Betty left to go get a chair. While she was gone Jen lay down on her own bed and watched Mina as she twisted and writhed in her cage. It was surreal. Jen had never really seen another girl get off before. Sure she had masturbated herself and even considered what sex would be like when she got a boyfriend, but the thought of another woman hadn't crossed her mind. Now as she watched the strange red haired girl roll onto her belly so she could grind herself into the cushion and push the vibrator deeper she found her own hips shifting as well. She quickly forced herself to lie still as Betty returned pushing an office chair with a cardboard box on it. She wheeled it in between the two girl's cages, removed the box, and sat on it backwards while giving Mina a look that was a mixture of awe and disgust.
You know," she said after a moment. "I was going to grab the chair from the storeroom next door, but it seems like someone has been using it recently for unauthorized activities and not properly cleaning it when they were done. I don't think it's possible to sanitize it anymore. I might have to throw it out."
Jen could swear that this revelation just made Mina more frantic. Her movements picked up speed and the noises she was making around her gag got louder. Betty noticed this as well. She reached down into the box and pulled out a long red object which she held up for both the girls to see. It was a dildo, Jen realized, but not like any of the ones she had seen when she and her friends had gone into the local sex shop on a dare. This one was oddly pointed and had a weird double bulge near its base. Jen's eyes widened in horror as she realized what kind of penis it was modeled after.
"These, however," she continued, "I was able to sanitize, and I must say I am very disappointed in you. Did no one ever teach you that you need to clean your toys between uses? I'm surprised you didn't get an infection considering the state of some of these. Clearly while Ms. Lockehart is teaching you obedience and responsibility I will have to take it upon myself to teach you proper hygiene."
Her words seemed to make Mina truly desperate. She flopped over onto her back again and began clawing at the toy embedded in her snatch. Her actions were in vain, as Jen well knew. The gloves they were wearing had thick leather pads on the palms and the first knuckle of each finger. The way they held the hand meant that you couldn't curl your fingers inward to grasp objects. You might be able to hook things with your finger tips, but properly holding onto things was impossible. The poor girl began whining even louder and pushed her hips up to the bars while spreading her legs as wide as they would go.
"What's that girl?" Betty asked with obvious amusement, "Did Timmy fall in the well?"
Mina's whines pitched up again and she raised herself even higher. She was shaking now and clearly in some form of distress. Betty turned her chair to Jen instead.
"What do you think Jen," she asked with a mischievous twinkle in her eye, "Should I help the poor girl out or let her suffer for her crimes. You know she was pretty much using you to get off without you knowing right? Borderline sexual assault in my book."
Jen looked at Betty, then at Mina, then back at Betty again. She didn't know what to do. She was forbidden from communicating in any way a human might. Dog language only until her training was complete. She thought of Betty's Lassie joke from a moment ago and realized just how apt it was in their current situation. She let out a pitiful whine of her own that was almost drowned out by the increasingly louder ones Mina was making. Betty considered her with a calculating look, then leaned in close to the bars.
"I know you're not allowed to talk," she said quietly, "I helped Ms. Lockehart devise the rules for your training. I was only doing it as a medical advisor, obviously, my first responsibility is health and well-being. This means I happen to know that there is a special rule where I am concerned. I bet Ms. Lockehart completely forgot to mention it to you, she always forgets the important parts, but you are free to talk to me since I am a medical professional. Technically this only applies while you are in my exam room and it doesn't actually pertain to our current situation, but I think that a nod or a shake could be allowable. Just this once."
She sat back up in her chair and waited to see how Jen would respond. Jen contemplated what she had just been told. She wanted to be a good girl, she had been training as one all week after all. She didn't think Betty would lie to her about the rules either. She looked back over at Mina. There were tears streaming from the redhead's eyes. Her whines had died down to a pathetic whimper. She felt... something... for the poor girl, though she couldn't put her her paw on it. Was it pity? Jealousy? Her hips shifted again and she felt a bit of heat rise in her cheeks. No, it couldn't be *that*, don't be ridiculous. She gazed at the other girl for a few more moments, then looked up at Betty and nodded once. Betty smiled and turned back to Mina's cage.
"Looks like today is your lucky day! Jen thinks you deserve a bit of help. Don't count on this happening again any time soon though, this is meant to be a punishment for neglecting your job."
