Introducing the all new, second to none, period vaccine. This vaccine is guaranteed to prevent periods for 36-42 weeks(about 9 months). It is completely safe and effective, but there are a few side effects you should know about before receiving my easy, painless vaginal injection.

Oops, you got bred. A momentary mistake on his part and you're staring down at a belly that's getting bigger and rounder by the day. Accident or not, he's got his baby inside you now, and you have a lot more months to watch your body change and grow because of his 30 seconds of pleasure.

David Attenborough voice:

"Sensing ovulation approaching, the receptive female opens her legs to allow the male to enter. The male thrusts his penis deeply inside the female's vagina. The female secretes a slippery mucus from her cervix to further encourage the male. Suddenly, the male instinctively pushes himself into the female and stops. At this moment, he begins pumping his seminal fluid containing hundreds of millions of sperm cells into the female. The force of his ejaculation can reach 45 kilometers per hour, and this speed helps the sperm on their journey into the female's uterus and fallopian tubes. The race is now on to find the female's egg--only one sperm will penetrate the egg and add its genetic contribution to the next generation.

After several squirts, the male's ejaculation ends. Satisfied with a job well done, the male withdraws and begins his search for the next fertile female."

I may have said it before, but I'm amazed at how efficient the sperm meets egg part of reproduction is. If I ejaculate inside you the day before ovulation or the day of ovulation, there's at least a 90% chance that my sperm will find your egg. That doesn't always mean pregnancy, of course--many things can go wrong, including poor egg quality, dna damage in the egg or sperm, poor uterine environment, etc.

But if you pop out an egg and I squirt my cum onto your cervix, those sperm will find and penetrate your egg.

It was something just sort of happened. You had never seen each other that way before, but after the last guest from Mom's funeral left, it was only you two still left in the old house. Between your divorce and her long term relationship ending, you both found yourself well into your 30s with nothing to go back to. So you stuck around, stayed up late drinking, reminisced about the good old days when one night you just found yourself falling into each other.

The first night you went at it you could have sworn you were going to break her childhood bed you were so terrified of your desire. From there you violated every surface you could find, not one family memory would be left without a new association of your sweaty thighs or her hot ass.

In a few weeks when the passion wore down, you figured you would both look back on this time as your little secret. That crazy moon you were lovers. That was, until her test turned blue.

From there you weighed the options. You both agreed it wasn't the baby's fault, but that there was no way you could stay. You sold the house and moved across the country. You found a job, and she nested. The story would be she got knocked up off some old boyfriend and you were the brother stepping up.

Those next 8 months were scary, teeming with tension. Gradually the barriers began to break down, and the life of a brother and sister soon became husband and wife. One night she came into the living room and sat on an ottoman, her breasts plump and belly laying in her lap.

"You're still attracted to me aren't you?"

There was no hiding it. Your sister, the mother of your child, looked good to you. You made love that night slow and steady, window open, the last blue rays of light on her face. She fell asleep with her arms around you. You held her close knowing you had finally found your family.

Mom never saw herself having anymore children, but when her young pup went and knocked her up, she couldn't say no to him becoming a father. She welcomed new life into her old belly. You watched her bloom as her dirty little secret swelled and puffed out of all her belts and jeans until she could wear nothing both dresses. She couldn't be more proud to be giving birth again, even if her youngest was almost 25.

"Okay, your anus is fully dilated. We're going to start pushing now okay baby?"

You nodded in panic. Despite what the books had told you, there was no preparing your body for this. Not what the science was asking you to do, a boy becoming a mother. It was at this point your mom and sister flanked you on either side and held your knees apart.

You reached over for your sister's hand and held it tight. There is no one else you would have put yourself through this for if it wasn't her baby. You felt her tears fall off her cheeks onto your arms, the warmth of your mother's hand in your hair, rubbing up and down your head and neck, whispering gentle words of support.

You had tried to cling to some masculine dignity through this, that this all just a favor for a friend and that having a baby didn't make you any less of a boy. You had asked your father and brothers not to see you like this. But being here, surrounded by the ladies of your life, your midwife inside you, your bowels tensing in anticipation of pushing out your baby boy, you gave in. For at least that moment you were a complete woman, gushing with life.

