In all his eighteen years or so of being alive, going to the doctor's office was never fun. Much like having a finger shoved up his butt, though as miserable as that was it was still a long way from what Thomas was feeling right now. Especially since his chastity cage had just been removed an hour or so ago, and so sitting there in the lobby of the waiting room he really couldn't be blamed for not wanting to stay still. Against the feeling of his member rubbing against the inside of his jeans, it was all he could do not to have an accident right then and there in front of everybody else.
"Stop moving around so much," said his mother, "It makes you look anxious."
She shot him a chastising look for what must have been the fifth time in a row, and he grit his teeth as he forced himself to turn around. Beside him Sarah did the same, no doubt feeling the usual absence of her ben wa balls, and after so many weeks of being denied she was practically a barrel crammed full of dynamite just waiting for a spark. The only difference was that she didn't have a prostate gland like he did filled with old and aging spunk, and against the pressure rising up from just behind his balls it almost felt as if a single touch was enough to set him off.
Closing his eyes, Thomas took a deep breath as he tried to calm himself down. He couldn't, not right now. Not in public. The fact that he could feel his mother's eyes boring into the back of his head was not helping at all.
"How much longer do we have to wait?" he complained.
"Be patient now," she said, "It's only been fifteen minutes so far."
"But the nurse told us it would only be five," he said.
"And so maybe they're behind schedule," she scolded, "Do I look like I control the time?"
She frowned, clearly in disapproval, and very wisely he chose to keep his mouth shut. At least before he ruined his next chances of a release any more than it was. The fact that his member was unlocked right now was already a luxury that he could barely afford, and one that was going to cost him if his hands happen to wander a little too far. Just like he had been tempted to do for the entire last hour, and he swallowed hard against the thought.
Briefly, his eyes moved over to Sarah. Was this how she felt all the time? Her clit fully accessible to her underneath the thin cotton of her panties, and yet still unable to touch? Or was her self-control just that much stronger than his, and so the temptation didn't bother her as much.
The soft lights of the ceiling hummed away above them, and he tapped his fingers against the chair he was sitting on. Tough, like a thick layer of canvas, and he shifted his legs a little further up. The only thing that resulted from the movement, however, was that the crotch of his jeans was drawn even tighter, and he winced as he felt his member being pressed down against his balls. Which did not take kindly to the treatment at all, and proceeded to notify him quite loudly of their discomfort.
Son of a female dog. He never thought he would ever be thinking about this, but for once he almost wished he had his chastity cage back on. At least then it would protect him from all the rubbing after having spent so long locked up.
"If you do it in your pants, I'm never going to forgive you," said Sarah softly.
In return, he turned to glare back at her as if it was all her fault. Which it might as well be, since she was the other fifty percent of the problem. One minute was a very short amount of time when she spent at least a quarter of the overall length just trying to line herself up, and then had to pause every couple of seconds to prevent herself from going over the edge while he tried everything he could to cum.
The memory of last week rose up inside his head, and he clenched his fists together as he struggled to sit still. It was a dilemma that they hadn't yet figured out how to solve. Go too fast, and she would be forced to stop. Go too slow, however, and then neither of them would get to feel any pleasure. At the very least though, it beat having to suffer through the torture that was her blowjobs. Somehow, even after all this time she never really seemed to enjoy the idea of having to put his dick in her mouth. Strange how some girls could be so prude when it came to sucking off their brothers despite all the practice she already had doing so.
"Now, now," said their mother, "No fighting in public. And sit down properly. You too, Sarah. Don't think I haven't noticed the way you have your thighs pressed together. Remember what we talked about before we left?"
"But Thomas is doing it more," said Sarah.
"Yes, and I'll make sure to check him afterwards as well," said their mother, "Ten with the paddle if I find so much as a single drop of precum or arousal, just like with you, and so I advise you to stop teasing him so much and start focusing on yourself."
She raised an eyebrow as she clicked an imaginary remote, and Sarah turned a brilliant shade of pink as she glanced back down. Her legs snapped shut even more, and from the look on her face if her nipples weren't already stiff from before then they certainly were now. The vindication was only just starting to settle in, however, before they were finally interrupted from their innocent little family get-together, and Thomas glanced over to see a woman waving at them with a smile.
