Anal Babies? Yes Ma’am

Shepard couldn’t deny, not even for a second, that she would love to get someone pregnant through anal. It was just a simple fetish that it seemed like everyone with a cock had. Dr. Chakwas went to a filing cabinet close to the door and took a series of vials from it.

“There’s two vials of chemicals I have to treat her with. Both must be taken exactly five minutes apart from each other or else the serum won’t be able to do its magic. Once both have been taken, the subject will be completely ready for insemination.” She said. As she walked past, Jane couldn’t help but get a handful of her ass. Chakwas rubbed it against her exposed member while carefully injected the serum into her subject. “We have five minutes, Shepard. It would be best that I play my part in this experiment.”

The older woman fell to her knees and rubbed her face against the pulsing cock head. She placed both hands on it and strategically massaged it while kissing the tip with her mouth. For awhile she seemingly teased the Commander, so much so that she even caused her to roll her eyes at one point. Chakwas laughed and in a single moment—like the seasoned doctor she was—she engulfed the entirety of Shepard’s cock to the base without a single cough or sputter.

“Holy hell. That’s quite impressive Doctor.” She said.

Chakwas didn’t relent, she masterfully bobbed her head up and down, she built up her rhythm and noticed Shepard’s breathing growing more and more hazy. She unsheathed herself and before the Commander could object she spun her around and pinned her to the door. She pressed her face against Jane’s warm cheeks and licked up all of her anal juices. For three minutes she greedily ate out Shepard’s asshole until a timer went off. Not wasting a single second she rose and procured the second serum vial. Once it was administered she beckoned the commander forward to claim her prize.

The girl’s ass was exposed and lifted a few feet off of the contraption the rest of her body rested on and all this time she was ****. Shepard asked the doctor about it and she only replied that the “medicine” she gave her had lasting effects and would keep the girl knocked out under certain doses. Despite being ****, she seemingly tried to keep to her asshole tight as Shepard struggled to slip it in. In cases like this Jane would either have to wait for her partner’s permission to go further and take everything she wanted on her own whims. This was her time, so she surged herself forward and was able to bury nearly half of her shaft inside. She pulled it out then jammed it back in again. A minute of thrusts later and the asshole began to open up—the body started produces juices to help coat the transition as her cock travelled deeper and deeper till she felt the asshole open up into a thicker chasm. The popping feeling her head made excited her further as she pumped back and forth, trying to replicate the feeling.

Dr. Chakwas opened the girl’s mouth and slowly slid her cock head past her lips. Receiving no objections she pushed forward until meeting resistance. Even though she was ****, the teen still had control over her breathing and gag reflexes. Although it was disappointing, the older woman had fresh plans to make sure she trained the slut in the future. You couldn’t be a proper sex **** if you couldn’t take a foot of cock down your throat after all.

In the meanwhile, Shepard gripped the girl’s legs as she drove herself harder into hole. She felt herself close to cumming on multiple occasions, but she wanted to keep it going—build it up till she had a mighty eruption. At the same time, the pulling feeling the asshole developed wasn’t making it any easier. She ended up making a terrible mistake, wanting to take it easy and gain her composure, Jane buried herself and kept herself there thinking it would calm her down. Instead the feeling became too much as she thought about the possibility of getting her pregnant through anal sex. She wanted to fight back, but at the same time she wanted to blow her load. And she did so, letting out with a mighty growl. Her balls clenched and settled until the end of her orgasm. She could feel the cum seep through her anal cavity and around her shaft as it made the departure easier.

Doctor Chakwas held up a monitor to the girl’s stomach the holograph showed millions of sperm trying to break into one of the eggs—it was successful. When Shepard asked about the permanence of the serum, Doctor Chakwas said that that was the whole point of science: to experiment and log the results.

Shepard used her cum to pound the girl one more time before eventually leaving.

“You can visit any time Commander, I always knew it would be a good thing to have your expertise on board this ship.” Chakwas said as she watched the Commander leave her office. That being said, she had experiments to run and her next appointment wouldn’t be for another hour. It was time to give the girl’s cunt a shot now. If anal pregnancy didn’t work, then the good old fashion way would be the best option.
