You were too late. Jim jumped up in the bed at you bursting in.
"Ahhh, what's going on?!" he moaned at you. At the end of the bed under his large feet (the ones that used to be yours) a rather athletic and hairy man was kneeling and gasping with pleasure. His nose was pressed against Jim's soles. He had a hypnotic expression on his handsome face which looked more and more like cotton by the second. You tried to pull the naked man away, but he resisted every effort to move him, and with Jim's weak body you were no match. The man's big cock was shooting jizz as his body began to quickly shrink. His large hairy feet, arms and legs were turning to cloth.
Jim could barely speak, his own power was overwhelming him. "What... am I doing to him? Awwwww!"
You both were helpless to watch as quickly the man became nothing more than a pair of socks. Just like Mike from the store had warned. They huge, loose, black, sport socks were at least a couple sizes too big for Jim as they wrapped around his feet. Then, instantly, you heard Jim's feet crack at the same time as he thrust into the air and shot a huge load, yelling, "AHHH! My feet! Ah! Fuck!"
You watched as Jim's feet slowly stretched. Jim was adapting to fit the socks, and he seemed to be enjoying it, even if he was confused and resistant to what was happening. "Ahhhh!" Jim came as his toes cracked and grew impressively, just like his soles which also grew to fill and stretch the socks tight. Eventually it all stopped. Jim huffed like he'd ran a marathon. You were horrified, though grateful that the worst possible outcomes seemed to be averted. It would be annoying but you could deal with having size 14 feet, you told yourself. But before that, you had to convince Jim to return your body.
You resisted the urge to be angry and asked Jim for him to cooperate in returning your body, explaining what had just happened to him.
"So Mike was telling the truth about that hypnosis and transformation stuff then," Jim said. He pulled one of the socks off and wriggled his much larger, hairier toes, "I like it."
"What!?" you replied angrily. For a moment you stared at Jim's feet. He seemed to have an exact replica of the hairy, athletic man's feet.
"You heard me," Jim said bluntly, "Now, what do I do with you?"
Jim's massive feet were hypnotic, exactly like Mike said would happen. You stared at the huge soles for a moment. "Resist..." you repeated in your head.
Jim smirked at you, knowing what you were thinking. If you stayed too long, or looked at Jim's feet, even accidentally, it could all be over for you. But you really wanted your body back, by any means necessary. So you...
