Katie crawled into the bag when Calvin held it out to her. And then, he took his shirt off. She'd seen him without a shirt on before-- they'd gone swimming together a few times. Mostly, to Katie, boys all looked the same without a shirt on. It wasn't that big of a deal, but her heart sped up nonetheless.
"Well, if you're going to take yours off, then maybe I should take mine off...to be fair or something..." Before he could stop her, she sat up and tentatively peeled off her tank top until she was sitting there in just her bra. She blushed again and dropped her shirt on top of his before settling down again. Her heart wasn't going to stop racing anytime soon, and she realized that the moment their skin touched. It was even more electric than his touch had been before. He was warm and soft and Katie couldn't help it as her hand moved across his stomach and chest. She wanted to explore every inch of skin he had, but only because it was so new to her.
She cleared her throat self consciously. She wondered what he thought of her and decided to ask.
