From behind

You start kissing as soon as you're through the front door and Janalee's kisses are more insistant and hungry than Cami's and your mother's. She is some how hornier than both of them combined. Is it the pregnancy? You'd really never even thought of it until she showed up nearly naked with her swollen breasts and belly in that previous reality.

Whatever the reason, you aren't complaining. You lean into your new-found fetish and break off the kiss long enough to pull your shirt off and feel more of her skin against yours.

You start gnawing on her neck while squeezing her ass.

"Oh yes!" She says in a ragged voice. "Oh Hyrum. That's my good lil' brother! Give your sister what she needs!"

She works a hand down the front of your pants to find your swelling cock.

"Oh gosh yes!" She exclaims. "That's my BIG little brother!"

He pushes you back from her neck with her other hand and looks earnestly at you with big blue eyes.

"I need THIS" squeeze "inside me RIGHT NOW!" She tells you. "Bedroom!"

You follow her to the bedroom, akwardly removing the rest of your clothes as you do so.

Janalee has a very large bed along with a liquor cabinet that is apparently standard in Mormon bedrooms now. There's the framed Proclamation on the Family that you rewrote earlier on the wall, next to a big framed photo of Janalee and her husband Bill in front of the temple on their wedding day. You've seen the photo before, but Janalee had been wearing a dress in it before. Now she just has a veil on her head and a garter on one thigh, her naked flesh still glistening with olive oil from her washing and anointing, a square and compass on her tits drawn in white body paint.

You have only a moment to admire the wedding photo. Janalee grabs hold of your cock with one hand and strokes her belly with the other.

"I'm getting too big for a lot of positions," she says. "Do me from behind?"

"With a heart full of song!" You agree.

"That's a good brother!" She exclaims and crawls up on her bed and waggles her ass at you.

You mount her and she groans.

"Are you ok?" You ask, worried about her delicate condition.

"No, I'm fucking horny!" She exclaims. "Don't you dare go all gentle on me now, Hyrum! Fuck me like you mean it! Fuck me like a brother should!"

You guess she isn't that delicate. You grab hold her hips and start pumping in and out of her.

"Yes! Oh fuck yes, Hyrum!" She exclaims. "Oh gosh golly fucking fuck yes! Harder! Harder!"

You up the pace. She goads you on further. On a whim, you slap her ass and she gasps and then shouts "YES YES YES! More of that!"

You spank her more, then fuck her more, then spank her again, then fuck. She never knows if she's going to get your dick or your palm but she seems just as excited about both. Soon she's biting her pillow and shuddering with orgasm.

But you're not there yet. Somehow having spent the past 12 hours having more sex than you've had in your life has increased your stamina. You pull out, flip your pregnant sister on her back and then pull her around so her legs are over the side of the bed.

You stand beside her bed as she smiles up deleriously at you and take your place between her knees. She licks her lips and nods hungrily as you enter her once again, holding her knees up at the level of your hips to give yourself leverage. She mauls her tits as you thrust and thrust, her pregnant belly quivering with every pounding blow.

"Come inside me, Hyrum!" She goads you. "Come inside me! Bless me with your brotherly seed!"

And of course you do, shuddering with the power of loosing your full quiver as she cries out in gratitude.

You flop down beside her, spent, and you both pant for a while and revel in the afterglow.

"Oh gosh golly fuck, Hyrum!" Janalee says at last. "You're the best! You can't know how much I needed that!"

"Glad to...glad to help, Sis," you say, still amazed that this is your life now.

"I'll deny it if you ever tell her," she said. "But mom was right. I should have never married a convert."

You knew your brother-in-law was a convert to the church. He was from North Carolina and had taken the missionary discussions as a teenager. But what did that mean in this new world you created? How did one go about joining a church that believed in drunken **** and female exhibitionism?
