Re: Sarah (Caulder)
After the injections were administered, Sarah didn't have too long to wait before she felt a strange feeling in her loins. Her balls trembled as the little critters inside wriggled about, and suddenly they began thrashing around a lot, making Sarah orgasm uncontrollably, yet still unable to spurt her seed and get the relief she so desperately needed.
"Ngh... I c-can't stand it anymore," Nell panted aloud before looking down at her throbbing shaft.
After a minute into the thrashing about of the little Kythal spawn, Nell cried out and began stroking her shaft furiously in a vain attempt to make herself cum, one of her fingernails picking at the tight little tentacle ring around the base of her shaft to try and get it loose so she could cum. It was completely useless however for Nell, and Sarah too if she tried to pick hers loose. Every so often, Sarah could swear that she saw the tip of a tiny tentacle poking out the tip of her shaft, flicking around before retreating back inside, but she couldn't be sure.
"Hmm, it seems like it's working somewhat, but backfiring at the same time in that they perk up with more cum. It is giving them more to feed on though so they're growing at a much faster rate than before. Their sizes have already increased by three percent as opposed to the half a percent from before the injections," Vicky said just before Sarah saw a compartment open above them both as two onaholes connected to tube came down in front of both girls. "Here you two, get these over your dicks, and I'll turn them on. At the very least the pleasure will nearly knock you both out so that it's not so hard to endure," she added, urging Sarah and Nell into inserting their cocks into the devices.
Nell did so without a second though, the very real looking pussy lips too enticing to not. Sarah couldn't resist doing so either and once both of their cocks were inside as far as they could go, they felt the fake lips tighten around their cocks like a vice grip before loosening just enough to allow them to slide up and down their lengths. Vicky giggled before applying some lube on their shafts as well and lubing up from inside the toys so that they could speed up without any pain.
Sarah felt the straps of the chair she was sitting in lock down over her wrists and ankles to keep her from thrashing around so much, and another wrapped around her waist. Nell was a little tougher to bind down, with Vicky having to think it through before using the bed's straps and locking her down on the bed while the devices whirred and hummed away. As soon as Vicky was sure the two were bound down enough so they didn't hurt themselves by thrashing so much, Sarah felt the onahole around her cock speeding up to a very fast pace.
As Vicky had stated before they started, it was turning into pure denial hell. Sarah felt orgasm after orgasm rock her body, making her body tense and relax almost constantly. Within about five minutes of starting up the toys on them both, Sarah's cock was so sensitive that she was orgasming almost constantly now, with no end in sight as the Kythal spawn in her balls seemingly grew and grew, which in turn made her balls grow larger and larger. Nell was whimpering with each breath, but looked like she was really enjoying herself despite the situation.
After half an hour of the toys going to town on them, Sarah felt them slow down a bit and it gave her a small breather. "Analyzing... Kythal spawn have grown thirty percent altogether. If I'm right, then at this rate they should only have to grow for another two hours before it's time for them to come out," Vicky said after doing another analysis on the two.
Sarah immediately felt the toys start back up, and she could swear that Vicky had a mischievous grin on her face as she ramped up the pace of them to twice as fast as before. Sarah's balls had increased in size again to the size of soccerballs and were still growing. She could see the wriggling inside them growing more and more pronounced as the spawn inside of them grew larger.
...
After another half an hour, Sarah was barely able to think straight and the sucking motions of the toys were still going at the same speed as they were half an hour before. She had experienced at least another thirty orgasms in the last half an hour, one per minute.
Nell meanwhile was lying limply on the bed, the straps not even needed any longer, though they still remained just in case. Sarah could see Nell's eyes were completely glazed over and she was barely thrusting her hips up to meet the toy on its way down.
,,,
Another half an hour passed by, with Sarah's poor cock so sensitive that she was beginning to experience a fresh orgasm every few seconds before the last had even finished. Her balls had swollen even more now as well she could see, now being at least the size of basketballs. Nell was drifting in and out of consciousness from the looks of it, moaning softly in her unconscious state as well.
