Sponge Thong

James decided to try out the thong he had recently purchased, just to see how it looked and felt in his pool. It was a new style, a 'sponge thong', but he had no clue why it was called that. The thong seemed to stay in place as he swam, which was good, and despite being white stayed opaque while wet.

He remained in the pool for a little while longer, enjoying the sensation of weightlessness in the water until he began to feel odd. His movement seemed more restricted, almost like his body was an inflatable while his thong became a little uncomfortable and tight.

He stepped out of the pool and began walking toward the shower, his steps strangely heavier as each one sent a ripple through his body, his cock bouncing along. He reached the stall, turning the knob before stepping into the fresh stream. As he let the water envelope his body, he noticed something strange. Despite feeling the water washing over him, the streams that formed never seemed to run off his legs, his feet left dry.

He looked down at the floor, noticing no water running down the drain. Then he saw his body, and everything made sense. His body was swollen huge, his muscles chafing against each other as he moved, soft and bulging. As the stream hit him, it immediately soaked into his body like a sponge, his skin shimmering with a sheen of moisture as his pores held in the droplets. His stomach and chest pushed out further and further as they absorbed more fluid, his paunch forcing the thong tighter and tighter around his waist.

That's when he felt his bulge. He could no longer see it under his new paunch, but he felt it, a hanging sack slowly growing larger and larger, hanging lower and lower. He could feel it halfway down his thighs, a giant heavy growing balloon compressed by his thong that struggled to contain the growing mass attached to his groin.

That's when he began to feel pressure building around his lump of a sack. It felt like a grip tightening around his balls, the elastic of the fabric no longer expanding with his member instead squeezing around his jewels like a cage. It quickly became painful, feeling as if his bulge was about to pop when a stream forced itself from his tip, eliciting a moan from his lips as fluid began pushing itself from his cock relieving the pressure.

The flow grew in strength until a constant stream was seeping out from his thong, squeezed out of his body by the limited elastic. He felt fluid begin to leak out of the rest of his body, his skin saturated unable to hold any more. It felt like an orgasm across his entire body as fluid dripped from every pore, spilling out of him uncontrollably.

He had never felt so alive. He stayed in the shower, allowing the water to keep soaking into him and cascading out, feeling like a new man as he enjoyed the sensation of his body expanding and growing.
