"Oh my gosh, Lilith!"
"I know Maria. That. Was. Fucking. Insane! Aw man, if this is what being a testicle is going to be like from now on, then count me the fuck in. I've never cum so hard in my life. It felt like my entire body was exiting out through my pussy!"
"I... Yes, well I also liked it a lot. This is super wierd right? Or is it just me?"
"Haha, nope, I also find all of this to be crazy. I never imagined that one day I would wake up as a literal testicle, and absolutely love the shit out of it. The only thing that would make this even more perfect is if you were the cock and I was your balls."
Maria just stared at Lilith. "I actually, as hard as I am finding it to be, completely agree. I would absolutely wish to be your balls if you were my cock."
"Talk about sentences that we never have said before, haha."
"Haha, no kidding."
Lilith tried to maneuver herself closer to Maria. After a few tries, she managed to press herself up against her. Then she started to make her body shiver. The feeling of rubbing up against eachother like that felt amazing as they were still extra sensitive. "Hehe, this is so weird" laughed Lilith.
"Hey, do you think she will wake up if we get her massive cock to cum again?" Asked Maria.
"Wow, bold today aren't we. Usually you are more reserved and... PG. You feeling alright? I mean, I am also loving this new, kinkier Maria too. I am just a bit curious. One minute it is you being all shy and cute. Then the next minute you are shouting at her to stuff us deep inside her cunt. To be honest, I was kind of amazed that you didn't spontaneously combust after saying that."
"Hah? Is that so. Are you saying that I am too pure to talk dirty?" said Maria sarcastically.
"Definitely. Buuut, now that lewd Maria is here, it would be a shame to waste such an opportunity. Ooh, we are already swelling again!"
"Yes! Keep up the shivering Lilith. It feels so fucking good! Yeah, inflate us up nice and big like a couple of balloons."
"Rub your pussytube against mine Maria!"
"Uuugh, what? Wait, why am I still so hard?!" Said Dr. Vergunstien who just now was waking back up. She could hear the girls but was still too out of it to comprehend what exactly they were talking about. But at the moment, the only thing on her mind was cumming again. She could already tell that her second load was nearly ready, and a visual check of her balls confirmed that the both of them were all nice and swollen full of her semen, ready to cum at any moment. And as if it was meant to be, she crossed that threshold right as she had this thought.
A second semen shower coated her body, and she felt her consciousness slipping, but unlike last time, she was better prepared for it and managed to not pass out. However it would be a bit before she could properly work her legs again, as she had lost all of her strength below the waist.
Back inside her transparent scrotum, Lilith just finished pumping out her last bit of semen. Still looking at Maria, she asked "so, round 3?"
Before Maria could answer though, Dr. Vergunstien interjected. "Oh no you don't. Remember me? Your host? Or that I still have a job to do here? Dont get me wrong, I appreciate the love, but I'd want to keep getting off inside of a building that I own, rather than out in the cold as a homeless. So you will need to quit it for a while, at least while I am working with a client, or in the lobby. Aside from that and while I am in the surgery room, it doesn't really matter where I am. As long as it isn't while I am in those areas, cum away my lovely testicles. Just make sure I can still do my work when and where I have to is all I ask. So if I have a client in 3 minutes, that isnt the time to try for a quicky. Understood?"
Lilith and Maria stopped their shivering and seperated. Both testicles were content for now and wouldnt mind a bit of a recharge. Making so many gallons of semen, and then pumping it out with force through a thin tube was hard work, even if it was blissfuly pleasurable. "Alright, just let us know when we can start up again" they said in perfect unison as the settled down side by side. Now that they had no reason to cum, they simply watched Dr. Vergunstien work through her transparent scrotum.
Seeing how much cum they actually made had left them feeling very proud of their acomplishment. It was odd at first, feeling pride over sperm production. But they were just human shaped testicles, so it was obvious that they would start feeling happy about it as it is and will continue to be their only purpose in the world for the rest of Dr. Vergunstien's life. And that exact though is what made them so happy. That they would stay together, forever.
After spending an hour cleaning up the room with a hose and mop, Dr. Vergunstien decided that she needed a proper shower instead of just using the emergency shower out of convenience. So, while still caked in her own semen to the point she looked unrecognizable as the thick layer of cum covered most of her body, she walked upstairs and into her attached apartment. It was a studio style room which was perfect given her now much wider and taller frame. It was a bit awkward sidestepping into the room as her door was not big enough to let her walk through normally anymore. At least her 12 foot ceiling was still taller. She would definitely need to rebuild the place a bit. But a shower was needed before any of that, and then she had to work her shift today after that.
The warm water felt nice against her artificial scrotum. Her testicles agreed as well since both of them rolled forwards and pressed themselves into the transparent membrane of the scrotum. An interesting thing happened about half way through showering though. Before anyone realized it, both of her testicles had swollen up slightly. However, it was not from arousal this time.
Dr. Vergunstien's urethra was so wide that the shower water began to slip down into it, and eventually made its way into her testicles. Lilith and Maria were enjoying the new warm sensation comming from inside their former womb, now semen staging cavity. Both of them were having fun alternating who would push out the water next. Every time they did it, Dr. Vergunstien felt like she had just cum a little bit. Of course that wasn't the case, but she wasn't denying the sensation was very similar. One time though, she shoved her arm down inside of it and had it act like a plug. When Lilith went to take her turn, she felt an enormous resistance and ended up pumping her water into Maria, who then returned the favor.
When the shower was done with, and the testicles had pushed out all of the remaining water, Dr. Vergunstien cleaned herself up and got dressed, now only wearing her top, lab coat, and heels, as she no longer owned any kind of pants or skirts that could fit her enormous cock and balls. Not that she would ever cover them up anymore anyways. She made her scrotum transparent for a reason after all. Now dressed, she reentered her lab and went to greet her next patient.