Dr. Harlow, her nametag read. She beamed out at them from behind her glasses, and with the soft strands of her hair tied up behind her in a ponytail she looked more like an older sister just out of college than the experienced medical professional she was. All the same though, he was more than used to seeing her face by now, and so pushing himself up with a sigh he slowly walked over. Sarah followed behind along with their mother, and together the three of them made their way down the hall.
"So," said Dr. Harlow, "Finally starting to grow up on me now are you, Thomas?"
She glanced over at him as they walked, and with a start Thomas realized that he was taller than her now. Which wasn't that impressive at the end of the day, but if nothing else it was a sign of how much his body had already grown.
"I guess?" he said.
It was a weird thing to think about at the moment. Especially as Dr. Harlow continued on.
"Speaking of which," she said, "You must be getting quite the attention as a young man now. Any girls at school you like? Girlfriends maybe? Or perhaps a boyfriend or two?"
"Uh, I don't...," sputtered Thomas.
"Or does your mom still keep you on a short leash?" she teased again, "They can be like that, you know. Especially since it's so hard for them to let go."
She turned her head with a knowing look, and there was an awkward moment of silence as their mother returned the gesture with the exact same smile. Wickedly, and like a shark, thought Thomas, though if the doctor ever noticed the strangeness of it then she paid it no thought. At least for the rest of the journey through the clinic before they finally found themselves standing in the middle of an empty room, and he blinked as he looked over at the various instruments that lined the shelves.
To the side, there was a rather inconspicuous examination bench placed against the wall.
"Are we...?" he said.
"Together as always," nodded Dr. Harlow, "Courtesy of your mother, though after all this time, you'd think you would have already gotten used to seeing your sister naked by now."
Or maybe more than used to since it wasn't as if she knew about their exercises at home, but somehow it didn't exactly feel appropriate to bring that up right now. Even as the doctor walked over to open up the cabinet, and Sarah shot him a look of death as she reached over for one of the gowns. Turning away to pull her shirt up over her head, she reached over to unclasp her bra. Then, with the shallow curves of her nearly flat breasts fully visible, she stripped free of her panties along with her skirt.
There was a brief flash of her privates the opening of the robe as she turned around. Thomas blinked in response. The entire thing took less than a minute for her to get changed, and if weren't for the fact that she hated being seen like this then he could have sworn she did it on purpose. Not that it mattered anyways as she walked over to stand in the corner and sulk. There, she seemed to say, glancing over at him as if it was now his turn. Which it probably was, and so biting down on his lips, he forced himself to reach down. His top went first since it was safer, the collar of his shirt catching against his neck before he remembered to undo the buttons, and then it was onto much more pressing matters as he felt his heart speed up.
Slowly, one step at a time...
As long as he didn't think about it then there was nothing to worry about. As it was though, he could already feel his member straining against the fabric of his jeans as he slid them off. Past that, there wasn't much left for him to do but reach over for his boxers, the color of which perfectly matched his ears at this point, and the entire situation was only made even more humiliating as he was forced to stretch the waistband of his underwear past his erection to prevent it from catching any more than it already was. All four inches of it standing up stiff like a flagpole as it pushed the material away from his crotch, and he winced at the heaviness of his balls.
"Excited now, are we?" said Dr. Harlow.
"Sorry, I didn't mean to," mumbled Thomas, "It won't go down."
The only saving grace there was that at least he didn't have to go first. The doctor reached over to snap on a pair of gloves, and Sarah hopped up obediently onto the examination table. All good-girl-like as well with her hands by her sides, legs placed neatly in the stirrups, and a distant hint of promised manslaughter if he so much as dared to look. There wasn't much else for him to do though, and so he ignored it as he glanced over to watch as the doctor slowly spread her apart.
From the angle he was sitting at, it was a bit like watching a flower slowly unfurl.
"Look at you," said Dr. Harlow, "All grown up now and mature. And your tiny little bean down here is even starting to stand up."
She placed her fingers on either side to peel back her hood, and Sarah made a sharp sound of discomfort as the smoothness of the glove brushed against her nub.
"I don't...," she said.
"Though it looks like you're still shaving yourself smooth," continued Dr. Harlow, "Speaking of which, judging from your reaction, it might be time for you and your mother to start having that talk."
