By Being Naked

Lex smiled as he looked at Kara. It's been a week since his lie and things were already working perfectly. She wasn't wearing clothes at all anymore. He even checked her room and she got rid of all the clothes in her closet.

One day, he'd stop with the tricks. He won't use small amounts of Kryptonite to make her think she's allergic to clothes. By that point, he won't need to. Even after he 'cures' her allergy, she'd be so used to going naked that the thought of clothes would just make her uncomfortable. Meanwhile, she'd still praise him for trying to make a cure and he could pressure her into wearing some very slutty outfits.

But that wouldn't happen for a year at least.

For now though, he was still happy with the results he was seeing. It was even cute to watch her cover up with her hands as she walked and flew around the building. As Kara approached, Lex said "Kara, I know it's embarrassing but what did I tell you about covering up?"

She blushed as she slowly put her hands behind her back, revealing her bare body to him. He was careful not to accidentally touch her pussy or breasts, as he slowly touched her thigh and moved his hand up towards his head.

"You are incredibly beautiful..."

"T-Thank you, Lex..."

He couldn't help but smile as he noticed Kara getting wet. She was way too easy to manipulate. The fact that he was having trouble with Superman, someone that people viewed as a walking god, while he was easily turning Superman's Cousin into his slut, was shocking and made him oh so satisfied. His favorite part was using her to mess with Superman.

Despite Superman's best efforts to tell Kara the truth, she never believed him and Superman could never find kryptonite on his body so he wasn't able to prove anything either. No matter what happened in the future, this would always be one victory he had over Superman and he loved it.
