewel, she took a shower herself. She liked cold showers, they made her feel more alive somehow. When she arrived to her private parts, she experimentally touched her anus with her index finger, and surprised herself when she easily penetrated the hole two knuckles deep. Maybe the guys who wanted to try anal with her had the right idea after all, seeing how little it took to penetrate herself.
After drying herself, she dressed in her standard attire - underwear (a pair of white panties, she did not need a bra for her tiny boobs), a white cotton blouse, and leather pants and jacket. By the time they arrived, she was already done with the packing, including the plug safely hidden in her bag.
Their group consisted three people: first Jalil, the oldest guy in the group, who was a trained assassin, had excellent skills with the knife, and generally made the shots; he was short, lithe, and had dark hair, complexion, and humor. The second was Gom, a big blonde hunk, who had endless energy, and was usually in good spirits. He fought with a freakishly big battle axe. The third one was Beth herself, a spellslinger, or as she liked to call herself, a "battle mage". The two guys usually just called her the "Ice Queen", partly because she used ice for most of her magics, and party because her demeanor.
Beth saddled up, and rode out the meet them, preferring if them and her father did not meet in person - nothing good would come out of it. After offering mutual greetings, they set out for their journey.
"I heard you had a good catch yesterday," Jalil started a new topic. "Some Stretchington noble sent a present to a rich relative in Multipedete, but the caravan was robbed. I would bet ten gold coins that it was you, it was within a stone's throw distance from your tower. Was the loot plentiful?"
"Where do you get your information so fast?" Beth asked back. "And yes, it was me, and yes, they had a lot of gold". She decided not to mention about the butt plug, not wanting to get teased about it.
"I have my sources. Be careful with caravans like those, the people of Stretchington and Multipedete do not really like each other, you might spring a trap next time that was not even aimed at you."
"That is all good and well," interrupted Gom, "but can we talk about the upcoming mission? That seems much more important to me."
"It is about three days distance if we don't rush our horses, and we need to keep them in top shape," Jalil explained. "Lamias move much faster than us on foot in the desert."
"Sure thing, but what is the plan?"
"The plan is to ambush them while their guards are away, free the slaves, get their money, then get out. It is so freakin' simple that even you can understand it, Gom."
Beth smiled to herself while listening to their banter. These two were already teammates when they met her about two years ago, banding together as a necessity, partly because they both had fairly big bounties on their heads in multiple cities, and party because these parts of the Judgement just lacked able fighters. First they were only after her body, but after getting to know her, they recognized her spellslinging abilities and her spirit of adventure.
Beth herself was really happy that these two guys turned up; she lived a sheltered live, tutored by her father, practicing spellcasting every day. Her biggest source of excitement were the occasional customers in her father's shop, but when any kind of creature came in to buy something who was considered a freak by Robert's, her father's standards, she was forbidden to meet with it. Then these two came.
They were deemed acceptable even by Robert, who did not know their pasts at that time, and thus, after a while, Beth was allowed to go on a few journeys with them. She lost her virginity to Gom, his huge muscles and broad shoulders were just too hard to resist. She also had sex with Jalil a few months later, his rugged look easy on her eyes. And even tough those sensual relations did not last long, their friendship did, and she became a permanent part of their small team.
The route to the naga village was mostly uneventful, except for a few things. Beth was permanently horny. Even though no lewd thing has happened, even though nothing should have reminded her of sex, she was still in heat. She tried to hide it from her teammates, the focus on this mission was far more important than a quickie or two, and she thought it was just unprofessional to have sex on the job anyway.
The other thing was her boobs. They were itchy, sensitive, and somehow... Swollen. She realized on her second day that they were actually bouncing a bit as they rode. When she examined them at night, she measured them around a B cup. She had no idea why those lewd things were happening to her, but she figured she would have enough time to examine herself more in detail when they were done with the mission. At least the increase in her bust size was fairly hidden under her clothes, so she was able to avoid unwanted questions about it.
The mission itself at least went smoothly, although Beth had little to do with it. The entire naga village turned out to be just a small slave camp, with only a few naga slavers to occupy it, besides the thralls of course. The only thing Beth had to do was to freeze a specific naga who handled a transmitting device before the creature had the opportunity to call for help. She almost messed up, fumbling the freezing spell the first time, she was too aroused to concentrate, but the second time she succeeded, barely in time.
"What's up with you?" Gom asked after they knocked the last naga out cold, then freed the slaves. "You don't seem like your usual self. You messed up your freezing spell once, and I never seen you mess up before."
"I don't know, I'm just... out of it right now. I can't really explain. Hey, what are you doing?!"
