In your parents' bathroom

Your pregnant sister giggles and scampers off into the bathroom that open off of your parents' bedroom. Apparently she first fucked you in the shower you surmise as you hear the water start to run.

You slide around your snoozing mother and follow your cock as it points toward your next incestuous adventure.

Janalee is grinning hornily at you, standing with her jutting belly and boobies. She hasn't gotten in the shower yet. She holds the curtain back and waves you in. You oblige and let the warm water run down your body and drip off your hard cock. Janalee closes the curtain for a count of three, then opens it up again.

"Happy birthday, Little Brother!" she exclaims. "Am I the first?"

"I...uh...yes?" you say, realizing you must have waited until adulthood, or at least kept your family under that impression.

"Yes! Your cherry is mine!" Janalee exclaimed. "I've been awake since 4am waiting to do you!"

"Wow!" you exclaimed, flattered. "And Mom and Camilla didn't fight you for it?"

Janalee giggled naughtily.

"I got them sooooo blessed while we were making your birthday cake, I don't know if they'll be up by noon," she said. "So I'm gonna do you six ways to Sunday!"

She steps in the shower, grabs ho!d of your cock, leans in and kisses you. You kiss her back, your tongues playing as the warm water pools between you.

Janalee breaks off the kiss and says "OK, Hyrum, recreation is great, but given the state of my belly, I'll need skip to the part where you toook me from behind, kay?"

"Okay!" You agree and she eases past you to put her hands against the wall and let the shower run down her back. You guide your cock into her cunt and she grunts her approval. You proceed to fuck her slowly but thoroughly, probably not at all like you did the morning of your birthday, but you've got more experience now, and Janalee certainly isn't complaining. She diddles herself and moans as you push in and out of her.

You notice the ball-shaped cap of the shampoo bottle hanging in the rack from the curtain and grin wickedly. You grab the bottle and press the round cap against Janalee's assholes.

"Oh fuck, Hyrum!" she exclaims. "Oh fuck yes!"

And then she's gently cuming, mewling like a kitten as she does so. You join her, pumping your spunk into her, confident that you can't get her any more pregnant tjan she already is.

At last, you pull out and she shudders, tuens about and hugs you gratefully.

"You have no idea how much I needed that!" she exclaimed.

You turn off the water and then help her dry off.

"I could use a nap after that," she confesses. "Maybe I'm more like mom than I thought."

"Nothing wrong with that," you say. "Mom's an incredible lay!"

Janalee giggles.

"You're so sweet," she says, then kisses you.

"You can keep Mom company," you say. "I've got some things I need to look into."

"Oh...okay...you don't want to nap with me?" she pouts.

"I'm not pregnant or 'blessed'" you point out. "And i really do have things to do."

"That's fair, I guess," she concedes. "But maybe another round later?"

"Definitely!" you agree.
