After experiencing one of the most embarrassing moments in his life, Ryan finally arrived at the beach where Madison was already waiting for him. The beach was crowded and all kind of people were having fun at sea, sand and building nearby. Ryan wasn't a fan of beaches and even less in his current situation. But he knew that Madison loved it and she's surely planning something to humiliate him even more.
"Oh, good. You reek so bad!" Madison told Ryan while she approached him with some fingers covering her nose. "You smell like a gas station restroom." Despite Ryan didn't answer, she smiled satisfied because she can notice the humiliation on his face. "Let's do some more changes, but this place is very crowded and I don't want to get some attention on myself. Let's go over there, behind those palm trees."
Ryan followed her and when they're almost out of people's vision, she started to turn around Ryan and checked what she's going to do now. "Ok, first. That brief is going to morph into a red poser. If you don't know what a poser is, it's like a speedo but with less fabric." Almost immediately, the white cotton fabric started to change into a red latex one. Some areas vanished completely, giving him just enough fabric to cover his junk.
"Ok, that's fine. Now everyone can see your boner from any angle but to make it more noticeable I want it to grow to 12 inches and thick as a soda can. Your balls will be as big as lemons and you will cum every 10 minutes no matter how hard you try to avoid it." When she stopped talking, her changes started to happen on Ryan who can't help it moaning in intense pleasure.
"Please, Madison!" He pleaded with tears of shame coming from his eyes. His average adult dick was painfully swelling so much that he thought it's going to explode. It was monstrously growing bigger than any other dick at the beach and the poser was getting so tight he was getting a wedgie that hurt his butt. "I'm so big!!" He kept moaning while his balls swelled as well until they're so large that they're coming out from the sides of his poser.
When he was done growing, he grunted in displeasure while cummed. A thick wet spot appeared on his power but his erection didn't went down. His face was red of shame but at least he had the small comfort that nobody will recognize him in his current status. Madison was hardly trying to contain her laughter, so she took a deep breath before she started to make fun of Ryan.
"Don't ever think of running away or do something against me because I have a 100% control over you, little bro." She said while she grabbed Ryan's testicles and squeezed them like a dog's ball to reaffirm her dominance over him. Ryan can't do anything but groan in a mix of pain and pleasure. He can't understand his feelings right now, to him everything was so weird and new that he felt even more helpless than Madison thought.
"Now, what's next?" She asked herself while she looked around wondering about what to do or how she can humiliate Ryan even more. 10 more minutes had passed and Ryan cummed once again. "This is going to be a long day..." He thought while he watched a the wet spot and drops of cum falling from his reduced clothing.
