Maya struggled weakly as the guards hoisted her massive marshmallow form toward the towering tube. Her plush, obese body wobbled with each step, every jostle pressing her soft curves against the restraints. The tube loomed above her like a chocolate waterfall ready to consume her entirely.

“Please… I don’t want—” she squeaked, her voice muffled by the weight of her own body.

Without waiting for consent, the guards activated the tube. Warm, thick chocolate surged upward, sloshing into the opening at the base. Maya yelped, the rich liquid forcing its way up her plump backside, filling her belly and cheeks until her marshmallow body expanded further, wobbling uncontrollably with each new layer of chocolate.

Her arms and legs quivered as chocolate seeped into every curve, pressing her softer parts together. Each squelch echoed through the tube, the sound mixing with Maya’s muffled gasps. She wriggled, trying to escape, but the chocolate held her fast, molding her swollen form into a perfect, gooey, morbidly obese chocolate-stuffed marshmallow.

“Ah… too much… oh god…” she whispered as the final surge filled her completely, leaving her a quivering, decadent confection trapped inside the glossy tube.

By the end, Maya was no longer just marshmallow—she was a chocolate-packed, oversized treat, her body stretched and weighed down, wobbling with every small movement as the guards looked on with satisfaction.