Vicky had added another toy to the mix and had lowered down a couple of small rubber paddle devices that had multiple paddles on them in a wheel shape. She maneuvered them around to Sarah's and Nell's balls and turned them on. Sarah watched as the things started up, going upwards and lifting their balls up slightly as they slapped them with each one. The paddles were large enough to get quite a bit of their balls, but Vicky added another couple of the devices on both girls to ensure that there was maximum coverage.
"Let's stimulate them more girls. The more cum, and the faster you produce it, the sooner those things will come out," Vicky told them, lowering down more robotic arms from the ceiling with various things in their hands.
Three of the new ones each had feathers in their hands, which were used to tickle Sarah's and Nell's balls. Another couple by both girls had massagers in them which they pressed against the undersides of their hefty balls. And lastly a couple of robotic arms next to each had large menacing looking hands that were playfully groping and massaging the girls balls along with all the rest, to enhance the stimulation of their testicles and force them to increase sperm production.
...
After the last half hour that Vicky had said was required, Sarah was now literally in a constant state of orgasmic euphoria, as was Nell it seemed. The constant stimulation and pleasure was the only thing keeping her from fainting from the overload. Their poor balls were the size of large watermelons, and the Kythal spawn inside were noticeably larger with the wriggling shapes having grown steadily the entire time they went.
The tiny tentacles at the bases of their cocks were stretched to their limits it looked like, and near snapping. "Alright girls, come on wake up, I know it's tough to think straight but listen up. When those things snap, birth those critters in these buckets. I can study some of them and you can do whatever with the rest. I'm going to ramp up the pace and stimulation even more to try and coax those things into snapping so you can birth them. It's almost done now, just try and hold on a little longer... I think," Vicky told the girls, though Nell was barely listening, and Sarah could hear her AI companion, though it was up to her if she actually listened or responded.
Another ten minutes passed, with the toys going faster, harder, and a little rougher. Then another ten minutes passed, and another. After that half hour, Sarah could tell that Vicky was looking worried about them. The thin tentacles refused to snap no matter how much stimulation the girls got, and the Kythal spawn refused to try and come out, having gotten a taste of heaven and not wanting to let it go so soon.
"Girls, I'm going to have to knock you out before your minds take permanent damage from the over stimulation," Vicky said after another ten minutes of the things refusing to budge.
Sarah felt a mask descend over her face, which forced a gas into her face and forced her to breath it in, with Nell experiencing the same. Her last sight was of Nell's head slowly thumping back onto the pillows.
...
When she woke up again, Sarah felt immense pleasure and as soon as her eyes focused enough she saw Vicky's holo image next to her. "Sarah, I had to keep you both knocked out for six hours. I finally thought up a solution for these little buggers. It seems that the injections made you both produce too much cum and with the overabundance of food they didn't want to leave," Vicky told Sarah through the haze of pleasure, and looking down Sarah saw her balls were huge, twice the size as before when she was knocked out by Vicky. "Don't worry about those, they'll go down once those buggers are out of you, though there may be some permanent size increase, not sure yet. But I have a solution. Since we've already overfed them, we got to keep feeding them more and force them to grow too large to remain inside without killing the host, which I doubt they'll do," Vicky then explained, the toys already prepared to resume the stimulation from before.
"I've given you a shot of adrenaline to keep you sane, but it won't do anything about the amount of pleasure you'll receive," Vicky said, with Sarah noticing Nell awakening too. The toys picked up where they left off, and another injection of the stuff from before was put into both girls.
Over the course of the next two hours, Sarah watched her balls steadily grow more and more until they were dragging the floor, and the amount of robotic arms increased as they went, to keep the stimulation as spread out as possible. Nell underwent the same treatment. Soon after passing the two hour mark, Sarah felt something tremble in her balls that was different. "Hold on, something's different, something's off..." Vicky said moments after Sarah felt this.
