She spread her legs, and her pussy, still soaked, became visible. "Do you want to cum in my pussy too?"

I swallowed, then nodded. "I...I do."

She bent her head, giving my cock a few quick sucks, to return it to full hardness. It didn't take long, as I smiled a blissful smile at her. She straddled me, and held the cock upwards, as she guided it to her pussy.

"Wait..." she said. She leaned to the side, and a lamp came on. I now saw her clearly for the first time.

"I want to SEE you now, little brother...!" she whispered, as she leaned back again, and slid my cock inside her.

I felt her pussy taking me in, and closed my eyes a second...but then opened them again. Enjoying the sight of my sister as she began riding me.

"Oohh god...I've wanted this...so long...!" Katie gasped, as she slowly slid my shaft in and out of her. "I...I had..planned...the young guy...tonight...to cum inside me...and..mmhh..make me...pregnant..."

She threw her head back, grabbing her breasts in her hand and playing with her nipples. I widened my eyes. "What?"

"I want you...to knock me..up...will you...do that?" my sister groaned.

My mind exploded, but an overwhelming lust seemed to fill it right back up and I gripped her hips as she gyrated on me. "Oh god Katie...oohh yes...I do....I will"

She moved faster, her eyes locking into mine. "Yes, please...knock me up little brother...mmhh"

I thrust upwards every time she went down, feeling how my cock went deep up inside her, almost impaling her. Her eyes were half closed, but kept focus on me.

"Fuck...fuck my pussy...fuck your slutty sisters CUNT!" she moaned, obviously so turned on by this, she was swearing now, "fuck me and make...nnhhh.. a baby...in me....!"

The talking did it for me, and for the 3rd time in an hour, I felt my balls explode. This time, the seed filled my sister's womb, and I could almost feel it flowing deep, deep inside her, hooking to her fertile egg.

She collapsed over me, her won body trembling as she came from my heat inside her.

She rolled her arms round me, and we lay there, on the bed.

Siblings, but now more.

Perfect Sibling Prenancy Story.

Usually stories lack exciting outcomes,but to have a sister who secretly fantasize about her younger brother enough to allow some stranger to come and fuck her anonymously and possibly get her pregnant is risky beyond hell,but to find out that it was her sibling makes it just sheer perfect.

Even tho she is a college student made Katie a wild,adventurous,pregnant,incestuous anal whore she is the epitome of a wonderful woman who is ready to start a family,and who better than with her brother Brian. Overall both Katie and Brian can use the excuse that Katie got pregnant by some jock but in actuality it will be her brothers babies and could tell their Parents that Brian wants to co-parent his so-called nieces/nephews but actually his/their siblings and keep it a secret.Damn I love this story.

Would have given 4 stars

Loved the story until the end where sis says she wants him to get her pregnant, that was kind of turn off. Other than that really enjoyed.

Fun filled fantasy! All the stuff written below didnt bother me really since its obviously out there, lol. My only real gripe was the conversation during sex. It...was...just so...annoying...the...way it...was...written! Lol. Yeah, even if Im totally winded from pounding into my girl for a good while, its still no problem stringing words together when I talk, hehe. It made it hard to read since I always mentally translate what Im reading to how it will sound in my head. (Does everyone do it?)

The other thing that made me cringe was fucking her pussy after being in her ass...I know she said she was clean (assuming an enema before) but still, gives you the real world mental shudder, hehe.

Fun story! (Typos and all, lol;)
