I've been thinking about this all day and just need to get it out of my system
"Just a couple more bites sweetie! You're soo close"
You're pinned to the bed, your weight has gotten out of control lately, packing on at least 12lbs a month and closing in on 400. Your growing gut has been stretched to it's limit so often that it's dominating your frame, so now as you're leaning back into pillows against the headboard you don't think you'll be able to move for a while. Slowly you open your mouth as your wife pushes another forkful into your mouth, your head is so foggy from overstimulation that you can't recall what you're eating, all you know is that it tastes sweet.
Shes rubbing her free hand in circles across your fattened middle, pushing and prodding the places that typically elicit burps but now it's just groans and heightened breathing. She lifts the fork again
"I promise this is the last bite baby, be good for me and open up"
She's staring into your eyes with a pure lustful determination, her breathing is hitched and you can feel her dripping onto your thigh. You open again and she slowly pushes the forkful in, sealing it with a kiss as she drops the fork back onto the plate, both her hands end up on your love handles as she leans into you, planted her lips across your chest. The last bite is slow and painful, it's sweet but you're so stuffed it doesn't register as food by this point, just a mass made of calories that is difficult to swallow. She notices you taking your time chewing it thoroughly
"Aww come on now, you got it, just let it slide on down"
You do as she says and groan loudly as she hugs your belly tight and grips your deepening back rolls. Youre just sat there, propped up as a toy for her enjoyment, her slipping words into your ears about how good you did for her and how fat you're getting. She pulls out lotion and oil, lathering up her hands and diving between your rolls and over the dome of your gut as you moan and groan the whole time.
About 15 minutes pass before your belly has calmed down, she just can't take it anymore and takes her bra off and pulls her self closer to you and raises her body up, breast right before your eyes
"I know you're stuffed babe... And I know we pushed you pretty hard tonight but... I promised you that was the last bite... I didn't say you were done yet..."
Her nipples are leaking, thick white droplets forming and falling from her breast, before you even have a chance of protesting she leans into you and presses her tits in your face before grabbing the left one and positioning it in your mouth. Instinctively you latch on and begin to suck, the milk from her other breast is dripping onto your chest. She coos and encourages you to drink your fill, grinding her sopping pussy against your thigh, each swallow hurts but it's worth it, you're getting fat off of her love and you know there's nothing she enjoys more than her body being able to provide that. Whether it's bringing you another plate of food as you're stuck on the couch, or her breast swelling with milk and draining down your throat. There's no difference to her, as long as you're growing, she's happy
Once her left breast is empty she quickly replaces it with her right, grabbing your hand and lifting it to grope her left. You're so deep in your hedonistic haze that she knows she needs to guide you through it, she needs to be your light bearer and guide you to the finish line. Your stomach is at capacity now, you can feel her milk going down and not reaching your stomach, it's just getting caught between mouth and gut. Each time your mouth fills and you try to swallow you only get half of it down before needing air and the rest spills out and cascades across your globular form.
By the time you've finished being topped off by her breasts you're fading in and out of consciousness, awake for a moment to see her desperately rutting against your thigh before passing out and waking up to see her slowly rocking back and forth, groping her tits and your stuffed middle. Like a slide show going forward a slide and back a slide over and over. You don't know how long she had her way with you, but by the end of it you heard her squealing and moaning without a care in the world before she fell into the bed next to you, snuggling up as close as possible and caressing your swollen middle as you both blissfully let sleep take you
