Chris decided against adding a single fetish. Mental changes like that could be extreme, making him a slave to whatever random fantasy that was afflicted upon him. Even worse, it could be a fetish for something truly strange, such that he'd never live a functional life if such information was found out. Likewise, body odor was a dangerous game to play. People rarely ever smell themselves, and he really didn't want to become naturally pungent. What if it became too strong for deodorant to mask? He'd become an outcast.
Body hair and penis length were also out. The physical changes to his body were just too unappealing, and he was already having slight trouble with his package while seated. That left only increased fluids and sex drive, since neither would have a physical impact. However, he couldn't take a single point of sex drive, or else it'd probably be no better than gaining a new fetish with how sex-crazed his mind could likely become.
Chris carefully considered increased fluid production. It would certainly be more messy during his alone time, but he'd walk away from this without anything immediately noticeable about his figure. He could temper his sex drive, especially if the results were a turnoff. He wasn't sure if five times the mess was going to be a problem, but it'd have to be better than ruining all aspects of his body just enough, or ruining his mind with fetishes or increased libido.
He turned to Madame Illusia. "I've made my choice. All 10 points into fluid production."
Illusia clapped her hands together and flourished her arms in an exaggerated way. "Very brave of you! Most times, the contestant sticks at least a couple points into other categories to spread them out. In fact, I'd say you're quite ballsy..." As she spoke her last sentence, Chris started to feel a strange pressure within his groin, or more specifically, his testicles. "Now, witness Chris's second puberty!"
The audience rapidly grew quiet while Chris began to feel the pressure grow even more, like he hadn't jerked off for a few weeks. It quickly graduated into an acute physical awareness of his testicles. Every time they so much as touched one of his thighs, it felt like they were primed to explode. The weight of his testicles even started to feel physical, pulling down on him.
Chris tried to muscle through it without touching himself on stage, but he was already naked in front of this crowd. He moved a hand quickly to his sac to try to massage the pain away, but accidentally struck his balls! They were unexpectedly closer to his hand than he'd expected, and his hand didn't feel like it was the right ratio.
Looking down, Chris came to a horrible realization. His balls were physically growing by the second! They were more than three times as large as before, and they were still growing. Each testicle was easily as large as a baseball. "What are you doing to me?!"
The growth and pressure immediately stopped, and Illusia refocused on him. "Why, my dear, I'm increasing your fluid production! How else did you think you'd get 500% more fluids produced?"
"Make it stop!"
Illusia gave him a sour glare. "I was nearly done with your change, and you not only spit upon my gift, but you also demand more from me? Such disrespect is deserving of punishment." She snapped her fingers, and unlike before, Chris felt a terrible pain in his testicles as they near-immediately doubled in size once more.
His balls strained, with the bottom of his scrotum hanging nearly to his knees. Even though his penis was large, it looked small relative to the grossly over-sized testicles he now sported.
As he collected himself, Illusia bowed to the audience. "Now, let us see what Chris's dear younger brother, Craig, thinks. What would you like to see added to Chris? Is this enough, or should we go further?"