The tiny tentacles at the bases of their cocks snapped loose suddenly, and Sarah watched as a long tentacle reached out of her cock as the onaholes lifted off of both girls, where it spiraled down her shaft and began stroking it. Nell was having the same thing done to her. The tentacle kept spooling out length which it used to coil around Sarah's immense balls, with Nell's doing the same thing, and then they felt the tentacles squeeze their balls. Sarah felt the most powerful and intense orgasm she'd ever felt in her entire life wash over her. It was so powerful that she fainted again for nearly two minutes, and when she came to, she saw a second tentacle had joined the first, and was squeezing her balls along with it for another intense orgasm.
A few minutes passed by and Sarah saw a third tentacle work its way out of the head of her cock, and then they all released her cock and balls and grabbed hold of the sides of the chair she was in, while Nell's tentacles grabbed the bedside. A bulge, rather large in size, began working its way up Sarah's length, followed by another, and another. About the size of a small brain, Sarah saw Kythal after Kythal spawn birthed from her balls. She still couldn't cum, but with each one that exited her balls, their size decreased steadily.
Soon she could tell there was only one left, and it was obviously the largest one, as they had only increased in size as they came out. It hung about halfway up her length, and she suddenly felt all the rest of them assault her balls with their tentacles, tickling, spanking, squeezing, massaging, and otherwise stimulating them until another powerful orgasm struck and the last and largest Kythal spawn burst free as her cock quickly shrank back to is original size, and what followed the final Kythal spawn was gallons of cum as her balls that were still the size of three or four watermelons each began spurting their bounty finally.
The tentacles of the little Kythal spawn groped her cock and pointed it down towards them, and since she was still strapped to the chair she couldn't stop them. Nell was in the same boat and the three gallon buckets that Vicky had left there were soon full of their cum and replaced by another of the same size. Nell just barely managed to fill the second bucket full,while Sarah kept cumming and nearly filled a third bucket full, with the Kythal spawn climbing into the buckets and swimming in their seed.
Sarah's batch of Kythal spawn seemed to enjoy teasing her more than Nell's did her, as five of them climbed back up onto her and with their small mouths and tentacle like tongues, they coated her shaft with their aphrodisiac saliva, which even the small ones had apparently. The largest one of Sarah's pressed its breeder tentacle against the tip of her cock and thrust it in, and being smaller than its sire's breeder tentacle it slipped in easily enough. It fucked Sarah like that for a couple of minutes until she came again and her cock finally gave out and began going limp after hours of almost pure torture.
"Sarah, I'm detecting a mass in your balls still remaining. It's smaller than those, but still present," Vicky said, bringing the viewscreen up in front of Sarah, where she saw the scan show a small growth attached to both of her balls in the middle between them. "It's fused to your balls and from what I can tell it's increased your sperm production threefold. And it's also making them constantly produce more cum. You will need to be milked every so often until I can find a means of reversing this, or risk getting blue balls that prevent you from resisting any advances of any beings on this world, or any world. Gods the Asari sex deviants would love to have you now. Your cock leaking cum like a broken faucet for them while they have you tied up in their pleasure dungeons," Vicky went on to say, commenting on the Asari and giggling before looking down at the Kythal spawn.
"I want those three largest ones for study. And the three largest of Nell's as well. The rest you can do whatever with, preferably far away from here though if I may make a suggestion," Vicky told them both, with Nell merely nodding wordlessly, looking very exhausted as her dick lay limply against her body.
Vicky then unhooked the straps holding the girls in place, letting them move again if they felt like it, though Nell didn't at the moment. Looking down at her balls, Sarah saw that they were about the size of baseballs now, having shrunk back down a lot. The smell of sex and cum was very strong in the air, and Vicky began trying to circulate the air some for the girls and lowered a device down to begin sucking up an entire bucket load each of their seed for safe keeping.
