Sister Impregnation Novels & Stories

“My brother, Alpha Aegon did something you must know. He impregnated you not because of love or attraction, but because he wanted you to be by his side for as long as you could. This is something you must know, Annora.” She walked to an end and turned so that she could face me again. “He found out you are mares with Kairel, and swore to not let him have you. I know you two have had a thing going on with each other even before you and Kairel discovered you two were mates, but you never got pregnant. Have you asked yourself why you got pregnant a while after yourself and Kairel discovered the bond?” She was right. How could a woman be this smart?!

What would we do if I had gotten my sister pregnant? "How can you possibly think about doing it again at a time like this, Karen?" I breathed. "Because it was so incredible the first time," she murmured. She looked down at my hardening cock and gulped, then stroked it briskly as her eyes searched mine. "In that moment, when you were coming inside me, I felt like I was completely and totally yours, Bobby. My pussy was completely full of you, you were in my arms, and you were filling my womb with all of the hot, fresh sperm it craved. It freaked me out to think that my own brother could be putting a baby in me. But...now that I've had the chance to think it over, the idea really turns me on."

"I've cum so much...I can't cum anymore! Please...please...please make a baby in me...please!" I growled and almost screamed, plunging myself as deep as I could go. I felt myself let go, spurt after spurt of my fertile seed filling my little sister's waiting and ready womb. I knew why I had chosen her first. Mama was already carrying my baby. I wanted Su to be pregnant too. I wanted it desperately. I imagined her filled with a child, breasts swollen, and it seemed like even more seed poured out of me. Finally, I finished almost collapsing on top of her.

“ this is my younger sister, Isolde. Isolde, this is my mate, Elowen and this is her sister, Layla.” A young woman came forward with a pleasant smile, yet I noticed how her eyes swept Elowen all the way up to her head and down to her feet. “So here is the one the moon goddess chose for my brother?How… interesting. I am Isolde, lovely to meet you.” I slightly tightened my jaw, but I made no comment. The voice of Kieran came in. “Introductions will be properly done later. The mating ceremony has to be fulfilled before the moon sets.”

Evelyn, as usual, was two-steps ahead, already jabbing her finger in the chest of the Alpha, who apparently was named, “Roman.” “Like hell you’re taking our sister away! I don’t care who you think you are, but she isn’t going anywhere with the likes of you!” Roman looked down on her with benign amusement and said, “She is my mate, and she will come back with me. You will not stop us just because you’re her sister.” Evelyn reared again, ready to drive her point home, when the look of surprise spread across her face, as she felt her father’s hand come down upon her shoulder. “Evie…” he said, “Your sister has found her mate. We should all be happy for this moment that she’s waited so long for.

Mary, my sister-in-law, stared at me. Her face was deathly pale. “What did you just say? Are you asking me to abort my baby? All because of what Pip said?” I gave a solemn nod. “Yes. Pip said this child is an abomination. It cannot—” Before I could finish, Mary slapped me. “Your brother and I tried for thirty years to have this child! How dare you tell me to get rid of it? If he finds out, he’d kill you, you monster!”

I try to sound humorous, but I hear my voice crack in fear. “My brother needs a biological incubator.” She says, lowering her voice as if there's another party in the car. “A biological incubator?” I frown, my brows furrowing at the weird way the words sounded. “I don't understand.” I cough out a dry laugh. “He wants someone who'd get inseminated with his genetic material and carry the resulting pregnancy to term, upon delivery, she'd relinquish rights to him.” She says more audibly, clearing her throat. My thoughts go on a merry-go-round and I throw up my hands. “You just confused me even more. Let me get this straight, you want me to get pregnant for your brother, carry it for nine months

I quickly turned back, pretending not to notice him, and tried to focus on the ongoing gossip. One of the maids let out a sharp gasp. “Did he really have to disrespect our lady by bringing her in?” “Our lady?” I frowned, piecing their words together. ‘She must mean Marielle.’ I muttered under my breath. Even though she’s not officially married to him, carrying his child is enough for her to be the lady of the house. The murmurs grew louder. “Our lady must be turning in her grave at this sight.” Someone hissed. “First, he impregnated her sister, and now he’s brought her pregnant sister into his home. I respected the Lycan King, but this is just evil.”

"I told my brother to put you on a pedestal just so he could let you fall even harder." Her eyes widened in shock as she looked at me. "You!" she shouted before collapsing to the floor, clinging to my brother's leg. But he kicked her away without hesitation. "Please, you can't do this to me... I-I'm carrying your child again... Our child..." she stammered, desperation seeping into her voice. I scoffed. "A child? Do you really think my brother would touch someone as vile as you?" Lara froze. "What do you mean?"

It has a little bulge; like I said, she's not fat, just curvaceous. It makes it really, really easy to imagine her knocked up. Knocked up with my baby. Of course, I never thought it would happen. But now here I was, fucking my own sister, trying to impregnate her. Three months ago, my sister would never have even considered having sex with her brother. To her, I was just an awkward kid who didn't know how to talk to girls. She'd get so annoyed that I would just play video games all day long, or watch p**n in my room when Mom wasn't home.
