You slip out for some groceries and I slither into your apartment and do two things. First, I shrink your partner until she's only about a quarter as big as my tail is wide and swallow her whole. Second, I put a gag on the lookalike person I plucked from the street and swallow her too.
You get back and see a scalie tail leading you through your apartment and into the bedroom. I'm lounging, tits out, splayed on your bed, and you can see your partner, fighting for her life inside me.
Maybe you try to fight, only to be swatted down. Maybe you beg, only for your pleas to fall on deaf ears. I tell you to make the most of your final moments together.
You latch onto my belly and squeeze. Maybe you could use the opportunity to try and squeeze her out, but a half-assed gulp from me easily puts her back into position. Muffled screams as my digestion slowly kicks in.
You squeeze and hump and fondle your love, calling out to her how you're sorry you couldn't save her how you'll try to give her one last good feeling... all while your partner feels you raw a complete stranger 3 feet upstream. She calls out to you, tries to signal you, but she's too small. Too small to make a noticeable protrusion to tip you off that there's multiple people inside me. Too small to overcome the noises of my stomach or the trashing squealing body double above her.
She lies there and melts, knowing that your parting love and comforts are going to someone else, feeling that person's cum and molten body splash down on her, knowing your efforts, though well intentioned, were in vain.
You feel the lump beneath you go soft and cry as you come to terms with your partner becoming a waterbed of a stomach. You feel her deflate, and watch as strong pumps of fluids make buldges that move down my body and dissipate.
What you did next, be it beg to be eaten, beg for your life, crumple up and cry, was irrelevant. Two hands grab you and shove you up my sweaty asshole. It greedily swallows you up into my colon, and a jumbo plug pushes you into my large intestine. From there my muscles seize you and pull you deeper. "Don't worry", I say in mocking platitudes, "you'll be reunited with your love soon". Followed by a whisper of "for real this time".
A content burp, and I snuggle up in your bed, eating the groceries you just brought back. So much junk food, this is gonna wreck my system. Oh well, guess I can't wreck the three of you more than I already have.