Mina whined in relief as Betty climbed off her chair and crouched down outside the bars. She reached into the pocket of her white coat and produced a pair of latex gloves which she pulled on with a snap. Then she reached down and gripped the end of the vibrator sticking out of Mina's wet cunt. She paused for a moment, looking down at the quivering girl, then pulled the vibrator out almost its full length and plunged it back in again. The effect was immediate. Mina screamed in pleasure, muffled still by the ball gag held between her teeth. She pushed herself up higher and rocked to meet every thrust. Betty was merciless and kept up her quick, deep strokes even after Mina's legs gave out and she collapsed onto the bed again. She didn't stop until it was clear that the girl had passed out from exhaustion. She carefully reached through the bars and checked her vitals, then rolled her onto her side and pulled the vibrator free. She reached into the box that contained the contraband that had been retrieved from Mina's locker and pulled out a pack of sanitary wipes which she used to clean the toy before dropping it in with the others. Her task complete, she sat down on the chair again and turned it back to Jen.
Jen wasn't paying attention to her, she was still staring at the unconscious girl lying in the cage opposite hers. She didn't know how to react to what she had just witnessed. The sight of Mina in the throws of ecstasy had burned itself into her mind, replaying itself over and over again. She felt suddenly uncomfortable for the first time in days. She had grown used to the restrictions of the pads and gloves, they didn't trouble her in the slightest, but now a new feeling of restlessness had taken over. She shifted her position, flipping her hindquarters from one side to the other. As she did she rubbed her thighs together. They felt weird, the skin seemed to slide differently, and there was an odd warmth coming from her crotch. She wiggled her hips so her thighs rubbed again... and kept wiggling. It felt good. She was snapped out of her trance by a polite cough from Betty.
"What's the matter Jen?" she asked with a sly smile, "You're looking a little antsy. Don't tell me you have fleas?"
Jen let out a frustrated whine, but cut it off just as soon as it escaped her throat. She realized she was still wiggling her hips and forced herself to lie still. She realized what was happening. She had been so focused on being a good dog this past week that a bit of her human thinking had lapsed and it had taken her longer than it should have to recognize the obvious signs of arousal. She tried to hide it from Betty, but she knew by the rising heat in her face that it was no use. Betty, still smiling, removed her gloves and replaced them with a fresh pair before opening the gate and sidling into Jen's cage.
"I'd better check you just in case. If you do have fleas it might spread to the other dogs and I'll have another mess to clean up. Best to nip these things in the bud am I right?"
She knelt down and took Jen's head in her hands, turning it this way and that while running her fingers through her hair on the pretense of looking for fleas. Once she was satisfied that there weren't any on her head she pushed Jen down and began running her hands down her sides.
"You don't really have many places for fleas to hide." she mused, "but it's still good to be thorough."
She pushed Jen's arms up and examined the stubble that had grown back in since Jen hadn't been shaving for the past week. Jen squirmed and suppressed the urge to giggle, Betty's probing fingers tickled a bit. Now she was on her back, Betty running her hands over her chest. Her blush deepened when the woman's thumbs rubbed across her stiff nipples but Betty didn't stop and continued down over her stomach. She reached the girl's hips and gripped them, twisting so that they were lined up with her shoulders and forcing Jen's knees upward. Then she ran her hands down her thighs until she reached the leather kneepads.
"These haven't been causing you any problems have they?" she asked while she ran her fingers under the edges. "We rarely have problems with ticks in the yards but they aren't unheard of, and just around your pads would be a prime spot for them to hide."
Jen shook her head. She was breathing a little more heavily than she had been a moment ago. Though Betty was giving her a proper exam she also seemed to be deliberately squeezing and massaging as she went. Satisfied that no parasites were sheltering under the leather encasing Jen's knees, Betty continued down her legs to the leather covers on her feet. These she checked just as thoroughly as her knees, even pulling her feet up and inspecting in between her toes.
"I think we should get you in for a trim soon." she said, tapping one of Jen's toenails. "These look like they might be getting a little long. But no sign of hitchhikers here. Just one last place to check."
Jen shivered with anticipation. Betty was doing this on purpose just to get her all worked up. It was a good idea to check for fleas and ticks, she was spending time in places where you might encounter them with none of the usual protection, but it was obvious that Betty had additional motives. She gripped Jen's knees and gently pushed them apart. Jen resisted for a brief moment but gave in without much of a struggle, spreading her legs and exposing her dripping pussy. Betty gave her a smile that was almost predatory. Jen shivered again.
"What do we have here?" Betty asked coyly as she traced one gloved finger along Jen's inner thigh.
Jen whined again as Betty held her hand up and rubbed her finger and thumb together to demonstrate how slick they had become. Betty was clearly just toying with her now and it was driving her crazy. She began wiggling her hips again in a desperate attempt at getting her attention. Betty pretended not to notice, contemplating the slick fluid on her hand instead.
"Oh dear, I'm getting distracted aren't I?" she said in mock exasperation, "I need to finish checking you for fleas!"
