Having incredible sex with your mom before getting stuffed down her throat wasn't a bad turn of events, but you weren't planning on letting her absorb you before one of your paying clients gets a chance. "Okay, Annie. What do you have in mind."

"Well, first of all, unlike you, mom can't digest me." She cups a puddle of stomach acid into her palms and rubs it all over her chest. Indeed, the acid wipes off without a burn. Your sister might have more talent than you thought! "Long story short, this isn't my first time in mommy's belly."

"Ok, so you'll get out of here fine." You give her a cynical jab. "But how does that help me?"

"It's simple." Annie scoots closer to you, placing her hands on your reddened shoulders. The sweat-drenched black hair draped over her eyes can't mask the sudden maturity you see in her gaze. "The only way to get you out of mom, is to get you into me."

"You mean you got yourself swallowed by mom just so you could vore me?" You shoo Annie's hands away from you. You should have known this was coming. Your sister has been trying to eat you since she hit puberty and now she's caught you in the frying pan.

"Listen, stupid!" Annie strikes back, still determined to rescue her brother. "As long as you're inside me, mom can't digest you. Once she lets me out, I'll let you out and you can get back to being eaten by crazy ladies for cash!"

You think on this for a minute. Of all the wild stuff that's happened in the past hour, you still haven't earned a penny towards that game system. "Ok, so eat me."

A surge of glee shoots through Annie, finally hearing you invite her to eat you. Then she remembers what's most important. "Wait, we have two choices." She goes on. "I can eat you and keep you in my stomach..." She pauses to rub her slim belly, already loving the thought of stuffing you into there. "But you don't know how mine works. I might end up digesting you if we're in here too long. And I don't know anyone who will come diving down my throat to save you again."

"Point taken. What's the other option?"

Annie clears her throat, regaining her rosy blush. "Or... I could unbirth you." She says shyly, spreading her legs as far as the stomach will allow to give you the first real look you've had at your sister's pink slit. While much smaller than your mother's, it does look inviting...

"Well... There's no risk inside your womb, right?"

"No, it's just..." Annie spreads her lips apart with both hands. You see that her young vagina doesn't open wide enough to fit your head inside, never mind your entire body. "I'm still a virgin. I've never put anything bigger than my finger in there." She sits back up to face you, her hands drifting along your sides as she eyes you with a seriousness you never knew your sister could possess. "The only way I can fit you in down there... Is if you and I have sex first."

Your heart jumps to your throat, practically choking you in its inertia. "Annie, that's crazy!"

"You had no problem doing mom! I saw the mess you left myself." She gives you a jab to the side. "I'll probably end up with a younger brother thanks to you! At least with me you don't have to worry about making babies yet."

You are about to be digested and your only chance to escape is to either let your sister eat you or have sex with her inside the body of your mother! "Isn't there another option?"

"You have to get in here somehow..." She pats her belly, just between her stomach and womb. "And I am NOT sticking you up my butt!"
