Several months had passed since that fateful day when Flurry managed to seduce her uncle.

It was summer time and school was out, giving kids the freedom to do whatever they wanted. And as the sun rose on the Sentry household, Flash stepped into his kitchen to make a cup of coffee and start breakfast.

The man quickly put some eggs into a pan and placed it on the stove, bringing the water to a boil whilst toasting some bread. A nice high fibre diet. Perfect for the special girls in his life.

A few minutes later, he heard movement from the stairs and knew someone was coming. And sure enough, his beautiful wife stepped into the kitchen. Twilight Sparkle yawned, as she carefully made her way into the room.

Flash spun around and smiled seeing her, his eyes shifting to her large belly.

"Morning sunshine," he told the pregnant woman as she smiled back. He then noticed how tired she looked and realised she was clearly missing being able to drink coffee. "Breakfast is almost ready."

"Great," Twilight sighed, "I need to get to the lab soon."

"Bet you're looking forward to going on maternity leave, huh?"

"I guess. I just hope everyone else will be able to get the work done without me there."

"I'm sure they'll be fine." He moved over and kissed her on the head. "Right now, you need to focus on our own little science experiment." He pointed at the belly that was poking out of her robe.

Twilight laughed, as she headed into the dining room so she could stay off her feet.

As Flash took the toast out of the toaster, he thought about what had happened all those months ago. After his weekend romp with Flurry, he had picked his wife up at the airport and found she had a surprise for him.

Over the last few months, she had been working on a new type of fertility drug. One that had just been approved for human trials. She had been taking them herself and thanks to her new drug, she had been confident she would be able to conceive a child.

As such, the pair had returned home and Twilight had practically thrown herself at him. That had certainly been an interesting night.

And just over a month later, Flash returned home to Twilight running at him with a positive pregnancy test. Now, they were awaiting the arrival of their first born child. Something Flash couldn't wait for. Just one month stood between him and being able to hold a child he knew was his.

Flash smiled as he cut the toast up and took the eggs out of the water, as another set of footprints made him glance towards the stairs. And soon enough, the other important girl in Flash's life arrived.

Flurry Heart smiled at her uncle, as she walked towards him whilst resting a hand on her own enlarged belly.

Indeed, Flurry had also gotten herself pregnant after their weekend together. The revelation had come as quite the shock to everyone in the family, though only a limited number of people knew.

When Shining had learned, he had of course gone ballistic and demanded to know the name of the asshole that had done it. Flurry had held firm and refused to tell him the father's name, which Flash was grateful for. But the situation had certainly caused a lot of issues.

"Morning," Flurry told him before seeing what he was making. "Eggs and soldiers. Really? What, am I five?"

"Nothing wrong with eggs and soldiers. High fibre diet is great for you in your condition." Flurry moved up besides him and Flash took the moment to rub her belly, making Flurry moan as she loved the sensation.

"Protein's also great for me," Flurry's hand moved over Flash's crotch. "And I know where I can get a ton of it."

"Not now," Flash told her. "Twilight's in the other room." Flurry pouted. "Don't be a baby. She'll be heading out soon, then you can have all the protein you can stomach."

"I'd better. I'm not gonna get as much once she starts her maternity leave." She headed into the dining room to talk to her aunt, leaving Flash to finish breakfast and think about his life leading up to this point.

As soon as Flurry's condition was discovered, the family had considered what to do. Flurry refused an abortion, which meant the only real option was adoption. And when Twilight had announced her own pregnancy, it had been decided that she and Flash would adopt the child and rise along with their own under the notion that they were twins.

As such, the family came up with a story that would make it so nobody would know about Flurry's pregnancy.

The first thing to do was pull her out of school, Flurry completing her senior year through home schooling. The reason was stated that she developed a horrible illness and couldn't see anyone except a select few, Flurry quickly being moved into her aunt and uncle's place before the pregnancy started to show. Flurry agreed to pretty much house arrest, with Flash working from home so that he could take care of her.

