Click here"Ha. Ha. Ha. Very, Very funny, big sister-of-mine. I was talking about the former: just your genes and my genes. You don't have our baby growing in your uterus and there's no way you could know yet even if you did."
Marissa smirked and sat up, spreading her legs again languidly. "Hmph. Maybe. Well, considering what's at stake for you here, would you care to lick your brotherly splooge from my pussy lips, or should I just rub as much of it back into my fertile little womb as I can while rubbing out one last taboo orgasm?"
Jesus my sister was a sexual fiend. She might've technically been a virgin before all this, but she clearly knew how to have a good time with her partner, regardless.
"You know, it's supposed to be the younger sibling that's the spoiled brat, sis," I offered weakly, as I knelt between her legs.
The dark blonde tuft of pubic hair above her snatch was shaped like the most petite little heart-- I don't know how I didn't notice earlier. It must be the angle, because staring directly into my big sister's cooch, I realized how much I did actually love what my life had apparently become: a twisted sex-romp with a big sister who I might have turned into a baby-mama.
What can I say?
It just sorta happened.

Frankie195228 days agoLove it. More please. I am eager to know what happens from here. Is Marissa pregnant? Does she birth the baby? do they somehow stay together and make a family. what is the parents reaction going to be?
Anonymous4 months agoI enjoyed the first page and the initial sex.
After the brother cums inside her I completely lost my interest. Women who unilaterally assume the role of victim are not sexually attractive to me. Those who do it when there is no victim or perpetrator are scum. Immediately going to rape and using it as a 'joke' is not ok. Using it in the context of this story is even worse.
What was a romantic one-page wonder was turned into an abusive family dynamic where the sister preys' upon their combined state of 'wtf' to browbeat, cajole, blackmail, shame, and guilt the brother into a submission position using loving familial bonds.
Anonymous7 months agoKrazycumbucket claiming to be a doctor then stating with no room for argument that no cock is over 6 inches 🤣 you are as delulu as Marissa my love. As a woman I can assure you that I can fit more than 5 inches inside me. But you continue to mansplain the female anatomy to me. LOUDER FOR THE MEN IN THE BACK... we push out full mini humans, your tiny baby dick ain't gunna do shit
Anonymous12 months agoI think I started giggling somewhere around "my virile jizz" and never fully recovered. Is this a parody of a 70's Beeline novel?
Anonymous12 months agoKrazykumbucket is just trying to make himself feel better about his own tiny dick. That or he's a doctor in munchkin land.
Niceguy200012 months agoReminds me of Spector Dugan stories where the big sister is the brighter one.
A good first attempt.....nice try at humor and SD-like warmth.
syd_v63about 1 year agoWhile I loved the premise of this story, the Author lingered too long in fleshing out the discussion of their conflict. I say that because the resolution was vague as the sister waffled too often and too easily. Perhaps if the discussion lead somewhere the story would feel more resolved in its conclusion. I kept waiting for reengage with the protagonist sexually as confirmation of where she stood in their relationship. It seemed just continual circle around what the next steps were without really making a choice. This unfortunately gave the story and artificial feel. These two are at a crossroad and at the end of the story nothing seems resolved. In reality there would be a made dash for the couple to go to a pharmacy even if it was twelve hours away. If that’s not the choice and the two just seem to acquiesce and this is not an “Oh well” moment in their lives.
KrazyKumbucketabout 1 year agomaybe you clowns should get a measuring tape, and look at what 8 inches or longer really is.
FACTS are: https://www.medicalnewstoday.com/articles/271647
Anonymousabout 1 year agothe average length is 5.16 inches. If you have a 7 inch penis or longer you are in the top 2% of men. That said its a story and can be whatever the hell an author wants it to be.
Anonymousabout 1 year agoKrazykumbucket, you must live in a little penis land. I was in the military for 12 years and i work in a hospital. There's plenty of 8 and higher inches out there.