She reached down gripped a tuft of Jen's pubes, giving it a gentle tug as she calmly examined the area. She took her time, poking and prodding while making little humming noises to herself. If Jen started wiggling too much she would give her a gentle warning slap on the buttock. Jen couldn't take it much longer. Betty seemed to know all of her weak spots and exactly how to manipulate them to best effect. She caught Betty's eye and gave her the most pitiful pleading look she could muster. Betty gazed down at her for short while, and finally relented.
"Alright," she sighed, "You're parasites free. I guess now you want me to reward you for behaving so well during your exam? You can nod if you want to."
Jen nodded her head vigorously. Betty laughed and stood up, causing Jen to whine louder.
"Stay." Betty said sternly. "I need to grab something so I can reward you properly."
Jen watched nervously as Betty stepped out of the cage and started digging through the box of toys. She remembered how large the vibrator Mina had used was. Jen didn't think she could handle something that size. She was still a virgin. Though her friends joked about sex toys she had never had the courage to actually buy one for herself. Her hymen was already gone from a gymnastics accident a few years ago, her gynecologist had confirmed that for her, but she had never in her life had anything more than a thin speculum inside of her and that wasn't all that comfortable. She knew that in her current state she was entirely at Betty's mercy, and hoped that Betty was the merciful type.
It seemed that Betty wasn't through teasing Jen though. She hummed quietly to herself as she carefully perused the selection of toys. After a few moments searching she held up a thick knobbly dildo and contemplated it. Jen whined in fear at the sight of it, but Betty shook her head and dropped it back in. This was repeated with a spiky vibrator, the dog dildo from earlier, and something that looked like a cross between a banana and a fern leaf. Finally Betty decided that Jen had had enough teasing for one day and pulled out a small pink toy. She carried it into the cage and held it up for Jen to inspect as she knelt down between her legs. It was only about eight inches long and around and inch thick and was covered in little bumps. Jen couldn't take her eyes off it as it waved in front of her face.
"This was the smallest one she had hidden here." Betty explained, "When I gave you your intake exam I noticed that you hadn't seemed to have seen much action down there so I figured that the rest of her toys were probably a little too much. This one should be more than enough for you though. I think you'll enjoy it."
Jen watched nervously as Betty lowered it and began gently rubbing the tip up and down her labia. It felt strange, but not bad. Jen found herself pushing against it as Betty turned it and rubbed it lengthwise against her lips. Her breathing was speeding up again. She kept having to stifle the moans that were building up in her throat. Finally Betty pressed her free hand firmly onto Jen's pubic bone and lined up the tip of the toy with her entrance. Jen held her breath as she felt it slide slowly in. Betty took it slow, pushing the dildo in a few millimeters at time and letting Jen have a moment to get used to it. Eventually it had slid nearly its full length into her and Betty stopped, holding it steady. Jen's breaths were coming in gasps now. Betty held perfectly still for nearly a minute, holding Jen's hips down and the dildo in place. Then without any warning she gave Jen's clit a hard flick with her thumb.
Jen's world exploded in a kaleidoscope of pleasure. She'd had an orgasm before, but the hesitant fingering she had given herself was nothing compared to this. Betty began sliding the dildo in and out, not as fast and hard as she had done with Mina, but a firm steady stroke that kept Jen riding the wave of orgasmic bliss coursing through her. She lost all sense of time as Betty kept the pleasant sensations flowing. Every time it seemed like Jen was coming down from her high she would give her clit a skillful tweak and send her soaring again. When that began to lose its effect she twisted the base of the dildo all the way around and surprised Jen with how strong of a vibrator you could fit in something so small. The whole time Jen never had enough breath to make anything more than a strangled squealing sound. Finally her body could take no more and went limp. Her head fell back onto the soft cushion and her vision went white around the edges. Betty took this as her cue to finish and pulled the vibrating toy free.
Jen just lay there, absolutely stunned. She could feel the blood pounding through her veins but none of it seemed to be reaching her head which felt lighter than air. She shook as her overstimulated nerves fired random aftershocks of pleasure. Her arms were still up above her head and her legs spread as Betty had left them but Jen didn't have the energy to move them beyond a twitch. She watched through a haze as Betty stood up and cleaned off the toy before returning it to the box again. She turned and looked down at Jen, smiling gently.
"Is that better?" she asked, "Did you enjoy yourself?"
Jen wheezed and tried to nod but her muscles wouldn't do anything but twitch randomly.
"I'll take that as a yes then. You look like you need some rest. Take a nap and I'll let Ms. Lockehart know that you need a break this afternoon for medical reasons. I'll come back and check on you at dinner."
With that, Betty secured the cage again, checked that Mina's was properly shut as well, then grabbed the box and pushed her chair out of the kennel. Jen tried to watch her go but she was thoroughly worn out. She closed her eyes for a brief moment and didn't open them again for several dreamless hours.