Whether she meant the wonders of masturbation or the dangers of pregnancy was hard to tell, but there wasn't much time to ponder the question as she waved for Sarah to turn over on all fours. There was another flash of skin as she lifted her bottom up, and then reaching over for the familiar jar of lube the doctor applied a generous amount of the substance between her cheeks before pressing down. There was a brief moment of resistance as Sarah gasped out loud, and then the room was filled with the sound of something slick as the doctor slid her fingers all the way forward past the tightness of her rear hole.
"Oh!" said Sarah again.
Her voice soon cut off a moment later, however as she seemed to curl up. Like she was trying really hard to pretend that she didn't exist right now, especially with their mother still looking on.
Slichk, slichk, slichk...
Slichk, slichk...
Slichk.
The sound echoed out into the silence of the room, and under the relentless movement of the fingers and the thermometer that soon replaced them, it was hard not to notice the gradual shift in wetness as Sarah let out a moan. Her labia opened a little more, and between the up and down movement of the thick glass rod, Thomas could almost see the opening of her tunnel as her arousal spilled out. The instrument pushed past the opening of her anus again, and bit by bit like the thawing of a glacier, a single strand of crystal-clear fluid stretched out through the air before finally making contact with the parchment paper below. Like that, the stimulation went on, and it wasn't until a second and then a third drop joined the growing patch of dampness that the thrusting finally stopped.
Leaving the device buried halfway inside, the doctor looked over to measure the results.
"Ninety-eight point nine degrees," she said, "A bit hot, but given the circumstances, I'm sure it's normal."
The same couldn't be said for the rest of the situation, though, and Thomas swallowed hard as she waved for him to stand up for his turn. There was another rush of air as she lifted up the front of his gown, and closing his eyes tightly he tried not to shiver as he felt her hand pressing down just to the side of his member. Tap, tap, tap, her fingers went, tracing a small circle around the base of his shaft as she reached over to cup his testicles, and against the tightness rising up in his stomach and the wonderful view of Sarah still bent over in front of him with her bottom raised up, it was all he could do not to melt into the floor.
"Such a healthy boy," murmured Dr. Harlow.
Her fingers continued to dance across his flesh, and he felt the pressure inside his prostate spike up another notch. Briefly, she reached over to press against his perineum. Oh god. His face was red as a tomato now, and already he could feel just the tiniest bit of precum leaking out. Just a little more, he thought, and he was sure he would blow. The only problem was though that with his mother still watching from the side, there was no way he could get away with such a blatant disregard for the rules. Like, even if it wasn't done by his own hand a climax was still a climax, and if she saw so much as a single drop of semen made it past the tip of his urethra, then he was in for a world of trouble.
As such, biting down on his lips, Thomas forced himself to stand still. Even as the doctor reached over to peel back his foreskin before forming a ring with her thumb and index finger and sliding it all the way down. Like a sheet of silk, only much more frustrating as it pushed him closer and closer, and by the time she let go again, he was practically begging for her to stop. In his head of course. There was no way he would ever jeopardize his next scheduled release by acting so obvious.
"Well then," said Dr. Harlow, after some time, "Seems like he's a bit pent up, though aside from that everything looks normal."
Their mother took the news with a surprising amount of stoicism for someone who knew so much more.
"And is there anything else?" she asked.
"No," said Dr. Harlow, "Though there is a bit of chafing along the side. You might want to have a little talk with him as well about easing off a little between his... let's call it the time he spends alone."
She leaned over a little more, her face growing way too close for comfort, and for a moment Thomas wondered what would happen if he thrust his hips forward against her mouth. His member let out a pathetic little twitch, and she smiled in response as she reached over to gather up another shameful drop of precum. Thankfully however, they were soon off to the other parts of the exam as she walked over to lift up the other side of his gown, and with the material gathered up around his waist like a dress he winced as he felt the familiar touch of lubrication against his rear hole.
"Cough for me," she said.
Her finger pressed up between his cheeks, and he signed at the frustration of it all. At least they were close to the end now, even if his balls felt like they were about to explode. Never mind the fact that it had been almost an entire year now since he had last been allowed to cum. If only he had another way of relief that didn't involve his sister bouncing up and down in his lap as she desperately tried to hold back a climax of her own. But that was a topic for another time.
Spreading his legs apart, he let his eyes wander across the room. From the top of the examination bench, Sarah glared back at him with the end of a thermometer still sticking out of her anus, and he shrugged as he felt the doctor place a similar device against his rear hole as well. Right, of course. Let her look all she...
