The Harness

“I dunno, it seems a little big. Are you sure you can’t take it in anymore?”

“I’m sorry sir, this is as tight as I can get the straps,” the clerk said with the fake apology only those who work in retail can truly master - even retail stores that specialize in selling leather gear. “I’ll see if I can find something smaller.”

“Thanks,” Jeff murmured his reply and turned back to the large mirror in the change room. He looked ridiculous with the leather harness hanging from his lithe frame like an empty fruit basket, straps hanging loosely at his sides. Well, barring the one that connected to the cock ring, which was also somewhat roomier than he’d like. He didn’t blame the cock ring though - he’d always felt he could use a little more girth in that department. In every department, if he was truly honest.

Still, he liked the idea of wearing a harness and was surprised to find a local store that would allow him to try one on. Even the kind with the extra strap that connected to a cock ring down the front. Jeff had always found the whole effect to be intensely masculine, especially when worn by a big man.

Just as the thought crossed his mind, Jeff felt something strange course through him. Not quite a chill, but neither was it a hot flash. Then he felt it again, only this time it felt like a punch to the gut, but from the inside. He doubled over clutching his abdomen, the loose harness straps dangling below his jackknifed torso.

After a moment the pain subsided and Jeff straightened, wondering what had come over him. As he lifted his gaze he caught sight of himself in the mirror and noticed that he seemed to take up more of the reflective glass than a moment ago. He removed his hands from his stomach and saw he no longer had a rippling six-pack but the beginnings of a well-fed beer gut. His face had lost some of its angular features and everything seemed to have softened. He noted - with some excitement - the straps of the harness didn’t quite hang as limp and loose at his sides any longer, although they were still quite slack.

Then he felt his body lurch so violently he was forced to take a step to steady himself. He thought he might lose his lunch, but it subsided after a moment as well. Again he centered himself before the change room mirror and saw that in that brief moment his small paunch had turned into a substantial gut. The rest of him had grown as well, his limbs all having thickened appreciably, the general contours of musculature still present but none of the definition.

Even with his newly acquired thickness, the harness was still not even close to fitting. Then Jeff felt a lurch again, smaller this time but far more insistent, like a cramp that he couldn’t stretch. It was uncomfortable in the extreme, but as he watched his grimacing face he saw it swell as though stung by a bee, his cheeks puffing up and widening his face to the point it pushed his earlobes aside. His neck then followed suit and Jeff could feel the skin at the back of his skull bunching up as folds of flesh appeared there.

At the same time the rest of his body grew even wider, his shoulders and back becoming impossibly broad as his belly surged forward, his pot becoming a real tank and causing the front strap to go taught with an audible “thwack” of leather on meat. The straps that had once been limp and loose began to climb up his sides as Jeff’s body thickened, until eventually catching on the shelf of his chest. His formerly flat chest grew two fleshy peaks which were both cradled and even supported by the harness. Soon he had a pair of perky man-tits topped with thick cocktail wiener nipples that jiggled with every move Jeff made.

His neck had grown so wide that the straps that went over his shoulders now touched his trunk, while the straps that girded his chest could only be seen as they connected with the ring on his sternum, the rest concealed by the fold of fat that ran from beneath his tits all the way to the center of his back. The strap that ran down his front had become taut, even tight, cutting into the bottom of his soft and sagging belly.

Even with the benefit of a mirror, Jeff could now hardly see the cock ring the strap connected to, but he could feel that it too had become much less roomy than before. He could see two lemon-sized balls hanging low in a loose sack, and idly wondered how he’d ever get the cock ring off with balls that big.

Just then the salesman returned, a look of mild surprise on his face. “Oh, well, looks like it actually fits you perfectly, doesn’t it?”

“Yeah,” Jeff replied, the sound resonating in his barrel chest before being emitted in tones far deeper than he remembered. “It might even be a little tight.”

“Nonsense,” the clerk replied, grabbing the front strap and giving it a tug. The harness gripped his now enormous, fleshy body like a giant hand, causing his entire form to jiggle and quake for moments afterward. His balls were still swinging even after his tits had stopped dancing on his chest.

“See? Fits like a glove.”

Jeff couldn't deny the salesman was right.
