I signed up for these experiments, not really knowing what I'd be in for. Just an average laquine, fresh out of college and I've only had four kids myself, probably fathered a few, but who keeps track of that. Figured I need to pull my weight more, really help populate our new planet. That's what my species was made for after all.


So they send me some pills. But the label says they are for 'urethral use only.' OK. There I am, in the living room, as we watch TV, shoving these pills down my horse cock, one by one. Sometimes I'm pushing them in, sometimes its one of my girls doing it.


An hour in, and I can feel my testes burning. Just heating up. Didn't really notice what it was at the time, just asked one of my girls to turn up the AC. Now, mind, I'm doing all I can, so I've already got them all baking new buns in their ovens, probably mine, but maybe they got knocked up at school, I don't give a fuck. Point is, every laquine in the house is pregnant but me at this point. My girls know our job on this planet. We are baby makers, and that's what we're gonna do. No slouching in my house. 


I mean, yeah, I'm a programmer for the weather control satellites, but that takes maybe four hours a week. Sixteen when monsoon season hits.


Anyway, three hours in, and my cock's getting mighty sore. Thought it was just from shov'n so much into it, but I've done far worse and not felt this much. No, this was something else.


See, I didn't read the dosing instructions right. It said to take one every six days, but I got it in my head I was supposed to shove one down every six minutes. So, I've downed about three months worth of these pills into my shaft, I'm naked, sweating, throbbing hard on, my boobs are itching something fierce, and there's not even anything good on the TV anymore. Who schedules these shows? By midnight everything sucks.


I can't get myself to keep pushing the pills down, then I pass out. That was maybe, 1, not far from my regular bedtime, really, but I don't normally sleep on the couch. I like my bed.


Anyway, I wake up, and realize, my cock is HUGE. I mean, I wasn't small to start, but I mean it's bigger than both my legs together. No, bigger, cause I did put one of my arms down my urethra. Thought maybe I could grab some of the pills, stop this from getting worse. I don't know. I was panicking. They were probably all dissolved anyway, but I couldn't even reach down to my crotch that way, not with how stiff I was.




And it was still getting bigger. As I said, we were panicking. So my littlest girl, only three months pregnant, gets the idea to jump into my cock to get the pills. I assume that was hir goal, since I'd been yelling my intent to grab them not long before shi did it. My cock was pinning me to the couch, so I couldn't exactly stop hir. 


Shi wriggled on down, and it got to feeling really good. My shaft seemed to help pull hir down deeper. When I orgasmed, I was expecting a powerful explosion of cum, or something, but I felt only a subtle shift around my girl as shi was pulled up into my belly. It felt just like being pregnant with hir again, but even bigger.


With the other girls' help, we got me out of the house before I was too big for the doorway. So, laying out on the lawn, I suddenly start having a bunch of little orgasms. Each one feels like it's trying to push something up my new cock, which, still hasn't stopped getting bigger.


I'm tired, horny, and all these micro orgasms are just unsatisfying, edging me like no Dom ever has. Finally, one of the objects I've been pushing gets to the end of my shaft and it's a sperm the size of my head, flagella as long as my arm.


This thing thrashes around on the grass useless. But more are coming. And the next one to flop onto the ground, well it's got more coordination. It manages to actually pick a direction at random and get going. Third one moves with intent. These fuckers are learning with each iteration.


I don't know how many more, but I saw at least thirty on the lawn around me when I hear one of my girls saying that a sperm has hir my the ankle. I look over, and I see shi's fighting the sperm hard, but it's binding hir arms. Then another one forces its way between hir legs, opening hir teenage birth canal a couple months early. It climbs in and writhes around a bit. Couldn't tell what happened.


Now, this whole mess has been gathering spectators. People from all over the neighborhood are standing just beyond where the sperm have been stopping. On occasion, one would get close, and someone would stomp it to goo.


But then I feel just, a massive orgasm coming, my shaft is now bigger than half my house. And when I finally release, oh god, did that flood feel good. And a flood it was. My massive shlong erupted like a volcano, flooding the yard with fluids that revitalized all the previous exhausted sperm. With the liquid, they were able to move much better and started assaulting the observing neighbors. Some tied them up, others forced their way into their wombs, or ass, they all looked six months or more pregnant.


I live in an almost all laquine community, so just tons of bunny women with big horse cocks. And bow that they are in my goo, their breasts and cocks start to grow as well.


Oh, yeah, I forgot to mention, my melons by this point were each bigger than my oldest daughter. Just massive chonkeroos. But now that I'm surrounded in seminal fluid, some of the randy sperm sells start working at my nipples. At first, they can't do anything but jam their spermy heads at them, but eventually they start using their flagella to open me up first. I think each breast took about five or six of the sperm inside before they were just too full.


Similarly, some of my neighbors, their cocks were starting to get big enough for some of the sperm to dive into them. Now, laquines have internal testes, part of our ovaries. So when I saw what happened to the non-laquines, I started to understand why mine had been hurting last night. Their testes, their balls, grew massive, bigger and bigger with each sperm that wriggled into them. This then accelerated their cock growth.


Within minutes, the non-laquines were spewing sperm cells as well. They were smaller than mine, but all the fluid around us made it easy for these smaller cells to travel between all the bound up bodies, entering us all again. They could even get into the smaller cocks and breasts.


There must have been pheromones everywhere, mighty strong, because the emergency responders arrived on scene and all started stripping their protective gear and masturbating while they got impregnated as well.


Looking over to the roof of my house, I saw my middle daughters had escaped up there after the flood, but the smell was getting them so horny they couldn't help but to fuck each other. At least they had the presence of mind to remember what I fought them about mutual penetration so they could both fully enjoy it together. I focused on watching them slip into and out of each other's slits for what felt like hours before sirens drew my attention away.


All around me, the laquines were as big as I was, each spewing sperm and fluids everywhere, up and down the road. I could see rotund bellies and balls all the way to the library and city hall and down to the beach.


Hazmat crews used fire hoses to wash away the fluid. It was a battle against so many cocks flooding the streets, but they slowly removed us all to isolated holding facilities.


Now they say I've got a dozen babies growing in my breasts, my youngest daughter is still inside me, and her unborn daughter is pregnant with triplets. Since shi's not actually in my womb, I'll have to birth hir through my cock once shi's ready to come out. But I don't think that will be a problem since I've been spewing all these giant sperm all week.


Anyway, yeah, that's all I can tell you about what happened. Hope it helps your research doc. I'll be here making more if ya need anything. Oh, and tell my middle girls I love them. I miss them. I've got my youngest in me, obviously, and my eldest is in the tank just over there behind you.


I guess one detail I forgot. About my middle girls. I'm told, they were affected a bit, probably, because when they were on the roof, they managed to impregnate each other's babies inside each other. So, yeah, I'm really proud of them. We'll fill up this planet in no time like this.