Despite this, she had still managed to earn valedictorian and gave a virtual speech to her class at graduation that kept her lard stomach out of view. And with her being due during the summer, Flurry would be all set to start her college life as if nothing had happened.

Flash finished making breakfast and headed into the dining room, where he found Twilight and Flurry rubbing one another's bellies. "I think I just felt her kick," Flurry laughed as she felt her cousin in her aunt's stomach.

Twilight laughed, as she felt Flurry's. "Lazy little guy, isn't he."

"Oh, no. He's far from lazy. He's just a night owl." They both laughed at this, as Flash put their food down in front of them. The girls quickly started enjoying their meal, whilst also talking about potential names for the babies when they arrived.

As soon as Twilight finished, she got up from the table and headed upstairs to get dressed.

Flurry chose this moment to move her chair right up next to Flash and start rubbing her hand against his crotch. "No," he told her.

"Please," Flurry pouted, "I'm so horny. Pregnancy hormones are driving me crazy."

"Wait until Twilight's gone," Flash told her. Flurry frowned and moved her hands to squeeze her breasts, which were up two cup sizes now, together in order to try and entice her uncle. But Flash held strong and took Twilight's breakfast plate into the kitchen to clean.

As he did, he got a message from someone at work. Turns out there was an issue and Flash needed to look over a document being sent over by email. As such, he quickly dried the plate before heading upstairs and telling Twilight.

She understood and assured him he didn't need to see her off, allowing Flash to head back downstairs and into his home office. A rather large room with a desk, couch, coffee table and several bookshelves.

He quickly got his computer booted up and started looking over all the documents that had been sent, finding the one his colleague had talked about and beginning to look through it. The problem was soon made apparent and he quickly got to work making the corrections, completely oblivious to the time that passed.

By the time Flash managed to get the issue sorted, he had no idea what time it was. He knew Twilight had to have left for work, which meant only one thing.

"Flash?" Flurry cracked the door, "are you done yet?" Flash wanted to tell her yes, but he still had some fine tuning to do.

"I'll be finished soon." But then Flurry pushed the door open completely and stepped inside, giving Flash a view that he never got tired of. Her naked pregnant body, on full display.

"Alright then," Flurry giggled as she moved over to his desk. "Then I'll just get you started."

Flash rolled his eyes. "You are insatiable." Flurry giggled again and pushed Flash's desk chair back, allowing her to get between him and the desk. And with his help, she carefully got down between his knees before scooting back beneath the desk.

Said desk was quite large, so there was more than enough room for her under it. And as Flash rolled back, trapping her under it, she quickly undid his belt and pants before pulling his cock out.

Flash kept working, as Flurry got to work pleasing him. He moaned every now and then, but kept his focus and managed to get the document completed. And once he had it sent off to the right place, he quickly found himself getting overwhelmed by Flurry deep-throating him.

"FUCK!" He cried, sitting back in his chair. "You've gotten so good at that over the last few months. Flurry smiled around his cock, as she kept gagging on it harder and harder. Flash grunted and groaned at the sensation, his head falling back as he simply let himself get overtaken by the pleasure. And eventually, he couldn't take any more. "FUCK!" He shot his load right into his baby momma's mouth.

Flurry, having heard his out cry, pulled all but the head out of her mouth seconds before he started spewing his cum down her throat.

She quickly started sucking it down, swallowing as much as she could whilst savouring the taste. She sighed, feeling her belly fill up with her uncle's sperm. The same sperm that had turned her from a teen into a mother.

Flash sighed as he felt the last of his cum fly out of his cock, the man groaning as Flurry sucked on the end of his dick hard. "Good girl." Flurry giggled as she kept sucking on him, working to keep his cock from going soft. And before either of them could say anything, another voice spoke up.

"Having fun, are we?" Flash jumped, fearing Twilight had come home. But when he looked towards the door, he was greeted to the sight of another pregnant woman. Cadance.

