"Hey, uh," Nina said and then paused, biting her lip. "Kelly, we've seen each other naked before, right? So it's not weird if we get naked together now, and just, you know, check everything out?"
Kelly wasn't sure how to respond, but she felt her dick throb harder than ever. "Don't you feel gross?"
"I'm tired of feeling gross!" Nina opened up her towel, presenting her nude body to her best friend. "Let's check each other out, maybe see what outfits we look cute in now, you know? Just like we always have."
Kelly took in the sight before her. She couldn't help but focus on Nina's penis. It was smaller than her own, but Kelly suspected that her own cock was actually kind of big. She sighed and stood up, walking up to Nina.
"Fine," Kelly said, as if she was making a sacrifice and not at all satisfying her own curiosity, "Let's see what you've got." Kelly dropped her pants and showed off her own hard dick. Nina was shocked at Kelly's size and dropped to her knees in awe.
"Holy crap, Kelly, how did you hide this thing at school?" Nina measured it up against her forearm and said, "This has got to be at least 8 inches!"
Seeing Nina kneeling in front of her cock was stirring something up in Kelly. Her feelings were confusing, she had never felt attracted to Nina or any other girl, but she wasn't really sure that Nina could even be called a girl anymore. She was a cute, feminine boy now. Not that Kelly had ever been into girly boys, but it was something she could start to wrap her mind around. A cute boy sucking on her huge cock.
