Jake's heart raced as he tore open the package, his fingers trembling with anticipation., the sleek, metallic device gleamed in his palm, promising a new level of pleasure and performance. He slipped it on, feeling the cool metal conform to his cock...
As he settled in for a night of solo exploration, Jake noticed something peculiar, his cock began to twitch and bulge, growing larger by the second just as the advertisement had promised! However his dick wasn't the only thing growing bigger, he could feel the same feeling coming from all over his body, his whole body was growing bigger!
He watched in amazement as his biceps swelled, his chest heaved with each breath, now broader and more defined than ever before, but it wasn't just his upper body that was changing, Jake's legs thickened with newfound muscle mass, his thighs pressing against his growing balls now filled with gallons of cum waiting desperately to be released
The sensation felt more amazing than anything he had ever experienced before and he wasn't even done growing just yet...