The pink skinned woman was standing at the door, wearing a white summer dress that was bunched up around her expanded belly. Like her daughter and sister-in-law, Cadance was eight months pregnant.

Flurry pushed Flash's chair back and climbed out from under the desk, kneeling between his legs and smiling as she glanced back at her mother. "Hey mom."

Cadance began to move across the room, not looking the least bit surprised her daughter was naked and blowing her uncle. "Flurry. You really shouldn't be down on the ground like that. You might do something that could hurt the baby."

"I'm fine, mom." Flurry turned back to Flash and grabbed her tits, which she wrapped around his cock before beginning to massage it. "It's not like I haven't seen you in this exact same position, in the exact same condition. Now, are you just gonna stand there or are you gonna do what you came here to do?" Cadance sighed with a smile and shake of her head, as she and Flash locked eyes.

She then reached up and pushed the strap of her dress off her shoulder, the other one quickly following which caused her dress to completely slide off her pregnant body.

With nothing underneath, Cadance was now just as naked as her daughter. And as Flurry kept playing with Flash's cock, Cadance stepped up beside him and allowed the man to wrap his arm around her waist.

As she leaned down and started kissing Flash, the man couldn't believe how insane his situation had become.

Cadance had been the only one Flurry had revealed the secret of her baby's parentage too. The woman had been pissed when she learned the truth, but Flurry had admitted to the blackmail and showed her mother the film.

Despite still being angry, Cadance came to accept what had happened. And after Flurry had moved in with Flash and Twilight, she came over and found the pair in a similar situation to the one Flurry had found them in. After that, it wasn't long before Flash had both mother and daughter naked in the same bed.

"Fuck!" Cadance groaned, as Flash placed her nipple in his mouth and started suckling on it. "Oh god! My milk's gonna come out." Flash smiled around her tit and kept sucking, eventually tasting the liquid she was making for their child.

It was certainly a strange scene for anyone who might walk in on them. Flash, getting a titty fuck from his pregnant niece whilst he nursed on her equally pregnant mother.

Soon enough, Flurry had Flash back to full mast and smiled as she got up. Flash pulled away from Cadance's breast and watched her bend over his desk, pointing her ass at him and wiggling it to show what he wanted. And Cadance soon followed, standing beside her daughter and bending over to present herself to the man.

Flash got up and stepped behind Cadance, quickly pushing his cock into her already soaked pussy. "Oh," she moaned, "oh yes." Flash started fucking her, whilst Flurry pouted. But she was soon moaning as well, as Flash stuck his fingers into her cunt.

"Yes!" She cried, Flash fucking the two and driving them crazy with his cock.

He thrust into Cadance for several minutes, her large tits and belly swinging beneath her with every impact. Then, he pulled out and moved behind Flurry to do the same to her whilst he fingered Cadance. The two moaned, as they glanced over at her other. And after smiling, they both leaned closer and started kissing one another.

Flash smiled at the sight and kept fucking Flurry.

This went on for a while, Flash screwing one of the mother daughter duo before moving to the other. This allowed him to fuck the pair to several orgasms, whilst he remained far from needing to cum.

An hour after Cadance's arrival, Flash was no longer fucking them. Instead, he was standing with Cadance and Flurry beside him. The pair had their pregnant bellies gently pressed against each other, as Flash rubbed his cock between them. "Fuck," he whispered. "So good."

Flurry and Cadance smiled, as they felt his cock rub against their bellies. And eventually, Flash let out a groan before keeping the head of his cock between their stomachs. Moments later, his cum started spilling out from between their bellies.

The woman smiled and as they pulled apart, a trail of the white cum connected them and they started rubbing it into their skin. Flash sighed at the two, as he looked forward to another day of screwing the mother and daughter. "Shall we take this to the bedroom?"

Flurry and Cadance smiled at him, their head leaning against one another as they replied in unison. "Sure, daddy."
