"She won't be much trouble," your wife tells you. "She's a bit lazy, sure, but she's pregnant now so she has a good excuse. But I don't mind looking after her; I'm used to it. And she'll keep out of your way if you want her to..."

"Babe," you say, bemused, "I don't mind. I like your sister."

"It's just I know it's a lot, having someone else in the house for so long," your wife says. "But she's got nowhere else to go, and with the baby on the way she needs help..."

"It's fine, really," you say. "It'll be nice to have her around."

Your wife beams at you and kisses your cheek. "Thanks, babe," she says. "I promise we'll make it work. And we might have to be a bit sneakier about sex with someone else in the house, but I'm sure we'll still find a way for you to get what you need."

Your mind wanders to your wife's little sister - to me. Younger than your wife but with bigger tits, a fatter ass, thicker all over and damn proud of it. Those bulging curves have been the subject of many a fantasy for years, and you can only imagine how the pregnancy will affect them. With your wife in the office and you working from home, you and I are going to be spending a lot of time alone in the house together. Yeah, you can definitely think of some ways for you to get what you need...

Hey! I'm your wife's little sister, a slutty lil single-mom-to-be with an absolute shedload of the right curves in all the right places. Those pregnancy hormones are driving me crazy and making me fucking insatiable, and I know exactly how I want to satisfy my cravings. I love the thought of getting bigger and more irresistable over the course of my pregnancy and my stay with you. I like the idea of my big sister taking care of me while I take every opportunity to fuck her husband. Maybe she's okay with it, maybe we go behind her back, maybe she loves to watch - I'm open to a lot of different approaches. The main things here for me are the insatiable sluttiness and the outrageous thickness. Other than that, if you have any particular ideas for how you'd like things to play out, let me know!

Kinks: (none of these are mandatory, but if any take your fancy, let me know) cheating, sluttiness, nymphomania, pregnancy, breeding, birth, abortion, weight gain, feedism, laziness, slob, alcohol, public sex, risky sex, cuckquean, body worship, likely plenty more.

Limits: animals, bathroom, vore, feet, raceplay.

Hope to hear from ya <3