"Okay! Ready and, push! push! push! push!"

I went to a prenatal clinic to confirm what I already knew and got an early ultrasound, I'm 13 weeks pregnant

I dont know who got me pregnant, I had so much unprotected sex...

You’d better get used to carrying that belly around. You’re going to spend so much of the next two decades with one that you’re going to forget what it’s like not to feel it.

At this point, a pregnancy pact was just a right of passage among any sisterhood. Good little college girls who agreed in secret to get knocked up behind their parents backs and help each other give birth and coparent in their little apartments. Usually once everyone began moving off campus sophomore year.

Their families would typically freak out whenever they were discovered, but by any measure, they were doing better than even two parent households who waited. 4 young educated women in the same house could easily care for 4 babies between them even working part time.

There was no reason why a beautiful ivy League freshman couldn't carry twins at 18 so long as she had friends to hold her hand and catch her babies.

Finally our parents were gone for the weekend.

It was just me and my brother, Mason, all alone. We both knew what was going to happen, I’d been bugging him about it for weeks- ever since mom told us they were leaving for my grandparent’s for the weekend.

I waited for him in my room, dressed like this, but not quite as pregnant.

He came in, naked, hard. He step toward me, giving me a big hug, his hands reaching around to squeeze my ass while his shaft poked my belly. He smiled down at me, obviously just about as excited as I was.

My hand wrapped around his twitching cock, rubbing it up and down the way I knew he liked, then kissed him on the cheek. I gave him a smile, then turned to the bed, crawling onto it on all fours, rolling my hips for him.

“Come on Mason, We’ve been waiting so long~” I murmured to him. He knelt on the bed, rubbing my ass as he slipped my underwear down, rubbing me a little.

“Mmh- I finally get to fuck my little sister,” he groaned behind me as he lined himself up. “Big brother’s going to make you feel great!”

It was so strange, when he talked like that I thought it was embarrassing, but so hot at the same time. I moaned a little as he leaned over me, starting to push in.

He was so slow, taking me inch by inch. I just focused on how good it felt, and how wrong this was. But, I wanted it, I wanted it so badly I was soaking his cock. Soon he started his slow thrust, one hand holding my ass as he took me.

Finally, after so long I could feel Mason’s cock, using me the way I’d wanted him to.

“More~” I moaned to him, turning back to see him grin. It was something I hadn’t seen before, how much he wanted me!

His hands gripped my hips like vices, holding me in place as he leaned in, driving himself into me so much harder. My moans grew louder as I rocked back into him until our hips met, filling the room with soft smacks.

“Good girl,” he cooed, leaning over me, his cum filled balls slapping between my legs. God, when he called me that it always put butterflies in my stomach, as if he owned me… I’d never realized.

Each moan was followed by a desperate panting breath… “Harder!”

It just slipped out! But he didn’t care why I said it, he was going to give it to me! Pulling almost all the way out, he slammed right back in, railing me so hard! He shoved my face against my pillow, as I squealed ecstatically!

“Little sis’ likes it, huh?” He asked. “Well?”

I nodded, too embarrassed to look back. “Yess- it feels so good!” I cried into my fluffy pillow!

He groan his sexy, melting groan as he pounded my overly tight passage, deeper with each thrust.

“God, sis’ I’m gonna cum-” he called, telling me more than warning me. Just the thought of it sent shivers down my spine, filling my head. “Cum in me- do it! Please!” I groaned into my pillow.

“My little sister wants me to put a baby in her belly?” He asked, almost too arrogantly, but I still loved it.

“Yess!”

I could almost hear him smile as he plunged down into my tight hole, cumming like a machine, pouring it into my belly~ I came so hard, it was the most intense orgasm I’d ever experienced! Clutching at his shaft, I tried to stroke him with my insides for more- more hot, brother-cum for my womb!

As we both calmed down, he stayed deep inside, rolling onto his side and taking me with him.

Now that Ive gotten bigger, how do I look with my brothers baby in me?
